I've tried installing it on my s24 ultra. It didn't run. So, I downloaded the official update app which is 4.1.1 and It works on my phone. I've tried most apps and this is the only successful one that works for 32 bit and 64 bit games on my S24 ultra. I've installed the game mode rom that this Vphone Os has. I just paid for a year subscription with my Chinese wechat app. After all this is a chinese app!
