To remove Safe Mode on a Samsung phone, the common and effective method is to simply restart your device. You can do this by pressing and holding the power button and then tapping "Restart" or "Reboot." If the phone continues to boot in Safe Mode, try pressing and holding the Volume Down button along with the Side (Power) button for about 7 seconds until it restarts normally. If Safe Mode persists after multiple restarts, there might be a physical issue with the Volume Down button, and servicing might be needed. Additionally, Safe Mode can sometimes be triggered by pressing and holding the Power Off option, so avoiding that can help prevent entering Safe Mode inadvertently. If Safe Mode is active, it will show on the screen, and after exiting Safe Mode, you might have to turn off Flight Mode if it was automatically enabled.
