Samsung's fans and customers are potential buyers for Samsung Galaxy S4 too, so these must be given attention in the near future. The display is one of the issues for which Samsung was noticed in recent years, gaining more ground against the competition. So now we are expecting a display of 5 inches, compared to 4.8 inches on Galaxy S3, and a resolution of 1920 x 1080 pixels compared to the previous one of 1280 x 720 pixels.
The amount of RAM will double, reaching 2 GB instead of 1 GB, and the camera will switch from 8 MP to 13 MP with even higher resolution, both equipped with a secondary camera.
The operating system will also be upgraded, expecting an enhanced version of Android on 14th March, 2013. The 1.4 Ghz processor will be replaced by a 2 Ghz, and the browser will also be improved, passing from HTML to HTML 5.
Both will be equipped with eye movement recognition technology, noise dampening or cancellation, mapping, email, youtube and many other useful applications.
It will reache at 2600mAh battery, compared with the previous 2100 mAh, and my verdict is this: the new phone cost will fully deserve, because it can easily become a real personal assistant for you, with all these useful applications.
