This is where things can get a bit confusing. Not all aftermarkets or premiums are the same. There are many diffrent grades of aftermarkets and we use the highest quality we can find. There are a few diffrent variations of premiums ours use original lcd, flex cables, digitizer, backlight, 3D touch and glass. Premiums have a thicker glass and better hardness, do to the thickness of a aftermarket lcd the glass has to be thinner compared to a premium. We also install factory seals on LCD assembly per model. Below you can see diffrence's in better detail between the two we carry at this time.
