[Xperia Z3 Compact General] QBerto:
u're in drugs dude xD, this is Sony official lollipop (also, is "battery seems better on stock THAN CM12" but well....)

On topic....

well... actually I'm impressed, is the first time I see a Sony update with no bugs at all

The integration of SonyUI with Material Design is almost perfect, nothing looks out of place like others OEMs's customizations (well,,, TouchWiz always look out of place imao xD). Performance is better that KK (and as a plus, AnTuTu gives me score of 46k vs 40-41k on KK, but benchmarks are... well u know), and never see any lag with tons of open apps, but I thinks is hard to make lag such a great phone since KK.

Is good have a multiuser support, apps2sd (but could be better), an estimated time for full charge; and I think the new notifications/quick settings bar is good, and actually all lollipop is... "cute" xD. Also, the camera is... maybe the same, but is a little faster (never had the pink thing before btw)

Now, there are some things... not bad, but could be better: first of all (and I think the only sony-related) Sony integrated Update Center in What's New, that sucks, but is not big deal, is a way to make us use their useless app.

The second I think just need to get used, and is about sound; if u see there's no "Sound" option in quick settings or turn off menu, so the only way to put the phone in silence is pressing volume up or down, and selecting Silent (no sounds at all), Priority (where u can choose what will sound, in settings>Sounds&Notifications>Interruptions u can configure) or Normal, problem is when u're playing music, because the volume menu is for media now, not call/notification sounds, and the three options will not appear (still u can set silence in Settings>Sounds&Notifications, but is not fast as it was on KK).

The third (that actually makes a lot of sense) is that if you activate an Accessibility Service (e.g. TalkBack) u can't set any Screen Lock (like patterno, PIN, etc.) more than Swipe... in my case this is bad, because Greenify needs and accessbility service to work.

As a fourth, I don't know why Location-Based Wi-Fi is gone, but the good part is that at least in KK for me didn't work as intended. A quick fifth is that the only way to activate/deactivate auto-brightness is activating Adaptive Brightness in Settings>Display, wich is a little more laborious than before.

The last one is with no-lollipop apps, where actually doesn't seem integrated (for example with a ugly blue bar on top), but with some time this will be solved (or I think)

Now.... maybe u read all that trying to get an opinion about battery life.... and the stupid dude that write all that doesn't talk about that! (what a douche! xD)

Actually, imao is just stupid talk about battery life with ONE day of use, but if u want something, I can say is a little better, because I go to work with 89% battery (~7:30am), and after viewing all settings, and lurking lollipop, installing some apps, playing as usual, giving an usual use (lol) get back to home with almost 25% (~10:00pm), the same on KK, but I'm sure I used more the phone...... but after all, is just ONE day...

Oh and I almost forgot,,, one weird thing was that when I conected NC-headphones and turn on radio, the radio just sound when the screen was off.... when I turn on screen, the radio shows like working, but can-t hear anything xD.... tomorrow will test again..

And that's all I can say until now... greetings dudes!!
