16 Ways To Fix A Galaxy S24 Ultra That Keeps Rebooting

Your Samsung Galaxy S24 Ultra is designed to deliver seamless performance, but frustratingly, unexpected and repeated restarts can make the device unusable. Various factors can cause these reboot loops, from problematic software to potential hardware defects.

Why does my Galaxy S24 Ultra keep rebooting?

  • Software glitches: Conflicting apps, corrupted system files, or bugs in either the operating system or individual apps can lead to software conflicts and system instability.
  • Overheating: Excessive heat can trigger safety mechanisms within your device, forcing it to reboot in order to cool down.
  • Faulty hardware: Issues with the battery, motherboard, or other internal components can cause malfunction and random restarts.
  • External storage problems: A damaged or corrupt SD card, if used, can lead to system crashes and boot loops.
  • Liquid damage: Even minor moisture entry can disrupt internal components and lead to hardware faults, resulting in a boot loop.

1. Force restart your device

Sometimes, a forced restart can break a reboot loop caused by a temporary glitch.

  1. Press and hold the power and volume down buttons simultaneously.
  2. Hold these buttons for about 10-15 seconds, even if the screen goes black.
  3. Release when the Samsung logo appears.

2. Remove recently installed apps

Incompatible or buggy new apps can lead to conflicts and cause restarts. Uninstall any apps you’ve downloaded just before the problem arose.

  1. Open Settings -> Apps.
  2. Sort apps by recently installed and uninstall apps added just before the problem started.

3. Clear App Cache and Data

Corrupted app cache and data can contribute to instability. Clearing this data is often helpful.

  1. Access Settings -> Apps.
  2. Tap on individual apps, particularly those used heavily.
  3. Go to Storage and utilize the Clear Cache and Clear Data options.

4. Uninstall or update specific problematic apps

Identify misbehaving apps via memory errors, frequent crashes, or known problems. Remove these apps or update them if fixes are available.

  1. Check recent app updates for known issues related to restarts.
  2. Look for crash reports in device maintenance if your Android system includes logs.

5. Boot into Safe Mode

Safe Mode is a diagnostic environment loading only core Android software. If your S24 Ultra works flawlessly in Safe Mode, a downloaded app is likely the cause.

  1. With your device on, press and hold the power button.
  2. Tap and hold the Power off icon displayed on your screen.
  3. When a Safe Mode prompt appears, tap OK to restart.

6. Check for OS updates

Software updates often include bug fixes and stability improvements. Keeping your software current can minimize problems.

  1. Go to Settings -> Software Update.
  2. Select Download and Install if an update is available.

7. Remove case and check for overheat

Some overly insulating cases can cause overheating. Temporarily remove your case and watch for signs of thermal instability (sudden restarts or abnormally high temperatures).

8. Check for physical damage

Drops, impacts, or bending can damage internal components and lead to boot loops. Inspect your device for signs like cracked screens or a distorted chassis.

9. Check for signs of water damage

Moisture damage can trigger various errors. Look for discoloration of the Liquid Damage Indicator (LDI) which is typically found within the SIM tray on Samsung devices.

10. Disable Auto-Restart settings

Some Samsung devices have an “Auto Restart at scheduled times” feature. Ensure this is disabled as it could perpetuate restart problems.

  • Access Settings -> Battery and Device Care or similar power management settings.

11. Optimize Power & Battery settings

Aggressive battery-saving modes can hinder normal function. Customize the battery optimization settings of your device and see if performance and stability improve.

  • Find power management options under Settings -> Battery and Device Care.

12. Contact Samsung Support

If restarts persist after these steps, Samsung’s experts have resources for advanced troubleshooting, remote diagnostics, and repair coordination. They might uncover issues requiring firmware fixes or specialized assistance.

13. Perform a factory reset

This action clears all user installed data and apps, reverting your phone to “like-new” settings. Before initiating a reset, create backups of all personal data!

  1. Locate Settings -> General Management -> Reset.
  2. Select Factory Data Reset and follow the on-screen instructions to start the process.

14. Check device diagnostics / hardware status

Some newer devices might include device diagnostics in their settings menus. Utilize features like phone status checks or hardware tests if they are available, as these provide clues for troubleshooting internal components.

15. Seek assistance at a Samsung-certified repair center

These experts can diagnose device hardware faults, provide specialized testing for underlying issues, and replace defective components (if needed) using genuine replacements. This should be considered especially if hardware damage is suspected.

16. Check if warranty replacements are available

In certain cases, manufacturers offer warranty-covered replacements for defective devices. Contact Samsung and explore the eligibility of your S24 Ultra for potential warranty service.

Final thoughts

By navigating this thorough list of solutions, you will likely resolve the frustrating reboot loop issues on your Galaxy S24 Ultra. If persistent restarts occur even after exhausting the steps listed, seeking evaluation from experienced Samsung technicians is generally the next step.
