It is such a bummer because users are expecting a lot from such a hefty device but only to end up facing with such troubles.

Cases like this are usually isolated on certain apps, which is the camera app. Perhaps, the app has crashed or there are some corrupted files have affected the program functionalities, which resulted to this symptom.

Other owners of the iPhone 7 Plus have also noticed some flickering display when exposed to artificial light while using FaceTime in making video calls. Some have it that their iPhone’s front camera also flickers during the video recording.

Screen flickering or frozen display are not supposed to happen on such a highly powerful device but many experts have speculations that poor software optimization by Apple has somehow triggers such downsides to manifest on the iPhone. Just like what many users have complained on the iPhone 6s Plus model, which was said to utilize a hardware based downscaling algorithm instead of optimizing software. But then again, this must not be the case with the new iPhone 7 Plus considering the fact that it is the company’s latest model and so it must already have been refined.

Software updates are also named among the culprits. For some reasons, some firmware patches have caused similar problems to occur on some iPhone variants after implementation.

  • Drag the slider to turn your iPhone completely off.
  • After 30 seconds, press and hold the Power button again until you see the Apple logo.

Your iPhone should then reboot and hopefully erased the symptoms.

Step 2. Enable Reduced Transparency

For some users who have experienced the same issue in which the iPhone 7 Plus screen flickers or shows white lines or huge white boxes while pulling down notification, they have resorted to a temporary workaround which is to enable the Reduced Transparency feature on their device. To do so, head over to Settings-> General-> Accessibility-> and then toggle the switch to turn on Reduced Transparency.

You too can use this workaround while waiting for Apple to officially rollout a fix on the next iOS update for this software issue. Other iPhone 7 Plus owners who have encountered the same problem on their new iPhone screen were able to obtain temporary fix by changing the font size to any other size except for the smallest. So you might as well consider giving this trick a try on your end.

Step 3. Disable iCloud Sync for iWork on your iPhone

If the screen problem occurs while using certain apps on your iPhone including Pages, Numbers or Keynote, then you may try to disable iCloud Sync for iWork on your device. Other users reported that their iPhone crashes, shows blue screen and reboot when they pressed the Home button while editing a document using any of these apps.

Step 4. Restore your iPhone to factory settings via iTunes

A system restore often resolves problems that are triggered by software bugs or glitches. This method will erase all data on your iPhone and restore it to factory settings.

Then, continue with these steps:

  • Connect your iPhone to the computer using the supplied USB cable.
  • Open iTunes on the computer.
  • In the iTunes Summary panel, select the option to Restore.

Once the restore process is complete, your iPhone is set up as new and see if the problem is now gone. You can manually bring data back to your iPhone using iCloud or iTunes but as much as possible, do not restore from the previous backup because there is a higher chance that the issue may re-occur especially if it was due to some corrupted files or contents.

Step 5. Use alternative solutions to restore your iPhone

There are a lot of well-known freeware like ReiBoot, which you can use to fix system issues in an iPhone device including those that are manifested by screen flickering and unresponsive touchscreen symptoms.

How to fix screen flickering problem while using the iPhone 7 Plus camera app?

Here are a few recommended workarounds you can try on if your iPhone screen flickers while using the camera application.

Step 1. Turn off Portrait Mode

For optimal results, try to keep your subject as simple as you can, given the Portrait Mode is still in beta. Head over to your iPhone Settings-> Photos & Camera, and then scroll down to enable the option to Keep Normal Photo. Turning off Portrait Mode will reduce the flicker sensor factor while focusing on people face and object borders in video calls.

Step 2. Disable 60 FPS video recording option

Generally, an iPhone records video at 30 FPS (frames per second) by default. But newer models like the iPhone 7 and 7 Plus support video recording at a silky smooth 60 FPS at 1080p (full) resolution. With this option set on your iPhone 7 camera app, you can expect a very smooth high frame rate video output. But for some reasons, some units are showing screen issues while activating this option. As temporary solution, you can try to disable this high frame rate video capture mode to deal with the flickering problem while waiting for a definite fix from Apple.

Step 3. Update to iOS 10.2

The latest iOS version available to date is iOS 10.2 beta. If you haven’t yet updated your iPhone 7 Plus iOS, then you may do it now. Aside from new add-ons and performance enhancements, the most recent iOS version also contains fix patches to certain bugs found in the existing platform.
