Now that the iPhone 6 and 6 Plus is comfortably on the market, it is time to start the rumor mill on the iPhone "7."

According to ValueWalk, concept images of next year's iPhone are already starting to hit the Internet. Martin Hajek, a tech designer, developed his own aesthetic concept complete with some key features.

In a post on his website detailing his concept, Hajek said his design is based on a piece from Steven Tweedie, a tech blogger for Business Insider.

Hajek's design maximizes the iPhone's screen, spreading its display literally to every corner of the handset. The Touch ID fingerprint scanner/ home button is situated in its normal spot, but this time embedded into the display. Hajek put the flashlight, camera, Bluetooth and auto-lock buttons on either side with the iPhone dock resting just above.

This display could work, in theory, if Apple revamps its effort to coat their mobile devices in sapphire glass. With a maximized screen, cases for the handset could become more complicated, so the ultra-tough material would ease customers' minds.

Russian designer Grisha Serov focused on the side panels of the next iPhone, ValueWalk reported. Serov took the home button of the front of the handset entirely and put in the side in a thin Touch ID button. Gerov also redesigned the volume button, combining it with the mute button.

On the back of the iPhone, Gerov's design does not have the camera lens popping out.

Perhaps the most intriguing potential feature for the next iPhone could be a 3-D display with motion sense technology. Apple would not be the first company to add gesture recognition to their handset, but it would certainly be a welcome feature.

According to 9to5Mac, Apple was granted a patent for just that, thanks to its acquisition of PrimeSense. The website reported that Apple wants its 3-D experience to be completely glasses-free.
