The iPhone 6s and iPhone 6s Plus went on sale last week, but that has not stopped rumors about the iPhone 7 — due to be launched late next year — from making their way to the Internet.

The latest set of rumors originating from China for the iPhone 7 claim that Apple is testing a waterproof and dustproof design for it. The iPhone 6s and iPhone 6s Plus don’t feature any kind of IP certification, but they still managed to survive this underwater test that lasted for an hour.

Another posting on Weibo claims that Apple plans on moving away from the metallic frame that it has used on the iPhone 6 and iPhone 6s. The new material that Apple plans on using on the next-generation iPhone remains unknown for now, though the company has already developed the first prototype based on this new material.

Lastly, the rumor claims that the iPhone 7 will feature a completely flat LCD panel. The iPhone 6s and iPhone 6s Plus already feature a flat LCD panel, so it is likely that the rumor is pointing towards the curved glass protecting the display found on the existing iPhones.

Considering that the iPhone 7 is still a year away from being announced and is in early stages of development, it is entirely possible that the device will be completely different from what the rumors mention above.
