Turn Your Old Android Phone/Tablet into the Ultimate Car GPS (for poweron with charger plugged in, see 12:36)

  • root your phone
  • install automateit pro

In Automateit pro

  • remove all rules and then add these new ones (NB program this with the power cable in, other wise one of the rules will have the system shutting down)
  1. Trigger: Battery level trigger below 15% Action: (composite action) 1. show notification (low battery) 2. screen brightness lower 3. [screen timeout 15 seconds - nb didn't do this]
  2. Trigger: Battery level below 20% Action: Shutdown device Delayed Execution: 15 minutes Rule name: Battery low shutdown
  3. Trigger: External Power Disconnected Action: shutdown device Delayed execution: 30 seconds Cancel Delayed Execution: Power connected Rule Name: Power disconnected shutdown
  4. Trigger: Screen off Action: Shutdown device Delayed execution: 1 minute Cancel delayed execution: (composite OR) 1. Screen on 2. Power Connected Rule Name: Screen off shutdown [NB This is because the above rule may sometimes fail to run: if you turn off the car whilst the phone is still booting]
  5. Trigger: (composite AND) 1. Device Boot 2. External power connected Action: Start Application (navigation / Torque) Rule name: torque start


Because Samsung can't do Fastboot the above method won't work for charger. See Automated power on with charging cable plugged for information for Samsung phones.
