The Samsung Jet comes running the TOUCHWIZ 2.0 user interface, although rather dated by today's TOUCHWIZ 3.1 and soon to come TOUCHWIZ 4, in 2009 TOUCHWIZ 2.0 was the latest UI, and the only notable deficiency is that it is not as good looking as the newer UI's and lacks multiple homescreens or multiple menu screens.
So the setup is pretty basic, you get three non-negotiable home screens, with the widget bar to the left. You can have as many widgets as you like per home screen, but overlapping of home widgets will make it difficult to swipe across the home screens, you might accidentally touch a widget. The main menu is divided into three screens as well, you cannot add more or rearrange icons, but all applications are laid onto the main menu with the deeper digging reserved for the downloaded Java apps and the Settings menu.
There are three basic views across the Gallery; Graphical, Grid and List. The file manager is flawless, it shows items from the memory card and internal memory in an integrated view, you can choose to turn off this option, it automatically locates and stores media types, though you are free to ignore this and arrange them as you wish.
The moving or copying option works smoothly without glitches or any problem at all, there are two (technically three) picture galleries, one is opened when any folder containing pictures is accessed, the other is a dedicated gallery and the final gallery is from the Motion Gate or 3D Cube depending on which you access. Speaking of the 3D Cube and Motion Gate, here is an explanation as to what they are.
The Samsung Jet has very sensitive accelerometer, actually it's a combination of an accelerometer and a gyro-scope, so it can detect almost 4 dimensions of movement. Remember that second rocker button we reviewed in the Design section? This is where it shines. Holding the slightly raised part of the rocker launches the 3D Cube, a cube with all six media centered options presented in a very responsive and interesting fashion, flicking your finger across the surface the cube rolls around almost like a ball, the selectable options are; Videos, Music, Games, Pictures, Web and FM Radio. The 3D Cube is actually named Media Gate.
Now for Motion Gate, which is completely different from Media Gate aka "3D Cube", now pressing the other rocker button launches Motion Gate, which presents your; last song, last movie, last contact, last picture and last game. In short it presents the last set of items that were being used, unlike the 3D Cube, Motion Gate, as the name implies, relies on the accelerometer to move around.
By flicking the phone either to the left or right, you can select whatever option you please. Although it is fun to use, it is almost completely devoid of any practical purpose, it's just there so you can show off to your friends. All items in either Media Gate or Motion Gate are presented in their own unique 3D galleries, they are not shortcuts to the main menu. If you find any of this too complicated, Samsung have included a very entertaining tutorial in the Jet.
Now to shine some light onto the resistive screen, some of you might be thinking that having a resistive screen would ruin the whole experience of using the Jet. In actual fact the resistive screen of the Jet is the single most responsive resistive screen I have ever come across in over 7 years of touchscreen phone reviewing. It easily rivals the original iPhone and most mid-range capacitive screens, yes believe it or not the resistive screen feels like a very good, if slightly slow iPhone 3GS screen. So the chances of you noticing it is a resistive screen without being informed beforehand are virtually zero. The added benefit is that you can use the screen with anything, gloves, a pen, fingers, metal and anything else you like.
Now the phone book has a limited capacity of 2,000 contacts, which is a bit of letdown really, the Jet was doing so well I took limitless capacity as granted. But it does have photo tagging, ringtone tagging, video tagging and multiple field entries. There is an alternative to the phone book, however, the Photo Contacts application. It presents over 2,000 contacts via pictures in a very 3D-like gallery, think of it as the the picture gallery for contacts. It might not be practical, but it looks very cool.
Now for the Jet's messaging capabilities, it has a shared editor for SMS and MMS, E-Mail uses a separate editor, the three available text input options are D-Pad, QWERTY (simply flip the phone into landscape mode) and Handwriting. The handwriting recognition is phenomenally accurate and writing hand written messages is a complete breeze. Now for the native e-mail client, this is one place where the Jet takes second best prize, unlike smartphones and most other feature phones, your IMAP and POP3 information has to be entered manually, which is rather irritating. Other than the e-mail settings issue, the client is excellent.
Finally it should be noted the entire UI is silky smooth, there is never any lag or stutter, at all. Even when the Media or Motion Gates are active.
