  • At the Android logo, release the keys
  • In case the Maintenance Boot Menu appears, select Normal Boot – if not, allow the device to restart as usual

  • Turn off your Galaxy S10 smartphone
  • Hold the Power button key and release it when the SAMSUNG logo appears on the display
  • Right away, press and hold the Volume Down button
  • Hold that key until the smartphone restarts, and the Safe Mode text appears in the bottom left corner
