[Galaxy S II General] diaperboy:
Review on the JB Leak ROM.

So, I was as excited as the next GS2 'fanboy' when the first leak for JB was pushed through by xda forum member izapp.

Hell, I was also one of those who would refresh his thread on xda every few minutes, eagerly awaiting its appearance (as I'm sure many of us were :p)

Once it was out, I was quick to flash it and so very pumped to get a somewhat official JB ROM going.

I tried it out for the next week to see how it would suffice to the oh so popular CM10, and here are my thoughts.

Stability

- Exceptionally stable. A definite 8/10, and I only give it an 8 because this is simply a leak, and the official OTA update will far surpass it.

- Project Butter is definitely evident in some form.

- Opening the App Tray is FLUID and flawless. Even with the phone on "Power Saving" mode.

ROM

Pros

- We were all very excited to see

Touchwiz Nature UX

on board.

- Brings it closer to the new set of Samsung devices.

- Almost all the "Motion" capabilities were available from the S3

- Improved stock Samsung Keyboard, neater design.

- Stock Keyboard also has Swipe functionality built in.

- Stock Camera app is able to pause while filming.

- 0 shutter lag implemented

- Able to long-press on notification toggle to jump to full settings (ex. long press wifi toggle, jumps to full wifi settings)

- Ability to change Font size (Compared to stock GB and ICS, where only font style could be altered)

- Able to change text message Font size using volume rocker (have to enable it in settings first)

- Can allow phone to constantly remind you of a message that has been left unattended. (check Message app settings to enable this feature)

Cons

- Some hate Touchwiz, some love it. I personally like the launcher.

- Some key "Motions" not available. "Swipe to Screenshot" for example. I also noticed "Smart Stay" to not work for me. (EDIT: The general say is that Smart Stay works, so I'm assuming that it was a fault on my part :) but glad it works)

- Keyboard is sometimes laggy, and is also missing some Prediction settings. (But that can always be changed through a 3rd party keyboard)

- Stock Samsung apps do not look as good as AOSP, especially the messaging app. (in my opinion)

- No addition of BURST shot mode (Hardware limitation [

])

- No ripple effect on lock screen. (without messing with dpi) (Option to add ripple effect 'as mod for odexed and deodexed LSJ rom on XDA' [

] )

- Notification toggles occupy a lot of space, leaving less room for notifications itself (Official firmware might add option to remove brightness bar [

])

Battery Life

I realise it is not completely fair to judge battery life on a leak, but might as well.

- Power Saving mode definitely is effective. And is not too laggy when its enabled.

- Battery life however is very disappointing. I was able to get 5 hours of battery life, with wifi enabled. Texting often, and an hour of phone calls.

- When left through the night (1am-8am) (with power saving enabled), wifi switched off, I would lose 15% on average.

Overall Thoughts.

In my opinion, it is a beyond satisfactory leak. It yields smooth and fluid transitions with the aid of Project Butter. It will definitely satisfy the thirst of those who love Samsung's android skin until the official firmware is out for update. However, i resorted back to CM10 after a week of stock 4.1.2 on the S2. I simply prefer the look and feel of AOSP based ROMs. The apps have a cleaner and more sophisticated feel but I also think that Samsung have done a great job in making Android their own, which many love. :)

Hope this helps anyone thinking about flashing the update. :)
