[Galaxy S III Android Development] traitor123:
A review by DeadSOL on the new 4.2.2 JB Leak:

Edit: Updated

Differences

:

Lock screen: You get the 4.2.2 lock screen with

widgets

(swipe left or right). Additionally, you can activate

Daydream

. You can also set your own lock-screen message. The

Music Player

now comes on the lock screen when playing music. See Settings below for more stuff in the lock screen settings.

Notifications: 4.2 notifications present when you press the icon in the notification drawer (taken from the S4). One finger expandable notifications also present.

Calculator: It gets a new icon and that's it!

Contacts: It has a cleaner S4-esque look. Scrolling is absolutely smooth.

Gallery: When you change the view mode, the background becomes white. It looks unfinished, ugly, and doesn't match anything.

Music Player: It gets a complete overhaul. Now it looks and feels like the one on the S4. It looks a lot better and gets additional features such as

Smart Volume

and

Voice Control

(which was included in S-Voice previously). Also, the Music Player now appears on the lock screen when playing music. There are new equalizer settings and the volume seems to be louder, too.

My Files: It gets new folder icons and new icons for Device Storage and SD Memory Card.

S-Memo: It gets a few additional options (such as linking a note to S-Planner and other insignificant things).

S-Voice: We get the updated S-Voice (taken from the S4).

App permissions: App permissions are cleaner; Jellybean 4.2 style!

Partitioning: Since this is Jellybean 4.2, your partitions will be changed. This is because of multi-user support for tablets (we get the same software).

Settings: The settings menu has been completely revamped and it looks like the tabbed settings menu in the Galaxy S4.

Lock Screen: You have the choice of two unlock effects;

Ripple

and

Light

. You can choose between a

personal message

and a

clock

. You can enable or disable

multiple widgets

.

Display: You now have

adaptive display

and professional photo display in Screen Mode.

Daydream

is included here.

Driving Mode: A new driving mode is under My Device in Settings.

Smart Screen: Smart Stay and Smart Rotation are included here.

Voice Control: It is now listed under settings.

Video drivers: Video drivers seem to have been updated. Epic Citadel gives an average FPS of 55.3 on the first try.

Samsung keyboard: You can change the keyboard to the floating Note 2 type keyboard.

RAM: Total RAM available is 828mb.

Things Not Included

:

Touchwiz update: Touchwiz did not get an update. It's the same old version.

Camera look and features: The camera app has not been updated to look like the Galaxy S4 one. Additionally, you don't get the extra modes that you get with the S4. Photosphere wasn't included in the S4 so we won't get it until somewhere near September (according to rumours).

Missing apps: S-Health, Smart Scroll, Smart Pause, Air View, S-Travel, S-Translator, Samsung Link, and Photo Reader.

Assisted Light Widget: The Assisted Light widget has been removed from this firmware!

Negatives/Unresolved Issues/Bugs

:

Fully bloated ROM (you can disable ALL the bloat, though) with an ugly bootanimation.

Multitasking with games is still broken. You can't run two or more medium/heavy games in the background. One of them eventually restarts (if not instantly). NOTE: This also happens with a single game running but I've used two as a quick example.

Contacts and Phone don't open instantaneously.

Widgets drawer still has the initial loading lag.

When recording a video, left and right audio is switched.

[*]Home button to prevent screen timeout still tied to S-Voice.

YES!!!! It's gone!

[*]During Pop-up Play, clear type text is turned off and you can see jagged edges everywhere.

[*]One finger expandable notifications are not present.

(Requires further testing to strike off the list) Recent Apps Tab still randomly forgets the most recently minimized application.

(Requires further testing to strike off the list) Shadow redraws on Touchwiz icons occurs when the phone is low on free RAM

(Requires further testing to strike off the list) Touchwiz can restart when the phone is low on free RAM

Recommended or not?

:

Optional. It's a leaked ROM so if you want to try it, you can. It will increase your flash counter so beware! If you're desperately in the need to flash it, I say go ahead! It looks fine but let's give it a few days before we see if it's stable or not (although I haven't experienced any crashes or errors yet).
