The Samsung i7500, known as Samsung Galaxy in some countries, is the first mobile phone manufactured by Samsung that uses the open source Android operating system. It was announced on 27 April 2009. It is succeeded by the Samsung i5700.

Features:
The i7500 is a 3.5G smartphone, offering quad-band GSM and announced with tri-band HSDPA (900/1700/2100) at 7.2Mbps (however, Samsung's official pages for the Danish, Finnish, Norwegian and Swedish versions only mention dual-band UMTS 900/2100). The phone features a 3.2-inch AMOLED capacitive touch screen, a 5 Megapixel autofocus camera with power LED flash, and a digital compass. Unlike the first Android phone, the HTC Dream (the G1), the i7500 has a standard 3.5mm headphone jack, and a Directional Pad in place of a trackball.
Software-wise, the i7500 offers a suite of Mobile Google services, including Google Search, Gmail, YouTube, Google Calendar, and Google Talk. The phone's GPS enables Google Maps features such as My Location, and Google Latitude. It also supports MP3, AAC (including iTunes Plus downloads) (only the codec, not the .acc format), and H.264 video. A beta version of the Spotify music streaming service is also now available for this phone via the Android Marketplace.
