Einleitung

Since HTC U11 released, it has won lots of welcome comments, especially for its Edge Sense application.

Why is it so popular? And what exactly Edge Sense is?

Edge Sense has opened a new form of HMI, which is an intuitive action that is easy and convenient to get without learning cost. It was said on the release conference that Edge Sense is an Eight Super-Thin Strain Gauge. But what we want to see is how it looks like and how it works.

We will have a Teardown of HTC U11 to solve this puzzle.

    • As we could see the pictures showing that each side of the frame has a module (which we did not see on other mobile devices). It has thin structure but strong and stable signal.

    • Based on the Teardown works above, we came to a conclusion, that is, Edge Sense is an "8 super-thin strain gauge” with 4 pairs of sensors on each module that separately installed on both sides of the U11 frame.

    • These strain gauges are to detect the force changing while pressing, then the signals transmitted to the CPU of mobile devices for processing, and forming a signal output.

    • It could recognize long press, short press and different level of pressure.

    • It is not by recognizing the contact of skin (or we can say not by recognizing the Capacitive sensing) while squeezing to activate this function, but by detecting the pressure of pressing to start it. Otherwise how can we initiate the Edge Sense functions underwater or when we are wearing gloves?

Hello,

do you know where we can find parts for repairs and replacement ?

Marco Mondragon - Antwort

about to do my 2nd screen replacement on one of these at my shop. if i have time today ill try and photo the process of lifting out the display as it is not documented here, or anywhere else that i can find :)

Joshua Sites - Antwort

Hey Joshua, was the screen replacement difficult? I've never worked on a phone before but I'm plenty savvy. The back replacement is super clear-cut and straightforward with all the videos on it… is the front basically the same? Thanks in advance!
