unresponsive touch screen in a brand new phone JIAKE G910
I have the same phone for about 3 days. Today, after connecting to USB for several hours to fully charge the phone, the touch screen is suddenly totally unresponsive. I had to disconnect the battery to turn it off. I boot up in recovery mode and did a factory reset, and after power up I got back the factory default wall paper, "the balloons" which means that factory reset was done, but touch screen is still totally unresponsive. I power cycled several times thereafter but could not get the touch screen to respond again. Is this expected for a cheap phone from China? I could not believe the touch screen lasted only one day for a brand new phone. I would appreciate any help or info to get the touch screen to respond again.
Thank you in advance for any pointers to fix this problem.
