[Feature request] Sticky warning notification for VoLTE not yet re-enabled after OS upgrade.

[oasisfeng]

After an OS upgrade last night, I forgot to re-enable VoLTE in Pixel IMS, leading to a couple of missed calls today, until my wife told me the situation via IM app. This also happened in the past two months for monthly OS upgrade.

Could you consider adding a quick check on device boot-up and show a sticky warning notification if VoLTE needs to be re-enabled after a recent OS upgrade?

Additional context

My carrier uses 2G network for voice calling if VoLTE is not enabled on the phone. But 2G cells are rare nowadays, and I also disabled 2G in system settings for security reasons.

Hi! This application heavily depends on Shizuku (including reading current IMS registration state), which requires explicit permission grant action from user after initial boot. Therefore it is not possible to create an automated notification after boot up warning about disabled VoLTE (or VoWiFi).

The application reads the configuration from the device, and the display toggles If we save the toggles as a config then compare it with the one we read, it can work

It would be very handy to have it enabled across OS updates as lineageos nightly updates quite frequently, like on weekly basis.
