Error 491 is one of those codes that tells you everything and nothing at the same time. Everything, because it's blunt: no downloads, no updates, nothing installs until it's gone. Nothing, because Google never published a plain-English definition of what 491 actually means. After years of reports, though, the pattern is clear — it's a broken download pipeline: corrupted cache in the Play Store, stale data in Google Play Services, or a Google account that's silently fallen out of sync. Work the six fixes below in order. The first three end it for the large majority of people; the rest are for the stubborn cases.
Quick Answer: Error 491 means downloads and updates can't complete. Clear the Google Play Store's cache and data at Settings → Apps → Google Play Store → Storage, then do the same for Google Play Services. If 491 comes back, remove and re-add your Google account under Settings → Passwords & accounts. Covers Android 10 through 14.

What Error 491 Means
Error 491 is one of the classic Play Store codes — old, persistent, and annoying. In practical terms it means the download process can't even start: every install and every update dies with the same error. Google never documented the code officially, but the failure pattern is well established across years of reports: corrupted cached data in the Play Store, stale data in Google Play Services (the engine behind downloads), or a Google account session that's gone stale on Google's servers.
Two things it is not: a hardware problem, or a banned account. It's purely a software-level download failure — which is actually good news, because software failures respond to software fixes. Starting below.
Fix 1: Restart Your Phone
Yes, the restart. I know — but a restart wipes the Play Store's in-memory state and kills any half-stuck download process, and a surprising number of 491 reports end right here:
- Hold the power button and tap Restart (or power off, count to ten, power back on).
- Once the phone is up, open the Play Store and try the download again.
Error gone? You're done. Still there? Then the restart did its job of ruling out the trivial cause, and Fix 2 is the real workhorse for this error.
Fix 2: Clear the Play Store's Cache and Data
This is the fix that actually kills 491. Corrupted temporary files are the leading cause of this error, and wiping them forces the store to rebuild everything from scratch. Your installed apps, app data, and purchases are not affected — this only touches the store app itself:
- Open Settings → Apps:
- Pixel: Settings → Apps → See all apps
- Samsung (One UI): Settings → Apps
- Xiaomi (HyperOS): Settings → Apps → Manage apps
- Find and tap Google Play Store.
- Tap Storage & cache (or just Storage).
- Tap Clear cache.
- Back on the app info screen, tap Force stop so the old process is fully dead.
- Reopen the Play Store and test a download.
Still seeing 491? Go back to the same Storage screen and tap Clear data (labeled "Clear storage" on some phones). Deeper version of the same fix — the store resets completely, and you'll just accept its terms again on next launch.
Fix 3: Clear Google Play Services Data
If the Play Store is clean and 491 survives, the corruption is one layer deeper. Google Play Services is the background engine handling downloads, authentication, and sync — when its data goes stale, the store can't complete anything no matter how clean it is:
- Go to Settings → Apps (same brand path as Fix 2).
- Find Google Play Services. Not in the list? Tap the three dots → Show system (or "Show system apps") to reveal it.
- Open Storage & cache.
- Tap Clear cache, then Clear data — on some phones this hides under Manage space → Clear all data.
- Go back, tap Force stop, confirm.
- While you're in the system apps, find Google Services Framework and clear its cache too.
- Restart the phone, open the Play Store, retry the download.
After this, the phone re-syncs quietly in the background for a minute or two. Give it that time before deciding whether 491 is gone.
Fix 4: Remove and Re-Add Your Google Account
Sometimes the account itself is the problem. Error 491 frequently traces back to a Google account that's silently fallen out of sync — Google's servers no longer recognize your phone's login session for downloads. Removing and re-adding it forces a fresh handshake. One warning first: this will pull synced contacts, calendar, and app data off the phone until you sign back in. Nothing is deleted from your Google account itself:
- Open Settings, then:
- Pixel / Samsung: Settings → Passwords & accounts (Samsung also has Accounts and backup → Manage accounts)
- Xiaomi (HyperOS): Settings → Additional settings → Accounts & sync — or Settings → Passwords & accounts
- Tap Google, then the account signed into the Play Store.
- Tap Remove account and confirm.
- Restart the phone. Don't skip this — it clears the stale session completely.
- Return to the same Accounts screen, tap Add account → Google, and sign back in (including 2-step verification if you use it).
- Open the Play Store and try the download.
Same account on a second device? Removing it here affects only this phone. Everything re-syncs the moment you sign back in.
Fix 5: Reset App Preferences
A softer reset for the stubborn cases. Resetting app preferences restores default permissions, re-enables disabled apps, and resets notification settings across the board — without deleting a single app or a byte of data. It clears the stuck download-related permissions that can feed 491:
- Open Settings → Apps (same paths as Fix 2).
- Tap the three-dot menu (top right).
- Choose Reset app preferences, then confirm with Reset.
- Restart and test the Play Store.
Nothing gets deleted — but any apps you'd disabled will wake back up, and notification settings return to defaults. Worth a quick once-over of your settings afterward.
Fix 6: Uninstall Play Store Updates
Occasionally the villain is a buggy Play Store update itself. Rolling the store back to the version that shipped with your phone — then letting it update cleanly — breaks that cycle:
- Go to Settings → Apps → Google Play Store.
- Tap the three-dot menu (top right) → Uninstall updates. Confirm.
- The store returns to its factory version. Open it — it normally re-updates itself in the background within a few hours.
- If it doesn't, just leave it open a few minutes; the self-update happens automatically.
- Once updated, retry your download.
While you're here, check free storage at Settings → Storage and keep at least 1 GB free. Low storage shows up as a contributing trigger in a lot of 491 reports, and clearing space costs nothing.
What If Nothing Works?
If all six fixes fail, you're into heavy territory. A factory reset is the most reliable permanent fix for recurring 491 — but it wipes the phone, so back up everything first (Google One backup, photos, important files), then Settings → System → Reset → Erase all data. Before that extreme, contact Google Play support from a computer: play.google.com → Help → Contact us, describe Error 491, and ask them to check for account-side throttling. Covers Android 10 through 14.

Frequently Asked Questions
What does Error 491 actually mean?
It means the Play Store can't complete app downloads or updates — the download process can't start at all. The usual causes: corrupted cache in the Play Store or Google Play Services, a Google account that's fallen out of sync, or low storage. It's a software-level issue: it can't damage your phone, and it doesn't affect your account standing.
Does clearing Play Store data delete my apps?
No. Clearing cache or data on the Play Store removes only the store's temporary files and local settings. Installed apps, app data, purchases, and photos are untouched. You'll accept the store terms again and possibly re-sign into your Google account — that's it.
Why does Error 491 keep coming back after I fix it?
Recurring 491 almost always means one of two things: an ongoing account sync problem, or storage that keeps filling back up. Do Fix 4 (remove and re-add the Google account) and keep at least 1 GB free at all times. A VPN routing through another country can also retrigger it — disconnect before downloading. If it still returns after all that, a factory reset is the most reliable permanent fix.
