Why don’t modern smartphones have thermometers?
People often wonder why smartphones do not come equipped with a digital thermometer despite being so technologically advanced. The answer to this is simple, the internal temperature of a smartphone makes it almost impossible to get an accurate external reading. Some smartphones already have internal thermometers that check the internal temperature of the device. Once the temperature crosses a certain threshold, it alarms the smartphone to reduce its functioning until the normal temperature is restored. For a smartphone to measure body temperature, it would require an external heat sensor that isn’t influenced by the heat emitted from the smartphone in any way. Since an external sensor would be an additional part of the device that would serve only one function, it is not included in the device. The design of the smartphone would also need to be changed to accommodate the sensor. Most companies do not see the payoff to be as big as the effort required to include a thermometer in a smartphone. Samsung did incorporate a thermometer with the Galaxy S4 and Note 3, but the idea did not take off among its buyers. Firstly, the instructions to use the thermometer were far too complicated, requiring to let the phone cool down entirely and making sure the heat from the hands does not affect the temperature reading. Even after following all the instructions, the temperature readings weren’t entirely accurate. Samsung dropped the idea in later iterations of the Note and Galaxy smartphones.

What about thermometer apps?
If you explore the Google Play Store, you will find several thermometer apps that claim to give accurate temperature readings. These apps aren’t reliable at all, since a smartphone does not have the hardware these apps could utilise to function as a thermometer. Our advice is to steer clear of such apps, as they may try to push malware under the guise of a thermometer app. There are certain digital thermometers that come with a smartphone app that syncs the reading from the external thermometer to your smartphone. You can record these temperature readings on your phone and monitor them over a period of time. The readings can also be instantly shared with your physician from your smartphone.
