Android Jelly Bean 4.3 update spotted on Galaxy S3 [Update: Fake!]

Reports of Android Jelly Bean 4.3 running on the Samsung Galaxy S3 have surfaced, apparently originating from Samsung's R&D department in India.

The screenshot above shows Android 4.3.0, and according to the KnowYourMobile website, the source of the leak says there is also another group of testers working on the update for the Samsung Galaxy Note 2 as well. The build number is shown as JDQ47.I9300XXUFMGQ which is also Samsung Galaxy S3 specific. 

It's not the first time we've seen 4.3 shown off, back in May a Nexus 4 was shown to be running it at a tech conference in Asia. Android 4.3 will most likely bring some features of the Samsung Galaxy S4 and HTC One Google Edition to all Android devices, including a new camera UI, updated fonts, Bluetooth 4 low-energy support, improved graphics capabilities and new notifications.

Android 4.3 Jelly Bean is expected to be launched in two days time on July 24th at a Google press event where the new Nexus 7 is also likely to be launched by Sundar Pichai, the recently appointed head of Android and Chrome.

Other rumors claim that although the S3 is still waiting for the update to 4.2.2, it's likely that it will be skipped in favor of 4.3 instead, but as usual this has yet to be confirmed.

Update: As pointed out in the comments, the Kernel build can only mean it's running 4.2.x version of Android. A much better explanation can be found in this comment thread.

This is undoubtedly fake, one cannot use a kernel compiled for Android 4.2 on 4.3 without adding the changes & recompiling it. This kernel was compiled the February 19 and at exactly 16:06:59 and the same used in the leaked 4.2.1 firmware.

Furthermore it has the same changelist as the leaked Feburary firmware (171637)

The kernel build itself was odd....

You're assuming that Android 4.3 necessitates the need for a newer kernel which isn't always the case.

Anyone can use an older 3.x kernel on Jelly Bean but the kernel requires compiling as there are technical changes involved when a new version of Android is released. They cannot use the same kernel specifically compiled for 4.2.1, it just won't work. If this was to be true when we'd certainly see a much newer build date.

Besides even the build number is totally fake, JDQXX denotes builds on the Android 4.2.x branch. Anything 4.3 will need to have the JWR number. The baseband version doesn't even match the kernel build date either. 'MGQ' indicates that it was compiled in July whereas the builds number states February,

Ah, ok - I stand corrected.

YES! Thank you. So ridiculous to see news sites jump on what was clearly a build.prop edit, and a poor one at that since they could have changed all those values.

Updated, for the record I have very little experience with Android, so SORRY!

So... You wrote a front page article, based on a single source? Come on!

The BBC often release breaking news which has only come in from Reuters, not all news agency journalists can be in the same place at the same time. Someone has to be the first to go, then the rest will follow...

is this the new strategy of google to fight fragmency? holding back the updates on the google devices until the competition caught up enough? this kinda sucks. im sure the update could hit the nexus devices for weeks.

android 4.3 with kernel 3.0.3. more fail samsung. even LG and Sony update their kernel to 3.4 on even the smaller phones

Same thing I noticed. Im on Android 4.2.2 and running kernel 3.0.6

BTW, although 3.4 is longterm, stable is 3.10 . 2.6.x is also longterm but noone runs that

Only newer Qualcomm & MediaTek devices run Kernel 3.4, all pre-Exynos 5 handset still use 3.0.31 since Samsung's kernel sources contain a lot of proprietary code which is not in sync with the main linux source repo. They don't usually add the incremental patches from LKA or CAF so the version number remains the same across all devices.

I'm running 2.6.35.13, but then my HTC phone is stuck on Gingerbread 2.3.4. Yeah, I've tried other ROMs, but they always have little nagging failures in something that pushes me back to a stock-based ROM. Future phone will be Nexus or similar, I'm not going to wait around for HTC or Samsung anymore.

I ment no new phone uses it

That isn't a stock device, is it?

Yes it's. India is carrier free world. So here everything is free/unlocked devices.

I see my failing to clarify, I was referring to the stock theme on the galaxy s3, (ui n'all)

To answer your Question, this is TouchWiz. The only Samsung smartphone that is stock is Galaxy Nexus and Galaxy S4 Google Play edition.

Lastly, it isn't a "theme". It is an operating System. TouchWiz is not a skin like some amateurs on this forum like to call it. It is a framework that is built on top of Stock Android. Most things are kept, some things are removed. Sorry for the rant.

Ok no probs, although I mostly failed to clarify what I meant, the reason why I started in my line of questioning was because I know my phone, and I've seen an international version of the s3 also, that colour scheme didn't look right to me, my s3, the international s3, the galaxy tab, the galaxy note 10.1, all have almost identical colour schemes when you go to the software information page, (like displayed on the above phone) (assuming the user hasn't changed it) (I like touchwiz, but I haven't tried a non touchwiz phone so cannot make a comparison.)

I'm sure it is the same software but carriers like putting their own color schemes / wallpapers.I know with the GSIII they have two versions, the international version and the North America version. Each had different specs.
