Has anyone else had any performance problems since installing Android 4.2?
I heard a few rumours about problems before I got it and then was frustrated to see that it had indeed slowed to a crawl once installed. Very frustrating, it’s probably worse than my pre- 4.1.2 Android tablet.
Curious to know if anyone else has had an issue, and whether you’ve heard about what might have caused it?
I’ve seen one thread that points the finger at Amazon’s App Store app. I, like others, have noticed that it constantly requests my login details. They’ve found that removing Amazon app store had the effect of restoring their tablet to its old buttery self.
I haven’t tried it yet, of course the downside to this is the loss of any Amazon apps you had installed as the Amazon DRM requires you to have the app store app installed for them to run. I haven’t bought any but I have a fair few “free app of the days” installed!
Hows your N7 post 4.2?November 19, 2012 at 6:09 pm #16444
Intresting I have had no problems at all with the performance of my N7 since the 4.2 upgrade however check out this article from PR by Chris Cook and the comments from its community followers..Guess I’m just one of the lucky ones!November 19, 2012 at 9:48 pm #16549
Wow that’s some list of problems in that comment section, here are a few quotes:
-Wi-Fi drops, very slow network results
-tablet keeps going into hibernation every 1 min
-noticeable lag switching between apps
-Amazon App Store kept making me log in over and over again
-I made a second account for my girlfriend… since then it’s been unusably slow
-I preferred project butter over project stutter
-Whole OS seems slow after the update
-Nexus 7 restarts randomly about 2-4 times per day
-apps cutting out or closing
-Touch sensitivity issues
-battery life decrease
-crashing apps, freezes, and now i have very low available ram
Very wide ranging list of issues and it’s always hard to know which, if any, are directly caused by 4.2.
It does make you wonder what’s going on if so many people are having problems. And why is it just some people?
Someone else posted:
-Sorry guys, mine has been great!!
One guy suggests a fix:
Clearing the system cache seems to have solved all of these issues. Go to settings, click Storage, click Cached Data, click OK to clear the cache. I haven’t had any more problems since I did this.
I’m going to try now…November 20, 2012 at 10:00 am #16862
OK, so today my Nexus 7 is running much better.
So I’m going to recommend the fix above as something that’s worth a try because it seems to have sorted my tablet out – so far at least…
Nexus 7 post Android 4.2 performance fix
Clear the system’s cache:
1. Go to settings
2. Click Storage
3. Click Cached Data
4. click OK to clear the cache.
I then rebooted and found I had my super smooth tablet back – yay! Although Amazon app store is still causing me probs, but I guess that’s down to Amazon to sort out!
Let us know if this works for you?November 20, 2012 at 10:37 am #16880
OMG that worked thanks so much I can breath easy again!!November 20, 2012 at 11:48 am #16918
Yes, I think this has worked, mind you rebooting seemed to help me temporarily too so I’m not getting too excited.
We need an Android 4.2.1 release to sort this mess out properly.November 20, 2012 at 11:53 am #16920
Seems to have worked here too. Was experiencing massive lag but all seems sorted (for) now. Good work.November 20, 2012 at 1:33 pm #16963
Yes, I’ve been having problems, but I thought it was due to JuiceDefender. I’ll definitely do this (as long as it doesn’t clear the scores on Bad Piggies or Plants Vs Zombies otherwise my son & wife will kill me :D)November 20, 2012 at 2:43 pm #16996November 20, 2012 at 6:00 pm #17080
Thank you, its worked for me. I’d forgotten just how fast it was.November 21, 2012 at 1:04 pm #17580
Problem with AOL mail. For new mail, there is a black circle with white cross inside it and an outer black circle against first item. White arrows are coming up from bottom of screen, if you look into it there is an ‘advert’ for Galaxy phone.
On ‘wake-up’ screen where you enter password on a keypad without an outer grid for Nexus 7, why is the hour of time in bold but minutes is not?. It looks stupid
Hope Google undo version 4.2November 21, 2012 at 1:19 pm #17589
I think the clock thing is a stylistic “improvement”, I actually quite like it but not everyone has the same taste!!November 21, 2012 at 1:52 pm #17611
It’s been terrible for me. All your problems and more.
SOOOOO SLOOOOWWWWW. I’m wondering if it’s easy to roll back? I want my buttery smooth experience again.
I cleared the cache from the recovery menu, and it helped for an hour or so. Now having the same issues.
Ugh! :(November 21, 2012 at 9:58 pm #17821
Yep, I think mine has slowed again too, the cache clearing seems to give a temporary boost again though.
With this many people noticing probs Google must be aware of a problem? Surely a 4.2.1 is on the way?
Roll back, I guess you can wipe and install an older image. Probably involve rooting and Roms and outside my own experience (although tempted to go and look into it!)
XDA forums will be a good place to get technical.November 22, 2012 at 2:02 pm #18223
Mine is slower, especially the accelerometer. Had a couple of random reboots, the pattern lock freezes for a few seconds if I get it wrong whereas if I got it wrong before the install I could try again immediately. The screen filter app doesn’t work at all anyore and I had problems bookmarking websites on Boat until I went into the app settings and cleared the cache. I read a couple of posts over on the XDA developers forum which suggested that problems with OTA installs were the cause of all these issues. A few people said that doing a factory reset sorted all the issues out. I haven’t tried that yet, would be a hassle installing everything again – plus would need to make a list first of everything that I have put on my N7 first because as far as I know, there is no way to do this or to backup your files and data without rooting. So, for now I am living with it.
