Headphones microphone

[zivfer]

I clicked on the “microphone” tag of this forum post and another FP3 related issue came up from beginning of the year. There’s more info in there…

1. people describing the same symptoms, sounds like “far away, distant, tinny, silent, dull”.
2. a microphone module test that formalizes the record/playback test and

Solutions go from changing SIM cards and/or modem functions (disabling 4G standards). A user describing your symptoms to the point said the 4G mode mostly resolved his issues.

Hi there I had the same problem with the FP3 of my wife. I realized, it was only when I call to other cellphones, but not to wired phone. Finally I could resolve the problem by disabling the “Enhanced 4G LTE Mode”. Settings -> Network & Internet -> Mobile Network -> Advanced Hopefully this can resolve the same problem for others too.

I have the same problem. Only it happens also when recording on Whatsapp. I cannot see any connection between that and a “4G mode”. But I’ll try, thanks.

Actually, after deactivating that “4G mode”, I never experiencend that problem again. Only I noticed during conversation that the voice of my interlocutor sometimes falters… I guess maybe that is the issue for which that mode was developed. Mysteries of the software. But yes, in general yes everything turned out fine.

Would be interesting to dig into the software what this mode is about and its effect on audio profiles.

Edit: behind the option is VoLTE (Voice over LTE / “HD Voice”) and RCS (SMS/MMS successor). Maybe there’s some incompatability with the mobile network operator and the mics go into some kind of fallback? I’m telefonica/vodafone Germany based and having it enabled on both SIMs doesn’t have a negative effect.
