Device without a `back` key

[sphh]

I use Warpinator on my Supernote e-ink notepad. This device does not have a Back key (the key left of the home key), hence it is not possible to return to the Available Devices page after clicking on a device.

Would it be possible to implement this feature somehow?

Thanks!

I'm pretty sure a back button or gesture should be a standard feature on all Android devices. Are you sure there is no gesture with the same effect (e.g. swipe from left edge)?

Not that I know of.

I also asked that clever AI and got the following answer:

On a Supernote e-ink device, there is no physical back button, and no built-in gesture-based back function like on smartphones or tablets.

How to Go Back on Supernote

Use the On-Screen Back Button (Top Left Corner)

In most apps (Notes, PDF, Settings, etc.), there’s a back arrow icon (←) in the top-left corner of the screen.
Tap it with your stylus or finger to go back.

📌 Example:
In Notes → Tap the arrow to return to the notebook list.
In PDF reader → Tap the arrow to return to the library or previous page.

So, all apps written for the Supernote have a soft back button.

Many apps I use on the phone also have a soft back button (but obviously not Warpinator for Android). Would it be feasible to include such a button?

Do you have a "Navigation Method" or something similar in your settings?

Can I choose "Gestures" or "Buttons"?

I double-checked and went through all the setting options: Nothing like this can be found.
