Why Notifications Are Coming to Xiaomi Mi Band 4 – A Complete Handbook for Resolving a Problem

Xiaomi Mi Band 4 remains one of the most popular fitness bracelets due to the balance of price and functionality. But many users face an annoying problem: notifications of calls, SMS or messages from messengers stop coming to the device. The bracelet can vibrate at an alarm clock or reminders of inactivity, but ignores everything else. What is the reason and how to fix it?

In this article, we’ll look at all the possible causes, from the banal (disabled settings in the application) to the technical (firmware failures or Bluetooth conflicts), you’ll get step-by-step instructions for Android and iOS, and also learn when the problem is not in the bracelet, but in the smartphone or even in the servers of Xiaomi. Don’t rush to reset the device to factory settings – in 90% of cases simple actions help!

1. Check basic settings in Mi Fit/Zepp Life

The first thing you need to do is make sure notifications are allowed in the app, and even if everything worked before, updating the app or smartphone could reset the settings.

Open the Mi Fit app (or Zepp Life if you use it) and go to Profile → Mi Smart Band 4 → Notifications.

• 📱 Call notifications (enable vibration and screen highlighting)
• 💬 Messages from applications (select messengers: WhatsApp, Telegram, Viber, etc.)
• 🔔 Other notices (SMS, mail, calendar)
• 🔄 Synchronization of notifications (must be active)

If the options are grey and inactive, the problem may be with Android/iOS resolutions (more on that below) or the app version.Update Mi Fit to the latest version via Google Play or the App Store.

💡

If the list doesn’t have the right messenger (like VK or Slack), try enabling the “Show notifications from all apps” option – but be prepared for spamming vibrations from each push notification.

2. Smartphone settings: permissions and energy saving

Modern operating systems aggressively save battery power, often blocking the background of applications. If Mi Fit can not work in the background, notifications to the bracelet will not come.

For Android (on the example of MIUI, but similarly for other firmware):

1. Go to Settings → Applications → Application Management → Mi Fit.
2. Turn it on: 🔄 Auto-start (allow automatic start-up) 📱 Background activity (to allow work in the background) 🔋 No battery limitations (add optimization exceptions)

3. Problems with Bluetooth connectivity

An unstable Bluetooth connection is one of the most common reasons for the lack of notifications: the bracelet can be connected to the phone, but not actually synchronize the data.

Try the following steps:

• 🔄 Reconnect the bracelet: In Mi Fit, go to Profile → Mi Smart Band 4 → Turn off the device. Turn off Bluetooth on your phone for 10 seconds, then turn it on again. Reconnect the bracelet through the app.

Reset the Bluetooth cache

Settings → Applications → Show all apps → Bluetooth → Storage → Clear cache

Check the distance

Update the bracelet firmware

If notifications still don't come after reconnecting, try connecting the bracelet to another smartphone, and if it's working, there's a problem in your phone (possibly a Bluetooth hardware failure).

4. Update of the bracelet firmware and the application

Outdated firmware Mi Band 4 or Mi Fit apps can cause notification conflicts. Updates often fix sync bugs.

How to update the bracelet firmware:

1. Open Mi Fit and go to Profile → Mi Smart Band 4 → Firmware Update.
2. If an update is available, connect the bracelet to charging (the charge should be more than 50%).
3. Click Update and wait until it is completed (don’t turn off Bluetooth!).

• 🔄 After updating, restart your phone – this helps to avoid conflicts.
• 📱 iOS sometimes requires removing and re-installing Mi Fit, as Apple limits the background work of apps.

If your firmware version is older than 1.0.7.22, an update is mandatory – earlier versions had a critical error handling push notifications from some apps (such as Viber and Facebook Messenger).

5. Conflicts with other applications and services

Sometimes notifications are blocked by third-party programs that optimize your phone or manage notifications.

• 🛡️ Antiviruses and firewalls (e.g. Avast, Kaspersky, 360 Security) can block background activity of Mi Fit.
• 🔋 Battery saving apps (e.g. Greenify, AccuBattery) – often put Mi Fit to sleep.
• 🔔 Notification managers (e.g. Light Flow, Notification History) – can intercept push notifications.
• 📱 Aggressive energy saving firmware (e.g, MIUI, EMUI, ColorOS – Block background work.

How to check:

1. Run your phone in Safe Mode (on Android: press the power button → Safe Mode) If notifications are triggered, one of the installed apps is to blame.
2. Turn off antiviruses, optimizers and notification managers in turn, checking the bracelet.

⚠️ Note: On some firmware (for example, MIUI 12+) There's a hidden feature called Deep Optimization that blocks background work even for applications with exceptions. To turn it off, type ##6484## in the Phone app, then turn it off "MIUI Optimization in the menu that appears.

6. Resetting the bracelet to factory settings

If none of the above has worked, the final step is to completely reset the Mi Band 4.This will remove all data from the bracelet (steps, alarm settings, etc.), but often resolves notification issues.

How to reset:

1. Open the Settings menu → Additional → Reset (or press the touch button for 10-15 seconds until vibration appears).
2. Confirm the reset in the Mi Fit app.
3. After reset, reconnect the bracelet to your phone and set up notifications again.
