Z3 compact here – I use a Ringke Fusion case and a couple of thin tempered glass screen protectors – as I am thinking that the laminate effect might give more impact protection than a single, thicker one.
I had this one before but I screwed up putting it on :
but if you lay the glass on the screen in the correct position and then tape one side to the phone with masking tape, then fold it back to clean the screen with a cloth that is a bit ‘anti-static’, you can then peel the backing of the protector and let it fall onto the screen, for a much more successful result.
