I am experiencing extreme lagging and hanging issue on my Samsung A71..The phone gets hanged and screen goes black ,sometimes for even an hour or more...Can anyone tell what is the problem with my mobile?

Anyone having problem with fingerprint and face recognition?????I think there is a glitch ...Anyone other facing it ?

Jab bhi mm fingerprint sy apny mobile ko unlock krta hu to wo restart hojata h .....Is it hardware issue or software related??? Anyone knows???Model. Samsung A71
