Running CM 12 (5.0.2) with M-Kernel at 1.6GHz perfectly smooth. Although it takes few seconds to open apps like Chrome or YT despite that I have /cache and /data formatted to F2FS.

When CM 12.1 comes out I will switch immediately.

Is it possible that clean cache from recovery is not working?

I tried many times to clean cache partition from recovery due to poor Lollipop performance. But performance didn't improve more than when I just restarted device. And process of cleaning cache from recovery is very fast - one second max.

But now, I cleaned cache from Settings -> Storage, without restart, and it seams to me that performance is much better!? And cleaning process is much longer, half a minute at least. Is it possible that clean cache from recovery is not working?

Device is stock, locked and updated to 5.1 through ADB pushed OTA.

After many months with kitkat 4.4.4 Mahdi ROM and last weeks 3-4 different lollipop ROMs , I returned for fun to an old 4.2.1 Dirty AOKP ROM by Mlaws90 and I went to hospital from the sock. Speed, speed, speed, real DEEP SLEEP and a lot of free memory. I personally never going to upgrade my Nexus 7 again. I strongly believe that newer versions are for latest powerful hardware.

I´ve surrendered to the upgrade temptation, once again.

After several weeks of CM10.2.1 without any OC (F-Kernel 102MHz to 1.3GHz) running smooth and good battery life, I installed Rastapop 5.1 with Data and Cache being F2F. And after a week, if it isn't as good as JB4.3, it´s better.

No FC, no reboots, nothing and good battery life. I didn't install the resources hogs Facebook and LinkedIn. I get notifications through email and thats fine by me.

Antutu got from 21-thousand-something (4.3) to 19-thousand-something (5.1), but in real use experience, including gaming, I cannot tel the difference. And I see no need to OC, but I recon it depends on the games used.

Overall, putting aside the up-to-date factor, it perhaps got a tiny bit more smooth. And i did too used to think this new 5.1 release was targeted to the most performance and recent equipments. But at least my Grouper. is doing just fine after a week.

Loved my N7 2012 32GB, but got tired of trying to get it to run reliably and with decent performance using Lollipop. Going back to KK was no longer an option as I wanted to have a consistent interface across all my Android devices. A week ago I bought a "Manufacturer Refurbished" N7 2013 32GB and installed the latest image of LP 5.1.0 using Wug's Toolkit. I restored all the 3rd party apps I had on the N7 2012 on the 2013 and the difference on overall performance of all the apps is like night and day. Faster CPU, better graphics, faster WiFi and compatible with the current release of LP. Not to mention the additional features one gets with the 2nd Gen N7. Wireless charging being one of my favorites. I bought a used Nokia DT-900 wireless charging pad for $20. Now I just place my refurb. N7 2013 (still in its Moko case) on top of it to charge it. No more fiddling in the dark with the USB cable and port after I'm done reading. Streaming 1080p HD content with Kodi and youtube is another plus. I believe the N7 2013 seats in a sweet spot as it relates to form factor, performance and price. I borrowed a N9 for a couple days, but I didn't like the form factor and I could not justify the price. So, if you have ~$200 to spare, get a"Manufacturer Refurbished" N7 2013 32GB "with" a wireless charger and you won't look back. If you want a 16GB you will need less $. Hopefully, I'll be able to sell the N7 2012 and recup a couple bucks.

I have just started using a Nexus 7 and it's a 2012 version.

I would like to say Lollipop is terrible on it. Keeps freezing up to many darn google standard apps now. It seems like Google want to force everyone to make Google the center of their universe. This coming from someone who first stated with Android with it came out on the HTC EVO! Loved it but battery sucked and half the apps in the app store don't even work on all products. That was pretty much the reason I transferred over to Apple

Maybe I will try Android fully again when the next Galaxy Tab comes out. But until them I will be sticking my Nexus 7 on KitKat version of cyanogenmod 10.2.

I have tried the F@FS wipe and everything and anytime I go to Lollipop everything freezes up.

It is my biggest issues with Android to many different manufactures even if you but like a HTC EVO when they first came out versions that were released 6 months later used different part and they never work the same.

I never wanted to go to Apple, but once I switch to Apple it was nice to know every year a OS Upgrade comes out, it will automatically work for your device. Right now they are on iOS 8.3 and even iPhone 4S are still able to upgrade the OS.

But anyways, I feel sticking away from Lollipop for Nexus 7's are the best bet cause Lollipop is more geared to the higher performance devices coming out today. It's sad how something that is only 3 years old is pretty much considered junk. I have looked trying to sell my Nexus 7 and the most anyone will even give me is $8.00

I'm using the same setup and what I did is:

-flash the factory image via fastboot

-flash the TWRP image (available on the official website or here in the themes&apps section)

-format /data to f2fs in TWRP

-flash franco.kernel r82 in TWRP

You should be good :)

[Nexus 7 Q&A, Help & Troubleshooting] cptsashimi:
F2FS mainly helps by increasing write speeds and system isn't written to plus F2FS takes up more space than ext4, which can hurt you on grouper because we don't have an over abundance of system space.
[Nexus 7 Q&A, Help & Troubleshooting] gunnerhk:
I liked lollipop with Franco/F2FS in the beginning, but it started to lag terribly after a while.

Everything I did resulted in "app is not responding. Wait or Close" message.

So like other people, I clean installed CM10.2.1.

OMG the SPEEEEED!

I can now use the tablet even when there is something downloading in the background.

Seriously, I wouldn't be surprised if google/asus is slowing down nexus 7 on purpose so we buy another tablet.
[Nexus 7 Q&A, Help & Troubleshooting] fe98:
Pretty much followed the same path as you (Franco/F2FS - serious lag, then went to CM10.2.1). Tablet's working fine (for now), will see in a few days time if that changes.

[Nexus 7 Q&A, Help & Troubleshooting] zinko_pt:
Just wanted to share my updates:

1 - sorry for the misinformation, but I have rastapop only, no tricks, no 3rd party kernels. So this means no F2FS.

2 - I've not done any tweak in developer tools or any other place.

3 - I've updated Rastapop to 5.1.1 and it seems a bit even more smooth. With some apps in recents it still doesn't show any lag. Occasionally it shows when loading web pages (chrome), but it always did as long as I remember.

4 - Still I don´t see any reason to OC: pacific front and RR3 don´t have a single lag, except for some loading tasks while doing animation, which is normal. And sometimes when I had the CM10.2.1+F-kernel I experienced a few during game-play, which is worst than LP.

5 - I´m not here to praise anyone's work in development, but it puzzles me the reports of people having lag issues with LP, since I don't have any and I haven't made any tweak or change.

To recap my findings, after my own (limited) experience:

1 - No Facebook or Linkedin apps. At least the official ones.

2 - No F2FS . Somehow, in the pursuit of more performance with system format and 3rd party kernel, performance is decreased.

3 - No OC, since battery drain will occur and LP battery performance improvements will be useless.

4 - No 3rd party lauchers- although I like very much Nova, it just seems OK as it is. The only thing I've missed in official ROM was battery % and latest Rastapop gives me that. Probably as cm-12.1-20150430 would, I don´t know as I didn't test it.
[Nexus 7 Q&A, Help & Troubleshooting] Salty Wagyu:
Went to try out what others did in this thread, installing stock Lollipop on system as ext4 while leaving other partitions as F2FS. I changed System to EXT 4 in TWRP, went into fastboot to flash Lollipop 5.1.1 system.img and boot.img, and it's been showing the loading animation for the last 20 minutes now. What am I missing?
[Nexus 7 Q&A, Help & Troubleshooting] Fobos531:
update to 5.1.1. using flash-all script in the factory image folder. then, go to recovery, and change /data and /cache to F2FS. flash a F2FS compatible kernel like Franco kernel r82 and thats it. It should boot without a problem within 15 min.

I wouldn't doubt it. Backfired for Google in my case since I went and got a Tab 4 instead.:D
[Nexus 7 Q&A, Help & Troubleshooting] iolinux333:
Backfired even more over here as I picked up an iPad Mini 2 to complement the iPhones and iPod Touch I picked up when I was fed up with no updates for Android on my phones. I'm pretty much android free at this point, and after two years of using iOS and Android side by side, and watching the painful crashing and burning of the once beautiful promise of Android, I have no regrets.

Google really screwed the pooch with the Android update model. They completely blew it - even with their own freaking devices.

edit to add: I'm still keeping the Nexus 7 around though, just to see if Google ever gets their **** straight.
[Nexus 7 Q&A, Help & Troubleshooting] Miami_Son:
I think it was more a problem with the carriers than Google. They had to mess with the OS and make it their own with bloatware and schemes to prevent updates that weren't "official." In the case of my older N7 Google messed up by allowing auto updating of a device that is clearly not capable hardware-wise of running the latest versions of Android. They should have cut it off from that or provided a simple way for me to go back. I love my new Tab 4 8", though.:laugh:

Updated with 5.1.1 OTA few hours ago and it works much better. I got three users and there is no more LAG when switching between them. Speed is like on kitkat but animations are prettier.
[Nexus 7 Q&A, Help & Troubleshooting] RusherDude:
Updated to 5.1.1. The tablet now flies, faster than KitKat and any JellyBean version ever.

Also battery seems to last longer than ever o_O after nearly 3 years..
[Nexus 7 Q&A, Help & Troubleshooting] killerfrank:
I agree. Seems much quicker than even kitkat.
[Nexus 7 Q&A, Help & Troubleshooting] barrack1:
The kitkat update for the Nexus 7 wasn't too bad I think but the ota lollipop (5.0) from google update totally killed the tablet with lots of lag, later 5.1 stock ota updates didn't fix the problem. Doing a factory reset didn't help much. I should've cleared the cache/dalvik first but opted to install CM12.1 nightly (and wipe the cache/system,/data) which restored the Nexus7 to a usable state. But I think and I'm not sure that the performance is still a little slower than stock Jellybean/Kitkat.

Right now on CM12.1 nightly, opening youtube takes 4 secs (uncached) to completely load and the search bar to be usable, browser takes 3 secs. Battery life seems to be lower ~5.5hr ost light browsing, videos, no gaming.
[Nexus 7 Q&A, Help & Troubleshooting] iBolski:
I completely agree. Each LP release for this device has been a disappointment. I've done full factory resets, etc, but eventually, performance degrades to the point of the tablet freezing and I have to reboot (and even that sometimes is a chore to make happen with the "3-finger" salute).

But, once I got back to KK, performance and stability returns. Not sure how much could be apps that aren't written correctly under LP, but those same apps on my LG G3 running LP have no issues. I think it's just that the 2012 Nexus 7 is just too old for LP.

So, I'm back to KK and that's where I'll stay with my N7.
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
I honestly think you either have a defective device, have not tried F2FS file systems, or probably don't know enough about your tablet or android to flash or work it properly.

For instance why I think you don't know very much - there is no "three finger salute" necessary to hard reboot the nexus 7. You can just hold the power button with one finger for approx 20 seconds. I will leave the insulting jokes about that to someone else.
[Nexus 7 Q&A, Help & Troubleshooting] dookie23:
updated to 5.1.1

I just updated my N7 with Android 5.1.1. I find the performance is more or less the same as 5.1 but it's definitely better than 5.0.x. Also, there seems to be some more animation added in this release.

I think KK is still slightly faster, if I remember correctly. But at this point, LP 5.1.1 is good enough for daily use and I'm going to stick with that.
[Nexus 7 Q&A, Help & Troubleshooting] iolinux333:
I'm glad to see good news in the 5.1.1 reports and look forward to the OTA when it arrives on my N7.

I still believe Google needs to fix their Android update model to be at least as good as how MS and Apple approach it.

They ought to be able to do even better though IMO.

Android is Linux, and Linux distros run on ANYTHING.

It's time for Google to let Android run on ANYTHING, whenever the user geeks like it. Going between versions should be no more difficult than my switching from ubuntu to mint.

[Nexus 7 Q&A, Help & Troubleshooting] barrack1:
Users don't have to know anything about their device since update is done through OTA . And they shouldn't have to convert their file systems to f2fs just to enjoy acceptable performance.

After trying out a clean install of CM12.1 nightly without f2fs I would say that 5.1.x is slightly slower than kitkat for apps to start up and slower to load pages in browsers etc. Maybe clearing out the dalvik cache made all the difference, and could explain why some users report 5.1 being faster than kitkat, which I don't think its possible but only feels that way because the cache/dalvik cache was messed up in kitkat before. I'm now on slimrom 4.4 (ext4 file system) and its slightly faster than CM12.1 for apps to load and snappier overall.
[Nexus 7 Q&A, Help & Troubleshooting] zinko_pt:
Somehow I do feel 5.1.1 Ext4 a bit faster than 4.4 F2F. There are occasional lags, yes as I had with 4.4.

For example, opening recent apps and closing them feels faster. But getting back to home screen after clearing those recent apps, sometimes, despite the number of recent apps, takes a good 3 seconds.

All in all 5.1.1, for me, is a milestone. Not the best probably, but overall very much on par, loosing in some areas and gaining in others.

5.0 and 5.1 are as Vista was for Windows: should never be launched.

To quote Dr Cox from when scrubs was acceptable to watch, "WRONG ,WRONG WORNG WRONG, WRONG".

If youre going to complain about an out of cycle device (which even the 2013 N7 is now, get used to it) then you first must have a working knowledge of the device and have taken the proper steps to mitigate your issue.

Otherwise we might as well go buy apple products, which if you don't understand the workings of your device might actually be better suited to you. That's what they are for, ignorant users. I use the word ignorant as defined in Webster's dictionary.

5.1.1 performance is a homerun

this is the lollipop performance thread right...I had to step in here and give major props to the latest update 5.1.1 on my N7 2012 WiFi. This device suddenly went into fifth gear seriously it never felt this responsive. Major difference to 5.1 whatever Google did worked.

long story details: no I didn't do factory reset, never done one actually. while on 5.1 got the notification that 5.1.1 was downloaded and ready to install. I'd installed custom recovery and rooted so I knew it wouldn't work to install the update like that, but decided to try anyway. I flashed back to stock recovery rebooted said OK to install and it failed (I should have unrooted but pretty sure it would have failed even then, we know lollipop doesn't like any messing around).

so I fastboot flashed original 5.1 system, downloaded and adb sideloaded the 5.1.1 update, booted twrp recovery, deleted a system app to create some space in System partition, flashed SuperSU 2.46 zip, hit the clear cache/dalvik option, and got out. Apps updating screen took a while, then 5.1.1 appeared and seemed laggy for the first like five minutes. I got busy granting root permissions, by the time I went back to Settings things were popping. Now everything is happening much faster than I remember in a long while, and I've had this device since early Jelly Bean.

Anyway, thanks Google for 5.1.1 on Nexus 7 2012 WiFi.
