Now comes the big BUT: I personally have with the use of the film in conjunction with my iPhone 4 the problem is that when the iPhone on a table is the touch screen not working. I must first example with the other hand touching the metal frame and already it works. In my opinion, the film somehow changed the capacity (which recognizes the touchscreen) between fingers and touch matrix. Or electrically insulated just too strong.
The Vikuiti CV8 I have no problems! Unfortunately, this is in my opinion not quite as crystal clear as this film, but still very good.
I try now the Vikuiti ADQC27 from!
