Special attention will be paid to the features of connecting to phones without Google Play (for example, on Huawei AppGallery) and the nuances of working with the bracelet after resetting.

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ Bluetooth 4.2 enabled.
• 🔋 Xiaomi Mi Band 4 with a battery charge of at least 20% (at a discharge below 10%, the bracelet may not be turned on).
• 📲 Official Mi Fitness app (formerly Mi Fit) or Zepp Life app (for new firmware).
• 📶 Stable Internet connection (for downloading the bracelet firmware and data synchronization).

If you use Huawei or another phone without Google Play, download it. APK-application file from the official Xiaomi site or a trusted source (for example, APKMirror). Do not install applications from unknown repositories - this can lead to data leakage or malfunction of the bracelet.

• 📵 Power saving modes are disabled, which can block the background operation of applications.
