Loudspeaker stopped working

Any suggestions for how to make the …ear/internal/bottom speaker work again?
When receiving or making a call without using bluetooth or the loud-loudspeaker (Which I gather is referred to as top speaker?) Otherwise I can’t hear anything, but the microphone works.

I tried the trick with Accessibility Settings > Mono > balance all the way to the left and it didn’t fix the issue. Do I need to do a reboot?

My suspicion is that its a SW problem, not a HW. Kind of like if the speaker jammed in switched off position because of using bluetooth headset, all though I turned off bluetooth.

Welcome to the Community Forum.

To find out if something is a hardware or software issue, the Fairphone 4 has an extensive set of hardware tests. Dial this (in your telephone app) to access all tests:

* # * # 2 8 8 6 # * # *



It first resulted in the below, but after I switched off Bluetooth it reported all as working
…In other words I believe the speaker worked during test, however still not in real life…
