How to take off and replace the polarisor for s7 edge/ como quitar el polarizado para s7 edge 

No need to remove the polarized..you can install the glass with digitizer included and polarized and quality picture dont be affected, lcd still looks great with 2 polarized, due that take off polarized is to risk also some with spots remains and thay are impossible to clean it

hello I found your technique super well explain, can you advise me or I could buy LCD Foil for Samsung Galaxy S7 Edge Touch Screen as you use in your explanation because I bought at ebay LCD Foil for Samsung Galaxy S7 Edge Touch Screen Display but there is no sercuit print on LCD Foil

The screen is flexiply?

I can testify this cause I try many times in many s7 edges screens
