No incoming calls after update ROG Phone 9 Pro - (v. 35.1810.1810.411).

[Svetoslav88]

Model: Asus ROG Phone 9 Pro

Software version: WW_35.1810.1810.411

Region/Carrier: Bulgaria/A1

Issue description:

After the latest update (version 35.1810.1810.411), my device stopped receiving incoming calls. Outgoing calls and mobile data work normally, but when someone calls me:

The phone does not ring and I do not see any incoming call screen.

Sometimes the call goes directly to voicemail for the caller.

Steps already tried:

Factory reset (problem persists).

Reset network settings.

Tried SIM card in another phone – works normally there.

Tried another SIM card in my ROG Phone 9 Pro – same issue (no incoming calls).

Disabled 5G / tested with LTE only.

Toggled VoLTE on/off.

Expected result:

The device should be able to receive incoming calls normally on the supported network.

Actual result:

Incoming calls are not received on the phone since the update.

Request:

Please investigate this issue. It looks like a firmware bug introduced after the update. I can provide system logs if needed.

Hello @Svetoslav88 
I'm sorry to hear you are experiencing these issues, a log would greatly help with this.
Please follow the instructions for the log here, as it has to be the log for the mobile network:

Steps to enable the built-in log tool (Bug reporter).
1.  Open “Calculator APP”
2.  Enter “.19595+=”
3.  Select the Log type according to the type of issue you want to capture. “Phone, mobile networks, and signal”
4.  After your selection the log tool will exit so you can duplicate the issue or wait for it to happen. Try to use the screen recorder to show your issue when possible. If you can't screen record your issue, then please take a screenshot right after the issue has occurred (as a timestamp) so we know where to look in the log.
5.  Navigate back to the log tool via calculator and Tap "FINISH AND SHARE".
6. It takes several minutes for the log to generate. You can exit and do other stuff in the meantime. A silent notification will tell you once the process is done. Tap the notification and then the share button to upload the file to Google Drive and share the link with a moderator. Just make sure to change the permission first so that everyone with the link has permission to view it.
Note: When you're no longer planning on logging your device, enter “.09595+=” in the calculator and the log tool will stop as well as deleting all stored log files. Make sure to share via calculator. The files found in internal storage -> asus_log are not the correct files (they are only 1.2kb)

Looks like the new update caused a firmware bug blocking incoming calls on your ROG Phone 9 Pro. Just like Easy Grade Calculator gives quick clarity, Asus needs a fix update to restore normal call functions.
