Well with the exception of voice quality the only other issue I see with this phone is the random power cycling (Once or twice every 12 to 18 hours), no bluetooth file transfer that I have experience with the phone. I am about 3 weeks into owning a Titan and tomorrow I decide if I am going to keep it or get a replacement or reverse my Upgrade.
Dont forget about the slow data speeds. My Samsung Focus was faster than this phone even though that one was 3g.
One of the three I tried died a power-cycling death within hours of coming out of the box. Did not notice on the other two, but had each one for about 10 days before giving up on TITAN altogether.
Removing ALL HTC software stopped the Power-Cycling for me. It used to happen 5-6 times a day before.
So get rid of all HTC software (HUB, compass, anything and everything)
My HTC HD7 had the same rebooting problem, so it's most likely an HTC problem
Are all phones affected by the power cycling?
