If I do not restart my phone at least once a day, notifications will stop working. I'll stop getting Gmail notifications, GroupMe notifications, Facebook notifications, WhatsApp notifications and more. Also, if I try to start Gtalk, it will briefly open and then immediately close and return me to my home screen. I had this issue with the first phone I got and they sent me a new one and now I'm having the same issue again. Has anyone had the same issue or does anyone know how to fix this?
