remove it and apply a new one on. to remove it is easy. first take the battery out and wet your hand. and apply some drops of soap water to the edge of the screenprotector and then use your finger nail scrabbing it up. when you got it out enough to peel then just spray some soap water to the area and start peeling slowly while applying more soap water on the trail to stop it from sticking back to the screen.

peel it off then apllying new one on. the best way to do this is to peel the screen protector off the paper underneath it and dip it into soap water in a steam bathroom.

why?
because steam stop dust from flying into the screen while applying.

clean the screen and apply the soapy screen protector. align it until it is right. use a squeechy or credit card or any card to swipe out the water. dip the card in the soapy water to prevent scratch.

get the micro fibre cloth to wipe the exceeding water. leave the device to dry or use fan/hair drier to dry it for faster result. but don't heat it up. just warm air would do.


good luck
