iPhone 16 Screen Flickering? Causes & Fixes

One second the screen looks normal, and the next it is pulsing, flashing, or showing faint stripes of colour. If that is happening on your iPhone 16 or iPhone 16 Plus, the good news is that many cases can be caused by software, display settings, or temporary iOS glitches — not a failing screen.

Note: this guide covers the standard iPhone 16 and iPhone 16 Plus. If you have an iPhone 16 Pro or Pro Max, the ProMotion display behaves a little differently — see our iPhone 16 Pro screen flickering guide instead.

What Causes iPhone 16 Screen Flickering?

The iPhone 16 and 16 Plus use a fixed 60Hz OLED panel (no ProMotion), so the usual causes are a little different from the Pro models:

  • Automatic brightness or True Tone changes — changes in brightness or colour temperature can sometimes make pulsing or display instability more noticeable. Temporarily disabling these features can help isolate the cause.
  • A recent iOS update or software glitch — display behaviour can occasionally change after an update, so installing the latest available iOS version is a sensible troubleshooting step.
  • A misbehaving app — outdated or poorly optimised apps can cause the display to stutter or flash while they are open.
  • Case, screen protector or accessory interference — remove the case and screen protector temporarily and make sure the display is clean and dry. Apple recommends these steps when troubleshooting intermittent screen problems.
  • Physical or water damage — if the flickering started right after a drop or liquid exposure, or if the screen was previously replaced, the display connector or panel itself may be the cause.

Does the iPhone 16 OLED Screen Flicker at Low Brightness?

Sometimes, but it may not be a fault. Like most OLED displays, the iPhone 16 uses pulse-width modulation (PWM) to control brightness, and at very low brightness levels some people can perceive this as a faint flicker — this is normal OLED behaviour, not a defect. Apple’s newer Display Pulse Smoothing feature, which reduces this perceived flicker, is currently limited to the iPhone 17 and iPhone Air line-up and is not available on the iPhone 16. If turning the brightness up removes the flicker entirely, what you’re seeing is most likely this normal PWM effect rather than a fault. Flickering that persists at higher brightness, or that shows as lines or colour patches, is a different issue and worth investigating further.

Software Fixes to Try First (No Cost, No Appointment)

  1. Restart the phone. This alone clears a large share of temporary display glitches.
  2. Toggle Auto-Brightness off, then on. Settings > Accessibility > Display & Text Size > Auto-Brightness.
  3. Turn off True Tone temporarily. Settings > Display & Brightness > True Tone. If the flicker stops, True Tone was contributing.
  4. Update iOS. Settings > General > Software Update — Apple regularly patches display bugs introduced in earlier point releases.
  5. Remove the case and screen protector and check whether the flicker continues without them.
  6. Reset all settings (Settings > General > Transfer or Reset iPhone > Reset All Settings). This does not erase your data, only preferences.

If the flicker only happens in one specific app, the app itself is the more likely cause — check for a pending update in the App Store.

Software or Hardware? A Quick Self-Test

Flickering that comes and goes with brightness changes, specific apps, or after a settings tweak is more likely to be software-related. Flickering that is constant, appears as coloured patches or lines, continues on the Lock Screen no matter what you try, or started right after a drop or water exposure makes a hardware issue more likely — usually the display connector or the OLED panel itself.

Warranty and Insurance

Apple’s One-Year Limited Warranty covers eligible manufacturing defects, but Australian customers may also have additional rights under Australian Consumer Law beyond that one-year period. Accidental damage such as drops and liquid exposure is generally not covered by Apple’s Limited Warranty, although AppleCare+ may provide accidental-damage coverage subject to applicable service fees. If your iPhone 16 hasn’t been dropped or exposed to liquid, it’s worth checking your Apple warranty or AppleCare+ status before paying for an independent repair. Third-party phone insurance policies vary — check your policy’s fine print, as most cover accidental damage but not manufacturing faults.

We are an independent repair shop, not an Apple Authorised Service Provider. For hardware-related flickering outside Apple’s warranty, we offer a free check and a same-day screen replacement using genuine Apple parts where available or high-quality aftermarket display options, depending on your preference and budget, with a 180-day warranty on the work.

iPhone 16 Screen Flickering – Frequently Asked Questions

The most common causes are Auto-Brightness or True Tone conflicting with the ambient light sensor, a recent iOS update, an outdated app, or pressure from a case or screen protector. Flickering that started after a drop or water exposure is more likely a hardware issue with the display or its connector.
Try restarting the phone, toggling Auto-Brightness off then on, temporarily turning off True Tone, updating to the latest iOS version, and removing your case and screen protector to rule out pressure on the display. Most software-related flickering clears with these steps.
Often, yes. Apple has released display-related fixes in past iOS point updates, and a small number of flickering reports on iOS 26 and iOS 27 have been linked to display bugs since patched or under investigation. Check Settings > General > Software Update first.
Flickering tied to brightness changes, a specific app, or a recent settings change is usually software. Constant flickering, coloured patches or lines, flicker that continues on the Lock Screen regardless of settings, or flickering that began after a drop or liquid exposure points to a hardware fault.
Apple’s one-year Limited Warranty covers manufacturing defects but not accidental damage. If your iPhone 16 is still within its first year and hasn’t been dropped or exposed to liquid, check your AppleCare or Apple warranty status before paying for an independent repair.
It depends on your policy. Most phone insurance covers accidental damage rather than manufacturing faults, so a flicker with no drop or liquid history may not be a valid insurance claim. Check your policy’s terms, or ask us for a written quote to submit if your insurer requires one.
