FR: Add Voicemail apps to Android Split Tunneling settings by default

timtailscale commented 2 months ago

What are you trying to do?

Users have reported that being connected to Tailscale can cause Voicemail apps to stop working. As a workaround, the Voicemail app can be added to the Split Tunneling settings in the Android app, which prevents them from being routed over Tailscale. Because this is a core functionality, we should consider whether we can add voicemail apps to the split VPN configuration by default.

How should we solve this?

Add Voicemail apps to the list of apps automatically added to the Android split VPN configuration.

What is the impact of not solving this?

Voicemail is silently broken on some carriers and phones by default.

Anything else?

@timtailscale Can we get a list of application identifiers for these voicemail apps?

@agottardo com.samsung.attvvm appears to be this user's particular case. We could potentially match with regex like com\.samsung\..*vvm, to cover all possible carrier variants. Below is a list of other voicemail apps I was able to find:

com.att.mobile.android.vvm
com.tmobile.vvm.application
com.metropcs.service.vvm
com.mizmowireless.vvm
com.vna.service.vvm
com.dish.vvm
com.comcast.modesto.vvm.client

Reopening as we might need more entries in the future as users report them.
