Still nothing

I did regret it at some point since now I am kinda stuck with the beta until the stable is released. There was a time I could not take screenshots with the combination butttons, I had to use Google voice to take screenshots

No don't worry, I did know about that issue and the plan is to flash the stable One UI 4 when it is released in December (hopefully)

No, the beta is not open to South Africa. I used YouTube to install the beta for the same model but released in India. I hear there is a second One UI 4 beta for the s20 and now I am waiting to get my hands on it.

I like the option to choose colours based on the wallpaper. I don't have the stable version though because I have an s20.
