So this is kind of a weird thing that just started happening lately. My friend and I have both had the Triumph since it came out. No problems whatsoever until about 2 weeks ago my friend's phone started having this problem and now about 3 days ago, my phone is having the same problem. The problem is the phone will be on and working fine. Then if I let it sit for a while with the screen off, the screen will not turn on again. Even calling the phone does not make the screen turn back on. The only solution is to pull the battery. It only seems to happen maybe once or twice a day, which isn't very often, but it's very annoying. I also thought it was odd that the same exact problem happened to my friend's phone and mine within a couple weeks of each other which makes me think it could be some sort of software issue. Is anybody else having this same problem. If so anyone have any solutions? Any advice would be greatly appreciated.
