Screen Detection

I am new to image processing. I have been looking at some of the samples and other posts for trying to detect the mobile device screen region of an image taken of the device. The library has a lot of build-in methods but struggling to figure out the best approach. Here are links to a couple of images - one with the screen all white and another with it all green.

Looking for approaches to find the screen location, adjust for geometry knowing that the screen is rectangular and creating a new image of just the extracted screen region.

Thank you,

What did you try so far?

What about some color filtering, thresholding, blob counting, etc? Just few ideas ...
