The Samsung Galaxy Tab is an Android-based tablet computer produced by Samsung introduced on 2 September 2010 at the IFA in Berlin. The Galaxy Tab 7.7 that’s got us really excited. The device is the latest entry in Samsung’s popular Android-based Galaxy Tab line, and the thing is pretty darn slick. The 7.7-inch screen is in keeping with the company’s push toward devices that straddle the line between the tablet and smartphone spaces and it is indeed a terrific form factor.

The Samsung Galaxy Tab 7.7 might be the first Super AMOLED Plus-screened tablet to launch, but it was beaten into second place here at IFA 2011 by its littler sibling, the Samsung Galaxy Note. Below are the specifications of Samsum Galaxy Tab 7.7.

The most remarkable thing about Samsung’s latest gen tablets is that they seem light years ahead of the original Samsung Galaxy Tab that debuted at last year’s IFA.

Given the price point of the 10-inch Galaxy Tab, you have to hope this will be the Android tablet to come in at a reasonably lower price point than the iPad 2. As ever it’s all about the price point, but either way this is a fantastic device, as is the Galaxy Tab 10.1

The WXGA screen has superb colour reproduction and is hugely impressive in terms of viewing angle. If a 9-inch plus tab represents a workhorse device, this metallic unit is truly a portable entertainment screen. It’s scary how thin and portable this thing feels. And it’s every bit as capable as larger tablets – not least due to the remarkable feat of retaining a 10 hour battery life.

The Galaxy Tab 7.7 is too big to be pocketable, but it’s totally portable and supports 3G/HSDPA as well as microSD up to 32GB. There’s also capability for Full HD 1080p playback as well as DivX encoded footage.

As with the Samsung Galaxy Note, Android has been overlaid with Samsung’s latest version of TouchWiz – TouchWiz UX. Optimisation work has taken place to ensure that apps designed for different sized screens still feel at home on the Galaxy Tab 7.7.

Like so many other devices launched by Samsung this year, the screen is the thing, and indeed, that 7.7-inch 1280 x 800 Super AMOLED Plus display is quite sharp and extremely bright. In fact, we had to turn the thing down while doing the below hands-on video. Also new with the device is the addition of Android 3.2 . We didn’t notice all that much different on that front, however, seeing as how the tablet is still skinned with the familiar TouchWiz UX UI. There weren’t really any noticeable changes from the newly updated version for the 10.1.

The Galaxy Tab has a 7-inch (180 mm) TFT-LCD touchscreen, Wi-Fi capability, a 1.0 GHz ARM Cortex-A8 Samsung Exynos 3110 (code-named “Hummingbird”) processor, the Swype input system, a 3.2 MP rear-facing camera and a 1.3 MP front-facing camera for video calls. It runs the Android 2.2 (Froyo) operating system and supports telephone functionality as speaker phone, via provided wired ear piece or Bluetooth earpieces (except models sold in the US). It can download videoconferencing apps such as Tango as alternative to telephone functionality.

The tablet is enclosed in a plastic frame that makes it lighter than other metal-bodied tablets, weighing 380 g (0.84 lb).

The GT-P1000 model carries a 7″ Super TFT instead of the AMOLED which is used by Samsung in its Galaxy S phones.The screen has a 1024×600 resolution With mDNIE (Mobile Digital Natural Images Engine). Internal flash storage of 2 GB (North America CDMA models), 16 GB or 32 GB can be supplemented with a microSD flash card with up to 32 GB. CPU is a Exynos 3110 Applications Processor (Also known as Hummingbird) features 1.0 GHz ARM architecture Cortex A8 application and has 512 MB of RAM paired with a PowerVR SGX540 graphics processor.

The WIFI only model has a different graphics chip that doesn’t support TV out and Samsung has not provided (or promised to provide) an update to gingerbread.

The tablet has two cameras: a 3.2 rear MP camera with a LED flash and a 1.3 MP front camera for video calling (the Verizon model has a 3 megapixel rear camera). The front camera has auto focus capability. The camera also has auto image stitching, combining 8 pictures. Modes include single shot, continuous, panorama, and self-shot. It can automatically trigger on detecting that the subject smiles. Autogeotagging uses the internal GPS receiver.

The tablet has GPS, 802.11n Wi-Fi, Bluetooth 3.0, and handsfree/bluetooth/headphone telephony. Cellular protocols include GSM CDMA, HSPA (HSUPA).

It also has a 30-pin docking and charging connector very similar to the standard PDMI connector (a non-proprietary alternative to Apple’s docking connector). It appears so similar to the PDMI connector that it is widely mistaken for it, but it is non-standard and all accessories, including charging cables, are incompatible with other equipment and only available from Samsung.

The GSM variants of the Galaxy Tab have an externally-accessible SIM card slot. If the SIM card is removed while the system is on, the system automatically reboots. The AT&T and T-Mobile variants of the Galaxy Tab ship with a micro SIM in a micro SIM adapter. For non-US Galaxy Tabs, with phone function, this slot can also accommodate a 3G data-only SIM card if the user does not need telephone functionality.

The Samsung Galaxy Tab also has an optional RCA plug connector through which the screen image is shown on a TV or other display (the Tab’s own screen cannot be turned off; it can be dimmed with a backlight dimming app).

Looking for the new features from Samsum Galaxy 7.7, it will interest many consuments later. What is your opinion??
