BlackBerry smartphone Input Language changes automatically

In some cases, the Input Language on the BlackBerry smartphone may change without the BlackBerry smartphone user manually making the change from within the Options application.

As designed, the Input Language can be changed when the keypad shortcut ALT + Enter is used from either the Home screen or from within an application.

Follow the steps below to remove the Input Language shortcut and change the language.

For BlackBerry Device Software 4.1 to 5.0:

Go to Options > Language (or Options > Language and Text Input). Set Use Input Language Shortcut to No. Change the Input Language back to the language you had originally set.

OR

Press ALT + Enter. Select the language you wish to use. When prompted, choose Do not allow this shortcut. The ALT + Enter shortcut key is then disabled.

For BlackBerry Device Software 6:

Go to Options > Typing and Input > Language. From the Language Switcher section, set the Shortcut Keys option to None. Change the Input Language to the language you had originally set.

OR

Press ALT + Enter. Select the language you wish to use. When prompted, choose Do not allow this shortcut. The ALT + Enter shortcut key is then disabled.
