Samsung Galaxy S IV being introduced on March 15th and then launching in Europe during the next month. The device would then rollout to the Americas, Australia and Africa in May and June. That gap in time between the introduction and the eventual U.S. launch would equal what was seen for the Samsung Galaxy S II and the Samsung Galaxy S III. Samsung expects to see sales of the new phone reach 100 million units.
Murtazin's tweet also mentions that HTC will miss HTC One sales in 2013, like it did in 2012. It is not entirely clear whether the reference is being made to the new HTC One, expected to be introduced on February 19th, or to the current HTC One lineup which includes models like the HTC One X+, HTC One X, HTC One S and HTC One V. Either way, the comment by Murtazin does not sound good for Taiwan based HTC. While the HTC DROID DNA/HTC Butterfly has impressed with its 5 inch FHD screen and 441ppi pixel density, the competition at the high end of the smartphone market is fierce. The upcoming HTC One is expected to offer a 4.7 inch FHD screen which would work out to an industry leading 468ppi pixel density.
