Measures phone temperature in Celsius or Fahrenheit
Try ads free version of Phone Temperature - https://play.google.com/store/apps/details?id=com.triladroid.thermometer_pro
This app simply measures phone temperature in Celsius or Fahrenheit. Also it is possible to create a screenshot of the current phone temperature.
As a creator I use it to measure my phone temperature while running different apps. I just run app (for example some game) and then after some time check phone temperature and make a screenshot. Then I run another app and again after some time I take a screenshot of a phone temperature. It is always interesting for me to compare phone temperature while phone is engaged in different activities.
Also, the higher phone temperature, the faster phone will loose its battery charge. So it is useful to check phone temperature once in a while to ensure that there are no unwanted processes running in the background.
