Can i update ios 14 in i phone 6

Hi! That’s not possible, it’s been dropped and it can not receive any new updates. If you really want the latest update then I’d say it’s time to upgrade to at least the iPhone 8.

I’d recommend the XR or the 11 as it has face ID and you can get them relatively cheap.

Nope, the iPhone 6 stops at iOS 12.

The iPhone 6S can get to iOS 15

Your maximum iOS is 12.5.5. For a new iOS if required for certain apps then you must buy a newer device ... iPhone SE 3rd Gen are not expensive.

Can you guys put the 6 to iOS 15.4.1

Hi! iOS 14 is only available on the iPhone 6S and above, not on the normal 6 series.
