So I'm not a heavy tablet user, but I did manage to snag a Nexus 7 (8GB) for free at a conference a few years ago. I use it (what I feel is lightly) for a few games, RSA soft token, email, some browsing/reading, etc. After upgrading to 5.0.2 it's been a painful beast. I had initially thought that this was likely due just to NEW OS and OLD hardware. However after doing some digging last night I came across a number of suggestions to wipe the cache partition. Instructions can be found here: How to wipe cache partition Nexus 7 or like this .
