S4 built in sensors
After lil more than 1wk, I still discover a few new things about this amazing phone. Particularly the built in sensors. I read somewhere that S4 is the first smartphone with hygrometer to measure humidity. Cool.
But i have no idea that there's also the magnetometer is there also to measure magetic flux and field strength. I had fun moving it close to electronic equipments and an old phone case with magnetic clasp and see how the reading changes. testing near MRI is of course not rec.
Of course the barometer and thermometer are there too.
Between the two apps: weather signal and weather station, all these sensor readings can be accessed live... amazing.... forget about accessing s health to read sensor...
the only thing iphone got above s4 is the fingerprint reader. But i am quite certain that samsung won't let that by on their next iteration of the galaxy... Maybe they can figure out how to make a pulse reader and pulse oximeter sensor to build into the phone? I think built in body function sensors could be the next big things...
Btw, i am about to enclose my S4 into a watertight case. I imagine the barometer, thermometer and hygrometer will be a little less accurate .
