Samsung Intensity U450 Review

Samsung Intensity U450 Review

Over the past few months there have been quite a few QWERTY keyboard messaging phones released by Verizon, such as the Samsung Alias 2 U750, LG enV3 VX9200 and enV Touch VX11000, and the Motorola Rival A455. Most recently Samsung introduced the Samsung Rogue U960, which we have reviewed, and the Samsung Intensity U450. Even though both of these devices have a sliding QWERTY keyboard, they are geared to different audiences. Primarily the Rogue is a high-end feature phone that appeals to a consumer wanting a touchscreen device with a lot of added features, while the Intensity is more for the average consumer who is looking for something more basic. The Intensity has tough competition from the LG enV3 and Motorola Rival  as both offer similar features, even though the enV3 would be considered the top-model of those three phones.

Included in the retail package is the Samsung Intensity U450 phone, 960 mAh battery, wall charger with detachable data cable, and user manual.


The Samsung Intensity U450 is offered in two color choices: Flaming Red and Grey. Even though the device weighs less than the Motorola Rival and LG enV3, it is still slightly taller, but the rounded edges don’t make it feel that way. Unfortunately, the overall plastic construction is somewhat cheap feeling, though not as bad as the Rival, but still not as good as the enV3. When sliding the Intensity open and closed you can hear the keyboard rubbing against the plastic behind the display. Also, the battery cover just snaps on and off and feels like it could break quite easily. Because of this, we’re not sure what the long-term durability of the Intensity would be, but we’d be surprised if it would hold up to any more than a year or two of normal use.

You can compare the Samsung Intensity U450 with many other phones using our Size Visualization Tool.

The Intensity features a 2.1-inch 176x220 resolution TFT display that supports up to 65K colors. Since it is smaller than the main display used by the Alias 2 and enV3, and has a lower resolution, images and text don’t look that great. In addition,  it is completely unviewable while in direct sunlight. Below the display is the circular d-pad, left and right soft keys, send, end, back and speakerphone keys. They are all rather small and can be problematic at times with larger hands. For example, when pressing the right side of the d-pad, you can press the soft key or back button by mistake. The numeric keypad is also cramped and not nearly as large and user-friendly as the one found on the LG enV3. During our testing we had continual misdials when using the Intensity, which became annoying over time, so people with larger fingers should stay clear of this one. Located on the sides are the volume rocker, 2.5mm headset jack, charger / data port, speakerphone and camera button. Pealing off the battery cover will allow access to the microSDHC memory card slot with 16GB support, and the 1.3MP camera is on the back.

The sliding QWERTY keyboard has 4 rows, similar to the Rogue, but the d-pad arrows on the right are not individual keys and share real estate with the “L, N, M, and period” keys. All of the buttons are also slightly curved and angled, instead of being perfectly square. When typing messages, we found the QWERTY keyboard on the Samsung Intensity U450 to be more comfortable than the one found on the Rival and Alias 2, but still not a roomy as the enV3.

To me it did not feel even close to cheap to the Rival. Sliding feels strong and solid and don't believe it ll break easy. At $50 don't expect something quite as solid as the enV3 (which is sold at $130). Also it does not have EVDO much like the Sway. For the value I expect to sell quite a few of these. Already sold our first shipment of 3.

It had good signal reception, as it showed 2-3 bars and didn't drop any calls in our area. The call/voice quality (through the earpiece speaker) wasn't as good and natural sounding as on other phones (enV3, Alias 2).

Go to contacts, scroll down to 5. Speed Dial and then fill in the phone number in the Go To section and it will add it to the list.

I am having a difficult time finding a bluetooth earpiece that will work static free with this phone. All of the earpieces that I have tried will work great on my LG EnV2, but not without static on the Intensity. What bluetooth should I use with this phone?

I like the phone

I"ve had the phone for a few months now. To me it feels solid, reception and call quality is good. I just wanted a basic phone with a qwerty keyboard and this is perfect. I have relatively small hands so the keys aren't an issue - if you have large hands/fingers I could see where that might be a problem. No problems with my blue tooth ear piece or setting up the speed dials etc. I'm extremely happy with this phone.

Does anyone know why this phone decides to light up on its own in the middle of the night on its own. It always happens around 4:30 in the morning and wakes us up

I have the Intensity II and mine also lights up in the middle of the night, at 3:03am. It's weird that no one is touching the phone and it's lighting up on its own. Does anyone know why this happens?

Mine lights up when receiving a message or I'm charging it. That's weird that yours lights up unprompted by anything. Are you sure it's not an alarm or calendar appointment or something? Does it also vibrate or make any sound?

I have the intensity. I hate it. I drop it alot but not badly. Only a little less than a foot off the ground. The calls are bad quality and my texts don't always send. It looses battery by the end of the day. Sometimes before dinner. The camera is bad. Bad sound recording quality. The charger doesn't work unless I hold it.

My son and I have been using this phone for well over a year on the Alltel network. He decided to go on a plan with his girlfriend and got a different phone. Alltel's plan for one was a bit too much for me as all I need to do is text and talk. I went to Wally_World and got a Straight Talk phone tha is working on the AT@T network. Big mistake. The phone has vastly inferior reception where I live. Verizon phones do not pick up that great here either. I will be going back to Alltel and my Samsung U450 next month. I love the phone. It has never failed me and the keyboard is perfect with all the keys where one would expect them to be. I HAVE had to turn my phone off a couple of times over the past year +, to get it to reset, but this new phone that I have got now that is working with ATT&T has already hung up on me three times in less than a week. I can't wait to get hooked back up with Alltel and get my U450 back on line. :)

Sounds like you broke the phone. Quit dropping it. You can't blame the phone for your clumsiness.
