I had to return my 1st one because the ear speaker was defective. My 2nd one worked great up until last week. I was charging it (phone was on) and went to take it off the charger and the back of the phone was hot and it had shut off. The phone wouldn't turn on so I popped the battery out, put it back in and it started. It's been kinda weird acting since. This morning I was charging it and it did the same thing so I gotta bring it back today. My 30 days are up on the 26th so hopefully I don't have any more problems.
