How to Fix a Samsung Galaxy That Keeps Restarting

If your Samsung Galaxy is caught in a continuous restart loop, it can disrupt your daily routine and cause significant frustration. This guide offers a variety of troubleshooting methods to help you identify and resolve the issue so that your phone operates normally again.

Access Settings: Open the Settings app on your device.
Navigate to Software Update: Scroll down and select “Software Update” or “System Updates.”
Check for Updates: Tap “Download and Install” to see if any updates are available.
Install Updates: Follow the on-screen instructions to complete the update process and then restart your device.

2. Boot into Safe Mode

Booting your Samsung Galaxy in Safe Mode disables third-party apps that might be causing the restart issue.

Power Off: Press and hold the power button until the power off prompt appears.
Enter Safe Mode: Touch and hold the “Power Off” icon until the “Safe Mode” option appears, then tap it.
Wait for Restart: Allow your device to reboot; you should see “Safe Mode” displayed in the corner of the screen.
Observe Behavior: Use your phone in Safe Mode to determine if the restarting issue stops.
Identify Problematic Apps: If the phone remains stable, suspect third-party apps as the cause and consider uninstalling recent apps.

3. Clear the Cache Partition

Clearing the cache partition can remove corrupted temporary files that might be triggering the restart loop.

Power Off Completely: Turn off your Samsung Galaxy entirely.
Enter Recovery Mode: Press and hold the Volume Up, Home, and Power buttons simultaneously until the recovery menu appears.
Navigate to Cache Wipe: Use the Volume buttons to highlight “Wipe Cache Partition” and press the Power button to select it.

Reboot the Device: Once the process is complete, select “Reboot System Now” and check if the restart loop is resolved.

4. Uninstall Recently Installed or Updated Apps

Newly installed or recently updated apps can sometimes conflict with system processes and cause unexpected restarts.

Boot into Safe Mode: Follow the steps in Method 2 to start your device in Safe Mode.
Open Settings: Navigate to the “Apps” section within the Settings menu.
Review Recent Apps: Identify any apps that were installed or updated just before the restarting issue began.
Uninstall Suspect Apps: Select each suspect app and tap “Uninstall.”
Restart in Normal Mode: Exit Safe Mode by restarting your phone normally and monitor its behavior.

5. Remove the SD Card

A faulty or incompatible SD card can cause system instability and may lead to continuous restarting.

Power Off the Device: Turn off your Samsung Galaxy completely.
Locate and Remove the SD Card: Eject the SD card from its slot safely.
Restart the Phone: Power on your device without the SD card inserted.
Monitor Performance: Check to see if the device continues to restart.
Troubleshoot Further: If the issue stops, consider backing up the SD card data and formatting or replacing the card.

6. Check for Overheating and Battery Issues

Excessive heat or battery malfunctions can cause system instability, resulting in unexpected restarts.

Assess Device Temperature: Feel your phone to determine if it is unusually warm; if so, allow it to cool down before use.
Avoid Intensive Tasks: Limit the use of resource-heavy applications during charging or high ambient temperatures.
Inspect the Battery: For devices with removable batteries, remove the battery and check for signs of damage or swelling.
Use Recommended Accessories: Ensure you are using the charger and accessories recommended by Samsung to avoid power-related issues.
Monitor Behavior: After taking these steps, restart your device and observe if the issue persists.
