my fiancee's G2 screen went out last night, it looked like it shattered from the inside because there was a 1 1/2 inch crack under the glass. she says it was working perfectly fine, put it in her purse and a few mins later it wouldnt turn on. she didnt drop it or hit it against anything so i have no idea what happened. exchanged it at radio shack today (only had it 10 days) and the guy said it had to have been from a heavy blow. i know she is capable of abusing phones but i believe that she didnt this time. her purse is small so nothing big could have slammed against it. so i'm thinking, she's been using my charger (nexus one) and i know the batteries are different. could that have been the cause? something with the amount of electric currents? the only other thing i can think of is how it kinda heats up when its being used. her phone has a hard case so maybe the heat doesnt escape and it just builds up inside. i dont know, those are my only theories. any other possibilities?
