Step-by-Step Fixes for Error Code 963
1. Clear Google Play Store Cache and Data
Go to Settings → Apps → Google Play Store → Storage → Clear Cache, then Clear Data. This removes corrupted temporary files that cause Error 963. After clearing, open Play Store and try installing the app again. This fix resolves the error in most cases.
2. Clear Google Play Services Cache
Go to Settings → Apps → Show System Apps → Google Play Services → Storage → Clear Cache. Play Services manages background app operations and a corrupted cache here can trigger Error 963. You cannot clear Play Services Data (only cache), which is normal behavior.
3. Free Up Device Storage
Error 963 sometimes appears when your device has less than 500MB of free storage. Go to Settings → Storage to check available space. Delete unused apps, move photos to cloud storage, or clear app caches to free up space before retrying the installation.
4. Remove and Re-add Google Account
Go to Settings → Accounts → Google → select your account → Remove Account. Restart your device, then add the account back. This refreshes your Google authentication tokens and often resolves persistent installation errors including Error 963.
5. Reset App Preferences
Go to Settings → Apps → More (three dots) → Reset App Preferences. This restores default settings for all apps without deleting any data. It fixes issues where disabled system apps are causing conflicts with Play Store installations.
Frequently Asked Questions
Will clearing Play Store data delete my apps?
No. Clearing Play Store cache and data only removes temporary files and login preferences. Your installed apps, purchases, and app data remain completely untouched. You will need to sign back into Play Store after clearing data, which takes less than a minute.
Does Error 963 affect all apps or just one?
If Error 963 appears on just one specific app, the issue may be with that app’s listing on Play Store — try waiting a few hours and retrying. If it affects multiple apps, the issue is with Play Store or Play Services on your device, and the cache-clearing steps above will fix it.
What if none of these fixes work?
If Error 963 persists after all steps, try a factory reset as a last resort (back up your data first). Alternatively, download the app’s APK directly from a trusted source like APKMirror. If the issue is only with one app, contact the app developer as the problem may be on their end.
