Today I picked up my tablet & it would NOT start even though I knew it was "almost" fully charged - I plugged it in & was able to get it booted, after which & confirming an 85% charge, I unplugged unit --- although it did show I was connected to my wi-fi I was still unable to connect to the Google Play Store & my Gmail --- after repeated tried to the Play store, I would receive a no connection messge each time ------- I eventually found a forum on connection fixes to try - resetting Play Store cache & also suggested to check my Time & Date settings -- when I did lo & behold for whatever reasons it was way off - today is Dec 3, 2013 at a time of about 3 pm - the device Time & Date was somehow set at Jan 8, 2000 & time was off as well -- after resetting to the correct Time & Date, all my problems were automatically fixed ---------------- SO, my question is if, anyone else had this problem, have you found what caused this isssue --------- I did contact samsung as well in case it might a hardware isssue they might be aware of this problem
