If i have no solution to this problem before Sunday ,i send the phone to the seller and i get refounds
So you're giving blackview one whole day before you send it back, i dont know if you've ever been asked to troubleshoot anything, but to do so you need all the information you can get, you have provided 2 pieces of information, one being your problem, the other being your build number
that is not enough information to diagnose your problem.
