Other than to turn it off? The CallBar tweak, which replaces the traditional outgoing/incoming call screen with a bar at the top of the screen, works wonderfully in freeing up your screen while on the phone and still maintaining full access to in-call functions such as speaker, hold etc. However, when I have it turned on for outgoing calls, and I attempt to make a hands free call in my car, it kicks it off Bluetooth. Any idea how to fix this? Thanks.
