I have the 2012 N7. In the past few weeks the performance has deteriorated to where I can hardly use it at times. It's very slow to open apps, the keyboard can be slow to respond, and at times when updating apps, the estimated time is over an hour to download rather than just a few seconds. In addition, it's started taking a long time to recharge. I mentioned that on one of the other threads. I keep the cache cleared using 1 Tap Cleaner, but last night I cleared the cache partition after seeing recommendations here. I was also right at just 3gb free, so I deleted some video and music files and now have mover 5gb free. Performance improves some if I work from Airplane Mode, but that is only a workaround if I'm playing a game. Otherwise I need to be connected. It's taking between 5-10 minutes to reboot and regain control of the device. Anytime it tries to download updates, sync mail etc., it's almost unresponsive until those processes are completed. So ... what's my next step in figuring out this device? It's run really well until the past few weeks. I don't know if it's related to the most recent Android update, but the tablet started getting really bad about that time.
