I updated my Samsung galaxy s20 5g and now i have to put my phone on loudspeaker to hear my contacts calling me and they can hear me but I can't hear them and call will cut out , also sometimes phone won't ring at all will go straightto voicemail. . Non contacts can phone I will hear it ring. Sent it in for repairs, got it back same problem. Anyone else has the same problem? Is it the software? Can I have the previous version installed again? Any help please. Thanks
