Native Android system
Xiaomi's MIUI and Huawei's EMUI are both developed based on the native Android system. In contrast, the native Android system is undoubtedly the Android system with the highest fluency and the least resource occupation. But its interface is relatively simple, and it may be inconvenient to use.
Xiaomi's MIUI system
After nine years of precipitation, Xiaomi's MIUI system has been quite perfect in function, and its fluency has also been significantly improved. However, due to Xiaomi's cost-effective route, MIUI has some built-in advertisements, and the switch settings are quite hidden, and sometimes they can't even be turned off.
Huawei EMUI system
Huawei's EMUI has developed rapidly and its functions have been gradually improved, which is more in line with the usage habits of China consumers. The latest EMUI 9. 1 brings three black technologies to Huawei: Ark compiler, EROFS file system and GPU Turbo3.0. These technologies optimize the Android system from the bottom, improve fluency and save running memory.
