Nah my physical mic itself is fine. Recorder app works no problem.I had a similar issue while my XZ2c was running the stock OS, had to open the phone up to replace the microphone which then fixed it. It's worth replacing the battery during the process if the phone is opened up. If possible, I would try to temporarily reinstall the stock OS to try rule out any possible hardware failures before attempting to open the phone up though. It is very easy to ruin the display panel by poking the thin plastic sheet too far under the display. I've ruined 3 out of 5 display panels this way on various phones and had to buy replacements.
I'm already needing to replace the display, so probs will look into the battery just in case thanks for tip.
But my issue turns out is with T-Mobile.
The stupid sim only works for like 15 seconds and it only works after I put it in my Xz1c, boot, then take it out and put it in Xz2c haha.
I thought the VoLTE problem is fixed in Lineage 18???
Anyone else using this rom with T-Mo in the US?
