This is not uncommon and is due to the screen being activated by water drops. Using the Buttons App (a system app available on all our devices), configure one of the available hardware buttons to enable/disable screen touch. When riding in the rain lock the screen touch!

Inside the DMD2 app you will even find an option to automate this while you ride and you can even assign this function to one remote controller button.

By default when you plug our devices to a PC it will only charge the device.
If you want to access the device files from the PC you need to enable File Transfer in the device settings.

To do this you can check this video:

- Swipe down from the top of your screen
- Tap on the notification that says "Charging this device via USB"
- In the USB Preferences enable "Use USB for - File Transfer"

The only things that can continuously use internet data are online map layers and group ride. Here is an average data use reference:

Group Ride - around 10MB per hour (can be a bit more of less depending on the number of users in the group)
Satellite View - around 35MB per hour (depends on the map areas you load / zoom to )
Hill-shading Layer - around 40MB per hour (depends on the map areas you load / zoom to )

Everything else is user triggered, for example, downloading a map, which should be done only on a decent WIFI connection.

When DMD2 asks for the notification access permission, sometimes it can happen that you get a warning about it being a "restricted setting".

This is something you can easily solve by manually providing the "Allow restricted settings" permission.

This is done in Android Settings > Apps > Tap on DMD2 > Tap on "Force Close" > Tap on the 3 dots in the top right corner and select "Allow restricted settings".

In the video you can check step by step how to enabled restricted settings for DMD2.
