Cannot exit app on Blu Zoey Smart

[dilworks]

Congratulations for the great app for our KaiOS phones! I'm a fan of OpenStreetMap, and I found that KaiMap is the only OSM-enabled map app that actually WORKS for me without crashing/hanging/softlocking.

Except that... I can't find how to exit it on my specific KaiOS handset (a Blu Zoey Smart, running KaiOS 2.5.1), and this is because how Blu actually designed the keyboard mappings on this (terrible) phone: the phone lacks a Backspace key, and while it has an EndCall key, it's actually mapped to Backspace! And a quick look at the code means that there is no way to exit KaiMap on such "nonstandard" keypads, as the app expects an EndCall key event which this phone cannot provide, ever.

I suggest either making the exit key remappable, or allow Backspace to prompt for exit when on the map view.
