Mobile devices are gaining more advanced capabilities, and they are no longer only used for making a phone call.
One possible use for these devices is medical. Although there are already several applications that perform medical tasks, they still rely on basic non-specialized sensors like the microphone or the camera to work, making them inaccurate at times.
In the future, it could be possible that phones will include special hardware, such as oximeters for people who require special medical attention.
