So from the Chinese text, there's a new pink colour but not quite rose gold. Did I read that right? Something about taking pictures while also recording movies?
But the most impressive thing is the accuracy (just a touch from a finger tip) and even faster Touch ID performance, up to 30% faster than the 6, which is about the same as the Galaxy S6 (where the Samsung is not as consistently accurate).
Here's the translation from me, I'm a native Chinese speaker.
Earlier Prototypes of iPhone 6s had a 16MP sensor as its rear camera before it was replaced with a 12MP sensor. As expected, there're no major differences in appearance when comparing the iPhone 6 and iPhone 6s. There will be a new color addition which is pink frame with white LCD (not sure about the back though). This combination seems odd though, looks like Apple is "inventing" something new again.
iPhone 6S internal testing codes are N66 and N71, the rear camera sensor is now capable in capturing 4K Videos and 240FPS slow motion videos. Users will be able to control ISO settings manually now. (This doesn't fit the following sentences though) That means than you will be able to take a video after taking a picture (wat?), but the video will be joined together. You will be looking at photo normally but the phone will show a video after holding it for a specific amount of time.
Force Touch is available in the iPhone 6S but personally I couldn't care enough about it as it's useless to me. The part where the iPhone 6s impressed me the most is the new TouchID sensor with its incredibly fast unlocking speed and it's accuracy. The phone can be unlocked in a split second at any angle. I'm currently using the Galaxy S6, there's not much speed difference in using the fingerprint sensor on the Galaxy S6 ad the iPhone 6. There's only a slight difference in accuracy when comparing the fingerprint sensor on the S6 and iPhone 6. iPhone 6 and Galaxy S6 was blown out of the water by the iPhone 6s. It only takes a slight touch to unlock it from the sleep mode to home screen. The whole process takes less than a second and is estimated to be 30% faster than the sensor on the iPhone 6.
As a conclusion for now, the front facing camera has a 5MP sensor, rear facing camera has a 12MP sensor, equipped with 2GB of RAM, base storage option is STILL 16GB, Pink as a new color option (No, there will be no Rose Gold option.), there's no visible difference (appearance) when compared to iPhone 6, still has a protruding camera. (He missed out the new Touch ID sensor with the Force Touch sensor) The rest is yet to be discovered.
The translation may not be perfect but I'm pretty sure it still can be understood,
