I am thoroughly disgusted with this phone.
Random reboots, random freezes, etc.... today I couldn't even make a call after it froze again. rebooted and it begins randomly dialing the last number dialed. battery pull finally stopped it temporarily.
have hard reset several times with no change. skips during music playback, even after moving mp3's to the phone from memory card.
unfortunately i purchased it used and therefore have no warranty.....now just trying to get rid of it.
my advice.....think long and hard before buying one of these. you may be in for a long period of frustration.
also...i am a tech geek and this is not my first android phone, i know all the tips and tricks. this is just a crappy phone. whether it is caused by the software or hardware i don't know for sure.
