The iPhone 6 has started in many rumors recently, and a new concept video now shows what the next Apple flagship smartphone could look like.

For all intents and purposes, the iPhone 6 is still a complete mystery. All that is "known" so far about the smartphone is based purely on rumors, predictions and speculation, and nothing will be certain until Apple actually makes an official announcement regarding its next-generation flagship smartphone.

While various reports so far have tried to paint a picture of what to expect from the iPhone 6, one man decided to make a video envisioning some of the smartphone's potential specifications. Rumors so far have mentioned two iPhone 6 models, one with a 4.7-inch screen and the other with a massive 5.7-inch display. The smartphone is also rumored to boast a quad-core 64-bit Apple A8 processor clocked at 2.5GHz, Touch ID, high-end front and rear cameras, a Sapphire glass panel, and more.

The video below does not depict the actual iPhone 6, nor a prototype that is currently in the works. It simply shows a concept for the next-generation iPhone in a bid to give us a glimpse into the smartphone's potential. This new video comes from ConceptsiPhone. Amine Kaddari is behind the concept, envisioning an iPhone 6 with a liquid metal casing and a high-end OIS camera.

In Kaddari's concept, the iPhone 6 sports slightly modified side buttons. The video also shows the audio jack that was relocated at the bottom of the handset instead of the top is now again placed at the top. The concept also envisions the smartphone with a larger 4.8-inch display.

As previously mentioned, this is just a concept aiming to show some of the possibilities of the much-rumored iPhone 6. While it's not a real product, the smartphone depicted here looks beautiful, sleek, and elegant, and many iPhone fans would definitely appreciate a larger display and a top-notch camera with optical image stabilization (OIS).

Apple's next-generation iPhone will most likely feature notable improvements over its predecessor, but it's all pure speculation at this point and the smartphone is not expected to debut anytime soon. The company usually releases new iPhones in September, and that's when we'll likely see the official iPhone 6. In the meantime, check out the video below and let us know what you think.
