Camera not working for QR Scanner and UPI apps after iOS 18.4 update on iPhone 16 Pro Max in India

Can Apple at least acknowledge this. It’s so inconvenient to not be able to make payments. Happening to me across UPI apps. Deleting and reinstalling doesn’t work. Neither does revoking and reviving camera permissions.

I am facing the same issue.

I’m using an iPhone 16 Pro Max and have updated to the latest iOS version (18.5). However, I’m still facing an issue where the QR scanner goes black in apps like PhonePe, Google Pay, Paytm, etc. The only temporary fix is restarting the phone, which is inconvenient and frustrating, especially when I need to make quick payments. Please look into this and provide a resolution as soon as possible. It’s causing a lot of discomfort in daily usage.

Struggling with same issue

Hey everyone,

I have a fix that worked for me. Not sure how long it’ll actually work for as I just did it 5 mins ago.

Settings > Camera > Scan QR Codes > deselect so that it is turned off > Resart iPhone (click volume up, click volume down, hold power button until black screen)

Issue resolved on iOS 18.4.1 after resetting all settings. Inconvenient but scanning is working.

I too faced this issue. Disabling the “scan QR code” (Settings > Camera > Scan QR codes) , restarting the phone and re-enabling it again worked for me.

I too had same issue , Apple support suggested to do reset all settings and this resolved in iOS 18.4 however it resurfaced again in 18.4.1 post update.

Same problem I am also facing

For me it's Walmart payment app and Safeway "UPC scanner" functionality. The actual camera for taking photos on my phone works great. It's not tied to permissions, etc. Only temporary fix is to reboot my phone. Not super convenient when I'm in line and people are waiting on me...

The camera in iPhone 16 models focus differently, not as close. The apps from Walmart, Safeway and other merchants need to ge updated. Please contact the app developers or the support teams at the businesses and alert them to the situation and request they update their app.

If you’re not in India, not using UPI, and not using an iPhone 16 Pro, why would you post in so specific a thread?
