Users reported that when an Android game is launched, the system detects it as an application launched from an Android computer emulator, and not from a mobile device. This affects the game itself, since the game server in this mode applies the appropriate settings. It is reported that the performance in this case may be lower than when running on an Android smartphone.
It is possible that with the release of the stable version of HarmonyOS, this problem will be solved. By the way, it is scheduled for June.
Testers have previously said that HarmonyOS requires less RAM than Android with EMUI firmware.
