Android studio automatically open's documentation view

Strange, because I've not changed anything with AS from months and there was no such behavior before. There's solution:

Follow the simple steps to remove open Documentation by cursor move :

Android Studio -> File -> Setting -> Editor -> General

Right side of the screen go to Others :

• Uncheck checkBox show quick documentation of mouse move & Apply.

Preferences > Editor > General > CodeCompletion > uncheck Auto popup feature
