You can use the Safe Mode feature on your Samsung Galaxy S9 to access the operating system with default software. Use Safe Mode if you have installed something on your S9 that no longer allows the device to start successfully. Just use these steps.
Turn On Safe Mode
- Power the phone off.
- Once the phone is off and all lights are emitting, press and hold the “Power” button to turn the S9 back on.
- When the Galaxy logo appears on the screen, press and hold the “Volume Down” button.
- Continue to hold the “Volume Down” button until the phone completely boots. You will see the words “Safe Mode” appear in the lower left corner of the screen if you performed the steps properly.
While in Safe Mode, you may not be able to use certain features or applications. The device is in a “bare bones” state where just the essential software is loaded. This allows you to get into the device quickly, enable or disable whatever you need to, then restart.
Turn Off Safe Mode
To turn off Safe Mode, powering the phone down, then back on should do the trick. Be sure to power completely down.
If you still continuously start in Safe Mode and cannot get out of it, a malfunctioning app may be causing the problem. You may have to uninstall apps until you track down the one that is causing the problem.
Another problem could be that your Volume Down button is stuck. Press it a few times to loosen it up, and make sure your phone case is not applying pressure to the button when you start the device.
