There’s a problem with Android screens that seems to crop up when you least expect it, and it’s too annoying to ignore. I’m talking about your screen flashing, flickering, or blinking in and out at seemingly random times. It’s more than just annoying, it gets in the way of doing anything on your Android, but you can still fix it.
There are a few different possible reasons for the flickering, but each one has a fix. These steps won’t take long to get through and are repeatable if the problem ever happens again. With luck, after you’re done following these steps, you’ll never have a flickering screen problem on your Android past today.
1: Restart Your Android
This is what I always say to do when troubleshooting anything, and there’s a good reason for it. A quick restart fixes most software problems with anything, not just Android devices.
Power your Android down completely, and then wait at least fifteen seconds before powering it on again. If your screen flickering problem only happens occasionally, it’ll be hard to tell if this did the trick. Give the step below this one a shot, even if you think you’ve fixed the problem here.
2: Changing Developer Options
After a quick restart, take a look at your Android’s developer options. You’ll find them near the bottom of your Android’s Settings menu. If you don’t have the option, you’ll have to grant yourself developer access.
In your Settings, scroll down to About phone or About device.
From there, go into that section, and scroll down to your build number. Tap it about six times or more, and you’ll get a message telling you that you now have developer access.Go back to your Settings menu, and you’ll now have a Developer options menu to use. Go into your new options and scroll all the way down to the Drawing section.
If you have the Show surface updates switch enabled, disable it. Then go down one more section to Hardware accelerated rendering until you see the option for Disable HW overlays.
Enable the option so your Android only uses your GPU for screen compositing. Screen flickering happens when your Android switches between GPU and CPU for the same job, but enabling this eliminates the choice, and gets rid of the flicker.
3: Manage Your Brightness
If your screen is still flickering, take a look at your brightness settings. You’ll find them under your Display settings. First things first, disable auto-brightness correction or adjusting.
Next, if you experience the flickering with low brightness, use a higher setting, and vice versa. You’ll start to notice a difference immediately. Either the flicker will disappear, or it’ll become more noticeable, meaning the problem has to deal with a deeper issue.
4: Ruling Out Software Problems
Do some troubleshooting to make sure the flickering is a problem with your Android’s software, instead of hardware. We’ve gone over everything you need to do to start troubleshooting, so please take a look to stop the flickering once and for all.
If the flickering still happens after that, there isn’t much more you can do on your own. Consult your warranty, or take it in for repairs at a local store to see what you can do for a replacement or a fix. If this is a known problem for your Android model, you’ll need specific help.
Unless faulty or damaged hardware is causing the problem, any of the above steps will stop your screen flickering once, and for hopefully all. It’s one of the more annoying problems on Android but thankfully is easy enough to fix with enough time and patience.
