I just acquired another Note 3, except this time on Verizon. Everything seemed to be working fine. I got home, did a factory reset (because the CSR skipped a bunch of stuff) and got everything set up the way I like it. Installed a few of my favorite apps (Snapchat, Spotify, Clash of Clans) and turned off all the Amazon and Verizon bloat.
About an hour after I got home I had my screen freeze. There was a few static lines going across the screen and then the device rebooted and returned to normal. No biggie. Then I played Clash of Clans for a little bit and the same thing happened. Sigh. This time it didn't restart itself, so I pulled the battery and noticed the battery cover wasn't fastened completely at the store. This made me question if that was the cause, but usually stuff like that happens from software issues. I left the battery out for a few minutes and threw it back in.
There was a couple more times it happened, but really no need to go into detail. Now I'm just sitting here typing this out hoping it doesn't happen again.
Any ideas to what might be causing this? I don't use any apps not tested on Kitkat, and am not rooted etc. I'd hate to make another trip to the store to swap it out. Oh, and I also disabled WiFi scanning, and that didn't seem to fix the issue.
