If the problem persists, continue with the troubleshooting steps below.

Start the phone in Safe Mode

Try to check if a recently downloaded app is causing the problem by starting the phone in Safe Mode. When the phone is operated in this mode, only the pre-installed apps are allowed to run, which makes it easier to check whether a downloaded app is a culprit.

  • When Safe Mode appears in the lower-left corner of the screen, release the Volume Down button.

If the problem doesn’t appear in this mode, it could be caused by a downloaded app. Find out which app it is and uninstall it.

A final troubleshooting step to consider is a factory reset. This will restore your phone to its original factory condition. Be aware that this will erase your phone data, so make sure to back up your data.

  • Turn off the cell phone.
  • Press and hold the volume up button and the Bixby button, then press and hold the power button.

  • Press the Volume Down button several times to highlight “Erase Data / Factory Reset”.
  • Press the power button to select.
