Sanyo Katana DLX Cell Phone Review - Software

Alfredo Padilla
Published on August 06, 2007 Comment on this






OS (3.0)

The Katana DLX uses Sanyo's proprietary operating system. We found it to be fairly intuitive, with a good selection of options and features. We especially liked having the customizable favorites menu on the home screen, which gave us access to the programs or features of our choice, much like a Windows Mobile Start menu. Our biggest concern about the interface was that menus can get rather large, with unintuitive sub menus. We also found that the interface was slow in places; this is especially evident in the music program, which takes forever to launch. The operating system does not support multi-tasking either; if you're browsing the Web you can't access any other program without first exiting the browser. Overall, we judge the Katana DLX's operating system to be pretty run of the mill. Our score for proprietary operating systems tops out at five points, with higher scores being reserved for more advanced smart phone operating systems.

Home Screen Score (4.0)
The Katana DLX home screen provides good functionality. As we mentioned above, the left soft key is assigned to a favorites list that can be edited by the user for easy access to their favorite applications. In addition, the home screen itself lists four shortcuts which are not user configurable; Main Menu, On Demand, Music, and New Text Message. The home screen can change significantly depending upon the theme you are using. The Sanyo theme lacks the four shortcuts and instead uses user definable shortcuts for each of the four directions of the D-Pad, while an e-mail theme replaces the music shortcut with an e-mail one that gives you basic information about your e-mail accounts.

In addition to these shortcuts the home screen displays the time, date, and the current ringer setting. Along the top are indicators for various items like signal strength, battery, Bluetooth status, and a variety of other indicators that become active when they are necessary. The left soft key is assigned to contacts, and neither soft key assignment can be changed by the user. The background on the home screen can be changed, however this can only occur in the "Sanyo" theme. The other theme's home screen backgrounds cannot be changed. We found the home screen on the Katana provides useful functions, and we like the ability to change the look and feel via themes. We didn't like that the indicators along the top can get rather crowded at times, and that except for the "Sanyo" theme we can't change the shortcuts or background picture on the home screen.

Extensibility (3.0)
The Sanyo Katana DLX does not support native third party applications, you can only extend the phone's capabilities by using Java applications. Although there is a growing selection of such applications, like Google Mail or Opera Mini, they can be slow to load and don't have access to all the phone's capabilities. However, the Sanyo Katana is not a smart phone, and most people interested in the phone probably aren't considering extensibility.

Customizability (4.0)
The Sanyo Katana offers a pretty extensive selection of customization options, maybe too extensive. In addition to the home screen customizations and themes we mentioned above, you can also change font size on the exterior screen or in the messaging and browser applications. You also have a variety of small modifications you can make, for example changing the background shown for incoming calls. These small changes are peppered throughout the Settings menu, which we found confusing. We would have preferred a single customization section where you can access all these options.

OS Responsivness (3.0)
As we mentioned above, we found the Katana DLX's interface could slow down significantly when launching programs. Moving around menus is generally zippy however, and once an application is launched it also responds fairly well. Still, it's annoying to sit around and wait while the music application or Web browser launches.

Browser Features (5.0)

The browser found on the Katana DLX is a simple Wap 2.0 browser. It is capable of displaying both WAP and HTML pages, as well as images and Javascript. It also supports cookies, as you would expect from any mobile browser nowadays. It does not support more advanced features like Java, Flash, RSS feeds, saving Web pages or images, and password management. There is only limited encryption available, so I wouldn't expect to do your banking on the Katana DLX.

Browsing Interface (4.0)

Katana DLX Bookmarks Katana DLX Browsing History

Web pages are automatically reformatted by the Katana DLX's browser to fit on your small screen and minimize left/right scrolling. The directional pad moves from link to link, which means on link heavy pages you won't be able to move around very quickly. You can easily create favorites, however favorites are organized into a simple list in the order they are created. There is no support for folders, but you can edit existing bookmarks. We were happy to see browsing history is saved between sessions, but you won't get anything more than a simple chronological list of pages here. While browsing, the left soft key allows you to select a highlighted link or edit a highlighted field. This is redundant because the center select button performs the same function. The right soft key opens a menu where you can access a variety of functions. If all you're going to do is visit a few mobile sites, the Katana DLX's browser will do you fine, but if you want to actually experience the Internet on your phone we recommend you install Opera Mini.

Browser Access (5.0)
To test how easy it is to access the Web browser on the Katana DLX, we count how many steps it takes to go from phone closed until we have browsed to our Web site. We use steps instead of a timed test in order to take network issues out of the equation. Typing out the URL is counted as a single step. The Katana DLX took eight steps to complete this process. As you can see from the table below, this is faster than most phones and as good as the Nokia N75, a smart phone you would expect to quickly be able to access the Internet.

Cell Phone Steps Score
Sanyo Katana DLX 8 5.0
Nokia N75 8 5.0
Sprint Upstage 13 3.08
Motorola Krzr K1m 14 2.86
Sanyo M1 13 3.08
LG Chocolate VX8550 12 3.33

Gaming (3.33)

As with other phones we've seen from Sprint (including the Krzr K1m and Sanyo M1), the Katana DLX only has a few demonstration versions of Java games pre-loaded. Once again we feel this is pretty cheap, we expect phones to ship with at least one full version game. The controls on the Katana DLX did well in playing the demo versions of the games, with an easy-to-use and responsive directional pad and well-differentiated soft keys leading to accurate game play. The Katana DLX only supports Java games, however there is a good selection of such games available, including popular titles like Tetris and Sudoku.

Calculator (5.0)

The Katana DLX's calculator is extremely basic. The directional pad is used to access the four arithmetic functions (Addition, Subtraction, Multiplication, and Division) with the center select key assigned to equals. The left soft key can be used to insert a decimal point, and the left will clear the calculator. No advanced features are available, however it is very easy to use.

Alarm (7.0)

We're very happy with the Katana DLX's alarm functionality. You can set up to five separate alarms and decide which ones are on or off at a given time. Each alarm can also be assigned to go off once, on any given day of the week, all weekdays, or on weekends. The alarm settings also allow you to set how long the ringer sounds, snooze intervals, and how many times an alarm can be snoozed. This functionality is as good as any smart phone and better than some, like the Nokia N75 and other Series 60 devices.

Document Software (0.0)
The Katana DLX does not include any document viewing or editing software.

Other Software (1.0)

In addition to the software we've discussed above, the Katana DLX has one additional piece of software we considered significant enough to award points; a file browser. File browsers are extremely useful, as they allow you to easily view the files on your device and move or copy them, functions which are often left out of program interfaces used to view the files.
