It might interest you to know that the awaited iPhone 7 comes with some important physical changes. For once, the phone faces removal of the audio jack port. Hence, listening to music will require Bluetooth headphones or the like. Actually, Apple will make sure you will only use their own headphones. Nothing new here.
On the other hand, the new iPhone will likely grow 3 extra speakers and start seeing in stereo vision. This should be the most attractive feature of the new model since it will otherwise look and perform just like its predecessor, iPhone 6s. So far, iOS 10 will be released mid June and will also be featured in the new iPhone. It comes with some security changes and an improvement to the music app interface. All reasons to rave, of course.
Although stereo cameras are not new, Apple hopes to spearhead this feature into the mainstream market. That’s probably the reason why they didn’t hurry to improve on the iPhone 7 performance capabilities. However, they will get another shot in 2017 and probably double down on the sales.
