I have an S22. I haven’t figured out even how to unlock it, much less install another OS onto it. It comes in a few different versions, and the one usually sold in the US by carriers is very well locked down and is near impossible to unlock.
I’ve read some people have been able to flash the ROM, but I don’t want to take the chance.
Anyone who knows how to load e/OS onto the S22, I’d be curious to know. It’s otherwise a nice phone with a lot of horsepower and a nice camera.
