Software
[edit]User interface
[edit]The series is powered by Android. Among other features, the software allows users to maintain customized home screens, which can contain shortcuts to applications and widgets for displaying information.[15][16] Shortcuts to frequently used applications can be stored on a dock at the bottom of the screen.[17] A tray accessed by dragging from the top of the screen allows users to view notifications received from other apps. It contains toggle switches for commonly used functions.[18]
The series uses MIUI 12.5.1 based on Android 11. MIUI 12.5 has a minimalistic design and some elements of the original Android, such as the toggle switches in the notification tray, and the app drawer in some markets. The app drawer can be customized, such as sorting different apps into categories, and the colour of the background. MIUI 12.5 also supports dark mode, making the system background turn black, and icons darken as well, reading mode, and night mode. The notification tray can be customized, such as the looks of the notification cards. MIUI 12.5 also has per-app background activity control. The task switcher shows all of the opened apps in two columns. MIUI 12.5 has split-screen capability accessible through pressing and holding an application in the task switcher.
Features and apps
[edit]MIUI 12.5 is a slight improvement over MIUI 12 and comes as an intermediary between MIUI 12 and the forthcoming MIUI 13.[19] It has notification and alarm sounds that change their sounds depending on the time. MIUI 12.5 continues to have Mi's own gallery, music, video player, and document viewer. There is a paid option for streaming in the music and video player in some markets. MIUI 12.5 also has a Security app, which scans for malware, clears RAM space, manages permissions, quota usage, and battery-draining apps. In some countries, the first-party applications will show ads. This is one way Xiaomi manages to lower the cost of their phones.
Android fork
[edit]The Redmi Note 9 series have gone through 3 major Android updates, those being Android 10, Android 11 and the last major release being Android 12.
For Xiaomi's interface, or in general terms used to describe other brands interfaces as Android fork, those being MIUI 11, MIUI 12, MIUI 13 and the last fork release being MIUI 14.

GSMArena rated the series (except Redmi Note 9) 3.8/5 stars. They praised the screen, the battery, the performance for the price, good image quality for the cost, the design, and the availability of NFC (Note 9 Pro (global) / Pro Max only).
