I have had my Note 3 since launch day and have had no reboot or locking up issues till now. I installed kitkat and then my phone started locking up in random apps and then just reboots. It seems to happen 4 or 5 times a day since the install. I tried to wipe the cache, but that didn't help. I read a lot of posts that said to do a complete wipe of the phone after an update, so I decided to try that, but that didn't seem to make any difference either. It doesn't seem to be any certain app either. It just locks up for no reason and then reboots. Its driving me nuts and I'm not sure what else to try. Has anybody else had this issue? Thanks!
