Acer Liquid Z220 power charging interference

Hello,

When I plug the Acer Liquid Z220 smartphone to the USB charger or the computer, the phone gets crazy... First, sometimes, it produces an endless loop error notifying that “system UI has stopped” and I can press indefinitely “OK” or “Report” on the message box.

Otherwise, sometimes, the GUI keeps blinking/restarting indefinitely.

If not, when I’m using the phone through its screen at the same time of charging, the phone gets only some of my taps, generate taps by itself and/or gets slow.

The occurrence of these problems is totally random.

To stop these problems when one of them occurs, I only have to unplug the USB cable. But still, the phone is unusable through its screen while charging. So, when the phone is charging, some of its software and/or hardware are unstable.

When the phone is off while charging, it’s fine: the screen shows the battery charging icon, then it stands by.

Finally, when charging after a few minutes, strangely, it’s not the battery that gets suddenly hot, but the area of the back camera (I suppose some component on the integrated circuit gets hot quickly). Is that normal?

I have not installed any app yet, and the phone has just been out of its package box. No SIM card installed yet.

What is wrong with this phone?

Thanks to enlighten me.

Hardware issue on my opinion, it's better if you check this issue with seller or Acer support service.

probably there is something like a short on the USB or charging circuit.

Hi,

Thanks for the clue. I exchanged the phone with the store according to its return policy, and the new phone works better. But now, I wonder if it's normal that the phone gets warm only after 3-4 minutes of calls or video streaming?
