Recently, the device received a One UI 5.1 update based on Android 13. However, some users have reported experiencing a black screen or black-and-white line on the screen while using their phones. Of course, this doesn’t apply to all the units out there, but a subset of users are facing the same issue.

It turns out that when your phone has a black screen issue, it tends to vibrate and even works, but the screen is off, so you can’t see what’s happening. If that’s something you are facing, check out the guide on what’s termed a Samsung Z Fold 3 black screen issue and how to fix it.

What is the Samsung Galaxy Z Fold 3 Black Screen Issue?

If you encounter a black screen issue with your Samsung Galaxy Z Fold 3, it may happen unexpectedly. In this case, the phone’s screen will remain black or blank, even though you can hear some sound or feel the phone vibrate when you press a button. Although the phone may receive notifications and make sounds, it will not respond when you try to interact with it.

There can be a tonne of reasons why you are facing Samsung Galaxy Z Fold 3 black screen issues. This includes loose LCD connectors, incompatible apps running on the system, battery overcharging, app cache causing issues, or the phone could be subjected to extreme heat. Of course, these aren’t the only causes of the issue and there are many others to cope with.

How To Fix Samsung Galaxy Z Fold 3 Black Screen Issue?

#1: Whether the power button are jammed

The power button on your Samsung Galaxy Z Fold 3 allows you to lock/unlock/turn on/turn off the phone. It turns out that the power button is jammed at a pressed position due to dirt, lint, or other debris.

You can press the power button consecutively to free the button and probably fix the black screen issue.

#2: Check for any liquid or physical damage

Both physical and liquid damage on your phone can cause black screen issues as the water or fall might have affected the display apart from other components. For liquid damage, you can check out the liquid damage indicator (LDI), which will turn to pink or purple upon interacting with the water.

Check for traces of water if there’s liquid damage. In case of physical damage, check out if the display is broken, as that may pose a problem. In these cases, you must report the issue to a nearby authorized service center to get the display repaired or replaced.

#3: Did you inspect the charging port?

It turns out the Samsung Galaxy Z Fold 3 black screen issue could be as simple as the fact that your battery has died, and the debris inside the charging port is what prevents you from charging the battery. Have a look inside the charging port. Use a torch to peek inside. Use a needle or a toothpick to remove unwanted debris, although do not pierce it too much as it will damage the pins inside.

#4: Your battery has discharged

Yep, that could be a thing. The battery has discharged well beyond the phone, which could vibrate when you press the power button, but the display won’t light up. If you continue to press the power button, hoping that the phone will start, it will drain the battery even further.

Connect your phone to the charger and idle it for 10-15 minutes. This should charge the phone’s battery sufficiently for it to turn on.

#5: Remove the battery

Samsung Galaxy Z Fold 3 doesn’t have a removable battery; however, if you refer to this guide for other Samsung or Android devices with a removable battery, try removing it. Wait a few minutes, then put the battery inside and check whether this makes any difference.

#6: The display connector could be loose

Have you ever come across videos by iFixit or JerryRigEverything? They demonstrate that the phone’s display and other components are connected to the motherboard using a Lego connector. However, this connector can become loose, causing the display to disconnect from the motherboard.

Since the phone is still working, you should be able to receive calls and notifications and maybe interact with the display. Still, as the display is not showing anything, you are trying to hit a goal blindfolded. If the reason behind the Samsung Galaxy Z Fold 3 black screen issue is a loose connector, a technician can fix the issue simply by reseating the cable.

An authorized service center can do it while keeping the phone’s warranty intact, while a locate center would void it. You can even do it yourself, although I wouldn’t recommend it unless you have the expertise to do it without breaking anything.

#7: Perform a force reboot

In light of critical system errors, a force reboot can work wonders. Here’s how it works.

For Samsung smartphones, you can use the power plus home plus volume Up/Down buttons to trigger a forced reboot. Another way is to press the home and power buttons together. The

#8: Clear cache

There are multiple ways you can clear cache files. You can go to Settings >> Apps >> Tap on an app >> Storage >> Clear Cache. On the contrary, you can go to the recovery mode and perform “Wipe Cache Partition”. This assumes that the phone’s screen is working and you can interact with the device.

#9: Reach out to a technician

Certainly, the last resort is to seek help from a technician whether the black screen issue is due to hardware or software errors. You have options between a Samsung authorized service center or a local one so you can choose. The goal is to find a fix and get the phone working as usual.
