I installed the new Samsung update. Ever since then when I call someone I have to talk talk them on speaker phone. I know the ear speaker works because when i call someone on messenger I can hear it ringing through my ear speaker and then it goes silent. I have to use it in speaker as well. It's something to do with the update.
Dude they suck. I just got off the phone with them. They said I need to take it to a service center. I call that service center that's an hour away. He tells me that it's basically **bleep**. I'd have to pretty much just wait til the next update and hope it fixes my problem. Samsung officially **bleep**.
My Galaxy A20S and my Wife's A20S are doing the same thing after I updated them both.
So I know for a fact it isn't the phones, it is an update issue.
I can only use them on Speakerphone or headphones.
