Thumbs up [Q] Android MODIFY_PHONE_STATE & customTelephony APP

'Trying' to create a custom telephony app that will maintain focus on incoming calls.
Right now the native phone application ALWAYS takes focus on incoming calls.
How can I defeat this??

Does this have something to do with the inability to use MODIFY_PHONE_STATE permission?
