• 📱 Mi Band 4 doesn’t sync with smartphone via Mi Fit or Zepp Life despite app reinstalling.
• 🔋 The battery is discharged too quickly (for example, in 12-24 hours instead of the standard 14-20 days).
• 📊 Data on steps, pulse or sleep are displayed incorrectly (jump values, zeroing statistics).
• 🔒 The bracelet requests PIN-code that you did not install or is blocked after several failed attempts to enter.
• 📲 You sell or transfer the bracelet to another person and want to delete personal data.
