Hi everyone... I just recently bought a ZTE Warp Sequent with Boost Mobile. This is my first smart phone but I know enough to know it should not be doing what it is doing. Every once and while my screen will start to flash and blink and freezes up. The only way to get it to go back to normal is to pull the back off and pull the battery. I know this can not be good for the phone but I don't know what else to do. I have downloaded Norton and the Web Dr. Apps to help protect me but it doesnt seem to be helping. Should I just take it back to Best Buy? Is this something I did or is it a device defect? Any replies or ideas would be much appreciated. Thanks!!
