iPhone 17 Pro Screen Flickering or Flashing?
Screen flickering on the iPhone 17 Pro can range from a subtle flicker you notice in low light to a severe rapid flash that makes the phone unusable. On OLED displays like those found in the iPhone 17 Pro, flickering is often caused by panel degradation, a damaged display driver IC, or a partially disconnected flex cable. In some cases an iOS update can trigger display driver bugs, but hardware causes are more common when flickering persists after a software update.
