Why does my Flip 4 screen stop coming back on after I close it?

I’ve been having a frustrating issue with my Samsung Flip 4. Every time I close the device, the screen refuses to turn back on when I reopen it. Initially, I thought it might be an intermittent problem, but it has become a persistent issue. I’m not sure if it’s a hardware fault or a software glitch that’s causing this. Sometimes, I hear notifications coming through, so I know the phone is still functioning, but the display remains stubbornly black. This problem makes it really difficult to use my phone on a daily basis. I’ve tried different ways to troubleshoot it on my own, such as pressing the power button multiple times and even restarting the device, but nothing seems to permanently solve the issue. I’m hoping to find out if anyone else has experienced this problem and what steps I should take to address it.

Experiencing screen issues with your Flip 4 can be incredibly frustrating. Here’s a detailed approach to tackle this problem, garnered from various community forums and personal experience:
- Inspect Physical Damage: Start by carefully inspecting your device for any physical damage that might have occurred to the hinge or the screen. Sometimes, even minor impacts can disrupt the functionality.
- Battery Check: If the phone remains responsive but the screen stays off, consider checking the battery. A malfunctioning battery or power supply can lead to such issues. Charge your phone using a different charger to rule out power-related problems.
- Third-party Apps: Disable any recent apps installed before the issue began, as some apps might interfere with the normal functioning of the display.
- Developer Options: Enable Developer Options by pressing ‘Build Number’ in the ‘About Phone’ section of settings multiple times. Then check ‘Stay Awake’ under Developer Options. This doesn’t fix the issue directly but helps to monitor if the screen turns on while charging.
- Manufacturer Support: Contact Samsung support since the issue could be a defect covered under warranty. They may offer a free repair or replacement if the phone is still under warranty.
By following these comprehensive steps, I managed to resolve my screen issue effectively without having to opt for immediate hardware repairs.

I faced a similar issue and resolved it by taking the following actions:
1. Hard Reset: Initially, I performed a hard reset by pressing the power button until the device restarted. It didn’t solve the issue initially, but occasionally, it would give temporary relief.
2. Visit a Certified Technician: Realizing the problem might be more significant, I visited an authorized Samsung service center. The technician ran diagnostics and identified a defective display module, which they replaced under warranty.
3. Keep Device Software Current: Post-repair, I continually make sure my device runs the latest firmware. Regular updates can patch issues and enhance performance.
My advice would be to opt for a professional check-up early on if basic troubleshooting steps don’t yield lasting results.

Encountering such issues can be troublesome, but here’s how I tackled it effectively:
- Reset Settings: In your settings menu, navigate to ‘General management’ > ‘Reset’ > ‘Reset all settings’. This doesn’t delete your personal data but will reset all settings to their default, which might resolve software-triggered issues.
- Battery Optimization Settings: Ensure that any battery optimization settings aren’t causing the screen to stay off. Go to the device care menu and disable battery optimization for essential apps.
- Samsung Members App: Utilize the Samsung Members app to run a diagnostic test. This app can often pinpoint issues with your device that aren’t apparent through normal use.
- Warranty and Repairs: Should the problem persist, check your warranty status and consult with Samsung support for potential repairs or replacements if software fixes don’t help.
These steps have been a lifesaver and helped me manage the screen issue effectively on my Flip 4.

I had a similar issue with my Samsung Flip 4, and here’s what worked for me:
1. Soft Reset: I first tried a soft reset by holding down the power and volume down buttons simultaneously for about 10 seconds. This forced a restart without losing any data.
2. Check for Updates: I ensured my software was up to date. Sometimes, these problems can arise due to outdated software versions.
3. Safe Mode: I booted my phone in safe mode to determine if a third-party app was causing the issue. To do this, I held the power button until the Samsung logo appeared, then held the volume down button until it restarted. This temporary mode disables third-party apps.
4. Clear Cache Partition: Accessing the recovery menu and clearing the cache partition also helped. After turning off my phone, I held the power, Bixby, and volume up buttons simultaneously until the Samsung logo appeared. Then I navigated to clear the cache partition using the volume buttons and confirmed it with the power button.
5. Factory Reset: As a last resort, I performed a factory reset. I backed up my data first as this process erases everything on the phone. This was done through the settings menu under “General Management” > “Reset” > “Factory Data Reset”.
These steps addressed my issue effectively.
