I might be wrong about the warranty    Please ignore about it. haha.

Using clear and shiny SP But it became fingerprint magnet. Mine still stock rom, anything about custom rom u better ask sifu Andrewtst 

Enough checking review here n there... he he. Just go and get one.... By the way, best sp i've used so far is nillkin n benks hsr. But becareful, nillkin got fake oso and avoid benks hr.

Good luck.

I am using Nilkin screen protector (RM15 bought here) on the exsting shatterproof screen protector. No problem at all.

I am pretty sure 99% user apply screen protector on top the shatter proof sheet. 100% no sensitivity issue and yes nilkin clear type screen protector is great. I am using it also.

Removed the shatter proof sheet do void the warranty. Unlocked bootloader also void and disabled BE2 engine in browsing photo and also DRM. Custom rom like CM or  AOKP required unlocked bootloader. If plan unlocked, remember backup your TA before doing so to have chances restore back in future and return back complete BE2 engine and DRM.  If you never backup TA and direct unlocked the bootloader,  they is no more return back forever.

I use custom rom but not those CM or AOKP, those is bored, I only use it when stock not smooth, in Xperia  Z I don't see need to switch over.

I put anti finger sp on top of original protective sheet. So far no issue on sensitivity , works like a charm..
