The Samsung Galaxy Alpha and its 20nm Exynos 5430 SoC

Finally the rumored Samsung Galaxy Alpha is available for sale. The Galaxy Alpha is the first Samsung metal phone which features a 4.7inch 720p super AMOLED display, 12 megapixel camera, 2K video recording and 2GB RAM. Nowadays smartphones come with a 3000mAh to 2500mAh battery but this phone has only 1860mAh battery. Yes it’s a pretty small battery compared to the midrange specs it has, but Samsung claims it doesn’t need a bigger battery because it’s powered by their latest SoC called Exynos 5430.

The Exynos 5430 is the first Samsung 20nm SoC and Samsung claims it’s 25% more power efficient than its predecessor

Samsung Exynos 5430 is a big.LITTLE octa core processor which is manufactured under 20nm technology which means it has four big Cortex A15 cores clocked at 1.8GHz and four small Cortex A7 cores clocked at 1.3GHz. The Exynos 5430 is the first Samsung 20nm SoC and Samsung claims it’s 25% more power efficient than its predecessor Exynos 5420 which was manufactured under 28nm. Anandtech mentioned the use of the 20nm process a “significant leap forward” compared to the previous generation.

Samsung Exynos

Exynos 5430 has a Mali-T628 MP6 (six GPU cores) which is the same GPU Exynos 5420 (at 533MHz) had but now it’s clocked at 600MHz. This SoC has a dedicated H.265 hardware decoder and a dedicated Cortex A5 core to handle audio and voice recognition tasks. Samsung Galaxy Alpha smartphone is still new so neither battery benchmarks nor battery reviews are out there yet.  When they are available we can determine exactly how this new processor works with less power.

Samsung Galaxy Gear Smart Watch: Will it Sell?

Smart watches have been lingering around for some time without having a big take up. However seems like this scenario is about to change with some big industry players making their move on this market. Samsung introduced their offering the Samsung Galaxy Gear early this month and is set to be released in the coming week.

So lets see what the Galaxy Gear has to offer.

Processor and Display

With 800MHz processor and 512MB RAM, the Galaxy gear has processing power equal to a low end smart phone. The Screen is a 1.6 inch super AMOLED display with 320×320 resolutions.

Camera

The 1.9 megapixel camera is placed on the strap of the watch, with auto or macro focus and ability to shoot 10 seconds of video (upto 720p quality)

Interface

The interface actually looks nice with the bright colours and large icons. Navigation from the home screen to apps is done through horizontal swiping. Once you reach the end you come back to the home screen.

Battery life and Charging

As per Samsung, the battery would last you for a day. As we are not used to charging watches, frequently charging the Galaxy Gear would be an additional task and quite cumbersome. Also unfortunately you need a special dock to charge it, and the standard micro USB charger would do you no good.

Samsung Galaxy Gear

What can you do with it?

Smart watches will mainly act as an aid to the smart phone, and would have little functionality on its own. The Samsung Galaxy Gear follows the same trend. Here are some of the tasks you can do with it. More would be possible according to the availability of compatible apps

–          Answer and make Calls

–          Check notifications on your phone

–          Record Voice Memos

–          Take Images and videos

–          Auto lock when your phone reaches a certain distance away from the phone

–          Find your device

–          Control your music

–          Fitness tracking

 

Compatibility

Currently only with Galaxy Note 3

 

Will it sell?

We believe that for people to widely use a smart watch a) It should be reasonably priced b) It should have battery life for atleast a couple of days c) It should provide functionality that makes the experience of your smart phone better.

At a price point of $300 dollars this smart watch would cost you more than a Nexus 4 phone, and also with its poor battery life the Samsung Galaxy Gear definitely falls short on the first 2 of the above factors and since it only works(at the moment) with the Galaxy Note 3, it unlikely to be a hit. And hopefully the next version will be much more improved.

Samsung Galaxy S4 – Champion yet again?

Last year Samsung Galaxy S3, the leader in Android based mobile phones sold a whopping 30[1] million plus devices in 2012 alone. This year, the Galaxy S4 is off to a good start with 10[2] million units sold in less than a month after their launch. With the Galaxy S4, Samsung has introduced a whole bag of new features, while some of them may not be all that practical they definitely are some cool stuff to show off to your buddies.

The Galaxy S4 comes in two main flavours:

–          Octa-core variant (I9500)

–          Quad-core variant (I9505)

Before you get ahead of yourself, YES the Octa-core variant comes with two Quad-core processors, but NO they do not work simultaneously. Instead, the Exynos Octa-core processer packs two quad-core set ups being 1.8GHz and 1.2GHz respectively. Whereas the Quad-core variant is armed with the Qualcomm Snapdragon 600 1.9GHz processor. Apart from the processor, not much is different except the fact that the Quad-core variant comes with 4G LTE and the Octa-core sadly with 3G only.

Here’s a look at the key specs for the Galaxy S4 (both I1900 and I1905)

Galaxy S4

DESIGN

The Samsung Galaxy S4 may be one of the most anticipated phones of the year, but the design fails to surprise. Owners of the Galaxy S3 will see little difference on the look and feel of the Galaxy S4. Don’t be disheartened, the S4 is a looker but subsides when compared to Sony’s flagship Xperia Z and HTC’s One X, where the Galaxy S4 has a hyper glazed plastic finish. However, on the upper hand, the back panel of the phone can be accessed allowing users to change the battery if required – which is a No-No for both Sony’s and HTC’s flagships’.

The Galaxy S4 does bring slight changes on the outer bezel of the phone making it look sleeker adding to the only 7.9mm thickness of the device. The premium feel is lacking on this handheld even though Samsung have an aluminum-like finish covering the side of the phone. Samsung however have done a fantastic job in maintaining the height and width of the S3 albeit the larger screen. The build of the phone is quite good as well and feels sturdy and solid in the hand.

DISPLAY

Once the screen turns on, all subdues of the design are soon forgotten. The Samsung Galaxy S4 has an eye-popping display supported with the Super AMOLED screen and offers image quality that is par to none other. Both the high contrast and super colour saturation combine to provide the user with superb viewing pleasure. Some users aren’t great fans of the bright and toned look, and Samsung offers such users the ability to change the bright saturated look to a more natural display of colours. Additionally, S4 users will have nothing to complain about when viewing the phone in broad daylight and the viewing angles are great as well.

OS & USER INTERFACE

The Samsung Galaxy S4 comes with the latest release of the Google mobile platform i.e. Android 4.2.2 Jelly Bean, and is loaded with Samsung’s Touch Wiz 4.0. While some users may prefer the vanilla user interface by Android, the Touch Wiz update does bring some advantages. For instance, the lock screen that supports minimal functions on Jelly Bean; Samsung has gone all the way to introduce multiple panes with support for many widgets such as Email, Google Now, Messaging, Music Player, etc. The Lock Screen on the S4 can be thoroughly customized to one’s taste with background images, personal messages or clock with a desired colour and font.

The notification bar contains five customizable toggles that allow users to quickly enable or disable the feature, and users may slide across to view other toggles as well. Or user may simply tap the newly added button that lists out the total of 21 toggles.

The notification bar also displays the brightness control slider along with the general notifications that come with Android. 

Home Screen

The home screen hasn’t changed much from the predecessor, and you can pinch zoom to get the overlay of all home screens with a maximum of 7 separate screens.

One interesting feature is when you drag out apps and widgets to the home screen, you would see below a small layout of all your home screens with existing widgets and apps and gives you an indication of how much space is available on the home screen. Once added, the widgets can be resized and moved across the home screens with ease.

Camera

The Samsung Galaxy S4 sports a picture-crisp 13.1 megapixel camera and the picture quality is fantastic, but is it fantastic all round? And the answer is yes, it is! Pictures taken from the S4 during the day are quite amazing. They are crisp and full of colour, and with amazing detailing as well spanned across 4128 x 3096 pixels.

The S4 brings its users a vast set of options and modes. Here are the modes the S4 has in store for you:

–          Auto Mode

–          Panorama

–          Sports

–          Night

While the above are seen on most smart phones, here are some of the more creative modes:

Sound & Shot

Sound & Shot does exactly what the name suggests; you can record sounds while taking the photo. Even though, a practical use for this would be hard to find it is a unique feature none the less.

Drama

The Drama mode is loads of fun! If you have a planned action sequence you would like to take, you can use this mode to take a series of still images combining the shots of the animated subject against a steady background.

Galaxy S4 Drama mode

Animated Photo

Simply lets you take a series of images which will be combined to give you a nice little animation.

Rich Tone (HDR)

In this mode when capturing a photo, a series of images are taken at various exposure levels and merged to give a rich saturated result.

Galaxy S4 Drama

Eraser

This intuitive mode works by capturing a series of images and removing moving objects from the final image.

The S4 also allows you to set further options such as ISO, White Balance, Exposure Value, Face Detection, Anti Shake, etc.

Video

Video recording with the S4 isn’t the phones strongest suite, but there’s nothing to complain either. The S4 supports 1080p@30fps.


The Galaxy S Evolution – Infographic

It all started with Samsung launching the Samsung Galaxy S android smartphone in 2010, which had decent sales. They improved on it with the Samsung Galaxy S2 and had even more success with the Galaxy S3. Now with the release of the Samsung Galaxy S4, will the Galaxy S series become the most popular smartphone series in the world? I guess we will have to wait and see. Meanwhile, take a look at the below infographic on the evolution of the Galaxy S series.

Samsung Galaxy S Evolution

Samsung Galaxy S4, the most powerful smart phone in the world?

A couple of days ago in New York, Samsung unveiled its new flagship Android device, the much speculated Galaxy S4 (i9500). One year ago we saw the predecessor of this S4 the ever so successful Galaxy S3. When moving on from the Galaxy S2, the Galaxy S3 had a proprietary elegant design with poly carbonate exterior.  Samsung made the change in design due to Apple’s law-suits and other comparative reasons.  Due to the success in the S3 design,  Samsung  kept the same look in the S4 as well with some minor changes.

So lets kick off with the design and size in detail. The predecessor Galaxy S3 had a 4.8inch 720P display, with phone dimensions of 136mm, 70.6mm and 8.6mm. The new Galaxy S4 has a 5inch 1080P display, with phone dimensions of 136mm, 69.8mm and 7.9mm. So basically we have a phone similar to the  S3 design, with less thickness and 0.2 inch more screen area thanks to edge to edge screen technology. The Galaxy series generally have super displays and Galaxy S4 is no exception. It has a 1080P (441ppi) display which is powered by Samsung’s Super AMOLED HD display technology and it’s protected by Corning Gorilla Glass 3.

Power wise, the Samsung Galaxy S4 is the world’s most powerful smartphone currently available. The reason for that are its power packed internal components. This new phone is powered by a Samsung Exynos 5410 octa core processor. Yes! it has 8 cores in total, inside the Exynos 5410 exists 4+4 cores, 4 ARM Cortex A7 CPUs at 1.2GHz and 4 ARM Cortex A15 CPUs at 1.6GHz, when you are doing simple tasks like web browsing, reading, etc etc Exynos 5410 will use the low power A7 cores but if you start a heavy duty task like gaming the Exynos’s A15 cores will kick in. This technology which is called big.LITTLE makes the SoC more powerful and at the same time makes the phone  more power efficient.

You might remember the original Galaxy S’s GPU the PowerVR 540 single GPU. It was the most powerful GPU at that time period but Samsung went ahead with the Mali-400 graphic solutions for their S2 and S3, The S2 had a Mali-400 dual GPU and S3 had a Mali-400 quad GPU but those are not powerful enough for the  GPU hungry games. So Samsung decided to go back to PowerVR solutions again with the S4, having a PowerVR 544 triple GPU which is running at 533MHz. According to anandtech  this GPU roughly can produce 51GFLOPS of GPU power, which means you can except iPhone 5 like GPU power.

Samsung Galaxy S3 had an 8mega pixel camera and it took some amazing pictures. This new Galaxy S4 has a 13mega pixel camera and it has more exciting features than the S3. The new camera interface has more scene selections like Eraser, Cinema photo, Drama shot and Sound and Shot. In Eraser mode you can erase the unwanted background area and in the Cinema photo mode you got some exciting freeze features while you record a video. Now you can enable both cameras at the same time to take a picture, so you will not be left out in the group picture. By the way both cameras support 1080P video recording.

Samsung Galaxy S4

As you know, Samsung heavily customizes the Android OS through their TouchWiz UI. This new Galaxy S4 runs the Android 4.2.2 with the latest features built-in. This new OS includes Air View, Samsung Smart Pause, Samsung WatchON, Optical Reader, Group Play, ChatON dual video call, S Translator, S Health and more. Air view lets you control the mobile phone with gestures above the screen, while smart pause will hold the video your playing if you look away from the screen. Lot of nifty features but it is unlikely that they will be used heavily in day to day activities.

Looking at the Galaxy S4, it is powerful piece of hardware with some tweaks in the software of its predecessor. However, since there is no major change in design or any new wow features, one does feel a bit disappointed with the Galaxy S4. Just when they were edging past the iPhone, they seem to have lost steam…sigh.

Samsung Galaxy Camera in focus

The Samsung Galaxy Camera is an interesting product. It’s not a particularly revolutionary device, by which I mean, its not going to claim first to market on its head line features. It is not the first Android powered pure camera (Nikon holds that title) and its also not the first pure camera with wifi/wireless data connectivity. Even Samsung has several models in its stable with wifi connectivity. It is probably the first camera to feature 3G/4G connectivity on board, but phone cameras have been doing that for years. There are also plenty of cameras on the market with GPS sensors onboard.

What the Galaxy Camera does have is a compelling mix of features. Android as an Operating System has a pretty powerful set of applications for image editing, such as Photoshop Touch. Samsung already has experience in this arena, Photoshop Touch is one of the pre-loaded apps on the Galaxy Note 10, which is a pretty formidable mobile editing platform with its 10 inch screen and S-Pen, which has Wacom technology.

Galaxy Camera Editing

The device on the Hardware side is pretty much equivalent to the Galaxy SIII, using the same screens, CPUs and graphics processors. What this means in real world terms, is that any software development on the SIII (currently Samsung’s flagship, so commanding the maximum support from Samsung’s development resources) will technically be portable to the Camera with little effort. So it should be in line for updates right at the top of the tree. It beats the Nikon S800C Android camera in having Android 4 on board as shipped, compared to the Nikon’s 2.3 Gingerbread flavour.

On the Camera side, the sensor used is larger than a standard phone camera sensor, the lens is pretty decent with a f2.8 aperture at its widest, and covering a zoom range that covers the 35mm equivalent of 23mm to well over 400mm. This is a lot more than what was classed as superzoom compacts just a few short years ago. (Not currently, Canon’s current superzoom is a 50x zoom, 24-1200mm equivalent). The camera controls offer a decent amount of manual control. It has some innovative smart modes which will makes things easier for photo enthusiasts who want a certain effect, but don’t know manual controls get that effect manually.

Along with the good, there is a couple of bad. First up, lag. Rather than a snappy response, the camera app is reported to be a bit on the slow side. Now, this might be no worse than many of the current crop of point and shoot cameras, but this is what we have from the reviews. The other issue is the small battery. The battery is a rather small 1650mAh unit, quite a bit smaller than the battery on the Galaxy SIII phone. The battery is rated for 350 shots. Not too impressive by DSLR standards, but 300-400 shots is pretty normal for point and shoots. However, this camera also uses GPS, has a data transmission capability that, as experience with camera phones has shown, can kill a battery pretty quickly. Also, that big touchscreen can be used for things other than just as a viewfinder for taking pictures. It can be used for editing the pictures that have just been taken, and image manipulation is a rather processor intensive task, which in turn, drains battery.

But this is not just a picture and video tool, but a fully fledged Android device. Using Google Maps to find your way to what you are shooting, checking in with Latitude /Foursquare/Facebook, and then killing some time with Angry Birds, or watching a movie or listening to some music, there are many ways this camera can drain this small battery very y quickly.

Samsung Galaxy Sharing

On the pure camera front. the Galaxy Camera is equipped with a 16mp sensor. All well and good, but don’t expect this to be replacing a DSLR any time soon. As is typical from a high megapixel, tiny sensor camera, viewing images at 100% is pretty dismal. However,checking things out on the LCD, things look good, and for smaller images and just sharing online, it seems great.

And this really is the whole point of this device. Its not a professional’s tool, its a social tool. Why choose it over a regular smartphone? Well, the zoom range and pop up flash is much, much better than any smartphone. And with that comes the opportunity to get more done than with a smartphone. It is a trade off between the money you spend and the money you can earn. There are people that do live blogging and live video streams using iPhones, and this device can aim right at that market segment. As a bonus, you don’t use up your phone battery, so you can still keep in contact with people.

But do what, exactly? These things don’t come cheap. Costing over $600, it comes in at about the same price point as a base level SLR. So the trade off for losing the image quality is the ability to post instagrammed pictures on facebook immediately? Not to mention the system is pretty much stuck in a WYSIWYG mode. There aren’t any more extensions like you would have with an SLR, no external flashes, no filter systems, nothing like that. Like I said, this is not a professional’s tool, although it can be used to provide some services in certain situations.

In my last article, I looked into the CameraMator system. On the surface, it does seem to offer similar functionality, but it means adding a $300 price tag on top of the cost of a DSLR and accessories. However, its not just about sharing pictures on FB when looking at business opportunities. With something like the Galaxy Camera, simple social media is where it stops. With a DSLR, you can add a immediate high quality printing service. Follow up prints, blown up pictures. RAW control. External lights. Professional tools simply allow you to do more, and do it faster.

So in summary, the big question is, why should you get one? Why indeed? The thing is, it depends as much on your personality as it does on your requirements. As it currently stands, I would have bought one, since it does suit my requirements, but, not at this price point. For me, its too much money for what I am getting, so this generation, I’ll give it a pass. However, it is a segment that I would keep a close eye on for future developments.

Unofficial Android 4.2 Jelly Bean update for Galaxy S

Samsung Galaxy S (i9000) launched back in 2010. At that time, Galaxy S was the king of Android Smartphones; it featured a 4inch Super AMOLED display with 800×480 resolution, 512MB RAM, 8GB/16GB internal storage, 5 mega pixel camera with Geo-tagging and 1GHz single core Cortex A8 processor. It was powered by Android 2.1 Éclair with Samsung’s proprietary custom skin called TouchWiz version 3. Most of the Galaxy S’s internal parts are manufactured under Samsung’s own roof. The 1GHz Samsung’s Hummingbird processor had the best performing PowerVR 540 GPU inside, which can push up to 20 million triangles per second. One year later Galaxy S received the Android 2.3 Gingerbread update which made the device run super-fast. The device received many positive feedback and reviews. Down the line Samsung decided to put a stop mark on the Galaxy S, by not making it eligible for the ICS update. However, thanks to third party Android developers, this device didn’t die, cos after a few months CyanogenMod released a ICS update for Galaxy S which ran pretty well.

I have seen so many Galaxy S owners having installed ICS for their daily driver and they are really happy because they didn’t buy a new phone to experience the perks of ICS. Seems the development on Galaxy S didn’t stop there, as yesterday I saw a post in XDA developers forum that CyanogenMod released an Android 4.2 update for Galaxy S. It’s still beta version and some people have complained having trouble with WiFi, and for others the APN is not working. I’m pretty sure we can expect a stable release within a few weeks. I think this is a great chance for Galaxy S owners. So if you are geek enough to root your Galaxy S and if you know how to install a custom ROM then you must visit the below links.
