phone just cuts off and restarts

[mac901]

ok so i was in chi town enjoying 4g and was amazed by it.but the problem was that while"stock rom also" i was using google maps texting and checking email my phone would just cut off and i would have to cut it back on but before hand it never did this. and once i went backl to 3g it never did that before. not a problem now cause 4g isnt in my area yet. anybody ever had this problem??

I've had the problem a number of times also. I've swapped batteries and it still does it sporatically - maybe once a week, usually when I'm on a phone call!

This is a well known issue. It does it on 3G, 4G, stock Rom, custom roms, you name it. It doesn't matter which Rom you use, or if you are on 3G or 4G... it will reboot randomly. It seems that flash websites will cause this as well as warm battery/phone and weak signal while using data. This is what i have narrowed it down to. Yes it sucks badly and there is no fix that I am aware of. I have flashed every stock and custom Rom available and my evo still has random reboot for no apparent reason. Even with a perfectly cool phone & battery. HTC needs to fix this ASAP!
