iPhone 6s/7 what version of iOS is preinstalled?

[tomolovic]

I would like to ask what version of iOS is preinstalled on new phones?

We bought new phones with my brother last week and we were surprised by the versions...


iPhone 6S 32GB - iOS 11.0.0
iPhone 7 32GB - iOS 10.3.3


It is normal? Thank you in advance

Yes, it's normal. I strongly advise you to downgrade your 6S to 10.3.3 while it's still possible. You don't have much time...

Why? My 6s runs better than ever on ios 11. Only downside is a bit higher battery usage.

I've heard about stuttering and lags on iOS11 with 6S. Mine is smooth as butter on 10.3.3

Not something I can recognize. Mine smoother on 11 than on 10. They seem to have fine tuned the animations. Anyway it is no longer possible to downgrade anyway: https://www.macrumors.com/2017/10/04/apple-stops-signing-ios-10-3-3/

Only on 6S is still possible:

Ok, odd. Wonder why 6s can but not other iPhones. Not even 6S plus..

Something to do with 3rd party screens not working on iOS 11 only on the 6S

Because 6S won't recognize touch gestures on some of the third party screen repairs under iOS11. This was already resolved in 11.0.3 and they will stop signing 10.3.3 any moment. If you decide to downgrade - do it now.

Great, thanks for quick answers. So I assume according quite late versions that iphone were just produced quite recently, is that correct?
