Default 4.2 lag

So, since updating to 4.2 my phone has become noticeably slower. Response times on launching apps, returning to home has gotten worse, even the keyboard lags behind when typing fast. Phone is unrooted, stock 4.2. Is there anything I can try to speed things up? Its possible my phone is just bloated with a bunch of stuff.

My first question is if you have turned the phone off since updating? I had some issues with slowness after putting 4.2 on my phone but rebooting seemed to fix it.

If you have rebooted and are still having problems, then bloat would be my guess and that a factory reset would be a good idea.

if the lag continues and you want to stay stock i recommend doing a factory reset.

I did a factory reset, it doesn't help much. I notice the lag mainly with the camera app.

i would still recommend the OP consider doing one. Everyone's mileage varies.

Factory reset isn't going to help. That only clears the data partition. You need to format the system partition and re-flash the system. That will most likely yield better results.

Yes my galaxy nexus is very laggy since upgrading to 4.2. The home screen jerks, the camera app takes ages to load and seems klunky. Google now slows down to about 2 fps sometimes and it takes ages to start listening for speech input. I love the photosphere feature but the new lock screen looks crap. Overall this is a big step back from 4.1.

I got the update on the first day it was available, and I haven't had any problems with slowdowns. Try a factory reset if nothing else will work.

Is there an app that may be taking up memory? If there's a bunch of apps constantly running in the background, it will slow down any phone.

some help to reduce screen jerking is to turn off auto brightness.

Try opening up the Currents app, go into settings (the three dots in the top right) then down to settings then uncheck 'enable background sync'. This seemed to speed things up for me.

I think a read the same article as you. Also quit Currents from running in the all apps list and then do a battery pull for good measure.

I've also turned off Now. It didn't do much for me any way.

By the way, for people who are experiencing this lag, do you have Chrome as your default browser? If so, try this: clear all the defaults for Chrome (Go to Settings > Apps > Chrome > Clear defaults). Then set the bundled browser ("Browser") as the default browser when asked to open links. Does this help clear up some of the lag?

factory reset for sure.
i have clean installed 4.2 a few times now and they are all SUPER smooth...even smoother than 4.1. my only complaint is the "lag" opening the camera from the lock screen and the "lag" when rotating the camera app.
thats it.
factory reset should help out a lot.

Hmm, I don't remember it being laggy, but maybe it was. This is the only place I experience any issues. But it is pretty severe when rotating the camera from landscape to portrait and vice-versa.
