I have google play store installed and also terrarium, and IPVanish. Other than that, I have taken off everything else. when I use the speedtest app, i get the same black screen and it takes forever to start running although when it does, i get a fast connection with the vpn on or off.
i have tried looking around these forums and a few other places but cannot find anything that really seems to answer the question. i wish I could root this tablet but that does not appear to be an option.
any advice/help would be appreciated, at this point I am thinking of doing a factory reset or just buying a better tablet. thanks for the help.
