How to change the screensaver on Xiaomi Mi Band 4: all ways + mistake-making

Why to change the screensaver on Mi Band 4 and what you need to know before you start

The Xiaomi Mi Band 4 fitness bracelet has become a hit with health gadgets due to its combination of functionality and affordable price. However, standard screensavers (or "wallpaper" screens) quickly get bored โ€” especially if you see them 50 times a day. Fortunately, the manufacturer has provided several ways to personalize, including installing your own images. But there are nuances: not all formats are supported, and the wrong actions can lead to malfunctions of the device.

Before you start changing the screensaver, consider the key points:

  • ๐Ÿ”‹ The battery charge should be at least 30% โ€“ at a low level, the system can block changes.
  • ๐Ÿ“ฑ The Mi Fit version of the app should be up-to-date (update it to Google Play or App Store).
  • ๐Ÿ–ผ๏ธ Image resolution - only 120ร—240 pixels (for color screensavers) or 120ร—120 (monochromatic).
  • ๐Ÿ”„ Synchronization with the bracelet must be stable - otherwise the new wallpaper will not be used.

In this article, we will discuss all working methods, from standard wallpaper in Mi Fit to install custom images through third-party utilities, and also tell you how to avoid typical errors that can cause the screensaver to remain unchanged or appear clumsy.
