1) Important to first note that some cords that allow you to connect your device to another device are only designed for charging. This means that they will not allow you to send data between devices using the cord, and only send power. If, for some reason, the steps below do not seam to work it may be due to the cable you are using.

The charging cables MARK37 provides with each Ghost Phone should not have this issue, however, we've learned to never say never these days as sometimes the unexpected and unplanned do happen.

2) Due to the default security settings of the GrapheneOS operating system, your device will not automatically grant file access once the phone is connected to another device. This is a good thing, for what should be obvious reasons. When your phone is connected to your laptop, for example, you will likely see something like this:

3) To grant access, first swipe down from the top of your phone so you can see all open notifications. You should see something like this:

Circled in red is what you're wanting to tap on to provide the appropriate access. Yours may say, "Charging this device via USB / Tap for more options."

4) The next screen is where you can determine what access you want to provide between the devices connected and which device you want to "run point" when managing the connection. This will look like the below:

You will not need to change the "USB controlled by" section. Leave "This device" selected.

You will want to tap on "File Transfer" below the "Use USB for" section. This will now grant access for your phone to move files to/from whatever you have it connected to.

5) Wait 5-15 seconds, and the prompt on your laptop or the other device you have your phone connected to will change, allowing you to now look at the files on the device and copy, edit, delete, move them as needed. If you are unclear where to go to open or see the files on your phone from your laptop, open the main file folder that shows you all your files. This should look like the 1st image shown above. On the left you'll see the phone as the specific make/model of the device or whatever name you may have given the device.
