Why people say "ROM optimizes after couple of reboots" - LG Optimus Black

Hi,
U am wondering why do people advise to perform couple of reboots before custom roms start working optimally. I am a bit computer engineer and I can't imagine, what can happen after e.g. third reboot, that didn't happen before (unless you provide reboot counter), and what could speed up the device (or something).
Can anyone elaborate it?

Well... One time makes sense. You install new things, for them to fully activate a restart hence the reboot is logical. May be there is something to it that i don't know but i don't see how multiple reboots help... Some hardware becomes optimized after used for a while but software... Interesting. I'd like to know too. A

Well, when you shift to a new rom, the dev always insist to wipe the dalvik cache for clean install. So, at first boot, it is built. But after the first boot, when the system loads to a working state, all the services are automatically configured as per their functions and defaults. I mean, not the configuration of an app, but the settings and services (and perhaps their cache files as well)..... which should be playing a major impact, so that after next boot this doesn't repeat and device load fully optimized all the next reboots.
This may also be correlated as to why very often you don't need to wipe dalvik cache while upgrading existing rom; but you should always while trying a different rom.
cmiiw.

I agree that I dont quite understand why that is the case but it seems to help.

I gree too...
But it just me or anybody else feels diffrent -in term of good way- after couple of reboot. it just make my zeus work optimal especially in battery efficiency.

ART on droid turbo

Hey all.
I tried switching the runtime to ART and lost all use of the power button. So I'm back to Dalvik again. Is anyone else having this problem and if so, have you found a way to fix it
Thanks!
I've been on ART since Monday and have had no issues
Until you do a reboot, then it recompiles the run time all over again. I've also been being some random FC's on phone and ui but other than that it's fine
I switched over to ART and it is optimizing 60 apps after every reboot ? going back to Dalvik for now also battery life for me has been somewhat shorter..
Sent from my Nexus 7 using XDA Free mobile app
I was getting rather crappy battery life after restoring apps via helium phone was awake 100% of the time, I switched to ART and now the phone sleeps. As a result battery life has improved!
I've been running with ART since I got it on release day and haven't had a single app fail. Maybe I don't have a lot of apps or something, but so far, it's running great.
Anyone been running ART?
I enjoyed performance on my HTC M7, but the battery life seemed shorter. Could have been other factors, but am curious as to what people are doing on Turbo.
I don't have any performance lag, so I don't imagine this things running any better than it is. Especially at the sacrifice of battery life.
I've roamed google and can't find an answer. I tried to switch to ART...3 HOURS ago! It keeps getting stuck! I read some forums and rebooted, it'd say "upgrading x out of y apps" but the Y is always different (up and down) and the X it gets stuck on is always different! at first I assumed because I have a podcast app that has over 1.7 GB of data, but going on 4 hours?
Worse, the recovery partition isn't showing up to wipe dalvik cache or data- it just says NO COMMAND, and does not respond with any menus. Tried the factory reset, and tried even using adb to wipe. Nothing is anything other than stock here. nothing is responding. It just keeps going back to the "Android is upgrading" Any ideas?

I've noticed ART doesn't seem to play very well on mine either. Upgrading apps everytime you reboot. Boot sounds play when on vibrate/silent. There's quite a few quirks but those stood out the most to me. When lollipop is official, we won't have to worry about that nonsense. For me, I'll have this phone about 10 more days before I send it back to Verizon.
Issues with ART aswell... Several apps optimize after every reboot.

After waiting about 6 hours, and even trying to wipe cache and everything, eventually I had to wipe data and do a factory reset, and got ridiculed on the private forum for the soak on even tryingART (oddly). So for the moment, I'd say we wait on LP b4 using it consistently.
I ran ART for about a week or two. The optimizations grew on every reboot. Switched back to Dalvik and my battery life improved.
Stop rebooting then . Art runs great. Better battery and snappier with window animation s turned off. If u have problems its either your phone or operator error

Naive comment. If there is a phone problem, you likely will need to reboot. Operator error doesnt cause a phone to reboot either.
Why use something buggy and broken like art on kitkat when the advantages are barely seen and the disadvantages are huge?

Why buggy and broken? Besides the optimization on boot, for which we don't know whether it's a bug or has its reasons, art runs great on the turbo.
I can't say much about GUI performance, the GUI is blindingly fast on dalvik, hard to say whether it's blindinglier faster on art or not, but it's definitely not slower.
Battery life on the other hand makes a huge jump with art! Especially system uses way less power, in my case less than a third. And that's definitely worth it!
There might be issues with some applications from the play store (which is most likely a compatibility topic as with any major android update and not one of bugs) , so far I didn't run into any, though, and I've got plenty of apps installed and in use - none of them exhibit the slightest issue at all.
All this said, if you don't run into any trouble with any of your key applications, I definitely and highly recommend art!

Interesting. Did you figure out where the power went to? Did you compare fairly, as you had the phone new, usage pattern and installed apps might have undergone a fair change.
As a side note, I only tried it with the latest update, maybe that makes a difference as well...

I switched to ART maybe a week after I got the phone, so I was through the new phone setup. I was on that day 1 update (.15 or whatever) when I was trying it. I wasn't scientific about the testing at all, but I did use it for two weeks so I think it was a pretty comprehensive representation of my usage patterns. After switching back to dalvik, my standby time in particular jumped noticeably. Different strokes for different folks? I don't know, but personally I will be sticking to dalvik while on Kit Kat.

Apparently, pity. Looks like it ain't a sure win, thus. Guess, as you said, one has to try it out and see whether it works out for your particular combo of apps and usage...
Thanks for shedding light on that dark side of art.
I'm on the maxx, didn't get much out of art for better or worse. I didn't notice any performance difference nor change in battery. I did find the rebuilding annoying though since I reboot at least once a day after I update my hosts file and I'm trying various other changes in exposed and so on that require a reboot.

My Experience with Lollipop on Nexus 7 (2012)

Hello,
I've updated my Nexus 7 first-gen recently to Android 5.0 and since than have spent a good amount of time using it. I use the tablet for work and fun through out my whole day, so snappiness is a big factor for me. With the 4.4 update, the tablet just got a lot slower, sometimes I needed to wait for a few seconds before I am able to kill a task. Clearing cache didn't fix the issue.
Made me think about that 5.0 update a lot. (Note that I actively started using the tablet only a few months ago. I had it for 2 years but broke the screen 3 weeks after buying it and only now I decided to repair it.)
The 5.0 update it self took a good 45 minutes. When I loaded it up for the first time, man it was buggy, I couldn't complete a single task without it bugging out. All of the Apps and settings were there untouched. The first thing I did, was go into recovery mode and cleared the cache. Then I cleared the cache for every individual app. And that boosted the performance by 100%. Next, the animations, I cut them down to 0.5x and turned on GPU rendering (just for testing) turns out that helped out a lot. I didn't notice a difference in load times, like some articles suggested.
However there are a few quirks, the sound lags behind the slider, so if I crank up the volume to MAX it will take a moment to do so. I often found my self having to tap the apps drawer button more than once to open it. And the killing of tasks is not as easy as before, now you have to slide from one side to the other in order to kill a task you can't just kick it to the side. Also, the auto-brightness is really aggressive so I disabled that. The WiFi status, when you click on a WiFi connection seems to be broken since in portrait mode all the letters are separated, and at first I couldn't make out any of it. And the biggest downer for me is the keyboard, I think they didn't do any favors with it. I have larger thumbs and it will take some time getting used to the keyboard. These are all small things, but they affect my experience.
Now the good stuff, where do I begin? The interface, it's great I like the design and the contrasts. Performance, I guess that's the biggest question since this is not exactly cutting edge hardware. To summarize it, it's good. I haven't had any issues since I cleared the cache, apps are running as they should, games as well, multitasking is as expected, fluid. Later on I switched the animations to 1.5x and 2.5x. no issues there. Boot up times, something completely irrelevant to me, but since there are people that would like to know, it takes around 30-40 seconds to boot up. However, Chrome is still the biggest enemy. If you want something to make your tablet miserable and make you wait and get frustrated because of it's unresponsiveness, you won't need to search far, just get Chrome.
All in all, the update was a step up, and an improvement.
These were my 2 cents on the subject. Hope it was of use to someone.
thanks for the review. I also updated a few days ago when the ota came through. So far, I'm experiencing terrible lag. I don't have anything stored on the N7 and don't have many apps. There is a ton of available storage on my 32gb. I did a factory rest about 3 months ago, as I like to every now and then to give the N7 a fresh start. I think I may have to yet again and keep my fingers crossed. Unfortunately, it's unusable at this point.
My experience has been variable, but not unexpected. In the past I have had issues with installing OTAs resulting in poor performance -- sluggish response to touch, certain apps immediately displayed odd lag, etc. Going from 4.4.4 to 5.0 was no different. So, I performed a factory reset and the effects were stark. The performance is exactly where you would expect it to be for Lollipop i.e. it is smooth.
HOWEVER, all is not well. There seems to be a set of problems that I suspect is related to Lollipop utilizing the ART runtime. Certain apps, even before performing a factory reset, were really really slow when running the first time. I have experienced this before: when I tried out ART when it became available on the Galaxy Nexus. Two common apps this occurs with are Facebook and Mint. Who's to blame? The app developers? Google? Don't know but hopefully these issues get resolved soon.

Ugh, that is quite an issue. Have you tried wiping the cache? You should check your usage, you might be able to find out what's hogging your system, unless it's the OS it self.

I also tried out the ART on some devices, mine were not even supported. There were a lot crashes but I also noticed some performance improvements.
Does factory reset also wipe the cache?
My Lollipop experience with my 16 GB WiFi-only Grouper isn't as good as yours. First, I thought I messed something up by rooting it with NRT, but after a manual factory image (flash-all.bat failed out of the box) without root it didn't get any better.
Most time its not as responsive as my N5, I've already had 1-2 minute hangs followed by hung apps (Google Search/GNL, system in most cases) and heavy lagging under most conditions. From time to time its getting close to 75-80% of the smoothness experienced on the N5 (which has better hardware, of course).
I have no idea what went wrong, I've already enabled 2D GPU hardware acceleration, but I'll definitely wipe the cache in recovery once more - you never know...
Thanks for the extensive review - Chrome is just a pain in the a** if you don't have at least 2 GB memory available.

One thing I forgot to mention is that after the cache wipe the tablet was fairly fast but I also went into Settings > Storage, and noticed I have a lot of app data which frankly shouldn't be that much. I then went and cleared cache manually on every app and as it turns out, I managed to scrape off another 1GB there. So, I'm not sure how that would affect the overhaul system performance but it sure helped me get the snappiness I have right now.
Looks like wiping the cache had an impact on performance. I wasn't able to play around much, but it definitely felt faster after first reboot.
Too bad I just noticed my user partion only had 6,x GB (8 GB image obviously) - there are so many ways you could f**k up an Android system - so I'll have to format user data once more, approximately the third or fourth time in the last week.
Sometimes I understand why people fancy those awful Apple devices, but let's hope the speed boost persists.
Go in and delete all the apps in system folder that can be installed from play store and are not needed. After installing the lollipop images you have 11mb in system which seems to be main cause of lag. I freed up like 160 mb and no lag or stuttering. Not sure why google kept things like dialer and other things unusable on the tablet in there.
Also get now launcher and delete launcher.
For even better performance get faux kernel (Set kernel up to his recommendations) and/or install aosp 5.0 F2FS with minimal 5.0 gapps.
Oh I do have a problem with WiFi being weaker on 5.0 though.

i am getting terrible lag too. last week i updated with the OTA file. wiping the cache improved performance but only for a short time. i guess eventually if ii want the speed back on my 2012 nexus 7 i am going to have to root and go back to jellybean

Thanks, that sped up things significantly. It's definitely a memory problem, because event on full stock setup you're getting glances of Lollipop smoothness.
But WTH is Google delivering a potentially lagging factory image? Couldn't they just resize /system by default in order to fit in all apps nicely? Well, that's Android - if it doesn't work, you have tons of options to fix it.
After my old N7 screen broke, I got a new refurbished 16GB unit for about US$100.
Had some bootloader issue earlier while trying to flash lollipop, and had to revert back to 4.2.2. Then it got all the OTA up to lollipop, and is running really well since.
Loving it now, better than most non-lollipop newer tablets around...
Lollipop is big disappointment. I hate new notification (double swipe down to access settings)
I am back on 4.4.4 Slimkat rom with Legokernel and f2fs
now is system smooth without lags
Listening to some of the advice in this thread, I rebooted into Recovery and wiped cache (I did it 3 times, because why not, right?)
In addition, I went into the developer settings and turned OFF "Force GPU".
After doing both of those, my performance seems to have greatly improved (specifically Chrome, which was borderline unusable).
For reference, I flashed the factory image from 4.4.4, and didn't get it OTA.

Not any more! I have three new iOS devices and things are far, far worse since iOS 8 dropped. Apple now holds the lag crown. At least with Android you can revert back to earlier versions that worked. With Apple all you can do is whimper at the master's feet.

UTTER nonsense. Stop it. System being full affects nothing; it's read-only.
Is there a way to disable the storage encryption that is enabled by default? Disabling this apparently had huge performance upgrade for the nexus 6

understand what you are saying but after doing so i have no lag.
Have 2 x 2012 and both were lagging. After trying other things i deleted stuff in system and both are very smooth now. Very happy with them.
Even wiped and re installed one and just deleted stuff in system, to make sure it wasn't something else or a combo of things i did prior.

[Q] About the encryption, performance and future updates.

Hi All,
Finally got my hands on a new nexus 6 for a bargain price. I've been reading and searching alot in this subforum in order to answer alot of questions i had.
My 6 is upgraded to last ota available with the last security patches, but the phone is encrypted.
Now the question is, is either me that is over-sensible to slowdowns and juddering due to encryption, or the people doens't really notice it that much? It bugs me out.
Granted my 6 is not rooted and unfortunately due to the need of having a working phone in an hour i didn't even explored the possibility of disabling force encrypt, but afaik this would lead me to:
- Do a full wipe to keep encryption off and thus loose all my stuff
- Reinstall everything from scratch
Is that right?
Also if i got right, doing so leads to:
- Impossibility to install OTAS because doing so will re-encrypt my phone and i will need to start from scratch again
- Impossibility to upgrade to Nougat when released, granted it will be encrypted from the start
Is that right?
Also if those saying that encryption performance is almost the same of having none, why i'm having such lags, juddering, pauses between apps, low battery performance and excessive warm when used for long?
Is my phone faulty/my android version or that is what happens when you run an encrypted phone with alot of apps (more than 50 due to work)?
Thanks for those who will take a minute to answer my questions.
Have a good day y'all.

Thank you, actually i have all the stuff to disable the encryption. My point in question is, restoring a backup made in TWRP makes it encrypted again?
Because i want to avoid to reinstall everything, set my apps back from zero and so on.
Also that doesn't quite answer to the question about security patches and OTA's. Do the phone reencrypts itselfs and gets wiped if i force install an OTA or security patch?
Each time i need to do the whole process from scratch?
To change kernel, system and data partitions you need root access. When rooted OTA update will fail.
That's why many N6 users have a custom rom and Twrp-recovery installed.
To avoid hassle and reinstall data and apps.
I am using this rom: http://forum.xda-developers.com/showthread.php?p=59561445/
The dev updates the rom mostly before the official OTA .
About encryption: in daily use not noticeable.
Only backup is faster; twice.
Battery. The amoled display is consuming a lot of battery power. To avoid this I am using apps withdark themes and a black background.
So no Gmail but Aquamail.

Thank you for your insight. So i'm better off to a custom rom, updated with encryption off and call it a day?
I don't want to stick to CM or other roms, i would like to stick to official-based ones, to keep the sake of google pureness.
Thanks again.
In a short time the new version Android Nougat will be available for the N6.
I think it's useful to wait. Don't make changes before you updated to Nougat.

Yeah thats my point, the problem is that i can't bear anymore the sluggish performance and the lag, sometimes it slows down to crawl, and based on some benches i did its because the disk access is so high that even alot of cpu power is used. The phone becomes hot when managing 6 mailboxes, 4 social profiles and pages and tons of other activites.
It destroys my battery life and also the performance takes a huge hit.
I guess ill be patient and wait for Nougat to come in a form of custom rom.
Decrypt will not give you a noticeable Bett. performance.
Try the app Advanced Task Manager. To kill background activities.

Well then definitely something is wrong with my phone. It really (sometimes) slows down to something unbearable. I think i'll wait, if things gets complicated, i will do a wipe.
I never experienced such low performance not even on dual core phones. I had to reboot at least once yesterday to get things decent enough.

When a reboot solves the performance issue than try the app Quit Reboot (PhongIT). It has several options for rebooting. .
Another performance issue can be caused by the Google Play Services (searches continuously for updates), or apps working in background. Check the battery use in Settings - Apps - <app name>.
Disable the Google Plays Services temporarely to see possible differences.
When the battery is becoming warm/hot. Could be a bad radio connection. Switch to 2G.
Switch off wifi and bluetooth when you don't need it.
Delete apps you hardly use or disable them in Settings.

thank you, will take care of the things listed.
there are so many great custom roms to try, some cm based, some not, and most if not ALL of them do not have any of the issues you are complaining about.
its a Nexus; root it, and start trying the dozens of custom roms out there..
dont bother decrypting; its a hassle with zero real world benefiits, aside from back up speed, which is meaningless imo
and, all the custom roms pretty much update constantly, so rarely are you more than a few days/week behind any google updates when you use a good rom; the dev's make sure they update/add any real improvements/features really fast.

Slower and slower -> trimming -> does not work?

I rooted the P7 and installed Trimmer (ftrim) because I was hoping to speed up the phone storage as it is progressively running slower and slower.
Trimmer runs just fine (asking for root ofc), but every time it says the same amount of data (A LOT) is trimmed on the partitions, so I think trimming never happens for real.
Has anyone faced the same, both in terms of phone storage getting progressively slower and trying to trim it?
I tried this app in the past too, for me I didn't notice any boost...
What about a clean install of the whole system?
seems like the only option, but still I wonder why trimming the flash does not seem to work
Since android 4.4 trimming is in system enabled so you don't need to trim with a app.
I love to modify my phone so every month it's broken (wrong xposed modules, kernel,...) and I need to recover it... But sometimes I clean install everything so it is as fast as I buy it
ok, point taken, would a factory reset be enough or better revert to recovery and perform a full wipe from TWRP?
You could do a factory reset first, and then decide by your self if you want to do a full wipe

Best Way to Restore Apps after Factory Reset

It's been almost 4 months since I bought my Samsung S20 FE (4G Snapdragon Version). Since then I've had some issues with the phone heating up while doing light stuff on it. I've asked for help before here on the forum and you guys helped me reduce this issue, but while talking with other people who own the same device as me, and that don't have this issue, it was suggested to me that I should try to factory reset the phone.
I've done this before, but since then I've heard that both the Smart Switch and Google Backup can cause overheating and battery issues, while others say that I should use the Smart Switch because only Google Backup can cause this kind of issue.
In your guys opinion and experience, what is the best way to factory reset and restore the phone while avoiding those issues? Smart Switch, Google Backup, or simply backing up the apks using something like Alpha Backup (or any other backup app that you guys find more useful) and starting from scratch?
Thanks in advance.
Try clearing the system cache.
Toggle off any power management settings you enabled in Device Care, only fast charging should be enabled.
Do not use any power management; deal with power hogs directly on a case by case basis.
The reason you're doing a factory reset is to purge bad settings, apps or malware.
If you used SmartSwitch for apps it may be the cause. Don't.
You can use ApkExport to make installable copies of all your apps less data. No Playstore is then needed.
It's usually better to find the root cause rather than do a factory reset. If was a bad load, a boot loop or malware, factory reset*... and don't repeat the mistake. Correct the mistake without a factory reset if possible; you want to ID the cause of the issue if at all possible to prevent doing it again... and again.
*if you did a major firmware upgrade ie 11 to 12, factory reset.

Well, I tried just about everything with this phone.
Using with both power management settings on and off, with or without Good Lock modules, with the refresh rate set on 60/120hz, with Power Saving mode on and off, with Game Optimizing Service enabled and disabled, etc.
But I can't find the root cause of this issue.
I only play light games like Clash of Clans, only occasionally playing Honkai Impact. But the device heats up nonetheless.
I know that it's summer right now and that the weather her gets really, really hot. But I don't think it's normal to feel the heat of the phone while watching a video on YouTube while people on other cities that are also really hot during summer play games like Genshin Impact or Asphalt and feel it heating up just a little bit.
I will try to wipe the cache and wait until Android 12 gets released to change my CSC (I'm on a carrier ROM and would like to change to the default Brazilian CSC) so I don't have to wipe and restore everything twice. Meanwhile I'll keep an eye out for anything that could be causing this issue.
Thank you very much.
Set Power Saving to optimized, not an issue.
Good lock is normally no issue.
Cloud apps are. FB, WhatsApp, Twitter, etc are trashware... take out the trash.
Try temporarily disabling Google play Services and see how it does. Disable find my device first as a System Administrator.
Use Accubattery to track battery SOT with its history log. Use a damp microfiber cloth to cool in hot weather or when charging in hot weather.
Find what's draining it.
It's not uncommon.
My N10+ was a hot running battery super hog... not any more. It gets 7-13%@hr SOT, >.5%@hr at night with tap on AOD active.
If your SOT at idle or using the browser (excluding vids) is greater than 10%@hr, you got some witch hunting to do.
