Connecting to room on Android 12 over cellular causes entire device network interface to disconnect

[futurealecks]

• [x] I have verified that the issue occurs with the latest twilio-video.js release and is not marked as a known issue in the CHANGELOG.md.
• [x] I reviewed the Common Issues and open GitHub issues and verified that this report represents a potentially new issue.
• [x] I verified that the Quickstart application works in my environment.
• [x] I am not sharing any Personally Identifiable Information (PII) or sensitive account information (API keys, credentials, etc.) when reporting this issue.

Expected behavior:

User should be able to connect without cellular network drop.

Actual behavior:

When a Twilio video participant joins a room from an Android 12 device over cellular (tested multiple Verizon SIMs throughout the US) the cellular radio completely drops, resets, then drops again. This occurs in a continuous loop.

• [x] Behavior doesn't occur on Android 11.
• [x] Behavior doesn't occur on Google Fi.
• [x] Behavior doesn't occur Android 12 device is connected to a VPN.
• [x] Tested on Pixel 3, 4A, 5, and 6 running Android 12
• [x] Doesn't occur with other known WebRTC clients such as Google Meet and Signal

As soon as the the Verizon user joins the call it's cellular interface drops.

Hi @futurealecks , are you using android webview?

[futurealecks]

Hello @charliesantos , no we are not using webview.

[charliesantos]

@futurealecks thanks for confirming. What did you mean by twilio-video.js: 7.0.2 within native Android app? Are you using the Android SDK or JavaScript SDK?

[futurealecks]

@charliesantos: We're using the Android SDK com.twilio:video-android:7.0.2.
