Samsung launched the Galaxy A5 and Galaxy A3 as part of a new product line-up that was to mark the beginning of metal as part f design elements in Samsung smartphones. The first metallic phone was the Galaxy Alpha which is on sale in some markets, and was essentially a dip stick before Samsung gets more metal onto their phones. Samsung then launched the two, Galaxy A5 and Galaxy A3 which have a slight difference with Galaxy Alpha in that unlike all other Samsung phones, these two do not have a removable back cover.
Galaxy A5 has a metal frame that makes for the major design element and a non-removable back. SIM slots and microSD slots are on the side accessible via SIM tray.
The Galaxy Alpha is now on sale in China at a 2,5999 CNY or $420. This in no way means that the automatic price in other markets is going to be $420 but is a rough guide as to what to expect when it hits other markets. It wont be surprising to make it to the Christmas shopping list in many countries where it will sell. Target market is the more aspirational youth that wants a good looking phone while at the same time ensuring that they can afford it.
Galaxy A5 is a 5 inch HD Super AMOLED display device with a 1.2 GHz Quad Core processor, 16GB internal memory expandable to 64GB via microSD, 2GB RAM, 13MP rear camera and a 5MP front camera. The battery is 2300 mAh and comes running Android 4.4 KitKat out of the box. See here for the full specs sheet.
