I was an early adopter of the HTC Evo, and had my first phone for a year and a half with zero problems...until I cracked (destroyed) the screen accidently. $100 later and I had another one sent through insurance. Well after a week or two it started to randomly shut off. I've read threads here about the Evo rebooting, but mine does not do that, I just pick it up off my desk or out of my pocket and sometimes it isn't on. It's only happening a couple of times a day, but who knows how long the phone is off...I don't notice until I realize I haven't had a call for an hour or so. I took it to the Sprint store, they cleared the cache, I did a hard reset and they sent me on my way. A few days later it started again, so back to the Sprint store. They got me a new Evo in 2 days, and of course it's now happening on this phone too! So I'm on my 3rd Evo, and the last 2 they have given me (one through Assurance and the other through Sprint Store) are both randomly shutting off. Anybody have this problem, or think there may be a solution. It may have happened after my last software update...but I have no way to prove it. Any ideas? Take it back? Keep cycling through Evo's until I get one that works? It's turning into a pain in the rear.
