Can not use quickcharge 2 charger on XA2

I have seen this behavior with some charge/data cables, it seems as if not all cables are quickcharge compatible, try with another cable.

hi, thanks for your answer, the cable I'm using is the original that came with the box, and also de charger. Had no problems before, anyway... I will flash again and report if the issue still persist.

Using a charge that for sure works in Quickcharge mode (the USB-charger that Logitech provides for UE Megaboom speakers. Supports 9v and 12v output), and that has correctly worked on Xperia X (goes into 9v mode, charges battery at 1800mA), plugged with the official Sony cable, and I am also getting spotty function.

• Sometime it does the start/stop constant restarting (and in Chargemon voltage stay around 5v level, and the current dips every now and then) but none the less eventually charges the battery.
• Other times, when I get back to the phone, I notice that Chargemon reports the voltage at around 9v level.

It seems that the XA2 has currently troubles correctly negociating QC.
