A year ago I bought the BV9600 PRO P60 and it was promised that in the spring of 2019 it will get Android 9. Unfortunately, BV has other plans and we will not see a new system, especially Android 10.
Forget it. BV has a bad name for its client. So you bought the problem is yours and they will encourage new customers to buy. It's the same with this forum, you can register but you won't post anything because you can't post. BV rules BV advises BV will never betray you - sarcasm
