I'm creating this thread based on what i read here: http://briefmobile.com/cyanogen-demonstrates-quadrants-flaws
I'd really like to know what lagfix gives me the best results and i lost my faith in quadrant. Are there any decent alternatives? Most benchmarks i know are only good for testing cpu performance...
Its not fair to say that quadrant sucks, and particularly I don't like that the article seems to be implying that the lagfixes that a lot of us are running are simply artificially inflating the SGS's score. The SGS has the best harware on the market crippled by bad firmware, and tbh I think its the lag fix that has allowed the hardware to be reflected in quadrant scores.
Anyway, quadrant doesn't suck. Its not perfect, but it does help you determine for example, how different ROMs on the same device compare for performance, as well as showing off things like GPUs that often don't get seen.
However it just runs a series of tests and weights the results accordingly. Particularly, the I/O seems to be given a lot of weight and so can be nobbled to increase the score. However, as anyone who has experienced excessive lag on their SGS can attest, it also works the other way. Without the lag fix, the SGS is a very pedestrian device, as the ~1000 quadrant scores tell you, while with the fix it FLIES.
Actually, some people are saying they notice no difference with the lag fixes it seems. And I've also seen forums full of people saying they can hear the difference between WASAPI/Exclusive audio and shared audio in Windows. Amazingly, out of the dozens of people trying to destroy me and demand it was implemented, none of them were willing to blind test (they were all just willing to say "it's obvious"). How many people here running the lagfix, have run any kind of blind test, or test with predictable steps to demonstrate a difference? Please, raise your hand people, because there is a huge difference between "it seems lag is gone" and "Lag is verified gone".
Quadrant is a guide, it doesn't test interactivity, and it only tests a few operations. It's similar to how a browser can pass ACID3, but have terrible compliance to new standards. Because people became so convinced of benchmarks accuracy, Nvidia and ATI started optimising for benchmarks.
Normal SSD's are also blazingly fast on benchmarks initially, but if they don't have TRIM, their performance drops significantly. That's another example of something benchmarks don't accurately test (because the testing is incomplete).
Use it to get a general idea of how the phone performs (although, specs might be more useful in some cases), but you probably need profiling and a predictable list of steps to diagnose the lag exactly. Run benchmarks which test according to the types of applications you are planning to run (if you play 3D games for instance, use a 3D game benchmark). But don't rely on them exclusively to tell you how well a device performs, because only running the applications and testing them yourselves can tell you.

But do you really think that one-click-lagix or whatever is that much faster than mimocan's one (like 2800 vs 1800)? I don't think so...

Predictable steps to demonstrate a difference:
1. Use 2 SGS, firmware of your choice
2. One with, say, 1 Click Lag Fix - the other one stock
3. Now for the test, perform simultaneously:
3.1. Open Market and go to "Downloads", update an app, close.
3.2. Open Contacts, quickly switch to favourites, dial Number. Drop call. Exit.
3.3. Open Messaging, conversation of your choice, quickly switch the writing language, write, send, exit.
3.4. bla bla goanforeva
Now if you don't notice an improvement there and in many other cases you most certainly have done something wrong.
If you are saying people are just being placebo-ed you are implying that everybody else besides you is unable to tell a real difference. Think about it, maybe it's the other way around.
When I got my device it came with the Asian JG4 firmware I think and I used it for 48hrs as a point of reference for this so called "lag" I updated my firmware to the latest we have and found zero difference in terms of performance ( same 2 day usage ) decided to flash my device with JM5 and used it w/o a lag fix for 2 days, notice a very slight improvment on how fast the inbox/contacts can open and then did a fresh flash with lagfix 2.x installed I didnt NOT notice any performance difference but I am always open and welcome to any lagfix that is stable,safe and fast ( in that order ) right now I have JG8 installed w/o lag fix and its very snappy, I still want to install a lag fix for this even if i dont see/feel any performance difference at all.. thats just me.. Now im wondering w/c lag fix is the most stable and safe.. stability/safty > speed
EDIT:
Also I believe it could be possible that certain versions of lagfixes work better with certain versions of firmware also, its all about getting the perfect combination.. altho my question still stands on w/c is the safest lagfix heheheh
Well actually i gave up on benchmarks.
To me the whole user experience is more important. If apps open instantly and the phone runs smooth then it's fine with me. I did notice some firmwares are better then other ones.
Right now i'm running JM1 (rev 3) with CFLagFix1.80 installed which makes the phone very stable and running smoothly so right now i'll stick to this firmware until a proper GPS fix is released or until Froyo is released.

Lol I think you didn't understand my question... I'm sure that these lag fixes all work, no doubt about that. But which of them is faster? For that i can't rely on quadrant i'm sure...
Hi Forum, I hope this is the right forum to pose this question and to discuss the topic
ok the question:
Am I the only one who is bugged by the fact that, to close most applications in WP (wheter it is active or in background), we have to tap the "Back" button as many times as the number of pages? here are some pics so you can understand my point xD
http://img571.imageshack.us/img571/9092/31238975.png
http://img571.imageshack.us/img571/5176/30856883.png
http://img407.imageshack.us/img407/4329/28248076.png
As you can see from the last 2 pics, in this case, the user has to click backwards at least 2 times in order to close the application.
Wouldn't it be better to have a small icon in order to close the application completly?
Something like:
http://img803.imageshack.us/img803/2318/50922462.png
So! What are your opinions?
Is there something like this already?
Do you think that a mod or something could help out with this "problem"?
Do you think WP8 has a feature/solution for this?
Or is it just something personal xD ?
There is no other way but there is also no need.
The background applications do not consume CPU like they do on android, and if memory is needed, the OS simply closes them down.

So it would seem and though they are thinking about the whole thing wrong this mind set cant be ignored even if it is wrong. A lot of people come from the Android ios world of background tasks killing battery life and performance.
Maybe if they have a close app in the tiles screen to address these concerns. Even if you know something is not needed if the customer thinks (even wrongly) that it is then you are going to look like your product is not as good even though you know as an expert that it is. I get this all the time in my job and that's why I use the mother test, I send an idea to my mother and if she gets it then I know its good if not I rework it.
Idk about IOS but in android it is a mistake to close down applications in most cases.
In fact, many people don't know that pressing the close button does not actually close the app, but move it to cached processes. You then have to kill it again in there to finish the job.
Anyway, many apps are persistent in android. Killing them will only make the system want to restore them again, thus eating more CPU than they would have if they were running.
On the other hand, they do represent a resource hug when not closed.
SO on this aspect, android does have a big problem with its multitasking and this is the main reason why android is such a resource hog, and requires quad core CPUs and loads of RAM to get the job done right. And google isn't doing much about this, in fact they continue with the resource waist, which will inevitably put a cap on how much android can do.
As for Windows Phone, it is fairly easy to restore the application to its stage before closing it down. People just don't know about that (and neither most of the developers).
Android phone and WP7 phone have almost same battery life, however, android has true multitasking but not in WP7, which means WP7 actually comsume more power. From my point of view, if I want to close an app, I don't want to see it appear in the backgroud. This give the chance to run it unexpectedly if I accidently tap it in multitask screen
The battery life is a non-issue with multitasking.
It doesn't matter how many apps are running, the CPU uses the same amount of power.
On the other hand, android is much slower than windows phone, which is because the android multitasking is a resource hog that is not really needed.
Remember we are on phones after all, not super computer.
If there is not much to do CPUs clock down or go to sleep completely for some time therefore reducing power consumption. On Multi-Cores in low utilization cores are sometimes completely powered down. So if only one program is running and it's not a game needing the CPUs full power it's highly likely that the CPU will use much less power.
If instead I have several Apps running in the background then I have a higher CPU utilization that doesn't really help me with what I'm currently doing (with the foreground app). That is why background Apps are frozen on iOS and WP unless they do something specifically allowed (so nothing happens in the background that's not really necessary).

One could argue your point. I'll agree that WP7 runs great with low spec phones, but the new Android devices are simply faster. Compared to my mom's SGIII, my Arrive is painfully slow at loading apps and websites. Also, the SGIII lasts considerably longer than my Arrive, which shows that poor battery life on android devices are a thing of the past*.
Dont get me wrong, I want the WP platform to succeed(I think its a great OS), but it still has a long way to go; and limiting the max spec of WP8 to barely beyond current generation tech really sets the bar low.
*yes, I'm aware of the SGIII's battery size. Still, I can easily get two days out of it, vs my Arrive lasting 1-1.5 days

The core clock is a non-issue on android.
You will never be able to stop all applications, some of them (most of them) return minutes latter, because the OS is programmed to restore them. Many poorly programed applications behave like system applications and they keep running all the time.Standards are pretty low in Android. Which is why things like app closers, scheduled task managers and other stuff like that exist.

Compare the specs of the new android phones. Compare their prices as well.
SGIII literally has 4 times the processing power of the highest end WP7.5 devices currently on the market, and performance is comparable between the two. WP is an awesome platform. Android is not even close.

The US spec SGIII uses the Krait processor, not the quad core. While it would be comparing apples to oranges, in a sense, I still stand by my case: with the proper hardware, the Android platform can be just as effective.
My stance stems from the arguement that WP7 is a better OS because it runs very well on basic hardware. This claim drove me nuts because M$ was so bent on proving that point, that flagship devices ran on half the hardware Android phones of that generation were currently utilizing.
Comparatively, it's the difference between running XP and Vista on legacy hardware vs current hardware.. People were knocking Vista because it was a resource hog and ran like crap on most computers; on the other hand, it runs better than XP machines when kitted out with newer hardware. One OS runs very well on less specs, but plateus very quickly, where the other platform requires more resources, but scales better when properly complemented.
In essence, WP7 is XP
I hope you arent portraying me as an Android fanboy, because I'm not; I'm just being brutally honest here. I really want to see WP8 succeed where WP7 fell flat, but seeing MS fitting compatibility specs of WP8 devices with fairly short outlook leaves me feeling uneasy.
BTW: I've been using Microsoft PDA's and smartphones since 2004, and have used both android and iOS devices for about six months out of those eight years. Juust so you know where I come from =)
Actually the OS does quite often not have that much influence on actual application performance. The big criticism of Android has always been that it tended to perform crappy (force closes, stutters) even on high end hardware. Some of that has to do with process priorization, some with missing hardware acceleration, etc. Google is working on that with every new release.
Especially in games one noticed that the devices lacked in real power on the hardware side. Another problematic decission was the use of the panorama controls. Those are side-scrolling controls with very often vertical endless scrollers inside them. This is actually rather complex to render and I would guess is responsible for most of the badly performing apps around. This is further complicated by the fact that non-developers rarely can grasp intuitively the actual computational cost associated with certain visuals (hence the often cited: WPs minimalist design is easier to compute then Android/iOSs more complex UI elements).
Microsoft was aiming at the possibility to produce cheaper devices. There were citations that the average WP7.5 device only cost $200 to produce. That strategy obviously didn't work out so well. Maybe due to the fact that the devices still were sold at flagship prices.

That'sbut back to the topic: the fact is that wheter it consumes cpu or not, the average user would like it to be easier to "kill" an application without pressing the "GoBack" button multiple times. That's the main argument. Leave all the CPU, and Core Processor argument behind , cuz WP os deals beautifully with this...
Hello,
I got the Tab S2 8 inch or WiFi only model - SM-T710 on launch day.
I was really excited for this since I was upgrading from an iPad 4, which felt slow.
However, I was disappointed with many things :
1. Most Apps are not tablet optimized.
2. Asphalt 8 tends to lag, although I never noticed this with my iPad.
3. Only 1GB of the 3GB RAM seems to be available most of the time.
4. The play store won't let me access the US play store from outside the US.
5. Part of the Tablet feels hot after light usage.
Can rooting my device help with the above mentioned problems?
How can I fix these problems? Normally I would have done these myself but since I'm completely new to Android I wanted to ask. I've been using iOS since 5 years and I've never had any problems like these. I'm also a fan of iOS jailbreak, tweaks, etc..
One more doubt : Is there a chance that the Tab S2 will get the Android M update?
Thanks,
Trix

1. No issues on my s1
2. Can't help with that, don't play games
3. Perfectly normal on an Android device, Android doesn't waste ram, it uses it to make your device faster.
4. You probably need to load the firmware for your region.
5. Same as the s1

1. Unfortunately, that is going to be a common thing with Android. Google built scalable interface based off the resolution, which makes apps run on tablets. As opposed to the iPad, there isn't a scalable interface feature but instead it uses upscaling, which makes apps very large and blurry.
In addition to that, Apple forces the default settings of the app store search to only show iPad only apps. This means, if you didn't update your app to support tablet interfaces manually, you wouldn't show up on the default search. This pretty much *forced* all of the developers to update their apps, if they wanted it to be seen of course.
But, since Android scales all of this natively the developers are lazy and simply do not update their apps for tablet interfaces as much as iOS.
2. The Tab S2 is a very powerful tablet, but if you're comparing it to the Ipad Air 2 there's going to be no comparison on how the iPad is much stronger. The processer on the iPad is more powerful than some computers people have at home. However, Android really is not a gaming platform, it is more of a productivity platform. There are way more games on iOS than Android, so if you're into gaming (on mobile) stick with iOS. Both platforms have hardware that is compeltely overkill than what most of the gaming apps actually require.
3. That honestly is no different than the iPAD, the amount of memory free should not be a concern unless apps are closing more often than you would like. Keep in mind that iOS struggles with memory as well, you can browse the internet and minimize the app and come back and it will reload the entire page, losing the spot you were scrolled to. On Android, it actually remembers the last spot you were at, simply because it has better memory management.
Keep in mind tablets are solid state, with incredibly fast read and write speeds. Ram can actually become irrelvant, because it can simply page the memory to the solid state drive and it would be effectively the same speed as real ram; you could actually get away with running with 1GB of ram easily. It's just that there is a limited amount of read and writes to a solid state drive, so they still use dedicated RAM to extend the lifespan since it is cheaper than solid state drives in general.
4. You can use a VPN to bypass that restriction.
5. Both the Ipad and S2 will got hot if you try to game on it, these devices don't even have fans in them so I don't know what you are expecting.
With that being said, I much prefer Android over IOS. When I use my iPAD, I've pretty much given up searching for an app because it simply did not exist with such restricted permissions on the iOS platform. With Android, I can customize my tablet to my liking, and I really like the keyboard support on it; it is much better than Apple in that regard.
I own both tablets and I use the Android far more, both have their cons and advantages. But for me, I don't like mobile games, I find them too simple. Thats why I love Android because I can emulate all consoles up to PSP/DS ERA.

The read/write speeds of ss flash memory is nowhere near as fast as ram.
The Tab s and s2 both have very fast ram.
If manufacturers relied on flash memory for caching and system read/writes with today's fast cpu's the system would bottle neck and crawl.
Fast cpu's need much faster memory to keep up and run smoothly.
Run some benchmarks and you will see the difference.

Yes, there is no question that RAM is much faster, but if you're comparing it to normal usage most people wouldn't see the difference. The Surface Pro 3 64GB edition runs off 2GB of RAM and constantly runs at 90% peak memory and ironically performs just as fast as the 4GB version simply because the solid state has such a high read and write speed.
To a certain extent, all tablets page to the harddrive. As far as I know, there aren't many flagship android models that feature like huge amounts of super speed ram.
When you're comparing it to "much faster", say if you are travelling 500mph and you could go 1200mph, but you already get to your destination in less than a second so for the average user, they probably wouldn't even notice the difference.
I suggest you do more research on it.

The average user is not going to notice their device is faster if the device is perfectly capable of loading basic tasks such as websites at reasonable speeds.

1) Yup that is android sadly there. Though more are coming out with tablet versions of the software... FINALLY!
2) I haven't noticed that myself on the device as I do play that game as well
3) As long as it free's it up, there is no issues with having ram used. It will dump memory as needed if apps require more. Typically most apps don't require that much ram so no issues.
4) Thats just a country/region issue with the device ID. If rooted you can fix it at least. I travel and when outside the US the store is still US to me.
5) Most devices are like this. Gaming will make it hotter as well, but that goes for Android to Apple as well. Now, this device is cooler than previous ones I've had under heavy gaming and light usage gets a little warm.
As for the new OS, we can assume so, but since its a little ways off it might take time still for it to "Officially" come to the tablets.
I just bought mine yesterday and one feature under the settings was missing... there's no user under the device the options only are:
-sounds and notif
-display
-motion and gestures
-applications
there is no user. also in the notification panel there is no manage user.. can somebody help me plsss.. thanks in advance!
Tab S2 problem
Hey guys, hopefully someone here can point me in the right direction. Looks like i got screwed with my Tab S2. I bought a 9.7" cellular version from someone on Kijiji (Equivalent to Craigslist in Canada) and it was working just fine. I installed some apps and was just playing around with it. About two days later it started freezing and restarting when i would play a game or watch a video. Since then it has gotten progressively worse. I boot it up and 30 seconds to a minute later it turns off on its own. I thought it may be a software issue so i did a hard reset but the problem still persists. I took it into a Samsung repair center and they said that it is a pre-production model (IMEI is 00000000000000) and they cannot help. Any ideas what i can do to repair it. I just hate the idea of having a $400 paper weight.

1. random hanging 3x-10x/day depends on usage.
problem: hanging that leads to black display screen
solution: soft reset -> press the power button+volume down for atleast 10secs
or until boot up screen shows up.
1a. random hanging usually happens
-when downloading or opening something in the Playstore.
-exploring the settings of the gadget.
NOTE: I noticed that it happens frequently when clicking/using apps
that is related to its Internal Memory.(eg. problem#2)
2. Calculating the Size of the Applications
problem 1: it keeps saying computing even after 30mins of leaving the screen.
solution: unmount sd card>remove sd card>insert sd card.
problem 2: can't clear cache of an application.
solution: need to restart the gadget for it to take effect.
3. Auto Restart then it didn't boot up properly. It only stayed in Samsung Screen.
CONCLUSION: it's not normal to have these kind of problems 3gb of RAM,32gb of internal memory, up to date updates.
: very few widgets are activated, very few downloaded apps installed.
: strongly convinced that the cause of problem is its hardware specifically its internal memory.
it's reported that on a test on the 3T it was discovered that OnePlus now targets benchmark apps by name so it scores higher , that's not good to be honest, the device is solid and rational users don't need this, I admit it's nice to test and see your device high up the ranking but only when it's done organically ,
that said this appears to only be introduced on the N Roms (including betas)!

im on oneplus 3 so i dont really care.
Still a great phone..
Lots of phones cheat on benchmarks. Not really new

it's a software thing not a device thing, the N rom has the "feature" so it affects both 3 and 3T...
not saying the phone is bad, i love, i'm saying it's not needed... some companies did so in the past, but it's now over so why do it, the OnePlus brand in general wasn't built on Benchmarks.

403 error when i click that link
Yeah just read the article I was annoyed that oneplus would be involved In something so stupid when this phone is an awesome device, I don't see what they would have achieved from even doing that.
People do this all the time themselves. It's the same as "intelligent" profiles that switch depending on application and load.
If this happens for games then whats the big deal? People say it should work for all apps but i dont want my cpu going through battery just because I have my clock app open. Sure there should be a setting for it but still they see this app as a power hungry app so they give it juice, any other app which doesn't need this power just doesn't need it.

The difference in performance is very small with these cheating tweaks. Personally I don't really care about the cheating at all, I love this phone and it's features and performance.
I haven't installed a benchmark app in years and not about to do it now. I'm only interested in real world performance.
This is one reason why people don't trust Benchmark scores.
People put way too much importance on benchmarks anyway... They are largely meaningless, but you see dozens of threads of people trying to tweak kernels and all sorts of stuff, to get an arbitrary score in a meaningless app because they think it gives them bragging rights.
Benchmarks are for kids. Real world results are for adults.
Check out op's explanation on that
Seriously? What about i-creap? How can that i-**** could be nr.1 in benchmark?!?
If our devices are effectively overclocking to achieve better benchmarks, sooner or later the OS will have to turned down the SoC as the temperatures will get too high if the benchmark is ran over and over again.
If you want to know the true benchmark of your OP3, I suggest running it over and over.
is this thread necessary?
lel for this type of discussion.
Hello
I have upgraded my Tab S7 to Tab S8. And I have expected new device be much faster and smoother, but what I found that games are really lagging! It was perfectly smooth on S7 but not on S8. Game mode does not help much. I do not play a log of games on this tablet as I used it mostly for developement, but I do play Harry Potter Puzzle and Spells and this game lags pretty bad on S8.
What can be done to fix it or should I wait for Samsung to release update? I do know about Samsung's throttling on S8 devices but I never expect it to be that bad.
And in addition (don't want to open another thread) it seems that S8 has more aggressive memory settings because it unloads apps from memory over time. Which never happened on S7. S8 has more memory and I think it should keep more opened apps, not reloading them. And yes, settings in developer section (do not keep activities) is not enabled

This has to do to android 12, s7 was only on android 11, but also is on 12 now. So then it automatically puts apps into deep sleep. You can remove that under battery settings area and remove apps from deep sleep mode.
About lagging it might be new game mode from samsung since apparently samsung did on purpose limit hardware but added a settings into app that let's you gain more performance in games. Should be in game engine or w.e name is and then settings and then Labs and enable experimental feature there that should boost performance and stop limit the hardware for game.
When I replaces S7 it was already on Android 12 but I never observed such behavior. Anyway, I have put game into never sleep list. As about lags, unfortunately I found no options for that

I was noticing this particular with emulation since I don't play many native android games. When playing Sonic Colors at native res on my Tab S7+, it would almost never go below 30fps in level, and almost never below 60fps in the hub and menus. However, when I tried doing the same on the S8+, I had a bunch of stuttering and performance issues no matter what version of dolphin I used. There was a workaround to this (at least for me). These issues only happened when I restored my data to my new S8+ with Smart Switch, but when I just put all my data and stuff on there manually, the issues seemingly stopped happening. The only game I throttle in is Fortnite, which didn't have the 90fps option even though the S7+ did. The game still didn't feel much different before and after the throttle, still pretty consistent framerates overall.
Edit: Just fixing typos.

Did you used cloud backup or restored through cable or it's the same thing? I have similar problem, but with benchmark results. My device can't get even average model score in 3DMark (about 2 to 8%). Geekbench scores are worse than snapdragon 865 devices. I don't know what's going on. I already tried to reflash stock rom with odin, but that didn't help. Hopefully not using cloud backup will help.

I initially restored with a cable, but once I started getting shawty performance, I made a backup on my sd card and restored it from there with Smart Switch. I never used cloud backup since that takes a lot of time for me. After getting suboptimal results with both, I just bit the bullet and slowly started adding everything and getting it to how it was on my old devices. Only then did I get getting substatiall better results. Now I can run a lot of Wii/GC/3DS/PS2 games at 1.5x, 2x, and sometimes even 3x without getting throttled. Not sure why using smart switch tanked my performance, but all I know is that it's not tanking now.
Thats interesting. Because I also moved data using cable. I do not know how good is cloud since I never did it before (only on Apple devices).
I might try to fully format tablet and test it again.
Will provide more information later

I tried formatting few days ago, and that didn't help. At least for me this problem is not related to Smart Switch. Do you also have bad benchmark scores? I understand that benchmarks are not very good indicator of performance (especially due to GOS), but I expect to have at least average SD8gen1 performance, not the level of SD855.
Did reset to factory settings. It is much better at least for now. Benchmark - tested only Geekbench 5. Result the same
Hi.. I'm experiencing the same problem here.. any updates regarding this problem? My geekbench score can't even surpass an exynos 2100.. it only achieve around 700ish on single core.. the first time I notice this is when I tried playing granturismo with aethersx2.. and it can't even handle the 1x reso.. hhhh.. really frustrated here.. please kindly share any clues regarding this topic thanks in advance.. sorry not a native English speaker
I had same problem, but, i solved using this:
ADB AppControl 1.7.5
(disable all game service (i'm not remember how many)). For me it's work great
--edit
i disabled bixdy and others apps too
First.. thank you for the answer! Might try it out later..
So it's like disabling the "GOS" right? Is it different from the "alternate game performance" option in game booster? They said it's the "official" way to disable the GOS.. but yeah I didn't find any difference after enabling that option though... Hmm..
Hmm...also.. What makes me wonder is.. I saw some reviewers review this device without any tweaking needed and they could achieve a 8gen1'ish results in benchmarks.. and also if you know ETA prime on YouTube.. he reviewed a tab s8 ultra and is able to run a granturismo 4 with aethersx2 (ps2 emulator) in 3x reso in default settings with no problems... I know it's a different device but it's supposed to have a same Chip right?
All of this things makes me frustrated because it was not what i expected from a 8gen1 device.. moreover I saw a sd870 device could run the granturismo 4 in the same settings with no problems.. it really broke my heart..
The issue mainly lies in the SOC.
Even though, SD8 Gen 1 has a much higher peak performance, especially in GPU, it can't sustain that performance due to excesive power consumption which results in thermal throttling.
GOS is another thing that affects the whole experience, it's limiting the performance of the device.

Yeah.. I think this is mainly what cause the problem.. The 8gen1 itself..
a quick update regarding this from me..
I've done some re-test in benchmark and real game perfomance but this time im doing it in a well conditioned (cooled) room..
previously I was doing the test and gaming and in a room without any Air Conditioner and I lived in a tropical country which is really hot and humid...
the benchmark results (3d wildlife) came out Nice in a well cooled room, It scores what most of Tab S8 would score and the real life perfomance (PS2 emulator) is also improved..
it manages to handle GranTurismo 4 in aethersx2 with 3x reso on safe setting quite well..
the CPU temperature is well managed in around 35'ish Celcius compared to 45'ish when not using any air conditioner...

CPU temperature 35 Celsius degrees? Are you talking about an ABSOLUTE idle? Because even if you would put a bag of ice on the TAB it wouldn't sit that low under usage. Even small loads will put the CPU around 50-60 Celsius degrees. Under heavy load up to 85-90 till the thermal throttle hits in.
Also, that ONE wildlife mark test doesn't do much. The idea is stability, better known as SUSTAINED performance, and that's where SD8 Gen 1 ****s itself. Try running a Wildlife standard stress test (20-minute loop) and post the screenshot, you'll see what I mean.

I only saw the perf-z indicator from samsung though.. so yeah.. i know i might just straight up wrong about this I just straight saying what I saw.. and honestly I'm not an expert in this.. just a mere consumer..
Yeah I got you.. it goes downhill even after the first one.. what I'm trying to say was that I never reach that score before in warm room so yeah it's mainly the CPU problem..
What mainly being my concern before was I'm scared that I got scammed with a fake/unoriginal/refurbished tab s8.....
Harry Potter plays fluently on Tab S8 Plus here.
I have sent my S8 to my mom and bought S8 plus. Did not restore, set it up from scratch. No lagging in games, including HP. So, it could be related to thermal soliton in S8 plus as it is bigger

Yes you have to run 4 adb Commands that also disables game booster and game launcher then GOS will stay disabled even after restart. I've done this and turn ram plus off. I also disabled or put into deep sleep all of the bs apps. I also went to advance features and turned off all of everything causes I don't use the s-pen so no need for air actions and stuff to be on. If you want the ADB commands let me know.
