Applications
The next thing is a bit of enumeration of the skinned or custom applications that come bundled with SGS2 as part of TouchWiz 4.0. I’ve taken some screenshots of the default application bundle and some of the apps and tossed them into a gallery, and for the most part there isn’t much to talk about in detail.
Contacts takes you into samsung’s dialer application which thankfully is smart dial enabled, just like HTC’s.
Among the extras are a voice recorder, task manager, FM radio app, and of course Kies air. Voice recorder gets the job done and is pretty basic, as it should be. The TouchWiz task manager also is snappy and has some nice - kill everything - buttons to free up all RAM. The FM radio app supports multiple regions, RDS, and auto search. It has a nifty analog-feeling manual tuner too.
There’s also a video editing and photo editing application bundled. Photo editor lets you make some basic changes like crop, saturation, and some filters. It’s actually pretty decent.
Video editor does what you’d expect and seems to be a rather basic facsimile of iMovie for iOS, complete with a few themes and basic editing. The interface does a surprisingly good job at letting you trim and combine video clips, complete with transitions, and also stills. The live preview is a bit low framerate, which seems surprising to me, though my source material was 1080p video captured on the camera. Export is limited to 720p and does take a while.
Storage
Our SGS2 was the 16 GB unit, which came partitioned as follows:
Filesystem Size Used Free Blksize /dev 418M 76K 418M 4096 /mnt/asec 418M 0K 418M 4096 /mnt/obb 418M 0K 418M 4096 /mnt/usb 418M 0K 418M 4096 /app-cache 7M 4M 2M 4096 /system 503M 456M 47M 4096 /cache 98M 4M 94M 4096 /efs 19M 8M 11M 4096 /data 1G 402M 1G 4096 /mnt/sdcard 11G 1G 10G 32768 /mnt/sdcard/external_sd 7G 977M 6G 32768
What’s a bit curious to me is that it’s very well known that SGS2 has 2 GB of internal storage, however the /data partition above clearly shows only 1 GB. Apparently this is a known rounding error with the version of df in the firmware we’re running, and newer leaked 2.3.4 images show 2 GB for data appropriately.
Either way, having 2 GB is more than enough for application storage and shouldn’t result in anyone running out of space - this isn’t the 150 MB or so that early Android 2.x devices offered. Of course you can also add a microSD card for additional external storage and move apps to it, like I’ve done above as shown in the sdcard/external_sd mount. What’s really good, however, is that RFS is gone right out of the box, and in its place is EXT4:
/dev/block/mmcblk0p9 /system ext4 ro,relatime,barrier=1,data=ordered 0 0 /dev/block/mmcblk0p7 /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0 /dev/block/mmcblk0p1 /efs ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0 nil /sys/kernel/debug debugfs rw,relatime 0 0 /dev/block/mmcblk0p10 /data ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard 0 0 /dev/block/mmcblk0p4 /mnt/.lfs j4fs rw,relatime 0 0
The result is none of the filesystem lag that plagued the original SGS, looks like Samsung has learned its lesson here.
Software Conclusions
There are a bunch of other small things part of TouchWiz 4, including the ability to change the system font (which is becoming a pretty common feature) and motion-based gestures in some parts. Probably the most subtle extra I’m grateful for is screenshot functionality - screenshots can be taken by holding home and pressing power quickly.
For the most part, the experience is pretty pleasant and Samsung does make some welcome additions that improve browser and UI smoothness in Android 2.3 that likely won’t be part of mainline until Ice Cream Sandwich.

Thanks alot, going to do that today, however if you read my post above im not sure its an individual app causing it. Maybe i should root so i can wipe the battery stats and recalibrate, besides that im also going to purchase the offical extended battery from samsung, i dont mind losing slight slimness:)ph00ny - Monday, September 12, 2011 - link
I didn't even bother with rooting for a month or two until i wanted to try out chainfire plugins. Even in stock form, battery life was great. certainly better than my captivate.One thing to understand about SAMOLED screen is that it uses 0 power on black pixel and more power on white pixels. So maybe try out a darker themed wall paper and also check to see if you have widgets that have tendency to use up more juice than an alternative
Also for an example, samsung's stock music app uses roughly half of Google's music app power consumption. It gets worse with spotify (offline mode of course)

The trick is to adjust the power saving features to suit and make sure very little is going on in the back ground. I only run GPS if I need too and the WiFi gets turned off when i'm out and about, unless I know i'm in a WiFi zone and want to browse the www.I get at least a days use out of my SGS2.

Note:"When idle, processor goes back to 200 MHz"
Idle - screen on or an using a wakelock to keep the device on its the case.
Otherwise the whole CPU is turned literally OFF − everything frozen in RAM.
And in this situation, the baseband, Wi-fi chip or an external timer will wake up the CPU and restore Linux kernel in a working state when needed, like if you received a new mail, or a phone call.
I precise that because most people believe the CPU stays ON all the time but it's the opposite, with standard usage, the CPU is ON only a fraction of the day.

Brian, I don't think it's fair to compare the "tablet" version of A5 with the "smartphone" version of the Exynos and all the other chips. Even Nvidia's Tegra 2 has either 50% or 100% higher clock frequency for its GPU in the tablets, compared to the one in smartphones.It's very likely that all tablet chips are more powerful than the smartphones ones, and for all we know the iPhone 5 GPU will only one 1 GPU core instead of 2 like in the iPad 2, or they'll be clocked at a lower frequency.
I know you'll review the iPhone 5, too, but I think you're setting a too low expectation for the Exynos and the others compared to the "A5 chip". You know what I mean? You should've at least thrown a Xoom or a Transformer in there to see how it fairs against the Tegra 2 phones.
I hope at least you'll correct this in future reviews. Great review otherwise, though.

An iPad 2 can run sun spider 0.9 with 1980 score (4.3.5)If the Exynos is superior on every aspect of A5, the result is difficult for me to understand.

Just as I mentioned above, it's not fair to compare the tablet versions with the phone versions of the chips. All the latest smartphones get around 4000 in the Sun Spider test, but all tablets get around 2000 in that test, so even on the CPU side, it's still not a fair comparison.Mike1111 - Sunday, September 11, 2011 - link
Great review!But why are you so late with the review of the INTERNATIONAL version? I mean I would get it if you decided to wait for the US versions, but waiting almost 4 1/2 months and then publish a review of the international version only a week before the US versions get released? Seems strange to me...

Brian said in the other reviews comment sections that he was waiting to get ahold of a review unit. I did offer mine if he was nearby but he's nearly on the west coast and i live in the opposite side of the countryshamalh108 - Sunday, September 11, 2011 - link
Another pity is that even games from gameloft which are supposed to be adapted to the SGS2 cause significant heating of the phone.. for example the Asphalt 6 available for free in Samsung Apps .. it would be great if more games were coded to make better use of the SGS2 gpu ...
