Review: Samsung DoubleTime for AT&T
For whatever reason (which I can't possibly fathom), the DT runs Android 2.2.2 Froyo. Not Android 4.0 Ice Cream Sandwich, not Android 2.3 Gingerbread, but the 18-month-old Android 2.2 platform. It is mostly stock, with only a few, easy-to-miss changes to some of the icons.
The DT has five home screens for customization, though the device supports up to six and as few as three. The main menu is a grid of apps and can be viewed in alphabetical order or in a customized order. It can't be viewed in list form or based on category.
The notification shade contains controls for the Wi-Fi, Bluetooth, GPS, and cellular radios, and can be used to lock the screen rotation.

The dock at the bottom of the home screen has four shortcuts in it. These can be changed, but it is a serious pain in the rear to do so.
As far as performance goes, the DT is a bit slow with respect to screen transitions, and reaction times to input. The lag was frustrating at times. The worst offender was the screen rotation issue. If you woke the device from sleep while it was being held sideways, for instance, and then rotated it to portrait orientation, the screen lagged big-time before changing to match how the phone was being held. Most of the lag I noticed occurred on the home screens. Apps ran OK for the most part.
