Is it the time for me to switch to Android? iOS is riddled with spyware.

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)
