How can I test functioning of internal component (sensors, NFC, pedometer etc...) I recently dropped my LG G3 in water. I opened it and let it dry for a long time.

It now work properly but some components does not seems to work anymore. For example light sensor, proximity sensor or pedometer seems broken.

Is there any way, or application, to have a full check-up of my phone component to see what is going on ? I want to see if all component are still detected or not and if I can do anything about it.

Thanks in advance for your help.
