Hi there, unfortunately there's nothing more to do except contacting your seller to have your phone replaced under warranty (and hoping you bought it from a trusted seller..).

good morning 
before i wont to contact my seller , 
at first we must be sure that is an hardware issue ,
i wont to tell you that yesterday i decrypted the phone , fingerprints is working for a will and again is stoped .
today i have another problem with playstore that is in boucle waiting for downloading without starting download .
is't an problem in the android system injected in the phone ?, maybe some bug is happen when the operator inject the firmware in the phone By the functional test machine in the factory ? 
if yes how we can re-inject an android with the blackview user ?

Hi there, such issue is an HARDWARE fault. Please contact your seller to have your device replaced/repaired under warranty.
