Can I use my Android phone as a TV remote (I don't have IR blaster and don't want to use one)? Is there any app to help me? An app is tracking my location without my knowledge, but I don't know which one it is. When the phone's screensaver comes on some app turns the GPS on and tracks me until I switch the screensaver off and start using the phone again. How can I see what apps have been accessing the GPS over the last 15 mins?
