Hi, I also have the same problem. After the first top-up made by me, the percentage reached 79% and after another top-up it reached only 50% without the fast charge starting. I am trying to use the USB cable and charger of my old BV 8000 Pro
hi, I encountered a problem on my BV 8000 pro. I can not update the firmware of the smartphone, is still in version 7.1. I do not know what to do, maybe I have to format the phone?
