After launching the Android Q beta testing program, Xiaomi’s MIUI team is now ready to release the full MIUI 10 Beta for Mi 9 users in China.
Those who sign up for the beta test should read the OTA software update. Otherwise, follow the manual route and flash the firmware yourself. MIUI boss Zhang Guoquan has released some examples of MIUI 10 Beta on his personal device. He looks very similar to MIUI 9.
In general, Android Q focuses on privacy by allowing users to set application-specific permissions, even for apps running in the background. As always, you should be cautious with beta versions of the software, as not all bugs are fixed and you may have problems.
