no you peel one layer off to reveal the side you put on the phone

you then put the protector on the phone

when on the phone you simply peel of the 3rd layer

so it leaves the middle layer on the phone

i used to use vikuti screen protectors at 10pound a pop from a seller in germany , very good quality and excellent service

however i tryed a few cheaper alternatives and these 3 layer ones are pretty much the same quality as the martin fields and vikuit screen protectors that cost approx 10pound a go

you got 3x screen protectors and a cleaning cloth so not bad price and they are quite thick quality and dont scratch easily like cheaper ones and also are easy to put on due to the tickness of them ie they dont shrivel up in your hand when you peel them off they remain flast and easy to put on and are one of the easies ive found to get bubble free application

worth a shot at that price :-)

i dont know my way round linux that well but i can defo help in the depot :-)
