Not exactly good but the way I do it is to use a USB HDD to have backups and E2EE cloud solutions

They are very security fovused and is against f-droid’s poor security practices. They do push accrescent through their stores tho

I assume you’re using it with bootloader unlocked. The issue is somehow some malware injects your phone and roots it, it can just install itself as a system service and just live there and you’ll never know. The security feature that protects against it is disabled once bootloader is unlocked.

Also I’ve heard that LineageOS has not all security updates present since some firmware updates needs to be provided by the specific manufacturer. For Pixel, Google provides it and GOS uses it.

Yeah it’s ironic but what is the alternative? At least we CAN remove Google’s known spyware from the device, and there’s no evidence of firmware level spying. If you get Samsung, or some chinese crap, you can’t remove Google period, and you might get spied by the manufacturer as a cherry on top. There is no way to have a perfect solution, well unless Samsung starts to provide Custom ROM support or something.

Cellebrite and the new Grayjack or something both has zero ways to crack a GOS phone 🔥

Did you fix VoLTE stuff? What was the issue?
