The original Nexus 7 filesystem drivers weren't issuing TRIM commands when deleting files, so write performance became much slower (in some cases, <1MB/s). LagFix is a rooted app to fix it, and there are alternatives for non-rooted devices as well.

My solution (which includes some steps described ITA) after struggling for while: 1) get rid of multiple users 2) free up a lot of space 3) run ForeverGone.

#1 was a step backwards, but so was horrible performance. Now things are running smoothly.

I noticed my Nexus 7 getting very slow, found this same information, and ran ForeverGone. There was no noticeable improvement. I then did a factory reset. It may have been a bit snappier at first, but within a couple days it was slow again.

Mostly, I noticed jerkiness and lag scrolling web pages. I'm not sure what I'll do now. Between that and a huge stuck pixel that won't go away, I regret buying this Nexus 7, which was my second one after the screen broke on my first.

I got a dirt cheap clone (I don't remember how much exactly ) from a Chinese reseller from Amazon UK and the screen was crap ^shudder^ and the touchscreen had a glitch ^double shudder^ but it was Android and it was reasonably quick.

These things you really need to try before you buy.

There's another thread here about the potential slowdown issue. Same'll happen to a Mac or PC I reckon after a while. I've not noticed it. When you think about it Android tablets are pretty new so they haven't been used to their full extent, nor to the end of their lifespan.

Aye, the cheap one is fine for the specific purpose (testing those issues in the stock android browser an a cheap device) but would be infuriatingly slow for my day-to-day use of the Nexus 7. The slowdown I've noticed is only really when I'm asking it to do more than one thing at once (usually updating apps while browsing heavy pages or stating other apps) which is fairly rare anyway so I'm not particularly concerned ATM.
