I recently bought a broken s6 edge for 100 And all the parts costs me 150,what i did i bought a broken glass screen original and i changed the glass with tools for 20 dollars If you want to do it its going to cost you around the 160 mark +tools its not even hard

There are a lot of places like replacebase

Allspares,and a lot other but usually the back glass comes with the adhesive on
