Hello , Please I got My Desire Z A week ago , and it'a amazing , but the other day i left it in the glove box in the car , when i returned i was turned off by itself , and when the battery was still full when i turned it on again , and the same thing happened again before two days when i went to sleep and the phone is charging , i woke up to found it Off again , but since then it didn't happen again , so i need to check if this happened with any of you Guys or heard about it !! Thanks So Much
