Prominent rumors around the iPhone 7 include an improved screen, no physical buttons, a thinner body and a waterproof frame. Rumors about the iPhone 7 are unsubstantiated, and it is hard to know for certain which ones may come true.
A popular rumor around the iPhone 7 is that the screen is receiving a makeover to become much more resistant to shocks and fall damage. A patent belonging to Apple was discovered that showed a mechanism that would spring out of the front of a phone if it was falling, preventing the screen from being harmed on the ground. This screen may also be the only way to interact with the new iPhone 7, as another rumor revolves around the physical Home button being removed, along with camera and volume buttons on the sides.
Apple has continued to work to make the iPhone line thinner with each version, and the iPhone 7 is rumored to be even thinner than the iPhone 6. The case of the iPhone 7 is also rumored to be changing, and it may be created from a different material than the aluminium that Apple has used for so long. This case may, in fact, turn out to be waterproof, according to rumors.
