Samsung sold 10 million GS4 phones in less than a month, and the GS4 was Samsung's fastest selling phone. But now analysts claim that orders are slowing down, and Samsung lowered its monthly supply orders to 7-8 million units down from 10 million. They say that demand in Korea and Europe is "weak".

Samsung recently launched new "mid-range" phones (such as the GS4 mini) and this may be cannibalizing flagship smartphone sales. Samsung originally hoped to sell over 100 million GS4 units, perhaps they were too optimistic. - or double the GS3 sales. The GS4 is currently available in more than 110 countries and will be rolled out to a total of 155 countries soon.

According to DisplaySearch, AMOLED phone panel shipments will reach over 217 million units in 2013 (up from 134 million in 2012), and AMOLED supply/demand ratio will fall to 1% in Q4 2013 - which means that supply disruptions could lead to shortages. The GS4 displays will represent almost half of all AMOLED panels sold in 2013, so if Samsung won't reach its target this may change DisplaySearch's estimates drastically.

The GS4 features a 4.99" Full-HD (1920x1280, 441 PPI) Super AMOLED display, an Octa-core (Quadcore in some models) 1.6Ghz CPU, 2GB of memory, 13 mp camera and a 2,600 mAh battery. The GS4 includes a lot of new software features and special UI controls, include the Adapt Display which allows extensive display calibration adjustments.
