Hello!
I have a Android phone (SG S4mini) that i put on my car to work with TorqueOBD2 and GMaps apps.
I'm from Salvador, Bahia, Brasil and here is super very hot place. And so, to avoid start a fire on my veichle I remove the phone baterry, put a Buck Converter (12v for 3.7v) and connect on post ignition key, direct on baterry terminals (soldering)
All works perfect for a long time till now. But my only problem is: i need manually turn on the phone every time I turn on the car.
So, I need a way to automatic turn on my phone on when voltage (or current) is detect on baterry.
Just to be clear, is not boot when charging, because I do not use the charge port. Is BOOT WHEN VOLTAGE/CURRENT IS DETECTED ON BATERRY TERMINALS.
Plz I really need help!
