Informr score
The Samsung Intensity U450 currently has an Informr score of 6.3 out of 10. This score is based on our evaluation of 23 sources including reviews from users and the web's most trusted critics.

The Samsung Intensity is a horizontal slider with a distinctive Samsung look. Closed, the Intensity has an attractive, stylized fascia with red accents and large, waved keys on its alphanumeric keypad. The 2.1-inch 176 x 220 resolution display is adequate but not impressive.

When opened, the Intensity reveals a full QWERTY keypad that, while thoughtful in its key placement and design, lack the spaciousness one needs to really rock the keypad. Texting will require some focus, so as not to hit the wrong key, which diminishes the fun factor. However, to Samsung’s credit the keys are sculpted to help compensate for lack of real estate.

The Intensity comes with a 1.3MP camera, sub-par by today’s standards, Mobile Web 2.0, and an updated music player that allows you to choose different skins, including simple view, visualize, album art, and lyrics. Also included is a 2.5mm jack. Ideally you’ll want to listen to music with stereo headphones since the mono-speaker on the back of the phone isn’t very loud.

There have been many horizontal sliders that have come to market, and the Samsung Intensity clearly falls into the lower half in terms of features and overall quality. It’s a decent phone, but if you like this form factor there are sturdier phones with higher-end features available in the same price range.
