Google warns millions to change WiFi setting over security issues: check if your phone is affected

2. I think it depends on the carrier. I also could not find the LTE part.

The presence of VoLTE settings is purely dependent on what carrier you’re using and whether or not your phone is unlocked. If the setting is missing, there likely isn’t anything you can do to shut it off. To be sure, you can always search the setting menu for “VoLTE” and see if a setting appears. On the Pixel 6, VoLTE can’t be disabled since it looks like software updates in 2021 automatically enabled VoLTE and removed the toggle.

So long as Wi-FI Calling is turned off and VoLTE is disabled – if possible – your device should be more protected from the Exynos vulnerability. It’s reasonable to believe Google will release quick security patches to fix the issue in the coming days.
