Just a short update on this problem. Since the only thing that changed was the battery was fully charged for the first time. I decided to let it run down despite the touch screen being unresponsible. Guess what; the next morning when I checked it, the screen is still unresponsive but when I disconnected the battery to turn it off and reconnected battery to power it back up. The touch screen is now WORKING normally. Battery level reads 39%. There seemed to be a hardware issue that caused the touch screen to not work when the battery voltage is at the fully charged value around 4.2 volt. I'm charging it up again to see what happens.
The second issue with this phone is the ad claimed that this phone has GPS sensor but Google map says that "GPS is disabled" and I have not found a way to enable it.

2nd Update
I charged it up to 100% using an USB power supply instead of the USB interface from the laptop and did not see the unresponsive touch screen problem again so battery voltage is probably not the problem. Perhaps the interaction between the phone and laptop over USB is the culprit. I did not install the driver for the phone because I was using the USB from the laptop only for charging. Anyway touch screen seemed to work normally but GPS sensor is not available, as in not installed in hardware.
