Tab 7 F-GT

The Samsung Galaxy Tab is an Android-based mini-tablet computer produced by Samsung introduced on 2 September 2010 at the IFA in Berlin.

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 a 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.

Hardware

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 does not 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).

The proprietary 30-pin docking and charging connector is not shared with other manufacturers. This connector appears very similar to the standard PDMI connector (a non-proprietary alternative to Apple's docking connector) and is sometimes mistaken for it, but it is non-standard and all accessories, including charging cables, are incompatible with other equipment and only available from Samsung.

Samsung says that its 4000 mAh battery will give it 7 hours of video playback or 10 hours of talk time.

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).

Software

This tablet comes with a version of the Android 2.3 (originally 2.2) operating system with some custom skins and applications. Most Android 2.2 apps developed using Google's guidelines for Android should scale properly when displayed on larger-screen devices such as the Samsung Galaxy Tab, according to Samsung. Adobe Flash 10.1, DivX, MPEG-4, WMV and Xvid, H.263, H.264 support has also been announced. The Tab uses Atmel's maXTouch multi touch capacitive touchscreen, and supports multi-tasking.

The Tab supports calendar, email and instant messaging applications. It has a launcher for e-reading applications which starts PressDisplay when reading newspapers, Kobo when reading e-books, and Zinio when reading magazines. For viewing and editing Microsoft Office documents, the Galaxy Tab also comes bundled with the Android version of ThinkFree Office Mobile.

The Tab can also provide tethering, acting as a Wi-Fi hotspot for up to 5 devices. Stored addresses can be displayed in Google maps with one click. It also allows linkage with a contact's Facebook profile if the phone address is linked with the contact's Facebook address.

Several HD video content multimedia formats, including DivX, XviD, MPEG4, H.263, H.264, are supported. It can play video content either stored on the device itself or streamed from YouTube, and can output 720p video to a TV either as composite video or via HDMI when using the optional dock.

Text can be entered using Swype, by tracing a path over letters on a virtual keyboard, and standard XT9 predictive typing is also supported.

TouchWiz Samsung Galaxy Tabs allow the screen display to be saved. Honeycomb tablets without TouchWiz, including the 10.1 in Galaxy Tab, must either be rooted or have the SDK installed in order to capture screenshots.

Hundreds of thousands of mobile apps, the majority being free, are available from Google Play.

Upgrades

In May 2011 it was reported that Android Gingerbread 2.3.3 was being made available in Italy, with other regions expected to follow.

Several updates have been made throughout the world and in February, 2012, android version Gingerbread 2.3.6 is available.

Security and privacy

Early impressions and reviews

Some published early impressions were favourable, and the Tab was considered a serious rival to the iPad. "Rough edges" which should improve with later software updates were commented on.

Other early reviews were more critical; one reviewer commented "The Tab ... [merges] the worst of a tablet and the worst of a phone."

Sales

A week after its release, Samsung announced that they had sold 600,000 units. On the 4 December, it was reported that the 1 million mark was reached, two months after launch. However, an executive at Lenovo claimed that Samsung had only sold 20,000 out of the 1 million Galaxy Tabs that were shipped. In January 2011 Samsung announced they had shipped 2 million units to stores. In August 2012, actual sales figures were released in the patent infringement court case against Apple showing that a total of 725,000 Galaxy Tabs were sold through Q2 of 2012.

Successor models

During the 2011 International Consumer Electronics Show (CES), Verizon Wireless and Samsung Telecommunications America (Samsung Mobile) announced that a new 4G LTE-Enabled Samsung Galaxy Tab features access to Verizon Wireless' 4G LTE Mobile Broadband Network and a 5 megapixel rear-facing Camera will be available.

The first successor to the original Galaxy Tab is the Samsung Galaxy Tab 7.0 Plus. This model features the same 7" screen with the same resolution of 1,024 x 600, and uses a PLS panel. Also it now comes with Android 3.2 Honeycomb pre-installed as well as including newer, more powerful hardware. The new model includes a 1.2 GHz dual-core processor, 16GB or 32GB of user accessible flash storage, and a 2-megapixel front and 3-megapixel rear-facing camera. The device is much smaller than the original, measuring 193.5 x 122.4 x 9.9 mm and weighing just 345 grams.

The latest tablets in the series are the Samsung Galaxy Tab 2 (7.0) and (10.1) and are aimed at budget markets. The front facing cameras have been downgraded to VGA quality, the chip set is now a TI OMAP4430 1.0 GHz dual-core, and is slightly thicker. In addition, the 5GHz WiFi has been dropped. The 10.1" version retails for $399 and the 7.0" version retails for $249.

At the Mobile World Congress 2012, Samsung announced the Galaxy Note 10.1, as an alternative to the Galaxy tab 10.1, it has a 10.1-inch display and uses a quad-core 1.4 GHz processor and supports the Samsung S-Pen input as seen on the original Galaxy Note phone.

Advantages and Disadvantages on Samsung Galaxy Tab 7.0 Plus

 

Samsung has launched the next generation Galaxy Galaxy Tab P1000 is 7.0 Plus.Here is a short review about the Advantages and Disadvantages on Samsung Galaxy Tab 7.0 Plus.

  Advantages :

As the next generation Galaxy Tab the first version, not much changed from the design side. There are several elements is maintained. Such as shape and design (exterior) with the same 7-inch screen. 

 

Significant changes occurred in the processor jeroannya now Dual Core 1.2 GHz so that automatically improve their performance to be faster.

 

Subsequent changes is an operating system that has been put on the latest version of Android 3.2 (Honeycomb). The platform has been optimized specifically for 7-inch screen. This is interesting because almost all of the outstanding Honeycomb tablet has a 8.9 inch screen and above. Galaxy Plus 7.0 is the first 7-inch tablet with Honeycomb operating system. The result is an application for smartphones (small screen) automatically perform optimally in these tablets, as well as specialized applications that perform well Honeycomb. User interface can also be personalized thanks to Live Panel.

And that is not less important, now users can directly call without having to use handsfree or Bluetooth. It may seem strange to call a device that size, but could have much to do that later will thus become the norm.

Disadvantages :

Although sophisticated and added many new features, this tablet was not free from shortcomings. There are at least three points deficiencies we encountered in a short review. First, the camera which was reduced from 5 to 3 Mpix Mpix. This of course affects the quality of the images obtained.

 The next shortage is no softkey menu buttons below the screen for operation.Although not very significant, but the old tablet users need time to adapt and may even be confused for the first time use. These tablets use navigation menu that blends the typical honeycomb inside the screen at the bottom and often hidden when running the application. Menu for calling and messaging is also hidden by pressing the arrow icon below to show it making it less efficient.

In addition, the new tablet is actually not included Gorilla Glass. Though the technology is essential to protect the screen from impact and scratches. So you should be more careful when wearing it.
