I use it on my Nexus 5 as a daily driver. You're exaggerating. Tremendously. Bugs? FCs? Nope. At least be clear of your experience when responding to an inquiry. It's not fair otherwise.
well, not sure if tremendous, but having to change wifi settings every time i reboot the phone is annoying, it saves the password but not the static IP settings. I did a clean install two times just in case, and that issuekept happening, plus some apps detected no internet connection when wifi was on (lie Google Music Play). If i had an unlimited data plan i may have kept L, but that was a big issue for me. I guess it depends on each one.
It is a pretty decent build though, i can see many people keeping it since it looks awesome and is really responsive and snappy.
Possible Xperia Z3 Compact spec leak
Nothing too outlandish, basically a Z1 Compact with 4.4.2 and the Snapdragon 801 instead of the 800.
slighly bigger screen too.
Let's see how it looks, i'd pick one as a second phone and to use it when going to the beach if still waterproof
