serious? okay.. because on youtube many of the videos they remove it and apply their own screen protector..

you using clear screen or anti glare screen protector?
are you on a custom rom as well? AOSP based?
hmm i think i saw a review saying it wont void, but who wants the "SONY" logo to be taken off right.. not that we like to advertise, but having the logo makes it feels different while holding/using it, dont you think?
some say sony is trolling with the logo sticking onto their shatterproof screen guard.

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.
