The Galaxy Tab features a 7-inch (180 mm) TFT-LCD touchscreen, Wi-Fi capability, a 1.0 GHz ARM Cortex-A8 ("Hummingbird") processor, the Swype input system, a 3.2MP rear-facing camera and a 1.3 MP front facing camera for video calls—running the Android 2.2 (Froyo) operating system.It supports phone functionality (as speaker phone, via provided wired ear piece or Bluetooth earpieces.), except those sold for US market. However, these tablets can still download videoconferencing app such as Qik or Fring as alternative.
The Samsung Galaxy Tab also has a 30-pin docking/charging connector that is very similar to the PDMI connector, which is a standard, non-proprietary alternative to Apple's docking connector. Actually, it is so similar to the PDMI connector that it is widely mistaken for it, but Samsung has changed it sufficiently so that it is non-standard.
The Samsung Galaxy Tab connector pins are upside down compared to the Apple iPhone 30 Pin Connector. While Apple connectors look like they may fit they don't. The inside pins on the Galaxy Tab connector are flat and also positioned vertically not horizontally, this makes soldering wires to the connectors difficult. PodGizmo has designed a breakout board called the Samsung TabBreakout that allows easy access to the pins on the Samsung Galaxy Tab connector.
