The video tutorial was followed and the placement was done carefully a few minutes ago. Bubbles are not visible and, while the top and bottom parts have acceptable gaps, there are corresponding 1.5mm and 1mm gaps on the left and right sides from the edge of the screen.

The phone has a book case and I was looking for something to protect the screen in case it falls when the case is not closed.

The touch has not been affected at all, compared to the original membrane that was on the phone when I received it new. There is no special hole for the selfie cam.

I will come back in the future with further impressions.

***UPDATE 25/2/23***
It starts to peel off around the edges. The gap that has been left around seems to start bothering during movements from the edges of the screen.
I would not recommend it.
