This is a possible solution if you find that your phone won't connect with your saphe device. This will reset your Bluetooth and remove all bluetooth units from your phone. This means that all previously paired devices must be paired again after you have cleared the bluetooth data. 

This is how you do it:

  • Go into settings
  • Tap on Apps
  • Tap on "See all # apps"
  • Tap on the menu (three vertical dots in the upper right corner)
  • Tap on "View system"
  • Find and tap on "Bluetooth"
  • Tap on "Storage"
  • Tap on "Clear data"
  • Tap on "OK"
  • Restart your phone
