Transfering an Incoming call to loudspeaker My Question is Can I transfer a call to loudspeaker or external speaker directly through app which the phone has when i get an incoming call

Thanks In Advance !!!
I haven't tested this, but Tasker should be able to do this. Create an Event "Phone Ringing" profile to perform the "Speakerphone" task (which you configure to turn the speakerphone on). This can be configured to only activate for certain callers if necessary.
