Methods and systems are described for proximity condition detection of a recovery from sensor proximity saturation caused by water immersion of a user device. The device transmits data at a first transmit power level using an antenna. In one system, a proximity condition checker determines that a first proximity sensor and a second proximity sensor are saturated in an unknown state after a power event where the saturation caused at least in part by the presence of water in proximity to the first proximity sensor and the second proximity sensor. The proximity condition checker determines that 1) both the first proximity sensor and the second proximity sensor are no longer saturated and 2) water is no longer in proximity to the first proximity sensor and the second proximity sensor. In response, the user device can transmit data at an increased second transmit power level using the antenna.
