Is Magnifier not working on your iPhone after iOS 17 update? Fix the problem with these easy tips!

With Magnifier, you can turn your iPhone or iPad into a magnifying glass to zoom in on and detect objects near you. If the Magnifier app is not working or the app has a black screen after iOS 17 update, it’s almost always a software issue, not a problem with the lenses or sensors.

Here’s what you can do to fix the problem.

5 Ways to Fix Magnifier Not Working on iPhone in iOS 17

Before you start to troubleshoot, if there’s something obstructing your iPhone camera and causing the black screen on Magnifier app, remove it and continue using the Magnifier as normal.

But barring that simple solution, here are five more ways to fix Magnifier not working on iPhone in iOS 17.

1. Close And Reopen The Magnifier App

It’s possible the Magnifier app, not your iPhone, is causing the problem. Apps can experience a number of malfunctions that may cause them to stop working. There’s a good chance the Magnifier app is not properly loaded up when launched. In that regard, you should try force quitting out of the Magnifier app and relaunching it.

If you have an iPhone SE (second generation) or newer, double-press the Home button to open the app switcher. Swipe up from the bottom edge to the center of the screen to open the app switcher on an iPhone XR and later.

Swipe Magnifier up and off the top of the screen to close it. We recommend closing your other apps too, as one of them may be causing the problem. Wait a few seconds before reopening Magnifier to see if it’s working again.

2. Restart Your iPhone

The next troubleshooting step to try if Magnifier is not working or showing black screen is to restart your iPhone. Performing a quick restart fixes a myriad of issues and could be all what you need to fix the Magnifier problem on your iPhone. After all, a reboot refreshes the iPhone’s memory and clears caches.

If your iPhone has a Home button, press and hold the power button until the “slide to power off” display shows up on your screen. If your iPhone doesn’t have Home button, simultaneously press and hold the power button and the Volume Down button instead. In either case, swipe the power icon from left to right to shut down your iPhone.

Press and hold the power button again once your iPhone has had time to fully shutdown.

3. Update Your iPhone

Some rare software bugs could also be making life difficult for Magnifier. Hence, be sure your iPhone is running the latest version of iOS. Just in case your iOS device hasn’t got the update for quite some, it wouldn’t be wrong to blame a bug for the whole mishap.

Start the Settings app on your iPhone and go to General > Software Update.
Let your iPhone check for the available update. After that, tap Download & Install or Install Now if an iOS update is available.

4. Delete and Reinstall Magnifier App

And when all else fails, and the Magnifier app is still not working on your iPhone, you may need to try deleting and reinstalling the app.

Touch and hold onto the Magnifier app icon > Remove App > Delete App > Delete.
Then, open the App Store > Find Magnifier and install it.
Next, launch Magnifier and check if your problem is solved.


If you have tried everything in this guide and Magnifier is still not working on your iPhone, then it may be an issue with your hardware. The only way to fix that is to contact Apple Support or take it to an authorized repair center to see what they can do

Before you turn your iPhone into a magnifying glass to zoom in on and detect objects near you, be sure to let us know the trick that has worked for you. As always, if I have missed out on any handy troubleshooting step, do not forget to remind me of that as well.
