My HTC One V got extremely hot all of a sudden and I couldn't touch the screen without burning myself, so I turned it off. It stayed hot for about another hour and then began to cool down. Now, it doesn't turn on and refuses to charge. Any clues on what's wrong?
That's odd. Were you trying to run a graphics intensive game or perhaps too many apps got stuck running in the background and ate up the memory on the phone so it overheated?
It sounds like it damaged the phone internally... I'm not sure if will turn on again at this point.
If you've had it less than a year, take it to a Koodo shop and attempt to make a warranty claim. This is a bit of a grey area; I don't know if it'll be covered, but it's worth a shot.
Otherwise, you could always upgrade your device. The One V is great for just basic talk+text but it lacks raw power to be a daily driver. I would honestly only use it as an emergency backup phone or a loaner.
If Koodo won't cover it under warranty, perhaps they'll help you out with some Tab credits to get a new device? This is at their discretion, and I make no promises (neither do they), so give them a call and see what happens. You've got nothing to lose, really.
