May I recommend the HTC 10? Just got mine about a month ago and I reallly love it.
But seriously, if you’ve got one of these explodophones – turn it off and take it back.
I’ve had a battery explode on me and it’s terrifying.
I had an AirCard for my laptop some years back – it plugged into the USB port on my laptop for internet access. I was sitting there one day, and I heard a hissing sound and I couldn’t figure out where it was coming from – I thought it was my soda can at first. Then the case popped open and went flying, and the battery itself went pinwheeling across the coffee table – WITH FLAMES SHOOTING OUT OF IT. It stopped before it hit the carpeting, and was still on fire when I upended a Coke on it.
Had I been anywhere else in the house when it happened, it would have been a full on disaster.
So, really, take the phone back.
