When I am making a call, I can't hear what the caller is saying clearly. Sometimes I can hear the caller but the caller can't hear me. It is the same when the call is on speakerphone or through bluetooth headset.
That's on a Lumia 620.
If I take the SIM out and put it in my Lumia 710, I can hear everything.
I have had the 620 for 5 days. Should I return it to the O2 shop where I bought it?
Is there a fault with the 620?
Thanks for reading.
Sounds like a fault with the phone so you should return it or get it repaired at your local Nokia Care Point.
