MySettings - Do you often change different frequently used system settings? Then, MySettings is for you.
MySettings is a beautiful tool that allows you quickly enable or disable different settings (ringer mode, brightness, gps, wi-fi, bluetooth, unlock pattern, autorotate, screen timeout, auto sync etc)
Dazzle Configurable Switcher - The ultimate switcher bar for your phone. Choose from 4 widget sizes, and choose which controls it shows: ringer, sync, WiFi, BT, GPS, airplane, or brightness with min/max/preset (and auto toggle on some phones). Now with both one-touch and popup controls. WIDGET, NOT AN APP: you have to install it on your home page
Test Card - A very simple screen test card for Android. Designed to allow you to view the structures of pixels under magnification. On many phones this will be totally uninteresting; on some, notably AMOLED displays, it may be more useful. Please read the help for more info
Touch Test - Shows display parameters, multiple touch points, and trails to let you see how linear your touchpanel is. Different hardware supports 1, 2, or more fingers -- see which yours is. Note Android before 2.0 supported only single touch. Please see the help for more info
LCDDensity for Root - Application for changing LCD density settings on your Android phone almost on the fly. Smaller number means larger resolution.
Changes will not survive reboot (so if you have wrong settings, pull out battery or restart device and you are back to old settings)
DashBoard - (formerly CarMode) is an alternative to Car Home. Basically what it does is it shows you huge buttons to important apps that you might use when driving a vehicle with less distraction than manually waking your phone, opening the app drawer, etc. Unlike Car Home, this app will give you more flexibility and more settings to poke around with
Sound Manager - Exposes the sound & volume controls. Quick way to change ringmode, vibration, or mute (w/shortcuts). For each volume setting you can set schedules to automatically change volumes at set times. You can specify which days of the week each change applies to
