Why is my Apple iPhone 6s Plus screen flickering or showing other unusual display problems? [Troubleshooting Guide]

When it comes to users’ complaints, display issues such as black screen, red screen, screen flickering and other unusual displays appeared to be among the widespread problems affecting the Apple iPhone 6s Plus device.

Actually, cases of screen flickering faults have already been seen in prior iPhone models, particularly on the iPhone 6 variant. At that time, a common concern raised was about a grey line that flickers on the iPhone screen, which was later on found out to be a design fault involving two touchscreen controlled chips or Touch ICs on the logic board inside the phone. The problem was popularly tagged as Touch Disease which has broken tons of iPhone 6 and 6 Plus models. Apple has later acknowledged the problem and responded by launching a Multi-Touch Repair Program to address the problem. It was supposed to be resolve at that time.

However, when the next iPhone models came out, many users were still complaining about the same display issue on their iPhone screen that flickers. It seems that the problem has become widespread among iPhone 6s Plus models.

If you are among those who are still plagued with the same screen flickering or other unusual display symptoms on the same iPhone, then you may refer to this content as it highlights some potential solutions and recommended workarounds you can use to deal with the problem before setting up for a tech visit and pay for a hefty service fee.

Common factors that can cause your iPhone 6s Plus screen to flicker

Majority of user complaints about flickering display on an iPhone are linked to a faulty hardware component. This is usually the case when it comes to prior iPhone models with several years of usage. But this is not always the case. Other users who have encountered the same issue on their respective iPhones have found out that a certain faulty app was the root-cause, and thereby denotes that the problem was software-related.

There are times when an application encounters random errors or problems, which can likewise affect certain features and functions of the phone. An application can misbehave after installing buggy updates or adding corrupted contents. Sometimes, the same problem can occur after making a few changes to the apps settings, particularly those that are associated with display functions or screen resolutions. For example, when you’ve set a wrong option for certain apps display functions and then screen symptoms began to show after saving the most recent changes you’ve made to that application.

Some iPhone 6s Plus users have noticed similar display abnormalities, particularly screen flickering and visible grey line on the upper portion of the iPhone display. Purportedly, these symptoms usually show up while switching between various camera modes when taking photos or recording a video with the iPhone 6s Plus camera app. In fact, other users were complaining about the front camera that flickers while recording a video. Apparently, these cases of screen flickering are isolated to the camera app. Perhaps, it’s a glitch or some settings configuration that needs to be rectified. Exposure to artificial lights while making video calls via FaceTime can also yield similar screen flickering problem to occur.

Meanwhile, some experts speculate that these display problems are downsides that are more likely triggered by the company’s poor software optimization on the iPhone 6s Plus variants. According to pertinent sources, Apple has implemented a hardware-based downscaling algorithm rather than optimizing the software on this iPhone.

Another factor that can trigger the same display issues to occur on your iPhone is a buggy

software update including major iOS platforms released by Apple periodically.

A series of blue, green, red, and grey lines or flickering white vertical lines can also manifest from screen settings configuration. Just like what usually happens when you’ve set a computer screen to the highest resolution available which the hardware or software couldn’t actually render. The same thing can likewise occur to mobile devices. Although it is unlikely to occur in highest-tiered smartphones like the iPhone 6s Plus, it is inevitable especially with the presence of software bugs or worst, damaged screen components. Aside from the promising new features and software enhancements, software updates especially the major ones can also contain some bugs that can affect certain functionalities on the iPhone, resulting to various symptoms upon implementation.

Memory problems can also cause similar symptoms to show on your iPhone. It is possible that your iPhone 6s Plus is already running low on memory and therefore its overall functionality is no longer at its best. When your iPhone is running low on memory or having insufficient storage, several problems can instigate including those associated with the device performance. Usual indicators of insufficient memory include slow or sluggish performance, apps lagging, random crashes, unresponsive display, and sometimes, inability to render precise display of complex multimedia contents including high-definition (HD) images and videos.

In worst cases, hardware problems are to blame. A presence of damaged component, particularly those within the display circuit board is usually the culprit. This can happen when your iPhone was dropped or got wet. Symptoms may not show up immediately from the actual incident of dropping or exposure to liquid but that does not mean it did not cause any harm to your device. It is possible that the symptoms you are now dealing with are likely indications of hardware damage from previous incidents of hard drop or exposure to liquid. Unfortunately, in the case where hardware damage is to blame, you’ve got no other choice but to set up and pay for service. You can visit the nearest Apple service center in your area or third-party technician for iPhone check-up and repair.

How to fix screen flickering or other display problems on your iPhone 6s Plus?

Screen flickering and other display issues that are software-related can still be remedied with any of the recommended procedures and workarounds. To increase your chances of getting the existing screen problem quickly fixed, try to assess your iPhone and determine what could have possibly caused the symptoms to show up.

Meanwhile, for screen flickering or other display issues while using the iPhone 6s Plus camera app for taking pictures or recording a video, disabling of the Portrait Mode as well as the 60FPS video recording option might be able to fix the problem.

To disable Portrait Mode, navigate to Settings-> Photos & Camera, locate the Portrait Mode switch and then toggle to turn it off. Disabling this camera app option will reduce the flicker sensor factor while focusing on the subject’s face and object boarders in video calls.
