    This is gorgeous. If I were in the market for an android phone I think this would be a no brainer for me.

    I'm not a smart phone owner, so pretty ignorant about the devices and their OS's. BUT...I'm wondering if a quad-core is even useful in a smart phone? Will the apps and OS take advantage of it?

    I like where the ear piece is located. I hold the phone at a 45' angle most of the time, half trying to keep my neural network from frying, half for comfort. It also allows the screen to fill more of the face, which it appears has been done here.

    Dont know about Quan core but I can tell you my Galaxy S3 is nice and fast!! wips Iphone 4s too :p

    BTW the non american S3 is also Quad core but not LTE we in canada have the dual core version :(

    From what I've read, Android phones take advantage of Quads the least, which I find funny because it is always a step ahead in regards to processing power. The OS isn't as optimized, but they are making strides in that. WP8 should be interesting because it was developed from the ground up for multi-core processors.
  8. Uh-oh.. rectangular with round edges.. another Apple's prey!! careful LG you've been warned :p

    No. And what'd you be surprised to know is that Android takes less potential advantage of multi-cores than WP8 or iOS do which is, ironically, detrimental when it comes to benchmarks.

    I say ironically because the very reason high-end Android phones are even seeked, is for the potential increase in performance. Performance that outside of raw numbers (numbers that, again, could be more if the OS was properly optimized) are mostly never even known by the self proclaimed smartphone enthusiasts.

    So that inevitably leaves us with people choosing the "fastest" of the fastest, simply <I>because</I>. Which is, again, ironic, as these very people often name call Apple fans "iSheep".

    So to answer your question no, not yet, but people don't care.

    Thanks, lawfer. So essentially - at least for now - bragging about 4 cores is basically nothing more than a sales pitch.

    There may be some use for a quad-core ARM smartphone. Like if you were to find a way to get Win8 RT installed on it. Could be a portable powerhouse.

    Windows Phone 8 is WinRT. Technically. It can support up to 64 cores.

    What it can support and what it can make use of are two different things.

    Except you don't seem to know the scaled down version of Windows NT 6.2 (ARM) that powers Windows RT supports only up to 64 cores, while the regular kernel found in Windows 8/Server 2012 supports up to 256.

    The reason why I said "technically" was because WP8 doesn't share all of the WinRT APIs found in Windows 8 and/or because it adds a few of its own.

    It is already given LG phones are good, their software support is another story...
    hmmm round corner and its a rectangle.... apple will sue LG definitely

    Can you quote your source for this, because Android is built on top of Linux. Which has been optimized to work on multi-core processors long before they became available on smartphones. In fact quad-core and android is a natural fit.

    Here is an article explaining some other benefits

    You are using android-zone as your source? That's like me using a press release from Apple to prove how revolutionary their phone is.

    Besides your source only vaguely goes over the benefits of multi-cores, not how Android wasn't optimized for them. If you look close their logic is quad-cores here being a new shiny motor, but what they don't realize is Android's suspension is not optimized to handle the horsepower.

    Essentially, with Android you do run multiple threads at the same time, but end up using CPU cycles in the background and can make the entire system less responsive and more unstable while it deals with the simultaneous commands. It's really not whether Android can't support multiple cores, obviously, but how efficient it is at managing them.

    Kernels like the Windows NT 6.2 (for ARM) were optimized--not simply made to "support"--for, theoretically, up to 64 cores. Not many, if any, ARM-based operating systems have that kind of support, not even iOS or Android. And it's funny too, because both Android and iOS are Unix-based; Apple has a closed ecosystem while Android is "open-source" (it really isn't), and yet the latter is the least optimized of the two.

    As for my source, here it is: http://www.theinquirer.net/inquirer/news/2182710/intel-claims-android-ready-multi-core-processors

    (Sorry not sure what happened to my previous post. Ignore it) [Moderator's note: previous messed up post deleted]

    lawfer, the source you quoted is an Intel engineer justifying why they are releasing a single core cpu when everyone else has gone multi-core, and then blaming the OS. So effectively another press release. It does not mention Windows or iOS either.

    If windows is so wel optimised for multi-cores, why are they only releasing dual-cores.

    Also, they are enough real-life benchmarks showing that some applications running on quad-cores, do run faster. So the user experience is improved. Which is why Android manufacturers will continue to bring out quad-core Androids.

    Sorry for the late response.

    You know what a press release is, right? Please find the actual definition of it, then compare it with what you just wrote.

    And why should my source mention other OSes? The source is talking about an Intel engineer who conducted multiple tests on multi-cores prototypes, and found out that Android's thread scheduler wasn't taking proper advantage of the processing power.

    Android uses Linux 2.6 for its low level management of resources. Linux 2.6 happens to use multi-level feedback queues as its scheduling algorithm. This favors I/O bound processes and short CPU burst processes (ideal for phones for responsiveness/interaction). This does however means that CPU intensive processes and low priority processes risk getting starved. This is tricky, as the scheduler needs to properly manage the processing power of the SoC to the respective running process; in Android, there are four:

    1.Active Process
    2.Visible Process
    3.Started Service Process
    4.Background Process
    5.Empty Process

    All that's being said by Intel is, that due to the lack of proper management of power to these processes, Android's multi-core performance is actually hindered, whether it is processes force-closing due to lack of resources or less than great battery life due to poor process managing.

    Due to Linux, Android can indeed support multi-cores, but Android has had certain modifications for ARM that don't include all the intricacies of a full-fledged Linux kernel. And this includes the thread scheduler.

    As for your Windows comment, what kind of processor are you currently running? Hell, don't answer that. Let me ask you, what kind of processor do you think gaming computers use? Dual-core? Quad? Octo? Well, Windows supports that and beyond, up to 256 cores. Windows NT for ARM doesn't support as many; "only" up to 64 cores.

    Guess what OS will power WP8? A modified version of Windows NT. Technically the same OS you're running on your desktop. So yes, for developers, it's kind of a big deal even if consumers like you can't see it. Did you know WP8 will also support DirectX?

    And why am I talking about WP8, you ask? Because it's underlying kernel has been around for more than 2 decades and it has been optimized for multi-cores from the beginning, unlike Android. (Android uses the Linux kernel, albeit a heavily modified one, please keep that in mind.)

    And who said quad-core phones run slower than dual-core ones? All I said Android is not taking advantage of the <I>potential</I> power. This is fact, sorry. It's also the same reason why the new LG quad-core that's coming out will still lag when compared to, say, the dual-core iPhone 4S. It's not about support, it's simply about optimization.
