FP4 Microphone not working on loud speaker on GSM calls

[yvmuell]

I was not talking about cleaning anything. I was talking about testing the mics.

Edit:

To nit pick: you had an issue that was fixed and was not about bad GSM=2G calls

[SOLVED] Fairphone 4 bad signal. Especially Upload speeds & regular calls

After the December update I can confirme that Fairphone 4 is now behaving like at 2022 phone in france on the free mobile network. I even noticed once having a better connexion than a Iphone from 2012 which never happened to me before! This December update and then one before have been a very big leap in usability. Even regular GSM calls have improved, I still have sometimes to deactivate the data in order for people to hear me on the other side of the call. But is is maybe 30% of the time n…

and now you have an issue with Android 13 which is still not about bad GSM calling.

@y_cho

I have a mageor bugs that was solved 6 monthes ago on android 12 that came back :
the inability to phone under bad weather because the phone doesn t switch to 3G to get better signal.

and this issue here is a third one reported under Android 12

And for def of GSM, this was discussed here.

Share you experience with GSM phone quality on FP 5

According to this post, you actually dont use 3G or 2G for calls and thats your issue actually, bad quality with VoLTE And btw in the past your description was the opposite to my understanding, so no VoLTE calling and only 3G.

Overall lot of reports and a bit difficult to follow what the current problem is.
