iOS 14 almost certainly won’t be unveiled before June, but information leaking out of Apple indicates this next version will offer very wide compatibility for current devices.
News about iPadOS 14 compatibility isn’t quite as good.
iOS 14 upgrades for everyone
This includes older models, including the iPhone 6S, iPhone 6S Plus, and iPhone SE. There will not be upgrades for handsets that didn’t get iOS 13, like the iPhone 6 series.
What’s coming to Apple’s handsets in this update is essentially a complete mystery. While numerous details about 2020 iPhone hardware lave leaked out, nothing about iOS 14 has slipped out of the company yet.
Some older iPads won’t get iPadOS 14
The same source also informed iPhoneSoft that two tablets that received iPadOS 13 won‘t make the move to its replacement. There reportedly will not be iPadOS 14 upgrades released for the iPad Air 2 or iPad mini 4.
These came out in 2014 and 2015, respectively, and run the older Apple A8 and A8X processors. Both were discontinued last spring.
Aside from these two, every iPad model that can run iPadOS 13 supposedly will be able to run iPadOS 14.
While any unconfirmed report should be looked at skeptically, this same source was able to accurately predict which iPhones and iPads would get iOS 13/iPadOS 13 upgrades months before the official announcement.
