Thin film which adheres well but is also easily removable

The film is pretty thin, which is advantageous for touchscreen. The issues raised here difficulties in putting on the phone I can not understand. I have freed the display of grease and dust, have a film taken from the carrier, the "hole" for the speaker above and aligned with the upper edge and then I went to the credit card once from top to bottom, and the film sat bubbles on the Display - less than 2 minutes hats lasted.
