This article includes easy-to-follow solutions so you can bring your screen back to normal and keep it smoothly working. Read on and get your iPhone screen working as expected.

Causes of iPhone Screen Flickering

Most of the time, your iPhone will not notify you when an error occurs on its system. You need to see the device's physical state where the function malfunctions. You can pinpoint the error immediately for iPhone screen flickering issues, as blinking lights on your screen are not expected for iPhones. An obvious indicator that your device has this is the green pigment on its screen. How does this error occur on your screen? There are two factors why your iPhone is having this problem. The first one is the software-related factor. When you are doing modifications like jailbreaking, you give your device an option to install software and settings that are not permissible by Apple developers. This is a great option/feature when you need to install applications that are not found in the App Store. However, this process can make your system vulnerable to bugs, glitches, and even virus infiltration that will cause iPhone screen issues. Another reason your iPhone is having a problem is hardware-related factors. When your device gets dropped in high places, smacked with hard things, or squished in rough objects, there is a chance that your screen will be damaged. Having a faulty screen will make your iPhone emit green flickering lights.

8 Ways to Fix iPhone Screen Flickering Lines

1. Disable Auto-Brightness

When your device is flickering its screen without any external damage, check its internal features to see if they cause the issue. One of the display features that the iPhone contains is its auto-brightness option. When enabled, the device will automatically adjust lights according to the phone's environment. For instance, when you go outside on a sunny day or summertime, your device's brightness will adjust once it recognizes the high-light concentration around it. It will make your screen readable whether you are outside. Similarly, when your device enters a dark room, it will automatically reduce the light it emits to adjust for the user's eyesight. It is indeed a functional option to have. Yet, when system bugs suddenly seep into your iOS system, it can make this feature malfunction, and a flickering light will appear. What you can do to reset the function of auto-brightness is to turn it off to prevent your screen from having flickering lights. Check the listed methods below to learn how to disable this feature on your iPhone.

• The initial process to turn off the auto-brightness is to unlock the iPhone device. Access the home screen layout and check for your pre-installed applications. Tap on the Settings app with the gray gear icon from the list of apps.
• Next, from the list of settings, scroll down on your screen and tap Display & Brightness. A new set feature will appear on your screen. Check the Automatic option if it is enabled.
• If so, tap the green button to turn off the feature. Check your device to see if a green color is still flickering on its screen. Continue using your device to check if the error will reoccur.

2. Turn Off HDR Mode

Another reason why your iPhone is having an issue with a flickering screen is due to malfunctioning HDR mode. How does this feature affect your screen, and what does it do? HDR mode is a function for iPhone cameras that provide a range of dark and light tones in your photos. It is used to get the perfect amount of shadow and light for your photos. Unlike the human eye, mobile cameras do not have a high dynamic range to check details in both highlights and shadows. That makes HDR essential to have or enable on your iPhone device. The iPhone display flickering may be caused by HDR mode when you open your mobile camera. How is that? Your iPhone display cannot simultaneously provide a better refresh rate for photos with HDR features, making your device flicker when browsing your photos app. Some users reportedly fixed the flickering lights on their devices when they turned off the HDR mode. To understand how to deactivate it on your iPhone, follow the guide below.

• Begin the process by unlocking your device and accessing your home screen layout. From the list of your applications, find the Settings app. Tap on the gray gear icon to launch the menus.
• Then, scroll down on your screen and locate the Camera app from the list. Tap on its icon to launch a new landing page. Check the Auto HDR option if it is enabled.
• If so, hit the green button to toggle it and turn off the feature. Then, check and access your pictures on the Photos app. See if the flickering light persists while browsing on your screen.

3. Close/Uninstall Application

This solution is situational, yet in some cases, it is effective. When your device experiences glitching for a specific application you have installed on its system, check if the app is safe or updated. For example, you installed TikTok a month ago and turned off its automatic updates. Eventually, you access it, and your device starts to flicker and glitch; it might be due to its outdated program. You must access the App Store and update the application. Another reason why the specific app has flickering issues when using it is because of software bugs. Too much and constant usage of specific apps and allowing them to function in the background will make them glitchy and malfunction. Make sure to refresh or close each app you use whenever you exit their functions. Lastly, uninstall when you accidentally install an app with a suspicious source and the screen starts flickering. It might contain harmful firmware that can damage your mobile phone. To do this, long-press the application and hit the Remove App icon to uninstall it on your device.

4. Force Restart iPhone

When you have assessed your device, and it becomes glitchy due to RAM consumption and minor bugs, you have to restart it.

An outdated iOS device is vulnerable to software glitches as some functions applied on the current patches will not work correctly with older iOS versions. It will compromise the performance and process of your device. When it persists, it can damage most of your display activity. Apps can freeze, and the iPhone screen can emit weird glitches of lights flickering on its display. In addition, if the general public has flashing lights caused by a system bug, Apple developers will add firmware on their iOS patch notes which will address the issue.
