**** Please use this version rather than my original Lock Phone app ****
A simple application to lock your device with a single touch, and prevent you from wearing out your lock key.
Select the application from your application drawer and put it on your home screen.
This is a more light-weight version of my Lock Phone app, which has been developed using native Java for Android, rather than Tasker. This means it has a much smaller code footprint and thus requires less device memory to install, which will be important on some lower end devices with a smaller memory.
This has been tested on a Galaxy S3 phone and Galaxy Tab 10.1 running Android 4.0.
1) This app requires device administrator privilege to be able to lock the screen. After installing and the first time you run the app, you will be prompted to activate the lock screen admin. Please select "activate" (see screen shot).
2) There is a known problem with Android version 4.0 where the screen turns off and then on again if you have lock security set (e.g. PIN). The lock screen will be displayed when the screen switches back on, although this problem does seem intermittent.
3) To un-install the app, please revoke the device administrator setting for this app in Settings>Security>Device Administrators, and de-selecting the check box, which will prompt you to deactivate the lock screen admin. Please select "deactivate" (see screen shot) and then you will be able to un-install the app in the usual way.
New version includes:
Re-sizable 1x1 widget to lock phone.
Reduced the size of the application significantly, so that it takes up less memory when installed on your device.
