The testers over at our review partner Digital Trends published a review of the Samsung Glyde SCH-u940. The touch screen of the Glyde seems to be a problem.

Quote from the review: "The Samsung Glyde has a lot of potential, with a smooth-sliding full-size QWERTY keyboard and a 2.8-inch touchscreen, as well as extras like assisted GPS, Bluetooth, haptic feedback, and a 2-megapixel camera. It even looks like a smaller version of one of its main competitors, the LG Voyager, though it lacks the former's mobile TV capability. Unfortunately, the Glyde's main input method - the touchscreen - doesn't work well enough for us to recommend the phone."
