advice galaxy s6

[vex_dm]

I have broken glass on my galaxy s6 and lcd don't work. I don't know what grade of lcd to buy? B grade is cheaper. Is there any difference between this two? And if I buy A for example how can I know they didn't sell me b grade?

A grade is usually new B grade is usually used and will have small scuffs and scratches, or new screen but with manufacturing defects such as small scratches. 

if you are not knowledgeable in the repair of phone screens id suggest you take it to a local repair shop/Samsung service center the Samsung are not easy phones to repair compared to iPhones and a lot can go wrong if you are not experienced.
