It’s a pretty cool phone, but for some users, the power button is almost flush with the phone. This can make it difficult to say the least, especially at night. Fortunately, WidgetLocker is a useful app that lets you unlock your screen by pressing your volume buttons.
WidgetLocker is a $1.99 app available in the Android Market that provides a lot of functionality. Not only can you turn on your screen with the tap of a volume button, you can also add widgets and shortcuts to your lock screen as if it were one of the many home screens on your ThunderBolt. The WidgetLocker app also lets you add additional sliders to quickly launch your camera, Gmail or other apps.
All in all, a great app and a $2 steal. Especially if you have a ThunderBolt with a power button that is almost nonexistent. You can find it or buy it if you want.
