If you can’t justify upgrading to a OnePlus 7 or OnePlus 7 Pro you won’t necessarily have to miss out on all their new features, as OnePlus has revealed that a large number of them are coming to the OnePlus 6T, OnePlus 6, OnePlus 5T and OnePlus 5.

All of these phones are set to get Zen Mode – a feature which stops you using the phone for anything other than phone calls and photos for 20 minutes. They’re also all going to get Screen Recorder, so you can capture whatever’s happening on your phone’s screen.
