"I have an iPhone X, bought less than a year ago. Everything works fine except for one issue: screen randomly goes black , but the phone doesn't turn off. When I press the lock button, the screen locks, and after unlocking, it works normally again. This keeps happening at random intervals. What could be causing this iPhone screen to go black randomly, and how can I fix it?"

iPhone screen goes black randomly

The problem that the iPhone screen goes black randomly during normal use is bothering many people. According to some users, this problem happens when turning the iPhone into landscape orientation, opening certain apps, end a calling, or a few minutes after unlocking. So, what's the reason behind this problem and how to fix it?

Notice:

If your iPhone hasn't experienced a drop, hit, water damage, high temperature, or screen replacement, then this problem is probably caused by software glitches. So, you can take the following methods to fix the problem and stop your iPhone screen from going black randomly.

Way 1: Force restart the iPhone
Way 2: Free up storage
Way 3: Update iOS software
Way 4: Fix iPhone with iSumsoft iOS Refixer
Way 5: Restore iPhone to factory settings

Force restart the iPhone

When your iPhone encounters some minor problems (like the screen going black randomly) but still works, force restart (or hard reboot) is the first solution you should try. A forced restart will close all running apps, release memory, and refresh the system. This helps repair some problems and won't cause any data loss on the device. To force restart your iPhone, follow the steps below according to your model.

iPhone 8/later Press and release the Volume Up button. Press and release the Volume Down button. Then press and hold the Power button until the Apple logo appears.

iPhone 7 Press and hold the Power and Volume Down buttons at the same time until the Apple logo appears.

iPhone 6s/earlier Press and hold the Power and Home buttons at the same time until the Apple logo appears.

Free up storage

Insufficient storage may also cause the iPhone screen to go black randomly. So, go to Settings > General > iPhone Storage to check your remaining storage. If you have less than 3GB of storage left, clean up unnecessary contents and temporary files to free up the iPhone storage space. Then observe the iPhone for a while to see if the black screen problem has been fixed.

Update iOS software

If you have tried the above two methods, but the random black screen problem persists, then chances are that your iPhone is having a system fault. Updating the iOS software may fix the problem.

Step 1 Go to Settings > General > Software Update.

Step 2 iPhone will start checking for update and then display the latest iOS version on the screen.

Step 3 Tap Download and Install to start updating the iPhone.
