S6 Edge G925F Front Glass replacement

[t-shock]

Hello guys!
I need your help. I own a S6 Edge but unfortunately the front glass has some scratches that they can be seen when the phone is open. I found at ebay that the front glass costs only 20 usd but I can't find any guide that shows if the glass can be changed. Have you try it? Will I have a success or I should gain some money to buy the whole screen?


Thanks in advance
