Hi,
I was playing around with the phone for a bit and left it charging over night. I was already wondering why there is no indication of charging. Today I eventually noticed that the battery level hasn't changed.
So I hooked the USB cable onto my lab power supply, to check whether there is current or not. Indeed there was - right at the limit ... which was set to 2 amps. So I guess a short or something...
I narrowed the issue down to the daughter board (ZQ01_SUB_V10). I disconnected everything except the flex board to the speaker. Still, the current limiter of my PSU
immediately kicked in as soon as the USB cable was connected.
Any idea how to fix this or getting a replacement?
Cheers, ya
