Faster, thinner and slightly lighter, Samsung reveals Galaxy S4
Out 'end of April'
It boasts a 4.99-inch, 1920 x 1080 pixel 441 ddp resolution Super AMOLED screen using Gorilla Glass *3.
Samsung hasn't specified the chipset, as this will vary between markets - either an 1.9GHz quad-core processor or an 1.6GHz octa-core processor.
There's a 13MP back camera plus a 2MP front-facing camera.
Dimension-wise, it's sized 136.6 x 69.8 x 7.9mm and weighs 130g.
Galaxy S4 runs Android 4.2.2, and comes with 2GB of DDR3 RAM, and 16, 32 or 64GB of storage (depending on markets), plus up to 64GB via microSD.
Coming next month
Initially presented in Black Mist and White Frost (with additional colours to follow), the phone will launch at the end of April, in 155 countries and with 327 carriers, although presumably not all on the same day.
Pricing hasn't been announced yet.
In terms of gaming, Samsung didn't break out many details, other than to point out that its Group Play feature will enable multiplayer gaming, as well as the sharing of games (photos, music, video etc).
The Galaxy S4 will also come with preloaded games that can be shared in this manner, while Samsung's opening up the Group Play SDK to encourage "more partner development companies to develop various types of games in the future, further embracing its philosophy of innovation conceived by people in order to inspire them in return".
(Whatever that means.)
More generally, the Galaxy S4 features plenty of new software options in terms of improving your photos, such as a burst mode that the camera will automatically then select and collage between to improve the final shot, photos and video that use both the front and back cameras, and plus various health, banking security, translation, and multimedia content services.
