Lately my razr maxx has a problem with the sd card. Every so often my phone will say "sd card unexpectedly removed" after this message appears the phone will shut itself off. It has become very frustrating, the resetting has caused it to start draining the battery like crazy. Like today I've had the phone on and it's at 70% under 2hrs of screen time and it's only been on for 4 hours. Before the resetting started my phone would still be at 90% with the same usage.
