Methods, systems, and devices for wireless communications are described. In some wireless communications networks, a device, such as a user equipment (UE), may be configured to detect a signal blockage affecting one or more antennas of the UE. The signal blockage may be associated with the position of a body, such as a user, relative to the one or more antennas of the UE, which may include how a user places their hand on or near the device during use. The position of the body may block one or more of the antennas of the UE, causing increased signal attenuation and decreased communications performance. The UE may be configured to signal, an indication based on detecting the signal blockage.
