Had the phone a couple months now and I this has happened twice. I reboot every 2-3 days . Phone just went crazy with email notifications sounds. check phone and find all emails are unread. I should have checked the ! message but just swiped them all read and rebooted.

No other observations or anything else worth mentioning. Otherwise everything else is good. Wifi is still a little weak but might even be better to now pick up a hotspot unless im real close.
