Techniques are disclosed for detecting obstruction of a device's antenna(s) and then changing an operation of the device. A transmission time at which an antenna of an electronic device transmitted a signal can be identified. A response signal can be detected that was received at a receiver of the electronic device subsequent to the transmission time. Based on the response signal and on the transmission time, one or more response-signal characteristics can be determined. Based on the one or more response-signal characteristics, it can be determined that the antenna or that another antenna of the electronic device is at least partly blocked from emitting or receiving signals. In response to determining that the antenna is at least partly blocked, a changed type of operation can be identified, and the changed type of operation can be performed.
