WebRTC crashes Galaxy Tab A7 Lite on Verizon

[CLShortFuse]

If a Galaxy Tab A7 Lite is connected on Verizon and tries a WebRTC call, the entire network stack will crash. This happens on Chrome and on Firefox and is a device-wide issue. If using WiFi, there is no issue. If using T-Mobile, there is also no issue.

Here's the Google Chromium bug filling, but since it happens on Firefox as well, it's a Samsung issue:

This would be a Verizon issue. The fact that it does not happen with another carrier should be your clue that it's a Verizon issue. You need to contact their support. Samsung owns neither chromium nor Firefox, so I don't know how you conclude it's a Samsung issue.

If you read the Chromium issue it details that it happens

* Regardless of carrier: (Verizon and Vodaphone which both use VoLTE) 

* Regardless of manufacturer: (Google and Samsung)

* Regardless of application: (Chrome and FireFox)

It happens on devices that use the same Samsung EXYNOS modem. That means it's a Samsung issue.

It also happens on Galaxy Tab S9 FE, Samsung A33, and Galaxy Tab A 8.4.

You confirmed yourself, that it does not happen with T-Mobile only Verizon and Vodaphone, both of which disable VoLTE as a user control. Therefore, it is not a Samsung issue, it is a carrier issue. It is the way Verizon configures their software for Samsung/Android phones.

That's not how engineering bugs work. You can't just disable a feature on a device when it has bugs and consider it "fixed".

[realaud]

They don't disable the feature because ir has bugs. Verizon deliberately takes that settinf out of the end user's control. It is not a Ssmsung issue. Ut is a Verizon issue.

[CLShortFuse]

The issue is not the removal of a feature. The issue is a crash because of the Samsung modem. If you don't understand the issue, please do not reply to this post.
