Sprint Summer 2006

Samsung A640 Sanyo Katana 2400 & A420 Comments  28

Hands-on with Sprint's basic phones for summer: the Sanyo Katana and 2400, and Samsung A640 and A420.

Sprint this week rolled out a quartet of basic new phones for summer. They're not high-end phones with EVDO, but each phone serves a purpose in Sprint's full lineup.

The Samsung A640 is a rather sleek clamshell phone with a slick OLED outer display that disappears into the glossy black front when it's not shining. The sleek black front echoes LG's popular Chocolate phones.


Its features are mostly basic. The OLED outer display is multi-color, not full-color. That means the blue parts will always be blue, the red parts always red, etc. Unfortunately, the outer display seemed rather dim to us. OLED displays are usually very bright, but this one seemed to be the exception.

The main display is rather small at 128 x 160 pixels. The camera is only VGA resolution. However, the A640 does have Push-To-Talk and Bluetooth going for it.


It's on the small and light side, but not exceptionally so.

Both the Samsung A640 and A420 have a new high-contrast main menu option for those with poor vision:


While Sprint is marketing this feature as a major innovation, it's really nothing more than a very simple main menu theme. It would have been nice to see larger fonts throughout the menus and phonebook, for example. Unfortunately this doesn't include that.

razr copycats

why would anybody else bother copying the RAZR? the RAZR is so common, they should spend more time finding a successor to the razr instead of trying to copy it.
yea i know. and its not even a good razr copy. no bluetooth and a vga camera?? it also looks thicker than the verizon razr.

does anyone know who thin the katana is?
When the razr was developed, it was a good idea that spiraled into a revolution. The "thin phone" design is now as common as say a "bar" phone design, or a "slider" design. Its almost a wireless suicide if you do not offer a "thin phone". thus..

Other features


aside from the lack of EVDO and only sporting a VGA camera, what else does this phone have? does it have speakerphone, music player, or anything else like that, or is it just a basic sanyo phone that was crammed into a slimline body?

Mistake on my part...

...as I thought Sanyo wouldn't think of releasing the Katana without EVDO built in. Looks like I'm eating crow.
So will sanyo.

Katana Ports?

Rich, what kind of data port did the Katana have? Did it have the standard sanyo port, or a mini USB port like the RAZR.
It's the sanyo port, at least that's what it appears to be on the dummy.

Sorry about the quality

Thanks to Amtrak, I was a full 90 minutes late for the event last night. That didn't leave me with as much time as I had hoped with the new phones. That's why there aren't as many details or photos as we usually try to put in our In Depth articles.

Also, my Canon camera is busted, so I was stuck with my crappy backup camera. That's why the photos aren't quite as good quality as we usually strive for.

I hope the article still provides some useful info and eye candy for folks.

Please feel free to ask questions.
no worry it was still heart felt 😢


does the katana have that click that all other sanyo's have when you flip it open or closed?
Compared to the motorola razr, how is the size and width?

Fall EV-DO Push?

You guys mentioned a slew of new EV-DO handsets comming in the article on the front page.

Any more details on these devices?
It's a raft, even, of new evdo phones. I am curious, definitely.
The Sanyo 8400 is one. Samsung A720, M250 and M500... that's all that springs to mind at the moment, although there may be more.

Nothing exciting in summer...

I'm still waiting for Sanyo to catch up with Samsung and get (micro)SD, Bluetooth and EVDO all in one great package...

My Samsung a920 works ok, but won't sort my SMS messages into folders. And it won't let me add words to the T9 feature, which includes some useful common spanish words but misses a few obvious English ones. Starting movies takes about 15 seconds longer on the a920 than the Sanyo 5600, and if you get a call while watching, well, get ready to start the movie over. After you get done fast-forwarding up to where you left off, at least it has a rewind button to correct when you skip too far, unlike the Sanyo. But every time I've used it like this, its frozen the player, and I had to take the battery off to reset the phone. ...
