Maintenance
1. Water Resistance

2. Screen Care
To maintain the integrity of your foldable screen, avoid pressing the screen or front camera lens with hard or sharp objects. Only use a Samsung S Pen Pro or S Pen Fold Edition. When folding the phone, ensure no objects are inside that could damage the screen. Do not remove the protective film on the main screen or apply unapproved films or stickers, as this may cause damage.
3. General Cleaning
Regularly wipe your device with a soft, lint-free cloth. Avoid harsh chemicals or abrasive materials that could scratch the screen or body.
Troubleshooting
Common Issues and Solutions
- Screen Cracking/Dead Pixels: Some users have reported issues with the middle screen developing cracks or dead pixels. While this can occur with foldable technology, ensure you follow all screen care guidelines. If the issue persists and is not due to misuse, contact Samsung support for warranty options.
- Phone Not Charging/Turning On: Ensure you are using the original USB cable and a compatible charger. Check the charging port for any debris. If the phone does not turn on, try a forced restart by holding the power and volume down buttons simultaneously for about 10 seconds.
- Locked Phone (Service Provider): If your renewed phone is advertised as "unlocked" but remains locked to a specific carrier, contact the seller or the carrier directly to resolve the unlocking issue.
- Apps Crashing When Folding/Unfolding: Some apps may not be optimized for the foldable screen transition. Ensure all your apps are updated to their latest versions. If an app consistently crashes, try reinstalling it or contacting the app developer.
