I don't know any problem from the new unit installed operating system. But I do believe that when the Blackview Company introduced new update it would be good for me to update it the first time. But I still never encounter charging type-c my phone with the phone ON. Later with the 2nd update, I am experiencing the phone is not efficiently charging while it is plug with phone ON. So I decided to try wireless charging with 3rd party wireless charger even attaching wireless charging adaptive patch but still doesn't work. I found wireless apk at Google play to confirm whether my BV6800 is wireless charging compatible. The answer was negative, why is that? Then how can I go back to my first update to get good charging even just type-c ?
