The app should pickup any Bluetooth device in the area. are you seeing any bluetooth devices showing up on the screen? If not it may be the app, or you have a pre Bluetooth battery. It should show Bluetooth on the side of the battery.
Android phone, correct app, Location & Bluetooth on. It should be simple but somethings not right. I’ve even tried a diff Android phone. Great customer service from amped. Just contacted them yesterday and already willing to ship out a new battery today
