Evo utisaka as xda:
Okay, here's the review with a full wipe:
Negatives
1) Multitasking is completely broken. (I tried to run 2/3 games at the same time but as soon as you switch back to the first game, it has closed). ALSO, switching between applications (when there are many) takes a long time!
2) Some parts of the ROM are not in English (despite English being selected as the main language). For example, connect your USB to your phone and the USB dialog is not in English. You may not find it annoying. I do.
3) Sometimes, notifications stay expanded even if you collapse them. I took a screenshot and was downloading apps at the same time. The notification for the screenshot kept expanding by itself even when I collapsed it. This behavior is mostly random (it's working correctly now...)
4) There is a Telenor app present by default (not really needed). Yeah, yeah. I know, it's a Swedish ROM.
5) The phone is heating up a lot when playing games
6) Overall, the ROM doesn't seem all that smooth. You'll definitely see it lagging a tiny bit here and there when a couple of applications are open. Proof enough that Samsung have ruined Project Butter in most places.
7) No multi-view support in this ROM.
8) The video player doesn't have its own brightness settings.
9) The Gallery is the same as ICS. No Note 2 gallery. Yeah, we probably won't get it.
10) The status bar is still grey (it doesn't bother me but I know most of you hate it)
11) The widgets' drawer still lags on its initial load (meh, doesn't bother me now).
Positives
1) The micro-lags and jitters in the games (present in the Polish JB version) are gone.
2) Wifi signal strength is stronger than ICS
3) Contacts takes half a second less than ICS to open (still kinda slow). Project Butter really shows here when you scroll down the list.
4) You can immediately scroll after opening a list (such as Contacts and Music Player).
5) Google Now works perfectly.
6) There's a new LED indicator setting for "Voice Recording" that wasn't present in ICS.
7) Menu opens up twice as fast as on ICS.
Well, that's my initial impression. Will get back with more once I find stuff. It seems better than the Polish version.
