What People Are Saying

Rated 1 out of 5 by from Terrible Touch screen goes off when you touch the back of the phone. Touch screen feels unresponsive sometimes. Hard to tell if it is on silent or not. Struggles to do simple tasks such as open contacts, browse the webs or use apps. Touch screen keypad is difficult to use. Battery life is pretty good.
