Can you add more Mi Band 4 icons?

No. The icons are integrated directly into the firmware of the bracelet and no third party application can add them.

Only Xiaomi can add them into the firmware and if they do, we'll always update our application to give you all the great features like multi-line text display. Please do not down-rate us or ask us to add icons. It's truly not technically possible.

 

Icons available since firmware V1.0.5.10:
