El mismo no recomienda cambiar solo el cristal ya que va con el digitalizador:
"Its not looking good for glass only replacement. The gorilla glass is 0.6mm and is bonded with optical adhesive to the digitizer glass which is 0.3mm. The digitizer is bonded around the outside to the amoled which is also 0.3mm. With the glass so thin I think any attempt to remove the glass might crack the digitizer or lift it away from the display causing damage to the digitizer flex."
