As expected, Samsung Galaxy S4 is getting Galaxy S5 applications like S Note, WatchOn, Calculator, Gear Fit Manager, Galaxy Gear Manager, S Health and S Translator now. Just install them like normal apk. Or wait for Galaxy S5 next month for the actual experience. By the way, you need KitKat TouchWiz ROM in order to use them. Therefore, they should work on Galaxy Note 3 too.
Samsung Galaxy S4 is loaded with lot of sensors. Ambient temperature and humidity level are 2 of them. Well, you can get these values with Comfort level feature in S Health application. Or in Temp-Humid test in FactoryKeystring application (How to test Galaxy S4 hardware functions?). But that require few clicks here and there. So XDA Developer, bala_gamer developed a nice Ambient Weather for Galaxy S4. You can get ambient temperature and humidity level straight from it.
