Chosen Solution

I am unable to open my iphone 6s because there is something stuck in the hinge, need help.

There is no “hinge” in the iPhone 6S. At the top of the device, there are flexes that run from the screen to the logic board so you don’t want to be pulling with too much force otherwise you can damage them. The screen is also held in place with an adhesive so that may be holding the screen back. If you haven’t already done so, check out this guide for more details.
