  1. thank you, Drew Debois! I am one of those Nexus 7 2012 ownersand this has been quite a nightmare! My tablet is pretty much UNuseable! The minute I allowed Lollipop 5.0 to download, my tablet has never been the same. Now, Ive totally reformatted my tablet, but of course that just started Lollipop all over again. In addition, Google insists I have Solo Launcher take my tablet over! I really get little choice…you know how in your face Google’s bloatware apps can be!
    So what next?? Looks like I now just have a useless AND slow 7″ tablet!?!? Im planning on taking a ball peen hammer to it…and will NEVER BUY GOOGLE ANYTHING AGAIN!
    I sure appreciate your trying to help, tho! I may gey brave and attempt to take ‘er back to KitKat peior to the ball peen therapy…I will keep you posted! At least I know Im not alone out here with this MESS!
    Have I said how MUCH I HATE GOOGLE YET????

    1. Go in to settings and keep tapping the build number until the tablet tells you that you are a developer. Then press back and in settings
      .you will have a new section “developer options”!!! Get in there and change the settings having to do with animation to off. Also enable force GPU rendering.


  2. Tap Power Down until the “erase or wipe the cache partition” is highlighted.

    Should that be Tap volume down as it my nexus keeps restarting when I Tap Power Down?

  3. I just want to let everyone know that I installed the odex version of the stock 4.4.4 f2fs rom on my nexus 7 and the thing is faster than I could have possibly imagined. It even beats out my moto x. It is kind of weird because this now gives me no reason to upgrade, and now I am probably going to be sending back my shield tablet because this is actually so good that there is no purpose to upgrading to something that is actually quite a bit slower now. Anyways, if anyone needs the links, I can post them, but I just wanted to say that everything is running amazingly on the new f2fs roms, so if you are having an issue with your n7 becoming, slow, just try that.

  4. Sadly this didn’t solve the problem for my Nexus 7 2012. It’s still a slow-moving beast. Should note that I think one of the several Google-issued updates had already tried the cache wiping approach as when I took these steps, the wipe only took a second. But on reboot, just going from portrait to landscape mode took over 2 minutes!

    Seems like Google has really allowed Lollipop to turn this excellent tablet into a doorstop.
