Hello there..
Couple of days ago I received a notification to upgrade to Kitkat 4.4.2 and I did upgrade. Since then the 4G icon sporadically appears. Unless I leave my phone with WiFi enabled, it reboots on it's own approx every couple of hours. If I disable WIFI, I can not connect to play store or even access WEB pages. Verizon tells me to reset to factory and then try to revive the phone. I have approx 700+ apps and data on internal as well as external SD card and cannot afford to take that action. Also with this upgrade I am not able to write to the external SD card which I was able to do in past.
Is there any solution? This sounds like finger pointing - Verizon tells me that the upgrade came from Samsung not from them? Is this true?
