After tablet went dead yesterday, finally got it charged and rebooted. Problems: 1. Date shows Jan 1 2000. Won't update 2. Gmail won't update 3. Google calendar won't update. 4. Playstore shows "No Connection, retry" I checked my account settings--all good. I can connect to internet OK. Sync is on but nothing connected to google works at all. I was going to delete the google account on the device and re-add the account but can't see where to do it. Tablet is kinda crippled right now. Looks like it's all connected to google somehow. Playstore and everything works fine on my Nexus Phone. Just can't get this to work. No way to do a battery pull. Edit: I went in and manually set date and time in settings. Playstore, Google calendar & tasks, gmail all started back to syncing properly. Manually setting date and time is either a guarded secret I stumbled upon, or perhaps just a coincidence. Whichever--things are working for the moment.
