Execution Variant 1:
- The SQL Database that has to be changed, you find here:
/data/user/0/com.android.providers.settings/databases
- Install the SQL Database Editor on the Ascend P7
- open the Database settings.db with the SQL Database Editor; Before Backup this Database
- choose System
- search the entry hide_virtual_key
- change it from 0 to 1

Esto es lo mas fácil de todo sacado de XDA.
Un saludo.
