Abstract: Systems and methods for addressing an inadvertent decrease in transmission energy/power due to triggering a proximity sensor by a cover disposed on a computing device. In an embodiment, a cover sensor may be incorporated into the device. The cover sensor may be used to detect the presence of a cover on the device, as well as whether the cover is in an open or closed position. The output of the cover sensor may then be used to adjust a trigger/proximity threshold of the proximity sensor to account for the presence and position of the cover on the device. In this manner the device may avoid unnecessary power backoff caused by proximity of the cover, rather than proximity of the user. This improves the over the air (OTA) performance of the device, as well as the user experience.
