New OnePlus5 Issues

[Donnieclark]

hi,

It's not even been a month since I purchased OnePlus5.

The phone is frequently restarting on its own and sometimes I experience lag while gaming or browsing.

Unable to hear the person on the other end and they are unable to hear me while on a call.

Whats the exact issues here?

What sholud I do? Should I replace it?

Please help.
Thanks!

I didn't find the right solution from the Internet.
