Actually using standard xperia z3 compact screen foil on Jolla leaves following impression:
1. only speaker cut out fits, there are 3 cut outs more that make no sense on jolla.
2. vertical size is near perfect, protects from top to bottom.
3. horizontal size is smaller than jolla, leaving 2mm unprotected on each side.
4. edges are rounded where jolla has corners
Same with tampered glass or does it actually fit better? picture would be welcome @youmeego!
