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.

[Guide]Android System/OS Battery Drain FIX

After Installing Custom Mods and rooting on Oxygen OS I was experiencing a Android System battery Drain .
Also in custom Roms based On OOS I also had the same problem.
I was draining 35-40 percentage of my battery in a charge cycle.
I searched alot past 2-3 days on my phone to see which process is causing this Drain problem.
I found many but stoping them didn't fix it .
Finally today when I found that after SuperSU was installed
It was causing the Drain so I found a fix for this
Fix for all Roms having this problem
-Go to SuperSU app
-Settings menu
-Enable trust system User
-and enable grant permission during boot
-Then put the phone on flight mode and wait for it to cool down.
If this doesn't work
-Try setting default access to grant
-Enable MultiUser access
Hit the thanks button if this helps
Also tell me if this helps in the comments
Remember to follow all steps

Doesn't work still battery drain and phone always warm

Thanks for sharing but both solutions are security risk. Maybe Magisk is solution till SuperSu is fixed (hoping that it IS the culprit).

Try to delete all of the mkv files. That helps for me. No battery drain at all

i would say "kindda" help. cause still android system drains. but, a bit less then before. i would like to see some more days.

I switched to Magisk and drain is still there so reason is something else seemingly. It has something to do with FW/Modem. We all need to deluge OnePlus with requests to fix this mess.

Helps me
My current battery cycle

For me clearing the Google Play Services database solved the battery drain.
Apps,
Google play services
Storage
Manage Space
Clear all data
I then remained on that screen and restarted the phone into recovery without returning to the launcher.
In recovery clear cache only.
Reboot
Since then I have had no problems at all (though I am running complete stock no root)
No data is lost but you will have to add cards to android pay and set a couple of other items when prompted (like default backup account etc).

I mean no disrespect to the OP when posting this..
Isn't setting default root access to "grant" a crazy big security risk? Potentially malicious apps could reboot recovery in the middle of the night, flash some REAL spyware and feed back all your passwords without you knowing and could compromise your online accounts, still have to be installed first or some exploit would have to be found, but it just seems the risks outweigh the benefits.
Are you sure it's not another app you've consistently installed? F2fs? Clean installs + factory resets? Checked your signal strength lately? Wi-Fi + Bluetooth scanning? Facebook/whatsapp/etc installed? Google location history? Different versions of twrp? Titanium backups? Uncheck the the option in android settings to Backup and restore android apps? Installed several versions of older supersu?[ R4, r3, r2, r1, r2d2?]Franco kernel? [HIGHLY RECOMMEND. All the other kernels I've tried leave my device pretty warm, but franco keeps it cool), or Anoint your phone with luxurious oils, passionately bathe it and whisper sweet things into its microphone? [References here->
]
I just wanted to make my thoughts known, some newer users to root might come by, try and follow these steps hoping for SOT gains, and needlessly compromise their phone in the process.
If you persist in believing cf supersu is the root cause (that's a knee slapper!!) I think trying another supersu might be a better way to go than ticking all those options. Say like, phh's or CWM.
Again, I mean no disrespect to the OP. Just my thoughts.

Forget about SuperSU, You guys have no idea what causes the andriod OS drain after flashing.... So stop blaming kernel, SuperSU, gplay services etc.. The answer is out there in forums.. Feel free to browse and search for it...

I saw you also sprayed ppl with their own bs on Blu spark thread. All i can say is I roam those forums a lot myself but haven't come across a clear stating about these issues (apart from the SELinux shenanigans). So what about you flood us with your great wisdom instead big boy?

Read it carefully though.. Explains why andriod OS drain battery more in first days (Not cycles) after flashing rom.. More apps, more the drain..
Tl;Dr for lazy people out there... Andriod os drain is present because Google itself has changed how andriod works..
On side note, I don't spread bs.. I just put my observations. It is upto people to fix it and accept the truth or get emo over it..

I read this post from Rovo long ago, and I of course was taking about abnormal drains they were occurring long after reinstalls or new ROM flashes. It's well known, the rebuilding of caches etc.. Anyone complaining before this incompressible period should be treated like you do. Also, still thanx for minding sharing something at least and on a SECOND side note, read again, I never said you spread bs, pretty much the other way around, i was just suggesting you enlighten us instead of "spraying people with their own bs" like for example, on the Blu spark thread where I know you were putting whiners back in place. Cheers.

I am using magisk, so what about me?

Nexus 6 requires rebooting every day or so as it slows down to become unusable

I have a N6 purchased Dec 2015 new from Amazon. The only mods, if you can call it that is, I have unlocked the boot loader. I am currently running N6F26Y sideloaded via ADB.
The phone was great when I first got it but now after about a day or so of usage it becomes slow and sluggish and unresponsive I have to restart it to use it. I have done a factory reset a couple of times which gets it back to normal for a week or so and then the problem recurs. Occasionally I will delete the cache which also helps. Snapchat is one of the worse apps - crashes the phone regularly and is a very slow app.
Also the camera can get very slow often taking seconds to take one photo.
I love the phone but it's becoming unusable now. The contrast between this and a new phone (I have purchased a Moto Z) is like night and day. The Moto Z runs instantly, has no lag and is a nice phone. But what I like about the N6 is the large screen which makes it great for videos etc.
Short of perhaps flashing some custom ROM is there anything I could be doing?

I'd recommend flashing a rom like pure nexus, super stable that should fix your problem, otherwise you've done all you can and is the easiest fix

Hello,
It seems like some apps are really slowing down your phone. I use my N6 at home for web browsing mostly as I have a Pixel XL now. Just like you I love the screen size.
The camera has always been slow fore, because of the time it takes to focus...
Did you try using your phone a few days without Snapchat installed? Maybe you also have other misbehaving​ apps installed.
Uninstall Snapchat and other apps and start from here. Reinstall one per one with a few days interval. See if the issue still occurs.
Installing a custom ROM + kernel will likely speed up things a little bit. I second @Dugaldrob with Pure Nexus and I'd suggest ElementalX kernel on top. Running this combo on N6, N6P and Pixel XL and they work flawlessly.
I don't believe installing a custom ROM alone will fix your issue though. Stock ROM shouldn't cause the phone to slow down to the point you need to reboot to use it.
Finding the culprit will...
Good luck...

First step is to remove Snapchat. I rarely use the app and only because my daughter sends stuff on it. I am going to tell her to send me stuff via another method
If that doesn't work then it's a new ROM. I have performed ROM installs before but have never flashed a new kernel on a phone before so that will be a new experience. Hopefully I won't brick the phone

I've been running Pure Nexus and wanted to let peeps know I put Nitrogen on and man it's so smooth, my wifi tether is back and I went to sleep last night with 50% battery still. When I installed it I opted for the nano gapps I think so like 175mb for minimal apps and maybe that's why it's running so efficient. Maybe I could have re-installed Pure Nexus with a clean install and it would have gotten better but it was a good time to try something else. Also when Nitrogen got an update I was notified just like stock and it downloaded. I didn't even know these could do that. Anyways give it a try and you might just switch back. I was looking into new phones but if it keeps working so smooth with battery longer than a day then I'm fine for now.

Snap chat is not that big of an issue. What I have found to cause the device to slow down is normally almost full device storage and a crappy cache release code in apps. Some apps don't release their cache properly. So it causes lag. This is why a reboot seems to fix it.
While a custom rom may fix this issue it is not the solution. The proper solution is to find what is causing it and fix/repair/ditch it.
Worst offenders for crappy code in my thoughts. Other will disagree with one on this list I am sure. So don't bother. I know people swear by it. It runs like crap for me at times and causes my whole device to lag until I close it out.

3 Google Chrome ( don't do it lol)

I can confirm this, because I've removed these apps (-whatsapp) and also decrypted the data partition...
My N6 is fast.
Maybe a lite stock ROM and an other kernel is a good start.

Currently I have FB, FB messenger, and Chrome but when I installed gapps I chose a super lite install so tons of bloat and google apps were not installed and my battery has gone way up and it's so smooth. I'm sure even when we don't use apps they're always doing something in the background. I bet you're right and a stock lite ROM would be good too with the minimal bs apps.

Thanks for the advice. Of the list of apps above I have only Chrome and Hangouts. I really can't see replacing either of them.
I also should have pointed out that the phone locks up randomly requiring a hard reset. I wonder if an errant app could cause that or I have some RAM problem. Certainly on a PC bad RAM can use in Windows a blue screen or something but perhaps Android isn't so forgiving?

I would flash TWRP, flash supersu in TWRP to root, make a complete backup in twrp, then remove whatever Google apps you're not using with a system app removal app. Getting some of that bloat off the device should help. If it's still laggy, then look into a custom ROM. I run Tesla on my Nexus 6 with none of the issues you're having. I don't decrypt it either

Running abdroid 7.1 here. I dont get any slowdowns, at leas until the battery doesnt drop below 50 and 25 percent.
Im running a custom kernel and my phone is rooted. Everything else is stock.

Can you flash a custom kernel and presumably TWRP without wiping the phone? If so then might try that before a custom ROM

Hello,
Since your bootloader is unlocked, flash TWRP and install the kernel, no problem.
Might give you a slight boost at first sight, but your device will likely slow down over time anyway...
Cheers...

I'm on 7.0 with the April SP. I have dozens of apps installed, including Hangouts. I use Firefox for browsing, I like it better than chrome (and you can install an ad blocker).
My camera slows down when the battery is under 40%, and the whole device slows dramatically, though not unusable, at or below 5%. But otherwise, no issues what so ever.
One solution that I have not seen suggested here is resetting the device and NOT taking the Google account backup of all your apps. I would suggest making a completely clean install of the factory rom you have and installing one or two apps at a time, most important to you first. And do this for a few days/weeks until you find the app that's misbehaving.
Although there are general bad players out there, this bad app could be unique to your device. Just because all devices of the same model have the same specs and components, doesn't mean that there isn't variability in parts quality.
I would do this before trying any new roms or kernels. Find the true problem first.
Good luck!
edit:
I had another idea: Go into your battery stats and network stats and storage stats and see if any app seems to be using too much of any, or all of the 3. This may get you the answer more quickly.

Severe battery drain October update

for 1 week the battery doesn't last a day, and I hardly use it, and I don't have thousands of apps, etc. One question can be made a reset to this phone, since at the beginning it was perfect ...
Thank you and is the same thing happening to someone?

Did you make analysis which applications use net/wifi/gps in background? issue wakelocks?
Did you check whether it is related to personal revival of infamous CPU frequency sticking bug, solved long time ago (and. if yes, did you clear Dalvik cache, etc.)?
Did you disable all unneeded apps (including pre-installed trash like Mi-Services).
Are you using battery saving mode? IMO switch it off immediately.
Did you set which applications may work in background? Having root you could also krystalize most of applications in more detailed way.
Have not you killed your battery freezing it or charging it permanently?
I am asking all this because nobody else is complains on this specific update and this specific issue in several forums I read from time-to-time (except that usually many complain on initially low battery capacity and now many complain on installation problems with this specific update).
One single app working in background and using net/wifi/gps can drain battery in a few hours.

thanks for responding, as I always have the phone only with the wifi on and the rest all off, I do not have many applications that consume battery only the WhatsApp, you can do a hard reset to this device? as it came with android one and now has android 10

Hmm, stock ROMs for MiA2 were/are Android One, versions 8.0, 8.1, 9.0, 10.0. And yes, if you did not make factory reset updating from 9.0 to 10.0, you are to make it (beware losing user data in phone and forced initial setup)

Question Buggy software issues

I recently bought the redmi note 11 and updated it to the latest rom of miui 13.0.1.0 stable which is on top of Android 12
Now I am seeing the following issues
1. Ringtone / Alarm / Notification sounds not working
2. Keyboard not opening sometimes and gets stuck, only restart helps
3. Apps start to hang and after that phone does not connect to internet at all even if wifi is connected.
Anyone else facing the same issues if so how to resolve them?
I am looking to install a custom rom if things persists but I don't want to void the warranty yet so any official way to resolve them?

It's always good to do a factory reset after bigger OTA update. I'm not saying it will fix your problem but give it a try. There were many similar situations like yours and this helped them.

I did it multiple times but did not help

Just in case you didn't do it this way, it's not the same, flashing firstly, then wiping, but the reversed way, formatting data, to receive a major update, and search for the fastboot latest version, if it exists, I didn't look for, so I don't know.

@asuna594 Did you somehow fixed that problem? After upgrading to A12 I have similar problems: Often no notifications (like Whatsapp), even after unlocking the phone (I manually have to open WhatsApp to get new messages).

I tried ROM flashing the phone with an official ROM from Xiaomi website. But it did not work. So I got a new phone under warranty. It was a painful experience after buying a new phone.

Oh, great I'll try factory resetting the phone and hope it helps. If not I have to contact Xiaomi... thanks!

I had a lot of problems on A12 from battery, performance, to questionable feature implementations. Downgrading to latest A11 was the most stable option for me, though you will miss out on the security patches and some new features. Maybe you can try Xiaomi.eu or custom ROMs and see if it works for you.
Currently using an Android 13 custom ROM and have almost the same performance and battery usage, if not better than the previous Android 11. Definitely better than stock MIUI A12

Thanks. I just resetted my phone and reinstalled (almost) everything. Will see if it works now... if not I'll also try to find a custom ROM (which might be difficult since I have the 11s, not the 11).

Ah I see. There are little or no development for Mediatek SoC since they don't release the source codes to public. Hopefully the reset will fix the problem
Another thing that might help is to let some apps to run without restrictions, let them autostart, and disabling Battery and Performance either by revocation or ADB to prevent it from being closed. More details on here

Thanks for your link, I will try to remove powerkeeper if my phone is still buggy because of MIUIs aggressive power management

I hope my problems are fixed now, at least most of the time notifications work well. What I did:
- Factory reset
- In Settings I've search for "Special Permissions", went to "Unrestricted Data" and toggled WhatsApp to "on"
- Switched the region of the phone to "India", searched in Settings for "intelligent scenarios" (at least that's the translation german to english) and switched that setting to "off"
- Disabled Memory Extension

Indonesia rom work good
