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)
This being displayed as "Unknown" is likely just a bug or an app you (very) recently uninstalled. And you probably opened the camera app by accidentally swiping right to left on the lock screen. Even just a slight swipe will launch the app so it's ready when you're done swiping.
And I'm not even sure what you're talking about regarding your QR code.
Android is not de facto superior to iOS, nor is the opposite the case.
If you're really that paranoid, even GrapheneOS on a Pixel shouldn't calm you down because it also requires proprietary firmware by Google (and possibly other vendors) to run on these proprietary devices. In this case my advice would be to stop using smartphones altogether and rely on open source computers (couple of RISC-V options out there I think) for your computing needs.
