So as you may know, i'm an iPhone user and a hater of Google. Recenly, it has came to my attention that i am somehow being spied on, as this has been appearing lately every single day:
Now i did not open the camera at all, and somehow it's saying that's being used.
Not only that, but basically i had a qr code saved in my camera roll. Every time someone scans it, i get a notification. However, randomly at 12 am, somehow i got a notification saying that someone scanned it. The QR code was not shared anywhere or posted, and the phone was offline at that time too. Now i think that its probably the time to switch from iOS to android.
Why is android superior then iOS, why, and how is it safer then iOS and what phone should i buy? (no pixel tho)
Are you sure you've NEVER shared the qr code with anyone? If so, what is it actually for? Because a qr code's purpose is to be shared. If you've ever shared it before, people can have copies of it. I myself take a picture of a qr code and load it from my camera roll instead of directly opening the link from my camera, because I want to keep a copy of it.
Now if you truly haven't shared it to anyone, then it is either a bug with whatever app, website, or mechanism you generated the qr code from and it's alerting you; or it's an IOS bug; with the former the more likely. Like others have said, this is absolutely not normal behavior on a non-jailbroken iphone. And to Apple's credit, the iphone is pretty secure. This should be the order of steps before going nuclear:
Find out if the source of the issue is the app or mechanism the QR code is using to alert you. Check if it's a bug or it's actually a malicious/rogue app.
If that's all good, clean up your phone. Check which apps have access to your camera and microphone, and disable anything you don't need or trust. Delete apps if necessary.
If that still doesn't stop it, hard reset your phone.
