Cant hear caller ZFlip

[CarlyD28]

Hi, I have the Samsung ZFlip3 and I have started to not be able to hear callers. I've tried disconnecting WiFi calling, done a factory reset and checked all of the settings, and it did work briefly last night, but now the issue is back. I haven't done anything since the reset. Has anyone had the same issue and what did you do to fix it?

Hi @CarlyD28 

May I ask >

• Is this issue happening elsewhere or in a particular place ?
• Is this happening with all your calls or with a particular contact ?

Troubleshooting ideas >

• Settings > General Management  > Reset > Reset Network Settings. 
• Try your sim card in another phone to help rule out your current phone or your sim card as the possible issue.
• Try another sim card in your phone.
• There is a diagnostic tool in your Samsung Members App.
• A Samsung Experience Store or Samsung Service Centre can check out the phone.

I wish you all the best.
