Android version of dolphin problems

[Wyliemaster]

I downloaded the Android version of dolphin and I have the requirements to play games: 4gb ram, open go 3.2, 64 bit. My phone has an octocore processor and is android 8 so it is able to run games. However, when I try to load games (sa2b) I get booted out after the controller loads without any error message telling me what's wrong. I hope someone could give me some advice for this issue. I have no idea what to do now...
