So, my smartphone is a Xiaomi POCCO C3 NFC.
I tried to adjust an screenshot, but on Dekko 2, the mail with the screenshot to my laptop stuck in drafts, so I could not send it.
But imagen, that the line with the text massage is flat and not "zickzack" respectively "hilly".
A popup come for a second, to allow to use the microphone. But the second its to short to allow it.
In android i could open "apps" - "whatsapp" an "allow using the microphone". But on UT I could not find this adjustment.
On my old phone I used the dictaphone app a lot. But on UT it nether work.
Ok, I just reboot the phone, and now everything works.
Since I use UT (around two weeks), it change. Somtimes the microphone works, somtimes not.
But I can make calls all the time normaly.
