My D3 is getting worse, reboots about every 4 or so days now. It seems to have started after the update. It would reboot once in a while, then once every other week and now it is not even a full week. I really don't want to do a factory reset but I am getting really annoyed (I will end up doing one, just hate that I have to). If it isn't rebooting it gets slow and freezes, I've done many battery pulls lately. I found threads on the web w/similar issues and factory resets don't always seem to help. I am not rooted and (probably) out of warranty, no insurance. Any other sufferers out there?
