Abstract: Methods and systems for improving signal reception and call quality by detecting a user's handedness of holding a mobile device during a call are described. Motion data of the mobile device can be collected by one or more motion sensor. A screen tilt angle can be determined and compared with a threshold tilt angle. A screen swivel angle can be determined and compared with a threshold swivel angle. A call handedness can be determined based on the screen swivel angle. One or more parameters of an antenna can be adjusted based on the call handedness.
