Abstract
Described are methods and systems for estimating a baseline of a proximity sensor on an electronic device comprising: collecting proximity sensor data at the electronic device using the proximity sensor; collecting second data using a second source at the electronic device; obtaining a sample of the proximity sensor data at the electronic device when it is determined that no object is proximal to a first face of the electronic device based on the proximity sensor data and based on the second data; and approximating the baseline of the proximity sensor using the obtained sample.
