I to have this issue its irritating.
When I call out all fine
But incoming sometimes work sometimes not.
I swiped the phone twice
I previously deleted all apps
I stopped Google assistance
I took the sim.out and left it off all night
Nothing changed .
I have the same problem , thought it was an app I had installed called Call recorder (Cube ACR) after their last update noticed I was having the same problem as everyone here so removed the app and cleaned the cache but still happening intermittently so its obvious its the same issue as everyone else here, come on Samsung get it sorted or I wont be buying your products in future.
I discussed with Samsung România and they told me that the Samsung doesn't know about this problem and if this problem really exist, afect only a small number of phones and it's not interesting for Samsung.
They say, if are a cople phones with problems from millions is a hardware problem with the phones and we need to go in a Samsung service to see what is the problem :)).
