I've tried nearly every version of the official Nexus nakasi and Cyanogenmod grouper ROMs for this device and I have come to the conclusion that my Nexus 7 2012 32 GB device has the faulty memory that degrades over time.
I can flash the device and optimize the living crap out of it with any number of optimization tools, even Trim (fstrim), but after two or three days I'm back to horribly lagging performance. Even going back to Jelly Bean, Kit Kat, even earlier to Gingerbread, it doesn't matter, it's just bad.
So, if you are offered a 32 GB Nexus 7 device from 2012 for a good price, consider it closely, since it might not be what you wanted.
