Check temperature sensor or temperature phone battery temperature in Celsius and Fahrenheit.
Note: The phone thermometer can measure the temperature of your phone around, but few phone has a temperature sensor, the temperature of all the majority of mobile phone display is the phone''s internal temperature. If the phone is in standby mode for a long time, the temperature display will be close to the temperature of the phone around. Therefore, the only way to accurately read the ambient temperature is to your phone is in standby mode for at least one hour after you activate the phone, then immediately open the software. The disadvantage of this limitation is not the software, but this way you can make relatively accurate temperature reading.
