Blank screen for 5 seconds after call or app. ? ?

I have original Moto Droid.  After a call, or after using an app, my screen has nothing on it except the background (no icons) for 5 to 10 seconds.  Why?!

I have cleared the cache on all apps, rebooted the droid, still the problem.

Try closing unused applications that you have running in the background. 

From the home screen, touch the applications tab (located on the bottom of the screen). 

Touch Settings. 

Touch Applications.

Touch Running services. 

Touch the desired service.

Touch Stop.

Try deleting old messages  that you no longer need, to clear phone memory.  

If you are using a task manager or application manager, try setting it to high to close applications.

Dial *228 send and option 1.

Can you tell me what the following will do?  My phone is already activated:
