Have you ever noticed that when you’re playing games on your Android phone, or just swiping around the home screen, that there’s some kind of flickering on the screen?
It’s incredibly distracting and can even hurt your eyes if you stare at it too long.
Luckily, this problem has an easy fix that can usually take care of it in seconds! Read on to learn How to fix screen flickering Android devices.
What Causes screen flickering on Android
When you first notice a screen flicker, it’s annoying. Over time, though, it can be more than just an annoyance.
For example, if you notice that your Android phone keeps switching between 2G and 3G connections when using data services over your carrier network—even when you’re nowhere near a dead zone—that could be due to damaged LCD connections or bad display drivers. Sometimes glitches are easy enough to clear up with a simple reboot.
Other times, you may need some (sometimes advanced) troubleshooting skills before you can get things working again.
How to fix screen flickering Android easily
Below are the possible fixes for android phone flickering:
Try to Reboot Your Phone
Your phone will sometimes experience a small glitch that makes your screen flicker. The easiest way to fix it is by simply rebooting your phone.
When you reboot, you’re clearing out what little resources are being used and thus allowing more room for things like a flickering screen.
If for some reason that doesn’t work, try restarting your device in safe mode. Safe mode prevents third-party apps from running, which may be causing issues with your display.
Check for the Affected Part of Your Phone’s Screen
If you’re using a Galaxy S8 or an S8 Plus, see if any edges of your phone are flickering. If it is, check for moisture in that area and dry off as much of it as possible.
Then try removing any cases you have on your phone—especially any battery cases, which use their own batteries to power part of your phone.
(Galaxy S8s have been known to be susceptible to water damage when a case has been used.) Once you take off both those things, turn on your screen and see if it still flickers.
If not, but there was moisture under that layer, then water may have gotten into another part of your phone’s motherboard.
Disable Phone’s Auto-Brightness
If your screen flickers at seemingly random intervals, then one possible cause could be an incorrect brightness setting.
If you’re adjusting the brightness manually and aren’t sure how, then here are some instructions: First, go into Settings > Display > Brightness.
From there, simply drag or slide the bar (labeled brightness level) across until it reaches a comfortable level.
If you want to fine-tune things even further, tap Adjust brightness automatically and follow either set of steps below based on whether you use manual or automatic brightness settings.
To turn off automatic brightness, tap Auto brightness.
Boot Into Safe Mode
To boot into safe mode, turn off your phone, wait a few seconds and then press and hold Power + Volume Down.
Continue holding both buttons until you see Safe Mode in black letters on top of a screen that’s fully white.
It’s normal for the safe mode to look slightly different than the normal mode—things might be bigger or smaller, or buttons may be in different places.
Safe mode is exactly what it sounds like: no third-party apps are running so if there’s a problem with an app, you can rule that out as being responsible for any issues you’re experiencing.
To boot out of safe mode, follow these steps again and choose Reboot.
A hard reset might be required
If you are experiencing problems with your smartphone, a hard reset may help bring everything back in order.
This process will erase all of your information and settings, however, so it’s important that you have a backup of all data before proceeding.
If you do not have a backup and can’t afford to lose any personal data (or don’t want to waste time creating one), do not try a hard reset; rather, contact customer service for help troubleshooting first.
Also, know that performing a hard reset is different from doing a factory reset or even flashing custom ROMs—and may or may not solve problems.
A factory reset is more like putting your phone into safe mode—it boots up without any apps running in the background.
A factory reset will also erase all of your data, so you’ll need a backup of any important information.
Try clearing the cache
Sometimes, when you install too many apps or have several apps running in the background, your phone might start to slow down and freeze.
One of those signs is a flickering display—an annoyance that can be easily fixed by clearing your phone’s cache. Clear cache data from Apps under Settings > Storage > Cached Data.
Tap OK if you see a prompt from Storage Cleaner (in Lollipop and above) or SD Maid (in KitKat).
When you see This may take some time at the bottom of your screen, wait until it says Cleaning complete before continuing. Clear cache data from Settings under More > Storage > Cached Data.
Disable Hardware Overlays
Overlays are a handy tool in many ways, but they can cause trouble when it comes to touchscreen responsiveness.
For example, if you’re trying to play an active 3D game and run into glitches as you tap away at its virtual controls.
Rather than fight with your phone or tablet about it, simply turn off its hardware overlays by heading into Settings>Accessibility>Sensors (on stock Android) or System Settings>Displays (on Samsung phones).
There you’ll find an option for Adjust touch sensitivity and should disable it. This will help eliminate pesky ghosting from happening and make multi-touch gestures like pinch-to-zoom more accurate across all of your apps.
Hopefully, with a little help from you, your touchscreen will be touch-perfect in no time.
Manage The Developer Options
The developer options are settings that are hidden by default, but they’re extremely useful for troubleshooting issues with apps.
So before you try anything else, it’s worth checking if you can fix a problem with them. You’ll find them in Settings > About Phone (or just ‘About’ if you’re running Android Nougat or newer).
Scroll down until you see Build Number and tap it seven times. This will enable developer mode and pop up a message saying so.
Keep tapping ‘Build Number’ until it says You are now a developer! This will reveal a new section at the bottom of Settings called Developer Options.
Tap back up to get there, then scroll down again and turn off Window Animation Scale, Transition Animation Scale, and Animator Duration Scale.
Check for Device Updates Available
Flickering is often caused by an outdated software version. An OS update could be all that’s needed to solve it, so check and install any available updates.
If you’re not sure how to do that, refer back to our section on checking for software updates and use those same steps.
Even if there aren’t any updates available yet, it doesn’t hurt anything to check every now and then just in case.
We’ve seen new fixes roll out as quickly as a few days after their availability was announced. Keep checking back, especially if you continue experiencing flicker issues after installing your last update.
While we’re talking about updating, it’s a good idea to do so as often as possible. Updates can include new features and bug fixes that will make your device run more smoothly and last longer.
but what if any of these tips don’t help, then it’s required you reach out to a professional repairer.
