Due to being one of the less common screen resolutions, applications and modifications tailored specifically for WQVGA (around 400 by 240 pixels) devices are hard to find. In addition, the lowered screen real estate makes the transfer of applications designed for devices with larger screens look messy and non-functional.
XDA member Rugal has recently created one of the only resolution-specific dialer alternatives for WQVGA devices such as the Samsung Omnia i900. The Mini-Lite Dialer is a 2G phone canvas designed to increase the finger-friendliness of your phone’s call-making functionality without removing popular features.
The phone canvas is available to download and try in the dialer thread. Although the developer only tested the modification on the Omnia i900, initial reports from other members are positive._________
