How to Fix a Galaxy S25 Stuck in Boot Loop or Constantly Restarting

If your Galaxy S25 keeps restarting or gets stuck on the Samsung logo, the issue is usually tied to software corruption, a bad app, or damaged cached files. Work through the steps below from least destructive to most aggressive.

Method 1: Force restart the phone

A temporary startup glitch can sometimes clear after a forced reboot.

1. Press and hold Volume Down and the Side key together.
2. Keep holding for around 10 to 20 seconds.
3. Release the buttons when the Samsung logo appears.

Method 2: Charge the phone first

Low battery can trigger unstable startup behavior.

1. Connect the phone to a working charger.
2. Leave it charging for at least 30 minutes.
3. Try starting it again.

Method 3: Boot into Safe Mode

This helps determine whether a third-party app is causing the restart loop.

1. Power on the phone.
2. When the Samsung logo appears, hold Volume Down.
3. Keep holding it until Safe mode appears.
4. Uninstall apps you installed shortly before the problem started.

Method 4: Wipe cache partition

This step clears temporary system files without deleting personal data.

1. Turn the phone off.
2. Boot into Recovery Mode.
3. Select Wipe cache partition.
4. Confirm the action.
5. Choose Reboot system now.

Method 5: Free up storage if the phone can boot briefly

Low internal storage can cause Android to crash or restart.

1. Open Settings.
2. Tap Battery and device care.
3. Tap Storage.
4. Delete large files or unused apps.
5. Restart the phone after freeing space.

Method 6: Reset all settings

Misconfigured settings can cause repeated instability.

1. Open Settings.
2. Tap General management.
3. Tap Reset.
4. Choose Reset all settings.
5. Confirm the reset.

Method 7: Factory reset the phone

This is often the most effective fix for severe software issues.

1. Back up your data if possible.
2. Boot into Recovery Mode.
3. Select Wipe data/factory reset.
4. Confirm the reset.
5. Reboot the phone after the process finishes.

Method 8: Seek professional repair

Persistent boot loops after a reset may point to hardware failure.

1. Stop repeated restart attempts if the phone overheats.
2. Contact Samsung support.
3. Visit an authorized repair center for diagnosis.
