VoLTE is still broken for mediatek

[realKarthikNair]

Ims app does install now but VoLTE still doesn't work while it does work on https://sourceforge.net/projects/andyyan-gsi/files/lineage-21-light/

I've got volte working

@MisterZtr my phone has Android 11 vendor .. and your GSI installs android 12 vendor mtk ims app for some reason.... So the device does get volte provisioned but the actual feature (volte) never works.

Install it yourself

That causes a signature mismatch issue

[MisterZtr]

No, these ims are signed by me for my gsi PixelOS

@MisterZtr I intend to update IMS MTK to version 14 (u) via link you share, but because it always gives error conflict with package installed, I uninstalled the previous IMS first, but it still gives error and it say "not installed". Finally I tried rebooting, and still can't install the IMS, the network become error, SIM card also become not detected. I try to reinstall another IMS apk also it didn't work(error still say that the package is conflict). Finally forced to reformat the data and back normal again. Can you investigate what the problem is? I thought that updating IMS to a version that matches the Android version would be better, but instead this happened.
