How do I keep my screen still during a call?

Some Android phones, like the Motorola Droid and Droid 2, have especially sensitive touch screens or faulty proximity sensors, which keep the screen active during phone calls. This can be a problem as the nearness and movement of the user’s face inadvertently activates soft buttons, unintentionally launching other apps or putting the call on mute or speaker.

Two free Android apps, Quick Lock and Lock Now Free, enable users to manually freeze the screen immediately after placing or answering calls. Both are fairly accessible and easy to use.

Quick Lock

Quick Lock by Sakura Soft is best for phones with physical End Call buttons because the accessibility option that allows users to end calls with the power button needs to be turned off. The app is free and available from Android Market. The first step is to find the app and install it to the phone. Then the setup begins:

Setting up Quick Lock

1. Use Settings to uncheck Power Button Ends Calls by doing the following:
a. From the Home screen, open Settings.
b. Arrow to and press d-pad OK on Accessibility.
c. Arrow to Power Button Ends Calls. If it is checked, press d-pad OK to uncheck it.
d. Return to the Home screen by pressing Back several times or Home once.
2. Open Quick Lock from the Home screen. When the app opens, Talkback announces, "Select lock mode," offering 3 options: Sleep, No Sleep, and Cancel.
3. Arrow to and press d-pad OK on Sleep. Talkback does not announce that the item is checked.
4. Return to the Home screen by pressing Back several times or Home once.

Using Quick Lock

1. Make or receive a call by doing one of the following:
a. Dial and press send, listening for the phone to ring.
b. Answer the phone with the unlock gesture, listening for the line to open.
2. Lock the screen immediately by pressing the power button twice.
3. If desired, access the screen again during a call by pressing the power button twice, then swiping in the usual place to unlock.

Lock Now Free

Options are the Search and Call keys and the Status bar. The application appears to do more, but documentation is sketchy .
