Welcome to Android Central! Android A to Z: What is ADB? | Android Central

What phone do you have? Does the Launcher keep stopping after a reboot? How about Safe Mode, which temporarily disables all 3rd party apps? On most Android devices, while powered on, press and hold Power until the Power Off menu appears. Press and hold the Power Off selection until the Safe Mode prompt appears. Tap OK.

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
