I bought the v8 not so long ago, and it has 16GB of internal memory, but after the system and other things it was a little less than 8GB free, of which I have 1.5 GB available. Recently I bought a micro SD 32gb class 10 (UHS-I) to expand the internal storage and not suffer soon for space, but the computer does not give me the option of formatting required and I would like to know if there is a solution for it.
I would be very grateful if you could help me.
By the way, I have android 7.0.
Greetings.
