iPhone 12 Mini Earpiece Volume Too Low / Quiet Text Alerts: Solved!
I could barely hear incoming callers speaking to me through my earpiece on my iPhone 12 Mini.
Also my text alerts were very quiet.
I tried all of the fix suggestions found in this community and on YouTube (most of which were all the same unsuccessful ideas.)
Finally I found this video, and it solved the problem. (You'll need to link to his sound video on YouTube on your phone after watching his instruction video. Link to that is below.)
Now my volume is almost too much!
