God knows what different they have done with this device. Even the Custom ROMs for this device are full of bugs and unstable. No one has been able to fix them yet in XDA Community. Meanwhile every other Xiaomi device (with Snapdragon SOC) works flawlessly with Customs ROMs and have great developer support. Even the super old ones too.
The Mi A2 had no such problems. It also received the stable Android 10 update, and has super stable Custom ROMs as well. Even Mi A1 has stable Android 10 Custom ROM builds.
