The best price with the specifications and after watching various reviews I buy the product but.
I kept it on my working desk and it blinked light, is aw a sudden screen on on my phone and it was hanged with no touch response and fingerprint sensor also not working. Then I thought of restarting the phone, I pressed the power key for 3 secs and choose to restart device.
The piece went off and never came back. Then I tried turning it on manually by pressing power key, it responded with vibration but small vibrate and no screen, this continued for 10-20 mins then it stopped responding that vibration too. I kept it in my bag and walked off home after filing for replacement with amazon online for device. As soon as I came home removed sims and sd card from slot and tried restarting it but all in vein no response.
