3. Boot Samsung S7 in Safe Mode

Safe mode launches the phone without third-party apps.

To enter, press Power after the Samsung logo appears, then immediately press and hold Volume Down until ‘Safe mode’ appears. If your phone turns on in safe mode, a downloaded app is likely causing issues.

4. Boot in Recovery Mode

Recovery mode starts the device without the main OS.

Press Home + Volume Up, then Power and use volume keys to select ‘Wipe cache partition’ to fix software crashes. Once recovery is complete, select ‘Reboot system now’.

5. Reset App Preferences

Go to Settings > Apps > Menu > Reset App Preferences.

This resets all custom app restrictions and defaults that may be causing problems. Resetting preferences can help fix issue.

6. Wipe Cache Partition

Boot into recovery mode like above and select ‘Wipe cache partition’ to delete corrupted system cache files. After wiping cache, select ‘Reboot system now’ to restart your phone.

7. Try a Different Charger and Cable

Test different chargers like computer USB, wall outlet, wireless charging etc. Use a different USB cable too. This helps isolate whether the issue is with a faulty charger/cable.


8. Get it Professionally Serviced

If all troubleshooting fails, get your S7 checked out by Samsung technicians. Hardware faults like motherboard or charging port issues need professional servicing and repairs.
