Android 12 Broke ROG Phone 3

[Aerevyr]

Please tell us some basic information before asking for help:
Model Name: ASUS ROG Phone 3 (Strix version I believe)
Firmware Version: Version WW-31.0210.0210.230
Rooted or not: Not Rooted
Frequency of Occurrence: Persistent (no variation)
APP Name & APP Version (If your issue relates to the app): Phone App
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
After Updating to latest Firmware Version the Phone app immediately "Call Ended" upon dialing a number, with the exception of emergency services (911) takes about 30 seconds but begins to ring.
Incoming Calls go straight to voicemail.
VoLTE option is not found in settings except in the "STATUS BAR ICON MANAGER" section where I can choose to have it display in the status bar (it doesn't display)
I have :
- Restarted the Phone
- Shutdown and Turned back on the Phone
- Enabled, waited up to 30 minutes, and Disabled Airplane mode multiple times (dozen+)
- Factory Reset the phone
- Installed Alternate launchers
- Gone through support with my Carrier (no issues on their end the SIM and everything works perfectly fine in non-ASUS-Android 12 phones)

Same issue with T-Mobile USA, only "connects" to 3G or EDGE. Tried rolling back to Android 11 without success

Strange. I'm also on T-Mobile US, and I'm not having any issues connecting to 4G or 5G.


Not to say you're lying or anything, but I wonder what's different between us. I had also participated in the A12 beta program, btw.
I guess I would suggest making sure your APN settings are correct.

BYOD T-Mobile data & APN settings
Also, sometimes the "Fix Connectivity" button in the Internet settings helps:

And, one last option would be the Reset Network option (System :right_arrow: Reset options). Keep in mind that completely resets all network, WiFi, and Bluetooth settings.

Weird as hell, so for some reason you can use voLTE while the other guy can't despite using the same Phone.
Are you rooted?
Did you setup anything manually such as APN etc.?

Nope, no root. I did manually configure APN to match what's listed in T-Mobile's help article, because (if I remember correctly) the default configuration didn't match up.
Oh, there was one other thing I did: I used adb setprop to forcibly enable VoLTE support... and it seems to have worked, and stuck enabled even after reboots and updates.
However, I don't think I did anything specifically about LTE and 5G support.
