2012 N7. Unbearable lag since 5.0. Like a brand new tablet on 5.1.1. Anyone else?

Yes, I was a bit cautious to start shouting from the hills at first but after a good few days usage I feel I can agree that performance is much better now. Very pleasantly surprised.

I wouldn't go as far as saying it is completely fixed and back to how it was when it was brand new, but at least the thing is usable now.

5.0 was horrific; almost threw it out the window.

5.0.1 was a bit better.

5.1 was a big improvement.

5.1.1 does feel close to new again, but I am not a good barometer of battery life; it stays in the dock quite a bit.

2012 N7 only OTA updates

Better than f2fs KitKat?

I find 5.1.1 much better than 5.0, but not "like a brad new tablet" better.

Back to its former glory. So far so good. Will keep people posted

Yes, it responds a whole lot better now (2012 N7 32GB as well) - where before I timed up to ten seconds before a response. After most earlier OTA's the tablet did perform better initially, but soon went south anyway. The improved performance seems to stick but I'll be certain in a week or so.

I sideloaded 5.1.1 on my 16G and is back to it's former self. There are a couple of random app crashes that may be due to not erasing the data partition. But really, it become useful again. BTW, I am typing this on it!

Same here so far, but just getting started with it. Fingers crossed...

happened to me... then 3 weeks later it bricked at the google logo ..keeps rebooting

This is sweet news. Will update today!

Mine still lags badly with 5.1.1. Setting the background process limit to 2 in developer options has helped, but it's not ideal.

I've got the 2013 N7, but same thing though. 5.0 was bad and 5.1 fixed it. Just got 5.1.1 last night so I haven't had a chance to play with it.

Same here. I was getting rather annoyed with that system update notice in the taskbar though. I put off even the 4.4.4 update for months.

My 32 gig 2012 3g is going strong on just stock and ota updates. Had a scare one day but so far so good as of today!

I just updated mine a couple of days ago. Speed is much better but I think I'm down on battery life. It was down 25% last night after being off then charger for 15 hrs and 1:45 of screen time.

Last time I updated to lollipop my N7 became near unusable. Sluggish performance and crashes were more common than mosquitoes on a swamp.

I finally learned how to get it back to kitkat and it's back to the tablet I loved back in 2012. I'm not really sure I want to go through the process once again if 5.1.1 doesn't work as intended.

using chrome or kindle app still locks mine up

If a flash seems to boost you, it was probably trim not running or something.

Here are my "real life metrics":

Scenario 1:

1. Install "reddit is fun"
2. Go to r/videos
3. Tap a youtube link and see how long it takes to open youtube

Scenario 2:

1. gmail yourself a link
2. tap the link from inside gmail, thereby opening chrome
3. See how long chrome takes to open

Scenario 3:

1. Open Chrome
2. Tap in the URL bar to start typing a search pattern
3. See how long or if it gives you a wait/quit prompt it takes so long

All of these are unacceptable to me on 5.x (even with F2FS) on the 2012.

1. Downgrade to 4.2.2.
2. Install m-kernel mr1. (this step is optional, it has a better io scheduler for our tablet though)
3. root, install adblock plus (our tablet are too slow for ads, its a turbo for us)
4. Open chrome for the first time and DISABLE CHROME SYNC

I'm in the 4.2.2 club, no F2FS Kitkat needed.

Everytime someone does a fresh install they post something like this. The os isn't making a difference, in a few days it will be it's slug self again

Yeah, my 2012 N7 is IMO, faster than brand new.

But there are reports of serious problems with others.

Has Google simply just given up on quality control testing?
