iPhone 12 works Only on Speakerphone

I have I phone 14

I can only use my phone on speaker phone

normal phone hearing speaker not working

How do I increase the volume on my I phone 12 without being on speaker?

I went to the local T Mobil store to see if they could solve the issue. Just so happens their promotion was a new I phone 16E buying my 12, I only pay $5.00 more a month now. It’s their problem now! Thanks be to God!
