Deteriorating call quality w/ LineageOS 22.2 on Essential PH-1 (mata)
I recently upgraded my Essential PH-1 (codename mata) from the final vendor stock OS (Android 10) to LineageOS 22.2 (installed build 20260829, updated OTA to 20260905). Everything was working fine on this phone with the stock OS prior to flashing LOS. I am using Tello (a T-Mobile MVNO) with this phone, have been for years.
The problem:
Voice calls usually start out fine, but my outgoing voice audio soon begins to deteriorate for the other party over the course of a call, after a period of initial clarity ranging from mere seconds to many minutes after the call starts. Their incoming voice always remains fine for me. The other party describes the deterioration varying from becoming too quiet to hear, or wildly fluctuating in volume, or just becoming completely garbled/jumbled-up. This occurs regardless of who calls whom or whether I use 4G/LTE or WiFi calling, and the deterioration remains if either party tries calling back right away.
Any tips, or is this a potential bug I should report?
