White and blue, blinking light on front facing camera

On my front facing camera on Snapchat it shows a blinking light and also a regular white flash, but I have seen inconsistencies on the way it blinks but then I noticed a repetitive rhythm of the flash flash every three seconds. The blue light does a blink then two blinks, then a blink then three blinks, then a blink then two blinks, then a blink and then three blinks but in the mirror you can’t see it looking at your phone you can’t see it but if you use another phone to see it it’s there there’s three circles on top of the iPhone I have a iPhone 13 and one of them blinks the blue the other one does the flash and then you have your regular camera Why is that I seen this before on different articles but a lot of them try to say something but they don’t say anything about the way they blink or the flash which I know is not normal and then there’s that fact of it didn’t happen when I first got the phone it started happening with the new updates And a lot of these updates our security whatever but every time we have one I think our phones get more destroyed and corrupted than before but I don’t understand the blinking and the flashing and how it can’t be seen with the naked eye and what’s with the repetitive blinking rhythms and you would think you would see it in the mirror if it’s showing the same device and in the mirror it’s still using a third camera to look at it but it’s only the device itself that it’s showing the blinking and the flashing ?
