Problems while scanning WhatsApp QR code on my iPhone

Hi fatima0409,

Thanks for reaching out to Apple Support Communities.

It sounds like you're having an issue with scanning QR codes.

We're happy to assist.

We recommend checking out the steps in the section titled "How to scan a QR code with the Camera app" from the article here: Scan a QR code with your iPhone, iPad, or iPod touch - Apple Support

1. Open the Camera app from the Home Screen, Control Center, or Lock Screen.

2. Select the rear facing camera. Hold your device so that the QR code appears in the viewfinder in the Camera app. Your device recognizes the QR code and shows a notification.

3. Tap the notification to open the link associated with the QR code.

We're recommending the steps above because they directly address the issue you initially posted about: you're having difficulty scanning QR codes.

If the issue that you're experiencing only happens when you're attempting to scan QR codes associated with WhatsApp, then we recommend that you contact the app developer via the link below.

3. The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.
