I have had my Nokia 5.1 since Christmas. I started noticing problems since Jan/Feb, which was my voice randomly cutting out on calls, but still able to hear the person on the other end. Now it's constantly cutting my voice out. I am also not receiving calls anymore. My phone won't even ring, no notification of a missed call. But my service provider will notify me that I somebody tried to call me.
Also I am not receiving any notifications for any apps that I have, even though they're turned on in the app and also phone settings.
I'm thinking I might need a replacement?
