If your iPhone screen flickers even after doing the previous solutions, then your last resort, at least before bringing iPhone to the tech, is to reset it. This time though, you need to create a backup of things you don’t want to lose, or you can simply sync your iPhone with the iCloud.

If your iPhone screen is flickering after this, then you can try restoring it by booting it up into the DFU mode (Recovery Mode) and restoring it using iTunes on Windows PC or Finder on Mac.

But at this point, if the problem continues, we suggest you have it checked. It’s a possible hardware issue.
