Xiaomi Mi 9T, Redmi K20, & Mi Note 10 system lag to be fixed this month; users will soon be able to suggest improvements to MIUI

Xiaomi just announced on the Mi Community that they’ll be pushing bug report statuses for some of the most commonly reported issues on various Xiaomi devices on a biweekly basis through MIUI UX Optimization Announcements.

While the initiative isn’t exactly novel since MIUI Weekly Bug Reports were indeed being published for the past couple of months, there is now a greater hint of officiality.

Our past coverages on the weekly bug reports discuss issues like random reboots on the Xiaomi Redmi Note 9 Pro and touch screen problems on the Mi 11X. These can be found here and here.

And now, the first volume of the MIUI User Experience Optimization Announcement acknowledges several trending issues and even gives ETAs for when they’ll get fixed.


But before we dive into that, you will be pleased to know that Xiaomi will be launching a ‘user proposal feature’ for the Mi Community in October 2021.

Through this, users will be able to put forward their own suggestions and needs for Xiaomi products. These suggestions will then be processed by Xiaomi’s employees themselves.

Anyway, the progress of the bugs and issues that Xiaomi is currently working to fix has been given below:
