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.

I suggest wiping cache, because you get to keep your apps and settings.

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

Swipe once with two fingers.

I've done cleaned every thing in this ROM, repeatedly. Hopefully CM 12 will make it work!

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] 4X HD lag issue

Hello,
For the last 6 months or so, I've experienced many lag issues with my device. At the begging, I had a CM11 ROM installed on my phone, so I decided to revert back to the V20B official european firmware because I thought those lags were related to the ROM. But nothing changed, and as of today I still have responsiveness issues.
This lag issue appears from time to time, and makes my device basically unusable. It feels like the whole CPU is hogged by an application, or like I underclocked my device to 53mhz on purpose. During these lags, trying to wake up my device will take up to 5 seconds, and navigating the main screen will be nearly impossible. Also, my phone will get very hot which would imply that my CPU is indeed used by an application. Sometime the issue will disappear by itself after a few minutes, but I usually reboot the device which temporarily fixes the problem.
I have tried to disable LG MLT, and I think it helped but the lag still occasionally occurs.
I don't really use third party applications either.
I think these lags might be related to the Google Chrome browser, but it doesn't make any sense as it is an official app.
Anyway if any of you have an idea on how to fix the issue or how to find the application/service/whatever hogging the CPU I'd be grateful
Thanks !

I did experience such lags in CM11 after a few days of usage.But talking about stock, these freezes sound bit weird.You might want to check your installed apps.Download watchdog lite from play store and let it watch on agressive mode.Also check if your phone is hot when these freezes occur, might be the throttling kicking in.
I also experienced this kind of lags due to bad gapps I had installed back in the day, though stock ROM comes with gapps so it's not that.

Thanks for your reply,
I installed Watch dog lite and I'm now waiting for an alert. I hope it will give me the name of the culprit

If you are rooted which i assume you are. You can try app from playstore called "lagfix" (fstrim)
Sometimes really helps. Sometimes it doesn't

[Q] Memory Leak

Is there currently any ROM and/or Custom kernel, that doesn't suffer from the memory leak bug?
I am aware that similar questions come up on every other thread.
I also would love to try for myself. Stock KitKat and stock lollipop both suffer from the bug. On lollipop I have much more free ram, but chrome and other apps still redraw when multitasking.
Problem is, I don't want to unlock my bootloader yet, as I'm still considering giving back the phone.
Thanks in advance for any insightful advice.

You seriously want an answer to that?
Just read "every other thread", then come to a conclusion and act accordingly. Or don't, since you don't want to unlock. Your choice.

I never said, that I didn't want to unlock my bootloader, eventually I do want to unlock it. But according to your reply, I suppose you don't understand that. Nevermind.
Thanks, anyway.

Titan Prime will yield you the best results with memory, from my experience.
Besides that, all you can do is sit and wait for 5.1. And hope that it will fix the problem.

I've got a (german) XT1068, and I was on build RETDEALL 21.85-14 for the longest time (KK 4.4.4). The phone was sometimes close to unusable due to the memory issues: Almost every time I went back to my launcher (Nova) the widgets would reload (all two of them), every 5th time the whole launcher would have to be restarted. When listening to music, the player would often be killed when it's not the foreground app. This all was already with tuned settings and the like. Simply put, my Galaxy S2 was a much better phone, with better performance and multitasking (same amount of ram, but dual core only)...
I've updated to the 5.0.2 build that was (finally) released a few days ago (22.46-28). It's a world of difference. I would say the problems are either gone or at least they got the biggest of issues under control. So far I haven't had it running without a reboot for multiple days (installing xposed and associated modules tends to require reboots), but so far everything is looking perfectly fine. Widgets haven't reloaded even once, let alone the launcher. Multitasking works, even larger apps weren't killed (like reddit news, which tends to use quite a bit of ram after scrolling for a bit).
So I don't know whether it's fixed, but at the very least this is a fully-stock-option that works perfectly fine (for me), even though I'm rooted and use XPosed that is by no means necessary.

I also have the German OTA update. Everything works fine. As for the memory leak for me that is a thing of the past, was really bad in 4.4.4 and I had the same version as the above poster. Everything stopped in the background, in point of fact there was no multitasking. With 5.0.2 I can play music run a navigation app, surf the net no problem and still see over 400Mbyte free ram in setting all without the dreaded app has stopped working or seeing apps restarting.

4.4.4 didn't have a memory leak, just high minfree values I think.
Lollipop does have a memory leak (and thats mostly googles fault) and the memory management is very buggy when compared to kitkat. The memory leak doesn't show instantly, it shows after some time and you can just reboot the phone to "solve the problem".
If you want a really good rom for multitasking I recommend CM 11 or some rom based on it.

4.4.4 definitely has some serious issues on the MotoG, it was not just the min free values. I had tuned those (basically tried everything), but it made no real difference. So far, LP feels like it's a different phone.

I agree. I can't understand how people would go back to KitKat after trying lollipop. Chrome and other apps still redraw when multitasking though. :\
Let's see if 5.1 fixes that.
BTW: does anyone get graphic glitches in Tapatalk and chrome? Sometimes whole areas of the screen turn glitchy, until I switch to another app or press the back key. (Glitchy= pixels in all colours, like an overheated GPU on a PC would produce.)

Z3C 5.02 stock Memory leak or something else?

I know that there was a memory leak issue with 5.02 but it's apparently fixed before the fw was deployed:
http://forum.xda-developers.com/crossdevice-dev/sony/clarification-xperia-lollipop-fix-t3087240
So that doesn't help explain my issue. Very often, when I have any combination of Spotify + Google Maps, Spotify + Chrome, Chrome + Google Maps, etc open, the app that's in the background will just flat out close. It's stupidly annoying while driving when my music just dies, or when my navigation disappears and I miss my turns because I don't hear any audible alerts. The issue goes away after a fresh restart, and will come back usually within a day or two.
I did not have this issue on 4.4.4.
My free ram hovers around 500-600MB at all times.
RAM status today
RAM Status after fresh restart
I absolutely hate why nothing can be properly backgrounded like in iOS. The moment I press the home button or switch apps, all my open tabs in Chrome have to be reloaded. Filling out forms in a Chrome tab while referencing another app is almost impossible... This was actually an issue on 4.4.4 as well as 5.02. I have not found any way to fix this, no matter how many times I restart my phone. I don't think my old Galaxy S3 had this problem...
Why does Android make us work so hard for a properly working phone, if we can even have that at all? As a consumer I should not have to go through 7 levels of technical hell to make a phone work properly. This isn't Linux.
Sorry for the rant. Anyone know what I can do to fix this? Everyone says RAM clearing apps are bad. So that's not an option right?

.726 has this problem and as far as I can recall it was pretty serious. Fortunately in .26 the problem has been solved. It's about memory management in lollipop being poor rather than memory leak.

.26 hasn't been released for D5803 USA right? I don't see it in the firmware thread
Still doesn't explain the Chrome issue. Whenever anything is backgrounded (not closed) in Chrome, all my tabs have to be reloaded. Most of the time now, even just switching from one tab to the next within Chrome while it's open forces a refresh of the tab. WTF

I never had any memory leak issues with any of the firmwares. Try to turn off Stamina mode just to see if it is affecting (I have it off, and queue background data off as well). Make sure also you have not enabled Developer Options and checked the setting 'Don't keep activities' or some other setting that limit the amount of process you can have in the background.

Dev options are not enabled. And stamina only kicks in at 50% battery. I could turn off que data but does that have anything to do with RAM?

I just called Xperia tech support and they suggested I do this:
http://talk.sonymobile.com/t5/Xperi...uctions-using-Pc-Companion-Win-or/td-p/249946
Has anyone done this and fixed the issue?
I am apparently not the only one who has had this problem:
https://www.reddit.com/r/SonyXperia/comments/356f80/z3c_502_stock_memory_leak_or_something_else/

There's an Xposed module called App Settings that lets you force the OS to keep stuff resident in memory. Because it's an Xposed module, I have no idea if it's compatible with LP or not. Also, there's a point where you can run out of memory and experience involuntary restarts if you keep too many apps resident. Still, it's worth trying, imo.

I was told that the memory leak wouldn't be fixed until 5.1 or even 5.1.1

726 did indeed have this problem. i used the xposed module for the memoryleak fix and it did indeed work...phone was much faster.
People are saying sony phones do not have the leak but the leak affects each phone in slightly different ways.
I the new .28 USA firmware running on my phone now and it is working rather well. granted i still have the lollipop memory fix module activated but i will do some testing with it off as well.

Nope, the problem is not solved in any lollipop firmware, atleast for me. I tried all the latest, reflash and wiped all (Included Internal Data) and the problem still here. Is Ridiculous how with 2GB RAM I can´t have atleast 4 apps opened without the preocupation of they get killed for itself. I remember with my Nexus 7 Tablet in Android 4.3 had a looot of apps opened and no one get killed itself, it was a great multitask experience that I can't get yet in Xperia Z3 Compact. I tried edit minfree values, uninstall apps, change firmwares, edit services.jar, install tweaks, edit my build.prop, etc. Also I noticed with the Task Manager of System Tuner app that "/system/bin/mediaserver" is always eating more than 60mb of Ram, this is since kitkat and continues to happen in Lollipop, after of some hours, this same process can take up to 160 - 200 mb of RAM!!! The worst thing is that in other devices this process don't seems to take a lot of Ram as in Z3 Compact did. Idk, it would be good that we can improve multitask in this device.
I compared the /system/bin/mediaserver usage with a Samsung Galaxy S4 Mini and it only takes 5 mb of RAM while in Xperia Z3 Compact it always start eating 50 mb of RAM and it increases up to 160 - 200 mb in some hours. You can see my proofs here:
http://forum.xda-developers.com/showpost.php?p=60569610&postcount=9
So Idk what to do now, I hear that the only good devices that take importance in multitasking are HTC M9 (M8 and M7 too) and the Asus Zenphone because they merged their own patches to ART to improve a lot how multitasking is managed in android. I think sony do their devices to kill apps very agressive, so in this way they can presume that his device is more smooth than others but useless for multitasking. Weird...

Hmmm, idk. My GPE m8 on 5.1 is experiencing these same symptoms. Super annoying to have my music cut out in the middle of a workout. ?
I play with my food

I referring to HTC M7, M8 and M9 with Sense, because they get own HTC patches. Well, is what I hear, and also I see some tests in YouTube and the multitask is very good.

Any feedback on how .28 is running compared to .726 with the xposed fix?
Like many, I uninstalled the fix after I read the thread pointing out that having it active was pointless as Sony had already fixed the memory leak themselves, but after reading your reply, I decided to reinstall and sure enough, my phone does seem snappier. Having read the changelog for .28, it didn't seem worth upgrading unless performance was noticeably better.

I will tell you im enjoying .28 with the fix running. There are enough fixes in there to make it worth it i think

No issues on 23.1.A.0.726 here, I have averagely 250 MB more free RAM on Lollipop than on Kitkat, with all the same apps installed. :good:

Guys, the problem is not how many ram do you have, the problem is if you can multitask some apps without someone get killed. I can multitask within 2 or 3 apps sometimes, but I can't get more than that without someone gets killed...

It was to be expected that Lollipop in Sony devices would be problematic. For the time being, I prefer to stay in KitKat and then make the jump to 5.0.2.

Laggggg on Marshmallow or is it just me?

My UI freezes for 5 - 15 seconds, particularly when the phone regains network connectivity (reconnecting wifi or mobile network going from 0 to 1 bars). It's much improved after removing FB and Insta but. My launcher is even getting closed when the phone frequently, although the phone has ~500MB free RAM.
I dropped this poor phone one too many times, so before I replace it with another z3 compact, I'm wondering if everyone else on Marshmallow is seeing poor responsiveness as well.

I did have slow downs before but not like that,I have switched to Lineage and it works very well so I don't have any plans going back to stock Marshmallow.

yeah same here, i advice you to switch to lineage, you will feel like butter on the screen.

I don't have any lags at all, no launcher refreshes or whatever on stock MM. ( I don't use the horrible Facebook application)

Until 3 weeks ago, I used to have no lags at all on my stock Marshmallow 6.0.1 Z3C. I had uptime of 50 days and more and it didn't lag. Now, it happened twice in a row that my System RAM usage grew in last 5 days to 1,3 GB! It seems like a memory leak in kernel space. It's hard to pinpoint particular process. The phone is slow, multitasking doesn't work (reloads every app), my stock launcher redraws and the phone is unable to make/receive GSM calls - probably a symptom of low on memory state. I wonder, if it's caused by bluetooth driver, because I've transfered 100MB file on both occasions. I need more time to analyze this, this time I won't turn bluetooth on, so I can see if it is the cause.
Edit: I'm confident the cause is not bluetooth. Symptoms now appear after just 65 hours of uptime - . Now I tried to get rid of ES File Explorer, let's see what this bloatware did to system performace.
Edit 2: It seems the problem is gone after uninstalling ES File Explorer. Before uninstalling it had data storage set to external SD card. I replaced this piece of bloatware by open-source explorer called Amaze.

Thanks all. I was avoiding Lineage because I wanted the stock camera / DRM and their description makes it sound very unstable... "random reboots while charging", etc. I'll try it out anyway and add the stock camera back in if it runs well.

Do share the source of the issue if you find it. I'm still seeing UI lockups when the phone loses internet connectivity.

camera works like stock in lineage, don't worry about that. you can face with other small bugs but still worth to use, it is better than stock in most cases.

having the same issue since a few weeks.
device gets VERY slow (i mean like 10 seconds to open the phone dialer or whats app)
Even did a factory reset, which only helped for ~2 days ...
same problem with my girlfriends Z3C.
Something is very wrong here ...

there must be a reason that it is slow as hell in stock while it works with jet speed in lineage. something related to sony software, hardware is okay.

Wipe cache (Power and vol+ until 3 Vibrations) helped a little, but i don't put too much hope in it.
It's my gf's Phone so i kind of hesitate to install some unstable beta on it. Or is there any real stable release out there?

Sony haven't pushed out any updates for over a year, so not sure how you can blame it on MM build.
It'll be an app.
My money's on Facebook or Messanger.
No lags or slowdowns on my phone, had the same build on it for a year now.
Autoupdates turned OFF.
No Facebook/Messanger.

Guess you're right, but i can't really accept a SD801 Phone being unable to run basic apps like FB

Last year Facbook deliberatly broke their app, made it run slow and heat your phone up, as an experiment, to see what people would do. They honestly don't give a sh*t about what you think of thier app.
Uninstall it and use your browser, see if it makes a difference.
Try SD Maid from the playstore, that does some good basic houskeeping

Nope.
I do not have a Facebook account.
Therefore I do not have facebook or messenger installed.
But I do have these slowdowns :-/

I read in an italian forum that it's the Google app fault, you should unistall updates and disable automatic updates until it's fixed.

It seems the problem is gone after uninstalling ES File Explorer. Before uninstalling it had data storage set to external SD card. I replaced this piece of bloatware by open-source explorer called Amaze.
Now I have an uptime of 125 hours and counting, my System RAM usage is 0.90 GB and it isn't rising to 1.3 GB as it did before. So the phone is really smooth again. When I was checking my LogCat using DDMS, there seemed to be recurring message of ES File Explorer (estrong) leaking something, I don't remember if it was a window or an activity. What a piece of chinese malware it became. Interestingly, ES File Explorer's memory footprint was low (3 processes, 10MB total user space memory), even when leaking memory and this made debugging harder. Although I killed it, when the phone had problem (1.3 GB system memory), only a reboot worked. It totally seems like a memory leak to me.
GL debugging yours.

it works good with me ..
try to make clean install

I'm not going back to this crappy app. Once, it used to be outstanding, but they probably sold the app to another company in China and from there it went downhill. A lot of popups and ads for things I don't need. Their only purpose is to make your phone slower (bloatware) and optionally, to get money from you. I like simple, minimalistic apps, which do things they are designed for and do it right. Just this Linux approach and also "less is sometimes more".
It's confirmed that ES File Explorer makes network connections to China in background, no thanks!
