Q: Randon reboots with SystemMemoryResets in error log

Out of the clear blue sky my iPhone is rebooting by it self at least once or twice a day. In the diag logs it says  multiple systemmemoryresets.  I'm getting rather concerned because I never have any until just recently.

I have a zag clear glass screen protector or I paid $40 for I'm going to lose that if they exchange the phone, will i.
