The iPhone 6s and the iPhone 6s Plus have a new Screen tech**logy called 3D Touch, allowing the devices to support new gestures that are based on pressure, as well as touch. 3D Touch works through capacitive sensors embedded in the backlight of the devices, measuring microscopic changes in the distance between the glass cover of the display and the backlight, combining signals from the Touch sensor and the accelerometer to respond to finger pressure.
Apple's design guidelines for iPhone cases say any Screen overlay must be electrically conductive, must **t exceed 0.3mm in thickness, and must **t introduce air gaps between the touchscreen.
There are several Apple-approved Screen Protectors that are available for purchase from the online Apple Store and through Apple's retail locations, including products from companies like Tech21, Belkin, and 3M. Because the iPhone 6s and the iPhone 6s Plus are similar in size to the iPhone 6 and 6 Plus, it's likely these Screen Protectors Will fit Apple's newest devices, but customers concerned about fit should wait for confirmation from the manufacturers.
