Should I sell my Huawei smartphone or what do you think?
Yes, do that… Mate 20 Pro?
Pay maximum prices up to 10 Euro 😁
Why?
There's no reason that you will regret because as a huawei user you will not feel comfortable with other brands only Samsung but these offer a weak battery performance.
As for the Android problem, Huawei continues to provide security updates. The smartphones will not change.
