The Galaxy S4 promises an impressive and energy efficient 4.99-inch 1920x1080p FHD resolution which is slightly larger than the Galaxy S3's 4.8 inch display.
Some markets will get QI Wireless Charging in their Galaxy S IV
As it turns out the Samsung Galaxy S4 flagship comes with support for the Qi wireless charging standard. Samsung said nothing about this at yesterday's event in New York, but some observant guys found wirelessly charging Galaxy S4 units at the stands after the show.
The charging pads match the Galaxy S4 colors - the base is made of the same glossy plastic as the smartphone, and the top op pad has a rubberized finish to hold the Galaxy S4 securely.
Unfortunately, the support for the wireless charging feature will depend on your region and your carrier. So you'll have to look carefully if the Galaxy S4 you are about to purchase comes with wireless charging out of box or not.
The good news is the wireless charging will most probably depend on the battery cover, so even if you will get a Galaxy S IV without wireless charing support, you'll probably be able to purchase the cover one separately, and extend your device easly. But, time will tell ...
