I am on my second device. ZTE replaced the first one (or did they?) Now, the second unit is doing the same as my first which made me send it in for repairs. While watching a movie, a message will display when the battery runs down. When I insert the battery cable, the projector light begins to flicker in and out until finally fading to black. The sound can still be heard, and if I unplug the battery cable, the picture reappears. Factory reset has been done, apps uninstalled...nothing fixes the problem. Any suggestions other than use it as a paper weight?
