How to Fix Google Play Store Error 501
What error 501 means
Error 501 is a Google Play Store install error that kills app downloads and updates mid-process. You tap Update or Install, things look like they are moving, and then the pop-up lands: the app could not be downloaded due to an error (501). Unlike error 492, which is mostly a storage problem, or error 495, which is mostly a network problem, 501 sits in the middle of the download pipeline — the pieces arrive, but they cannot be assembled and installed cleanly.
It shows up most often during updates rather than first-time installs. The reason is that updates reuse the app’s existing install session: a stale or half-written update file on the phone poisons every retry, so the same app keeps failing while other apps install fine. This is also why the most reliable fix is boring but effective — wipe the Play Store’s cache and data so those poisoned partial files are gone, and the next update attempt starts from a clean session.
The good news is that 501 is one of the more fixable Play Store errors. Because the fault lives in temporary cached data, account state, or device settings rather than hardware, the standard repair sequence — restart, clear the store’s cache and data, clear the Play Services and Download Manager cache, verify date and time, and rebuild the Google account link — resolves it for most people in about fifteen minutes without losing any personal data.
Common causes
- Corrupted Play Store cache or data: broken temporary records and half-written update files can block new downloads before the install completes.
- Stale Google Play Services or Download Manager cache: these handle the download pipeline in the background, so bad data there surfaces as store errors even when the store app looks fine.
- Nearly full storage: a phone with less than about 1 GB free cannot write install files, and the store may report the failure as 501 rather than a clear storage warning.
- Wrong date, time, or time zone: an incorrect system clock breaks the security certificates the Play Store uses to verify downloads, killing the install.
- Broken Google account token: the download authorization between your phone and Google’s servers has gone stale, so every install attempt is refused — common when 501 hits all apps at once.
How to fix error 501 — step by step
Work through these fixes in order. Most people are fixed by step 2.
- Restart your phone. Press and hold the Power button (or swipe down from the top of the screen and tap the power icon), then tap Restart. A reboot clears hung download sessions and half-written install files that can keep error 501 firing on every update attempt. Once the phone is back on, open the Play Store and retry the download — it is quick, harmless, and fixes a small share of 501 cases outright.
- Clear the Google Play Store’s cache and data. Open Settings, then go to Apps (or Apps & notifications), then See all apps. Tap Google Play Store, then Storage & cache. Tap Clear cache first, then Clear storage (or Clear data) and confirm. This wipes the corrupted temporary records and partial download files behind error 501 without touching your installed apps, photos, or personal data. Reopen the Play Store, accept the terms again, and retry the download.
- Clear the Google Play Services and Download Manager cache. In Settings > Apps > See all apps, find Google Play Services, tap Storage & cache, and tap Clear cache — clear only the cache, not all data, since Play Services holds sync state other Google apps rely on. Do the same for Download Manager (tap the three-dot menu and choose Show system if it isn’t listed). These handle the download pipeline behind the scenes, so stale state in either can reproduce error 501 even after the store’s own data is wiped. Restart the phone and try again.
- Check your date, time, and storage. Go to Settings > System > Date & time and make sure Set time automatically and Set time zone automatically are both on — wrong system time breaks the certificates the Play Store uses, which can surface as error 501. Then open Settings > Storage and confirm at least 1 GB is free; delete unused apps, old downloads, and cached videos if needed.
- Remove and re-add your Google account. This is the targeted fix when error 501 affects every download: the account token your phone uses to talk to Google’s download servers has gone stale. Go to Settings > Passwords & accounts, tap your Google account, then Remove account. Restart the phone, return to Settings > Passwords & accounts, tap Add account > Google, and sign back in with the same account. Rebuilding the account link clears the server-side glitches that cache clearing alone cannot reach.
- Roll the Play Store back and update everything. In Settings > Apps > See all apps, tap Google Play Store, tap the three-dot menu, and choose Uninstall updates, which rolls the store back to its factory version so it can update itself cleanly. Then go to Settings > System > System update and install any pending OS patches. Restart the phone, reopen the Play Store, let it finish updating itself, and retry the failed app. A factory reset is the last resort — back up everything first.
Did this fix it? Quick checklist
- The app downloads or updates without the 501 pop-up
- Other pending updates install normally too
- The Play Store opens, browses, and searches normally
- Downloads complete over both Wi-Fi and mobile data
If error 501 still appears after all six steps, double-check that you know the password for the Google account on the phone, then remove and re-add the account one more time — the first attempt sometimes fails to rebuild the token if the network was flaky. As a final measure, back up your data and consider a factory reset (Settings > System > Reset options > Erase all data).
Frequently asked questions
What does Google Play Store error 501 mean?
Error 501 means the Play Store started an app download or update but could not finish installing it — the attempt dies with a “could not be downloaded” 501 pop-up. It most often hits during app updates rather than first installs, and is usually caused by corrupted Play Store cache, stale Google Play Services or Download Manager data, a nearly full device, wrong system time, or a broken account token.
How is error 501 different from error 492 or 495?
Error 501, 492, and 495 all belong to the same family of install failures, but they point at slightly different faults. Error 492 is a storage-side install failure — the phone cannot write the install files. Error 495 is a network or sync failure — the phone cannot reach Google’s servers. Error 501 is a download-pipeline failure that most often strikes during updates: the pieces download but cannot be assembled and installed, usually because of corrupted store or services cache.
Why does error 501 appear when I update an app but not when I install a new one?
Updates reuse the app’s existing install session, so a stale or partially written update file can poison every retry — a fresh install gets a clean session and may work. Clearing the Play Store’s cache and data removes those stale update files, which is why that step fixes most update-only 501 cases. If it doesn’t, remove and re-add your Google account to rebuild the download authorization.
Can wrong date and time cause error 501?
Yes. If your phone’s clock or time zone is wrong, the security certificates the Play Store uses to verify downloads will not validate, and the install fails — sometimes reported as error 501. Open Settings > System > Date & time and turn on Set time automatically and Set time zone automatically, restart the phone, and retry the download.
What if error 501 keeps coming back after every fix?
Recurring error 501 usually means there is an ongoing problem with your Google account authorization or a persistently full device. Remove and re-add your Google account again, keep at least 1 GB of free storage, and uninstall the Play Store’s updates so it rebuilds itself from the factory version. If the error survives all of that, back up your data and factory reset — it is the most reliable permanent fix.
