Quick answer: Disable quit-on-go-back and handle NOTIFICATION_WM_GO_BACK_REQUEST yourself to open a menu or navigate, only quitting when appropriate.
Players swipe back expecting to pause and your Godot game just closes, losing progress. The default back behavior is to quit. Intercept the go-back request so you decide what back means in each screen.
How to fix it
1. Disable auto-quit on back
Turn off Application/Config/quit_on_go_back (or set it via code) so the engine no longer terminates automatically on the back action.
2. Handle the go-back notification
Override _notification and respond to NOTIFICATION_WM_GO_BACK_REQUEST by opening the pause menu or going up one screen instead of quitting.
3. Confirm before quitting at root
On the title screen, treat back as a confirm-to-quit prompt so an accidental swipe does not close the app outright.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every Godot error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
