Who I have the same questioned this topic

I never had an issue with my Moto z3.  It got water damage and I sent it in for ins. Claim.  I never got any notice it was received but tracking says it was.  They sent a replacement or loaner phone and this one shuts off all the time.  I tried to take photos tonight for my son's first and last homecoming dance and it turned off every time I tried to take a picture.  I got about 5 pictures total out of trying about 15.  I finally gave up.  So disappointed.  Do I need to do some kind of report and tell them this replacement doesn't work?  I can't afford to pay for insurance just to have then give me someone else's cruddy phone!
