Back in the old days when smart-phones are not the rage yet, the phones we have usually have those keypad lock mechanism. It help to prevent accidental press of buttons on the phone when we tuck our phones into pockets or bags etc. Then when we want to use the phone again, we unlock the keypad lock.
Fast forward to current smart-phones mania. Android has a similar keypad lock mechanism built in. When you do not use yours for a while, the screen goes off and then when you want to use again, the screen turns on and the keypad locked. Depending on which Android phone manufacturer you bought from, you can do some settings change to control this behavoir to a certain extent but it may not be entirely satisfactory.
The complain is the number of swipes needed to unlock the keypad can be a lot if you multiply the number of times you do that each day x 365 days. This app helps to do away with those time-wasting swipes to unlock the keypad. It uses a simple idea. If the screen is turn off, then the keypad is locked automatically. When you want to use and the screen turn on, the keypad is unlocked automatically. To start this behavoir, tap "Start". To stop this behavoir, tap "Stop". It is that simple.
Please note this is a software approach so if there are manufacturer proprietary settings control or third party apps like Screen Lock with password etc feature, it cannot override. You can turn that off and then this app will work as advertised. It works purely based on Google provided Android SDK.
The application support English, Simplified Chinese, Traditional Chinese display.
