A bug is a problem or unexpected behavior that needs fixing. This can be an error, flaw, mistake, failure or fault. Use this tag for questions about particular bugs in Android or apps for Android, or workarounds for them; about the bug reporting process in general; or other user-oriented questions about bugs.
Questions in this tag must still be on-topic and constructive. Rants about bugs that annoy you aren't useful to anyone. Don't ask a question just to draw people's attention to a bug, or to demand a fix: only the developer of an app can fix a bug, or tell you when a fix will be available.
You can report bugs in Android itself to Google on the Android bug tracker. Don't use this link for bugs in manufacturers' customizations, nor for bugs in apps, which should be reported to the developer.
