[Guide] How to fix 4.2 lag

[TheAtheistReverend]

I have an unrooted Nexus 7 running 4.2 and a lot of the time it is buttery smooth, except at a random time, usually in front of someone else, when I need to do something RIGHT NOW, and then the Nexus 7 turns into a rebellious teenager. Lagging and freezing badly.

The only thing I have not tried is a wipe. I just don't want to lose saved games and data, and I know of no way to back then up without being rooted.

Any advice on backing up saved game data so I can wipe without fear?

Because really, it's this or back to 4.1.

Have you looked at My Backup?

Otherwise root that sucka! It is a piece of cake.

Yes it won't backup app data without root.

And of course you can't root without unlocking, so I just bit the bullet and did so. No lag so far.... But it's early.

Glad you dove in for root! Makes life so much easier. Now get adfree from the play store, and you've covered the biggest reason why I root. I'm still running stock rooted because I don't need any more than this.

 

[rmagruder]

I take it ad free removes ads from apps? Ugh. Dude, I hate ads like everyone else, but if they are the only way a developer gets revenue for their work, I will tolerate them.

I should also note, my Samsung Galaxy Nexus on Verizon has been rooted and ROM'ed so much it isn't funny. But then that's also because Verizon leaves us to die so often. I was hoping it wouldn't be necessary on the Nexus 7. Oh well....

It's multi-user

Dear All,

My N7 lagged after 4.2 update. I disabled Currents and it was better but still lagged. I just removed multi-user and I am back to 4.1.2 smoothness. It lookes like the multi-user is the problem. Google would probably fix this in the next minor update.

Did you disable the service or do you mean you had multiple users so you removed them?

Bobby,

I removed my guest user and now I'm back to just one user. Now, everything is butter smooth just like 4.1.2. Therefore, one should only have one user and disable Google Currents' sync function.

OK cool. Haven't ever had a second user. Was hoping there was a way to shut down the multi user service which would restore it to majesty.

too many reading or writing tasks in the background ?

Hello. I haven't read the whole thread yet, but for SOME people still experiencing lag, this page may be interesting :
http://www.anandtech.com/show/6073/the-google-nexus-7-review/6

If you have many reading/writing tasks in the background, this could explain things (µtorrent etc)

 

[brakke97]

This fix is actually pretty well found! Good job, bro! :victory:
No more lag for me! :good:

 

[madphone]

for me it didn't help at all. the biggest lag is when unlocking the device in another oriantation as it was before unlocking. it takes up to 5 seconds to rotate and get responsive. can anyone point in the right direction? maybe there is a thread i have missed?

 

[CheesyNutz]

holy flip no more lag !!

 

[Adinaky]

Glad I found this thread, no more lag for me. Thanks!

 

[borrowedchief]

I still lag. I was about to factory reset, but saw a couple other users did that and it didn't help. Hope it gets patched up soon.

Forever Gone

Forever gone is the solution after doing the above I downloaded forever gone ran it and BAM its smooth as budda!

from my SGS3 while my nexus 7 rests

I've been running Forever Gone for weeks now, whenever I go below 3G (often down to around 1G free ) on my 32G Nex7, and it's been working fine. Whatever lag I do experience vanishes every time so far, and with so little space left it really doesn't take much time to run.

This may sound silly, but if I disable Bluetooth, it solves a lot of lag issues.
The Bluetooth in 4.2 has it's problems. Never thought it would affect performance.
I might look into that.

Does the android 4.2 on the nexus 7 with mobile data version lag out of the box?

I'm getting one of those by new yr from usa to use in india and am afraid if something goes wrong

 

[kwabby]

I have also notice, if you keep your WiFi on during sleep there is no lag on the lock screen.



Nexus 4 & 7
