Hey everyone, today I've run into a very strange behavior with my phone, where the screen will flicker and then it will shut off (not do the typical reboot if the OS simply crashes). Further complicating things is that the battery drains seemingly too fast now compared to a few days ago. The phone isn't even charging anymore, which is of big concern. Any things I can do myself to diagnose this before I take it back to the Verizon store tomorrow (hopefully they are open)?
