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.

Here is an APK with a back key on device page: warpinator-dev.zip
Alternatively you can apply this patch and build it yourself: 0001-Added-back-button-to-TransfersActivity.patch
I probably won't be adding this to regular releases as I don't think it looks very good and it is a device specific issue. The manufacturer should fix their Android build to provide a back gesture or software navigation buttons as it is a standard feature of all Android devices.

Many, many thanks for this apk.

I can see your point, even if Warpinator itself shows a Back button in the Settings page.

How about making it an option? Then the slick design will be the default and the back button for those of us, who use devices which excel in other areas?
