You're waiting for an important call, you're looking at the Xiaomi Mi Band 4, but the screen is empty -- no notification, no subscriber name. Is that familiar? The problem with displaying incoming calls on this fitness bracelet is common, but in 90% of cases it can be solved without contacting the service, the reasons are rooted in smartphone settings, bracelet firmware or application conflict.
In this article, we’ll look at all the possible reasons why the Mi Band 4 doesn’t show who’s calling, and give you step-by-step instructions to fix them, from basic checks (is Bluetooth enabled?) to hidden Android settings that few people know about, and how to tell a software glitch from a hardware malfunction, saving you time and nerves.
Now, if the bracelet vibrates when you call, but it doesn't show you the number, the problem is the notification settings, and if it ignores the calls completely, it's probably Bluetooth or the application conflict, and let's start with the simplest one.
1. Check basic settings: Bluetooth, permissions and Mi Fit app
Before digging deeper, make sure three key conditions are met:
- 📱 Bluetooth is enabled on your smartphone and the bracelet is connected to the phone (connection indicator burns in Mi Fit).
- 🔔 Notifications allowed for Mi Fit app in Android settings.
- 📞 Calls are included in the bracelet notification settings (more on this below).
How to check:
- Open Settings → Applications → Mi Fit → Notifications on your phone. Make sure the Allow Notifications slider is active.
- In the Mi Fit app itself, go to Profile → Mi Smart Band 4 → Call notifications. There should be a checkbox opposite “Incoming Calls”.
- Try making a test call from another phone, and if the bracelet vibrates but doesn't show the number, the problem is with the display settings (see Section 3).
💡
If after updating Android or Mi Fit notifications stopped working, try to remove the bracelet from the application and connect it again.
⚠️ Note: Some Android firmware (especially Xiaomi with Android) MIUI) The system automatically blocks background Mi Fit activity to save battery. → Battery → Power regimen → Apps and disable optimization for Mi Fit.
2. Update of bracelet firmware and Mi Fit app
More than 40 percent of notification problems on the Mi Band 4 are solved by updating the bracelet or app firmware.The manufacturer regularly releases bug fixes, including bugs with the display of calls.
How to update:
- Open Mi Fit, go to Profile → Mi Smart Band 4 → Firmware Update.
- If a new version is available, click "Update" and make sure the bracelet is at least 50% charged.
- After the update, reboot the bracelet: press the touch button for 10 seconds until the Mi logo appears.
Also check the version of the Mi Fit app on Google Play or App Store. If there are no updates, try uninstalling and reinstalling the app - sometimes helping to reset the accumulated bugs.
| Firmware version | Release date | Does it fix the problem with calls? |
|---|---|---|
| 1.0.9.14 | March 2020 | No (notification bugs) |
| 1.0.9.26 | June 2020 | Partially (only for Android 9+) |
| 1.0.9.58 | October 2020 | Yes (recommended version) |
| 1.1.0.14 | April 2021 | Yes (full support for Android 11) |
3. Set up the display of call notifications
If the bracelet vibrates when you call, but it doesn't show you the number or name of the caller, the problem is the notification settings. Mi Fit has a separate setting that's responsible for that.
How to set up:
- Open Mi Fit → Profile → Mi Smart Band 4 → Call notifications
- Make sure it's on: 📞 "Showing incoming calls" 👤 "Show the contact name" (if disabled, only the number will be displayed) 🔄 "Vibration on the bell"
"Exceptions"
WhatsApp Calls
If there are any calling apps on the exclusion list (e.g. Skype, Viber, Zoom), remove them from there, and make sure that your Android settings for those apps allow you to access contacts and notifications.

4. Conflict with other applications and "Do Not Disturb"
Call notifications are often blocked because of:
- 🛡️ Third-party applications (e.g. Clean Master, Battery Saver) that optimize background processes).
- 🔕 "Do not disturb mode on a smartphone or bracelet.
- 📵 Other fitness bracelets connected to your phone (e.g. Huawei Band or Honor Band).
How to check:
- Turn off "Do Not Disturb": On your phone: swipe down from the top edge of the screen and check the icon 🌙. On the bracelet: go to Settings → Do not disturb and turn off the mode.
Check out third-party apps
- Go to Settings → Applications → Permissions → Special Accesses → Battery Optimization.
- Find Mi Fit and turn off optimization.
- Disable other wearables (if any).Sometimes Android only sends notifications to one device.
After discharge:
- 🔄 Update the bracelet firmware (see Section 2).
- 📱 Reset the notifications (see Section 3).
- 🔋 Charge the bracelet to 100% – sometimes a low charge blocks background functions.
💡
Resetting the bracelet is a last resort, but it helps in 60% of cases when other methods have failed.
6. Android 10/11/12 problems and MIUI features
Starting with Android 10, Google has tightened its notification policy, which has led to problems with the Mi Band 4, especially Xiaomi’s MIUI 12+ smartphones, where the system aggressively blocks background processes.
How to set up on modern versions of Android:
- Allow autorun for Mi Fit: Go to Settings → Applications → Application Management → Mi Fit → Autorun. Enable permission.
- Disable Battery Optimization: In the same app settings, find Battery Optimization and turn it off for Mi Fit.
Set up notification rights
- Go to Settings → Notifications → Additional → Notification Channels → Mi Fit.
- Make sure that the incoming call channel is given high priority.
For Xiaomi owners with MIUI:
- 🔧 Enable "Show notifications on the lock screen" for Mi Fit.
- 🔄 In "Developer Settings" (how to turn on: Settings) → The phone. → Version. MIUI — tap 7 times) disable "Restriction of background processes".
7. Hardware malfunctions: when it's time to go to service
If you’ve tried all the methods, but Mi Band 4 still doesn’t show calls, there may be hardware issues:
- 🔋 Battery wear – when low charge, the bracelet turns off “unnecessary” functions, including notifications.
- 📡 Damage to Bluetooth module (bracelet connects, but communication is unstable).
- 💧 Moisture intrusion – even if the bracelet is working, contact corrosion can disrupt data transmission.
- 🔧 Mechanical damage after falls or impacts.
How to check:
- Test with another smartphone: Connect the bracelet to another phone (preferably on pure Android) if the problem persists - malfunction in the bracelet.
- Charge check: Charge the bracelet fully and observe the behavior. If the notifications go missing when the charge is below 30%, the battery is to blame.
- Visual inspection: Check the charging connector for oxidation or contaminants.
⚠️ Warning: If the bracelet stops vibrating when ringing and does not respond to touch, this is a sign of failure of the vibrating motor or damage to the plume, in which case repairs will cost more than buying a new Mi Band. 6/7, It is therefore more appropriate to update the device.
