Android back button/gesture fails to exit the app
Category: Bugs Priority: P2 Severity: minor Area: android Reports: 3 Status: Open
Summary: Three Android users independently report that the system back button / back gesture does not behave correctly in Qaf. On an Infinix Smart 10 running Android 15 Go Edition the app "gets stuck" and still refuses to exit even after updating (screen recording provided). A second user reports that pressing the phone's back button does not exit the application and the on-screen keyboard stays open — pointing at back-press handling being swallowed while an input field has focus. A third (Farsi-speaking) user says the back button does not work when entering the app. Each instance is a minor annoyance, but it reproduces across very different devices, so it is likely a systematic back-navigation/predictive-back handling bug in the Android build rather than a device quirk.

On an Infinix Smart 10 running Android 15 Go Edition, the app does not exit properly and gets stuck. Abdellatif asked him to update and retry; after updating it still refused to exit on the back gesture, and the user sent a screen recording.

Sent a two-item bug report (subject "Bugs"); item 2 is this issue: the phone's back button does not exit the application and the keyboard remains open. (Item 1, the broken language setting, is tracked in language-setting-broken-android.md.)
- When I click the back button on the telephone, it does not exit the application, and the keyboard remains open.

Farsi user says the app is great but its back button does not work when entering the app; the same email also complains about irregular Persian font rendering (separate localization issue). No reply sent yet.
سلام خسته نباشید خدمت شما دوست عزیز، برنامه قاف عالیه اما فونت نامنظمی داره، و دکمه برگشتش هنگام وارد شدن به برنامه کار نمیکنه، اگه برطرف بشه خیلی عالی میشه با تشکر
Hello, well done to you dear friend. The Qaf app is great but it has an irregular font, and its back button does not work when entering the app. If this gets fixed it would be excellent. Thank you.
Details / repro
- Device confirmed affected: Infinix Smart 10, Android 15 Go Edition — app gets stuck, back gesture never exits, reproduced after an app update.
- Screen recording available:
Screen_Recording_20260812_201406.mp4, shared by FATEH SIRAJ via a OneDrive link in thread19fe7929b5c43882. - Mahmoud's report couples the failure with the keyboard staying open, suggesting back presses are consumed (or focus/IME state is mishandled) instead of dismissing the keyboard and then closing the activity.
- The Farsi report describes back not working "when entering the app", i.e. immediately on the entry screen.
- Worth checking: predictive back gesture handling on Android 13+ / Go Edition,
onBackPressed/OnBackPressedDispatcherinterception in the webview or navigation stack, and IME-focus interaction.
