One can screen crystal clear without any restrictions as previously seen. No impairment of color perception, or from side angles. I'd say it looks the same as before.
When sticking is noted that on the display surface of the mobile phone may not be less of the smallest particles of dust before applying the film! I have the display previously cleaned with a damp disposable lens cloth.
Then the phone must lie on a straight, solid surface such as a table, nothing blurred.
After that it is up to you to have a steady hand and a good eye, because the film adapts so well to the display that the edges finish exactly at the edges of the display.
I glued the film using my debit card.
Just slowly press with good pressure from the bottom up the slide so that any air bubbles no chance can be given.
My film now holds just six months and show no signs that they will be solved in the foreseeable future.
This product is worth recommending.
