    Hi!

     

    I bought recently from Banggood an ALLDOCUBE M8 tablet. It’s very nice, and fast, but I have some problem.

    I can’t set the screen brightness. The brigthness slider is work, but do nothing. 😥

    Another problem: the B20 frequency don’t work. I try this on Hungary in a village in T-Mobile network, but the 4G is not work, only 3G. Another mobile device (Redmi 6) is work on B20 in this place.

    Please help me!

    THX
