Firstly, check if your device has sufficient battery power. Connect it to a charger and let it charge for at least 15-20 minutes. If there is a charging indicator or the screen displays a battery icon, then the problem might be resolved by simply recharging the device.

If your device still won’t turn on even after charging, try performing a soft reset. This can be done by pressing and holding the Power button and the Volume Down button simultaneously for about 10 seconds, until the device vibrates and restarts. This method can often resolve minor software glitches and bring the device back to life.

Alternatively, if the above steps don’t work, you can try booting your device into safe mode. This will disable any third-party apps and help you determine if a specific app is causing the issue. To enter safe mode, press and hold the Power button until the Power menu appears. Then, press and hold the “Power off” option on the screen until a prompt appears, asking if you want to reboot in safe mode. Tap “OK” to confirm and your device will restart in safe mode. If your device turns on in safe mode, then the problem is likely due to a recently installed app.

If all else fails, and your Galaxy S21 still won’t turn on, it may be time to contact Samsung support or take your device to an authorized service center. They will be able to diagnose the issue and provide you with the necessary solutions or repairs. Remember to provide them with as much detail as possible about the issue and any troubleshooting steps you have already taken.
