According to the latest rumor samsung is thinking about making the Galaxy S8 come with a pressure-sensitive display. Just like Apple's 3D Touch on iPhones.
The technology detects how hard you press on the screen, and this can be used by software to enable different functionality depending on the pressure level applied.
The rumor is coming from multiple "industry sources", as well as "a senior executive at Samsung's component division".
The first smartphones to employ pressure-sensitive displays were Huawei's Mate S and Apple's iPhone 6s and 6s Plus last year.
Interestingly, Samsung is a "key supplier" for Huawei's pressure-sensitive displays.
