Wonderful little device with great display. Thin, light with a rubberized shell. nice to hold and you can hol it all day long.
Problem is that many HTCs, and this phone is no different, are plagued with a random and recurring boot-loop. You cannot remove he battery either. Soooo ... You're in he middle of an important call and the phone randomly reboots. You're sleeping and he phone randomly reboots ( and when it does, it plays it's little tube and wakes you). You're having dinner and the phone is 10 feet away and it reboots. And, when it does, it does so over and over and over (like 7 times or so).
Solution seems to be a hard reset, with SIM removed (wipes your data, newly added apps, data settings and personalizations). However, this only gives you about 16 hours of peace ... MAX.
So, if you dont want to be a slave to your phone and you value reliable communications ... my latest solution is to return it and exchange it for a good old reliable Samsung.
