Symptoms
- App closes itself right after opening
- App freezes then disappears back to the home screen
- Crashes only happen inside one specific app
- Error message about the app 'stopping'
Likely causes
- CommonOutdated app version with a known bugDevelopers push fixes constantly; an old build may be broken on your OS version.
- CommonCorrupted cache or app dataCached files can get damaged over time and confuse the app on launch.
- PossiblePhone OS is out of date for the appNewer apps sometimes require an OS version your phone hasn't installed yet.
- PossibleLow storage spaceApps need free space to write temporary files and can crash without it.
- Less commonBug in the app itselfSometimes a bad update ships to everyone, not just you.
What to do
- Force-close the app completely and reopen it once to rule out a one-time glitch.
- Check the app store for a pending update and install it.
- Go to the app's settings (Android: Settings > Apps > [app] > Storage) and clear the cache, not the data.
- Restart your phone, since this clears temporary memory issues.
- Check available storage; free up space if you're under 1–2 GB.
- If it still crashes, uninstall and reinstall the app (note this may sign you out).
- Check if your phone's OS is up to date and install any pending update.
When to call a pro
If every app crashes constantly even after a restart, that points to a deeper software or hardware issue worth having a phone repair shop check.
