[Q]Smooth the edges

Ok so I love android and all of it's openness and mods. I like to modify all electronics that I have. But the only problem I have with it is that it isn't smooth. I have had an iPhone in the past and it was smooth. It just confuses me how 1ghz can lag on a mobile os. I guess this rant is to ask how do I smooth the edges. I've tried many roms and some were better than others. One major thing I want is when I unlock it, when I slide homescreen, and when I open the app drawer to be smooth. Any ideas settings roms?

Read through a lot of threads, and understand that there isn't what you're looking for. You might try MIUI, people report it as smooth - never tried it personally. Also, for launcher use LauncherPro, it's smooth.
About the gigahertz stuff: CPU speed doesn't matter as much as SW does. And there is no "smoothness support" yet.
Android isn't smooth. It's powerful, though. Personally, I like the trade off.

delete all your apps, turn off all services, and it will run just like the iphone. kill every app after you use it. - that's what the iphone does.

You can tweak the internal task killer to speed up your phone. It takes some work and testing. This thread has the directions and explanations.

This has been useless since Froyo. As I once researched and posted, Froyo kills the processes much earlier than Eclair (OOM=12 instead of 16) and considering the amount of memory on Nexus - you never get anywhere below 100MB free unless you run a super-heavy app, and those never stay in background.
Now these tweaks don't do a thing.

does power mean smoothness? I just don't get the concept of having a fast processor and not being smooth. I mean it is almost the same speed as my netbook... on a phone. It seems like that should be smooth. Maybe I'm asking for to much. But another thing I have seen videos of people on cyanogen and it is running smoothly with a live wallpaper. I have never got cyanogen to run smoothly for me even with a still wallpaper. Is there some magical setting everyone but me knows about?

Power = ability to do things. Not CPU power, OS power.
Smoothness = frame rate of transitions between screens in UI. By most part, it's a result of heavy GPU utilization (which Android doesn't do stock) and programming that puts graphics as top priority (which isn't the case with Android). When CPU is made busy making beautiful graphics, it makes beautiful graphics. When it's not the main concern - it makes what it makes.
Again, you seem to be complaining about the launcher - otherwise you wouldn't bring this live wallpaper thing. So go download LauncherPro.

Folks go on about miui being smooth but personally I found it quite choppy at times, and this was most evident using the miui default launcher and comparing to say an iPhone 4, it looks very stuttery. Its better with launcherpro, but then you've lost half the reason for using it.
I am using cm6 and a theme (minimal matte fwiw ) and its very smooth and nice looking (and believe me I am very sensitive to, and loathe slow performance on a latest Gen phone).
Best compromise I've found yet on android.

I use the latest CM6 nightlies with Launcher Pro Plus and have a lot of widgets on my homescreen, smooth as butter.
I do remember the homescreen being a bit choppy when I ran 2.1 on my N1 though...

Have you messed with the performance settings? I hear that switching the performance setting to 24 instead of 34 helps. I'm not on cyanogen right now so I don't remember the exact setting but it is cyan settings then performance.

Truth of the matter is, is that Android running as SMOOTH as an iPhone would be difficult, simply because the IOS operating system doesnt allow any applications to run in the background. Android has TONS of apps that run in the background, and its still smooth as hell if your running the right ROM.
In all honestly, as much as I LOVE enomther and cyan ROMS, MIUI is hands down the smoothest and fastest ROM I have ever used. Give it a shot. I promise that if you can get past the iPhonish look, you will LOVE the speed and fluidness of the ROM. I cant recommend it enough.

I have used the miui roms and they are awesome. But honestly I just feel like a sell out while running them.

The reason why even iPhone 3G's can feel "smoother" than Android phones at most times: hardware acceleration.
Ever since the 2G they've had a dedicated GPU which was used to its fullest in basic UI interactions. We see phones like the SGS with freak GPUs but Android doesn't allow full use of them.
Phandroid made that article on a supposed "Gingerbread" leak. They claim it will introduce hardware acceleration. Hopefully thats true and we'll never hear complaints about a laggy UI again!

Yup, most of the smoothness complaints is just hardware acceleration complaints. After gingerbread if it has hardware acceleration, we won't hear the laggy UI issue, we'll just hear the bandwagon "Fragmentation!"

Will a custom kernel like Franco solve lag issues on stock 4.2.1?

Well I'm not really experiencing a lot of lag, but it's not really smooth, even my old LG Optimus 2X running CM10 is smoother than my Nexus when scrolling through menus.
My nexus really lags a lot when scrolling through documents, and on the app drawer, especially in the widgets tab. Some games like NFS and beach buggy blitz doesn't run smoothy too.
So will a custom kernel fix everything? I don't really want to install custom ROMs.. I like how stock feel and I'm kinda sick of customizing like my LG.

Did you try disabling Background sync in Google Currents?
That should help a bit.

I cleared cache, and disabled the app altogether. Still doesn't help.

Coming from stock 4.2.1 switching to dirty aokp with Franko kernel I can say I don't really notice a difference in lag. 4.2.1 never lagged for me before and I can't understand what people are talking about. Maybe it's because I never experienced the previous versions before...

You can install Beach Buggy Blitz from Market. It is free game with great graphics. Then you can see lags, with gaming. And there is no solution for this.

Lag with a specific game is not general system lag...
All of these "lag" threads all go the same place; every random direction. No coherent information is ever formed..
I too would like to figure out how to get rid of the random lags after waking the device, during IO, just random other times while using the device etc.. I'll try a kernel, maybe a custom ROM at some point, maybe I've waited too long, but I've been using the stock rooted ROM. First device I kept the stock ROM on since I got my Nexus One, at least for a while

4.2.1 here with 0 lag. Currents background data WAS enabled, but I just shut it off. Thanks for the tip.

What kind of lag? While doing what? Without a proper description don't expect too much help.

Like everyone has said it is hard to tell without more information but generally custom kernels do provide better performance overall and therefor would probably be best for covering all the bases.

Like all machines aren't created equal, I don't seem to be experiencing any kind of lag on my device, as it is buttery smooth even in stock rom. I guess your device maybe running hot?

So I installed Franco on it, and lo and behold, the device got a lot more smoother, still running stock ROM.
But the battery is taking a plunge!! No idea why. Perhaps a re charge will solve problems.

It helps quite a bit but still nowhere near the smoothness of 4.1.2. Recent Apps button still takes a while to load for example.

My stock 4.2.1 is quite smooth, even better than a lot of custom roms. A different kernel improves it a bit, but not by much.

i lag too. I think it is because of lack of ram. I always have to manually close out all apps to make things smooth again.(hulu and netflix use alot of ram)

Is Project Butter effective on the Galaxy Note?

Since Project Butter was announced as groundbreaking for Android devices, it would be good to know what the community thinks about it as the official JB ROMs have launched.
Please provide your input as a casual user and your day-to-day experience, and also as a more techie user or a developer.
The intent is to provide Samsung, if they still lurk on XDA, feedback on how they can improve future development to make Android really smooth, even though the UI is not treated with priority, as it is on iOS.
As far as I am concerned, I didn't notice any difference from ICS to JB on a stock ROM; essentially, Project Butter doesn't exist for my device. The device still stutters where it did on ICS.

I would agree with your assessment. I think that the stock JB is very stable, however there is no noticeable difference in speed compared with, say, LRQ.
When I press "contacts" or "phone" button, there is still a lag. My understanding of project butter (rightly or wrongly) was that these kind of lags are supposed to be almost eliminated.
Interestingly, when my wife's galaxy S was running slimbean 3.0, it was close to what I expected "project butter" to deliver. However I reverted her SGS back to ICS due to stability issues.
edit- I'm on LM5
edit 2 - Interesting that 90 people have viewed this thread so far, and nobody has disagreed with Incisivekeith's review. Perhaps we can conclude that "project butter" is not included in LSZ or LM5.

To my mind, Project Butter means an entirely GPU accelerated UI. That is what explain this "buttery" feeling when you drag down the notification bar, when you scroll in the browser, etc..
It is certainly activated in our JB roms, because if it was not the case, the rom would be much more laggier, and touch wiz would be the pain it has ever been since the Galaxy S.
However, I'm sure our PB is a far less efficient one than used in the nexii phones. You can easily tell, there are still some lag in the appearance of the notification bar (when opening an app, laoding something..), and the whole feeling is absolutely not like any Apple device (that I despise, of course ).
I have none of the technical skills to give a more detailed answer, but I remain amazed by the fact our devices are not free of any lag, in spite of their double core, big GPU, 1gb RAM etc...

To realize project butter you need a high speed camera. If you running heavily skinned OS has TW you will tend to see some lags. Remember Our note is almost year and half old....

But we don't have the choice, i don't think any android AOSP/AOKP rom includes project butter, am I wrong ? These roms feel more laggy than any touchwiz rom, though they also feel lighter. And it's a shame (I blame samsung) because they are innovative and functionnal.

AW: Is Project Butter effective on the Galaxy Note?
As far as I understand, pb is not an acceleration for the hole system, but an acceleration for gui: no micro-lags in launcher, scrolling in Browser and apps. And it does really better, than ics for me. Just compare xda app on both systems and you'll understand what I mean

I tend to disagree on the part which states that these AOSP/AOKP ROMs feel more laggy than TW ROMs. As of today, I run Asylum ROM 25/02 which includes major improvements concerning the overall UI experience. It is snappy and smooth. I do explicitly avoid the term "buttery smooth" as it is misleading.
They are not finished products, that's for sure-but being heavily developed. :thumbup:
Any TW ROM running 4.1.2 won't be "buttery smooth" neither, whereas the leaked 4.2.1 ROM for the S3 already showed improvement and thus where helpful to update the Mali blobs for CM10.1, which are successfully implemented. They do work nicely!
If permitted to ask: when did you last try out an AOSP/CM ROM?
Side note: if you blame Samsung, you're always right! I fully agree.

I'd like to step in here, and this is entirely wrong: Project Butter was not included in jb for viewing in high speed cameras: it was mainly to reduce lag and stutteriness in Android to make the experience amazing for common, general public. Not for professional photographers.
Personally, when my one v is over clocked to 1.5 GHz and above ( and using a jelly bean ROM), the effect is mind blowing. I'd say the device comes near smooth as an iOS device, if not smoother. There are absolutely no lags and waits, and the device performs like a breeze.
Have you ever used a nexus device? That's the best implementation of a device blessed with project butter combined with the blessing of great developers of Google. I have not seen a nexus 4 lag ever. EVER.
Personally, I don't get what's it with galaxy note. I can't understand what's wrong with it to lag so much, I mean, sometimes it lags more than my one v which is a 1ghz single core processor ( I'm not talking about over clocking here).

I totally agree with you, and the fact that an incredible amount of great work is put in AOSP roms remains undeniable. As I said, I blame Samsung, and my respect for developers is unbounded.
My last try was for beerbong's paranoid android v2.99, and I've tried almost any rom in the original dev section. Still, it's been a long time since I have tried, so i'll have a look ! Of course, there are other things that make me stick to stock, SPen integration mostly (looks like there is still no way to use palm rejection in CM roms).
Anyway, I'm glad to see JB leaks help CM developers, I thought the only workaround required kernel sources.
@soham_sss
I see I'm not the only one wondering what could prevent the note from being smooth...

For me, JB is very smooth. Don't forget, that our GNote has just that little Mali GPU which has to drive this huge 1280x800px (Macbooks of 2011 have this resolution ) screen. Based on that fact, JB is buttery smooth.
I suggest to set all animation times in the developer options of your phone to 0.5 (don't forget to reboot, to get the new speeds everywhere in the OS). It makes the Note feel much quicker and more responsive.
When you are there, also try "Force GPU rendering". Every app compiled with the 2.3 SDK has the GPU rendering flag set to off, this option forces it on. I haven't found any apps that don't like this setting and crash. Also, when you google for this, you won't find any apps neither that refuse to work.
I'm very happy with JB. It's smooth and the CPU doesn't have to render anything anymore. Nice!

As I'm thorough, I tried Asylum ROM, as advised. :silly: One thing immediately stroke me : the notification bar is not smooth. It just isn't, there's a discomfort that should not be as if it was still CPU run. And I don't think I'm picky, it's a raw feeling. The rest of the rom is, indeed, pretty snappy (the browser appear much much lighter), but I really need this element of my UI to be impeccable as it come to smoothness, just like the home screens transitions.

+1 couldnt agree more.
Ive always had nit picks with my android devices (mainly samsung, some HTC's in the past) and have always experienced some sort of lag, with stock and custom ROMs.
But, correct me if im wrong, I believe this is down to the overlay put on by these companies, they cram the devices with ridiculous amounts of bloatware and eye candy and I feel that has an effect on the overall smoothness.
Ive yet to own a pure AOSP device (such as the nexus's) but i cant recall many people complaining about them.
But I prefer the looks of TW / Sense over AOSP (and ive tried lots of AOSP ROMs) so I accept that bit of lag for the overall look and functionality of things.

Oops. I will change that. Nevertheless: That GPU just isn't the fastest anymore.
And that AOSP is faster, is just normal when you don't unbloat your phone. It's the same with every other Android phone out there. Also AOSP doesn't offer multiwindow, I bet many people aren't really aware of the technical difficulties this brings with it. And therefore this phone is very smooth.
Also try tinkering with the build.prop a little.
windowsmgr.max_events_per_sec
persist.sys.use_dithering
persist.sys.use_16bpp_alpha
can help a lot with the "lag".
But I don't have any lag, so I'm not changing anything. Another thing to maybe consider: Do you have a corrupt install?

The point of this thread is to discuss whether Project Butter is effective on the Note or not, WITHOUT any modifications.
4.1.2 JB LSZ Ultimate 5.2 ROM, KSO Modem, Phil's LSZ kernel, Carrier: AT&T (US)

It isn't since AFAIK Samsung doesn't release source code for Exynos.

If those on a TW JB ROM could download and install "Epic Citadel"(preferred via WiFi as it is a 150mb package) and play the demo. I bet it won't get beyond the 40fps in high quality..
I didn't advise to install Asylum and don't quite get the point of the notification bar. As long as Samsung fails to deliver "proper+sources" we won't get the real "butter" experience.
Apparently the leaked S3 ROM based on 4.2.1 went into a better direction as some Mali blobs could be used, but close to nothing from the 4.1.2 ROMs...
@incisivekeith It may be "project better", but not project butter.

All we need is the official source code and then everyone will be happy n_n

First of all this is not one v thread or an iOS speed competition. Different devices get different sources to work with. So it doesnt mean that one v is superior. I am happy that at least cm team is giving us nice smooth, fast and daily ROM. TW is for noobs. I don't care about other devices or bull**** until I choose them personally. High speed camera was just for fun...
Cheers from Hell.... :sly:

once you remove bloatedstuff, like automated test, and about 30 others, own risk, reboot, flush cache/dalvik, you will notice considerable improvement, most of the time, but yeah it still stutters sometime.
damn endless tweaking, dont forget some to disable some triggers on boot fo apps you only need on demand.

Anyone?

Have had a lot of problems and compatibility issues, I love the options but the glitches and errors you get are just overwhelming. Plus you lose that superb camera that Sony have given us. There are some great mods you can get on aosp like double tap to wake, but at the end of the day the problems outweigh the good. Sad really as I'd love to have one of them ROMs as my daily driver and keep the goodies that Sony offer.
Problems:
Camera glitches (works after a while)
Calls hang when hanging up (some ROMs have problems making calls altogether)
battery drain, its no secret, unless you ROM is balanced, you're going to have this happen.
Certain apps don't work ( for me this was the jawbone UP app, simply didn't sync the app with the band)
Ui force closes, doesn't happen a lot, but they do happen.
There are probably more but it will depend on what ROM you choose, there's a good few of them out there, if it wasn't for the jawbone app no working I think I'd have put a lot more work into it, my favourite was Carbon ROM, it is a brilliant piece of work with a great dev in control, it isn't an official version but its been done very well and its been my favourite up until now.
Just switched back to monxs ROM, stable and it works with everything.

Help! Why am i facing performance issues with custom roms

Hey guys. I usually wouldnt have made a thread like this, but honestly, i am getting tired trying rom after rom to find the one that works. I am the sort of guy who switches phones pretty often because i like what Devs at XDA are able to do to customize them. So i have recently started using higher end phones, and coming from mid-rangers i expected awesome performance and lag free experience. My last device was a one plus 2. After switching to mi5(which has a better processor), i have been experiencing lag spikes with rom. None of them work perfectly smooth, I would go to the depth of saying that my old Nexus 5 provides much smoother experience compared to this. Surprisingly, this is not the case with miui. The stock Miui rom aswell as my current rom(cpMIUI) are both super smooth(as is expected out of a sd820). I am stock android guy though, also google camera port doesnt work on miui. I just wanted to confirm if it was just my unit or is everyone facing similar issues. Buying a sd820, i dont expect something as simple as pulling down the notification bar to be laggy. Also. this issue is more prominent with Lineage OS and Lineage OS based roms. I found AOSP rooms to be generally smoother, but still, laggy enough to notice. This really wasnt the case with OP2, and i honestly wouldnt have switched if it wasnt for the amazing camera of Mi5(only with GcamMod ). Any help would be much appreciated. PS: I have tried custom kernels, even those which overclock this sd820 to normal frequencies. But no luck . I really dont have the budget to switch phones rn, and i would like to stick to mi5. Hope someone can help.

Mi devices works better with MIUI... That's just the way it is. Custom rom experience on Mi can't compare with the likes of Oneplus, Nexus, or maybe Pixel...

u can install Gcam in miui just use magisk to root and add camera fix module
Gcam will work in miui9
am using los15.1 and most of the apps freezed now its smooth and giving good battery life

All lags, freezes and scroll stutters caused by kernel. All oreo kernels based on HMP scheduling with perf daemon. And don't know why, but it cant provide smooth FPS while ui drawing (maybe some bug with frequency drops). So, 90% roms based on Oreo will lag while drawing UI all time (you can check it in dev settings > Profile GPU Rendering). Some roms trying to avoid this bug, like LOS, AEXMod with some tweaks in governor. This 2 roms much smoother than other. Or you can change default governor from Interactive to Conservative (root required). It brings massive boost on ui drawing smoothness. Or try something based on EAS kernels (Purefusion, JDC AOSP). But these roms based on 8.0 Oreo.

Thanks for a constructive reply. I am not using LOS because of the fingerprint delay bug, also i found LOS to be the laggiest of them all. But i recently installed Cosmic os 8.1, and this one seems to be rendering fine. It is using the priima kernel i suppose, with interactive governors and cfq for io scheduling. Also, i just checked, it has oc'ed the sd820 to normal frequencies (2.15 and .16)
Also, i have tried Floppy kernel, based on all 3, Google, linaro and ubertc. Also, i tried switching the governor to zen(the one i am aware of thats made to make your ui smoother). This issue is not only persistent with oreo roms, but also the nougat roms. But i have been happy and impressed by cosmic, but i will keep on switching roms and hopefully would be able to provide some feedback to the XDA community.

I will try that one. Can you link me to the module thread?

Hey guys. I usually wouldnt have made a thread like this, but honestly, i am getting tired trying rom after rom to find the one that works. I am the sort of guy who switches phones pretty often because i like what Devs at XDA are able to do to customize them. So i have recently started using higher end phones, and coming from mid-rangers i expected awesome performance and lag free experience. My last device was a one plus 2. After switching to mi5(which has a better processor), i have been experiencing lag spikes with rom. None of them work perfectly smooth, I would go to the depth of saying that my old Nexus 5 provides much smoother experience compared to this. Surprisingly, this is not the case with miui. The stock Miui rom aswell as my current rom(cpMIUI) are both super smooth(as is expected out of a sd820). I am stock android guy though, also google camera port doesnt work on miui. I just wanted to confirm if it was just my unit or is everyone facing similar issues. Buying a sd820, i dont expect something as simple as pulling down the notification bar to be laggy. Also. this issue is more prominent with Lineage OS and Lineage OS based roms. I found AOSP rooms to be generally smoother, but still, laggy enough to notice. This really wasnt the case with OP2, and i honestly wouldnt have switched if it wasnt for the amazing camera of Mi5(only with GcamMod ). Any help would be much appreciated. PS: I have tried custom kernels, even those which overclock this sd820 to normal frequencies. But no luck . I really dont have the budget to switch phones rn, and i would like to stick to mi5. Hope someone can help.

Absolutely yes! People were blaming me also for using antutu, because I had this doubt, then discovered that the kernel uses a strange sort of cpu scheduler which causes a performance drop of 20/25%, (still can't fix switching performance profile) results were different switching to a custom kernel. I think that people when create new roms they just steal LOS kernel, so that's why this issue occurs in more than one rom.
Anyway I also prefer the stock android camera, and I like to use the "classic" way instead of magisk thing (never liked that), just download GCam, then remove in the framework folder the camera_experimental.jar (or something called like that) and you should be fine, there are some little bugs too but is is usable.

So which kernel are you using rn? Cosmic OS comes with the priima kernel, it is the best experience i have had by far. Glad to know i am not the only one suffering stutters, but also kinda disappointed to see this happen.

Yea, me too, and there were people who treated me like crazy lmao, imo is a kernel scheduler issue, btw Idk why that happens , anyway there are plenty of custom kernels, in particular I used Floppy which fixes the problem.(Still need to tweak some kernel governor settings)

Aye i tried floppy. Didnt quite work for me. Regardless, priima is working fine. I am thinking of switching to other roms. Will try the floppy again, thanks for the advice.

When i said it needs some tweaks, that is because it works in a strange way, the performance profile in the "Battery" section of LOS needs to be set to something higher, that controls the CPU, meanwhile there I also used an app called "Spectrum" that lets you control the GPU performance profile (Even though it should be control CPU), you need to set all of those to "Balanced"

Interesting. I am busy this weekend, but i will surely test this one after i come back.

Yes

Hello, I have the same problem. My MI 5 only works on miui. Any other newer rom with android Oreo brings me problems, slow looks like snapdragon 4xx. Game performance gets horrible. But they are only in the most recent roms, because in the stable JDC Team 7.1.2 rom it behaves absurdly fluid and fast, in Lineage 14.1 as well. I do not know what causes this but I can not use any more Oreo roms. I prefer Pure Android but can not use the new roms at the moment, I should settle for the nougat or miui roms. Well, I'm not saying that the new roms are bad, the work of the developers is wonderful, congratulations to everyone, but something in the new roms does not behave well.

Try the cosmic os. It seems to be working amazingly well. Also Los never worked for me, full of stutters and the ofc the fingerprint delay on lockscreen issue. Also yeah, jdc aosp should work, in my experiments, all AOSP based roms are working fine, there is some issue with Los kernel, and hence with all roms based off of it.
