Connecting Xiaomi Mi Band 3 to Samsung Phone: A Complete Guide to Error Solutions

Why Mi Band 3 doesn’t want to be friends with Samsung and what to do about it

The 2018 Xiaomi Mi Band 3 fitness bracelet is still popular with users due to its reliability and low price, but Samsung phone owners often face problems when trying to connect the device: the bracelet is not via Bluetooth, the Mi Fit application gives out synchronization errors, and notifications come with a delay or do not come at all, it is all about the conflict of communication protocols between the Xiaomi and Samsung ecosystems, and the features of the latter’s energy-saving modes.

In this article, we’ll break down all the current ways to connect (including workarounds for new Android versions), explain why Samsung phones with One UI 5.0+ may need to disable the “Automatic Bluetooth Switch” feature, and show you how to configure the bracelet so that it works stably with notifications from WhatsApp, Telegram and calls. If you have already tried to connect and received an error like “failed to find the device” or “Synction interrupted” – do not close the page, there is a solution!

Preparing Samsung Phone Before Connecting

Before you start pairing, you need to configure the smartphone itself, because Samsung aggressively optimizes the background of the applications, and Mi Fit requires constant access to Bluetooth and notifications. If you skip this step, the bracelet will turn off 5-10 minutes after synchronization.

Here's what you have to do:

• 📱 Update your phone firmware: Go to Settings → Update and install the latest patches. Android versions below 10 may experience problems with Bluetooth 5.0.
• 🔄 Reset Bluetooth settings: Go to Settings → Connections → Bluetooth → ⋮ (menu) → Reset settings. This will delete all the stored devices and clear the cache.
• 🛡️ Turn off power saving for Mi Fit: Settings → Caring for the device → Battery → Background mode → Mi Fit → Enable "Allow background work" and "No restrictions".
• 🔗 Enable permissions for the application: Settings → Annexes → Mi Fit → Permits → Give access to Contacts, Notifications, Locations and Phone.

⚠️ Warning: If your Samsung has Bluetooth Auto Switch (in the Bluetooth menu), it needs to be turned off. It interferes with the stable connection to the bracelet, constantly breaking the connection.

Installation and configuration of the Mi Fit application

The official Mi Fit app (renamed Zepp Life in some regions) is the only way to fully manage the Mi Band 3. However, Google Play has several versions of the software, and not all of them are compatible with Samsung.

1. Download Mi Fit via the official link (avoid clones like "Mi Band Master" - they don't sync with Xiaomi servers).
2. When you first start, select the China region (yes, it’s not a mistake – so more features) and the Russian language.
3. Sign up with Xiaomi Account (if you don’t have an account, create one in advance at account.xiaomi.com).
4. In the app menu, go to Profile → Settings → Additionally and turn on “Show notifications” and “Autosynchronization”.

If after installation the application gives an error "No connection to the server", try:

• 🌍 Change region in your phone settings to India or Singapore (sometimes helps bypass regional restrictions).
• 🔄 Restart the application and clear its cache (Settings) → Annexes → Mi Fit → Memory. → Clear the cache).
• 📶 Connect to another Wi-Fi network or enable mobile data (the problem may be blocking traffic by the operator).

Step-by-step instructions for connecting Mi Band 3 to Samsung

Now, to the process of pairing, follow the instructions strictly by step, and even one point can fail.

Configure notifications and additional functions

Once you’re connected successfully, you need to set up notifications correctly, otherwise you’ll only get vibrations without text or nothing at all. On Samsung phones, this is done in two steps: in the Mi Fit app itself and in the Android settings.

• 📵 Make sure that the phone settings do not include "Do Not Disturb" or "Sleep Mode".
• 🔄 Reconnect the bracelet: in Mi Fit, click "Disable the device", then add it again.
