Samsung Galaxy Mini

The Samsung Galaxy Mini (GT-S5570[B/L/i]) is a smartphone manufactured by Samsung that runs the Android operating system. It was announced and released by Samsung in early 2011. In some markets it is known as Samsung Galaxy Next/Pop/NG, while it is sold in the United States as the Samsung Dart exclusively for T-Mobile. It is currently available in four different colors; steel grey, white, lime and orange. With this release, the face buttons were changed to capacitive touch, matching the rest of the Galaxy lineup.

It was succeeded by the Samsung Galaxy Mini 2, featuring better screen (480x320 high contrast type vs old 320x240), higher clocked processor (600 vs. 800 MHz), and drastically improved memory (278 vs. 384 MB of RAM; 160 vs. 1830 MB of internal storage available) over the original, as well as Bluetooth v3.0, Wi-Fi Direct & NFC support, among others.

Features
The Galaxy Mini is a 3.5G smartphone that offers quad-band GSM and was announced with two-band HSDPA (900/2100 MHz) at 7.2 Mbit/s. The display is a 3.14 in-diagonal TFT LCD with a 240×320 pixels QVGA resolution supporting up to 256,000 colors.

The Galaxy Mini is presented as an entry-level smartphone, and is (as of 13 May 2011) one of the cheapest Android phones on the market.

The Galaxy Mini originally ran on Android 2.2 "Froyo", but in May 2011, Samsung announced that the Galaxy Mini (along with other Galaxy models) will get an official upgrade to Android 2.3 Gingerbread. An official upgrade to Android 2.3.6 (Gingerbread) was released via Samsung Kies on 9 December 2011 for some mobile operators. The Galaxy Mini can also be flashed with custom ROMs such as CyanogenMod releases (although not officially supported by Samsung) where it is codenamed tass. The officially supported version of CyanogenMod on the Galaxy Mini as of August 2012 is CyanogenMod 7.2. It will run CyanogenMod 10/10.1/10.2 and even 11, but it is not officially supported, so there may be stability or performance issues, especially in the latter case.

It can be overclocked to 800 MHz with SetCPU.
