ZTE Zmax Pro: black screen/glowing home button, won't even vibrate
I have a ZTE Zmax Pro. This is the second phone of this exact model that I've had in the last 4 months, and they both have had the EXACT same flaw. I returned the last one because I thought it was just some manufacturing issue with that particular phone... apparently not.
The phone has randomly decided that it will not unlock or turn on. There is no red light, there is no FTM screen, and there is no android system recovery screen. I can't find anyone with this exact problem anywhere, but it's happened to me twice with two different phones! The screen is completely black aside from the slowly pulsating home button. I've tried charging it regularly, charging it through a computer as suggested, I've tried every single button combination there is, and it won't even so much as vibrate.
I didn't drop it. I keep it far from any moisture. The buttons aren't stuck. The battery was at an 87% charge when the screen went black, and it didn't seem to actually shut down (it looked as though it just locked like normally), so I doubt it's just got a broken charge port like some comments are suggesting.
Please help. I can't afford a third phone. :(
Is this a good question?
