Are you calling people as a mistake by pressing a touch screen?
Do you have broken/hard pressing power button ? tired pressing on the power button after you have finished talking ?
Do you call people by mistake after you have finished talking on Bluetooth headset when the device stays in the pocket/bag?
Most unwanted calls are made by mistake after we hung up outgoing calls, Because there is no lock screen at the end of outgoing calls, by default !
This application will help you deal with at least one of the problems.
