Picture this: you try to update your favorite apps and every attempt ends with an error. The screen says update failed and you see a message about the app store not trusting the connection. The culprit is often a simple mismatch between your phone’s date and time and reality. When the clock is off, secure connections fail because servers check the SSL certificates against your device time. That means the apps you rely on may not update until the clock cooperates. The problem can hit both Android and iOS users, and it usually shows up as update errors or a message like “cannot verify update.” The fix is usually quick and straightforward. In minutes you can restore proper time and get updates flowing again. Most people solve this by correcting date and time settings on their smartphone.
Why date and time matter for updates goes beyond a clock. When you download an app, the store uses HTTPS with certificates that have specific validity windows. If your device time is far off, those certificates look expired or not yet valid, and the connection is blocked. This is not about your memory or your network simply being slow. It is about trust. Once the clock lines up with real time, the certificates validate and updates can proceed. Common triggers include airplane mode glitches that linger after a trip, the wrong time zone, auto-sync turned off, or a network change that resets the device clock. You might notice messages like update failed or cannot verify update. The fix works in most cases, so it is worth a quick check. Does your clock show the correct time now? If not, you are in the right place to fix it.
Quick Fixes for Android Phones
If you own an Android device, follow these steps in order. They are designed to be easy and fast, and most steps take just a minute or two.
- Check the basics first
- Open Settings and look for Date and time options. You want the system clock to be in step with reality. A slow or incorrect clock breaks certificates. Start by checking your internet connection; a weak or unstable connection can also cause update checks to stall.
- Turn on network time
- Settings > System > Date & time. Enable Use network-provided time. This lets your carrier or network set the clock automatically. Then give the phone a moment to sync and try the update again.
- If auto time is not reliable, set it manually
- Turn off network time and manually set the date, time, and time zone. Pick the correct region and city for the time zone. Save the changes and restart if needed. Then try the app update again.
- Restart and test
- A quick reboot can finish the time fix and clear minor glitches. After reboot, open the app store and start the update again.
- Clear Google Play cache
- Settings > Apps > Google Play Store > Storage > Clear cache. This refreshes the store’s data, which can help after a time fix. Open Google Play and retry the update.
- Brand variations
- On Samsung or other brands, paths may vary a little. The core idea remains the same: verify time settings, then clear cache if needed. If updates still stall, confirm you are connected to a reliable Wi Fi or mobile data network.
Enable Auto Date and Time on Android
This is the easiest fix when it works. Swipe down from the top of the screen to open Quick Settings, tap the gear icon to open Settings, and search for “date time.” Turn on automatic options for both date and time. Networks usually set the clock accurately, so this keeps things in sync. If the option is grayed out, check your SIM card status or whether you are connected to Wi Fi. A missing SIM or poor network can prevent auto time from working. Once auto time is back, retry the app updates.
Set Date, Time, and Time Zone Manually
If auto time remains unavailable, you can set everything by hand. Disable auto time first, then set the correct region, city, and time. Ensure the time zone matches your current location. After saving these settings, reboot the device and attempt the updates again. A fresh manual setup often fixes stubborn cases where the clock drifts.
Step-by-step for iPhone users
iPhone owners can fix date and time mismatches with a similar approach, tailored to iOS. The steps are direct and typically quick. Start with automatic time, then move to manual if needed. After you adjust the clock, restart the iPhone and try App Store updates again. If a VPN is in use, it can interfere with time detection or purchases, so disable it briefly while testing. As with Android, the goal is to restore a trustworthy time signal so the store can verify certificates.
Turn On Automatic Time for iPhone
- Open Settings
- Tap General
- Choose Date & Time
- Turn on Set Automatically
If the toggle is missing or unavailable, try toggling Airplane Mode on and off. This can force iOS to refresh network settings and pull the correct time again. After enabling automatic time, attempt the App Store update. A successful update confirms the clock is aligned.
Adjust Time Zone and Date Manually on iPhone
If automatic time does not work, disable Set Automatically. Tap Time Zone and choose the correct city. Then adjust the date and time to match real time. Return to the home screen and try the App Store update again. A quick reboot after manual adjustments can help ensure the new settings take effect.
What to Try If App Updates Still Fail
If the clock is correct and updates still fail, there are a few more steps you can take. Start with the simplest fixes and work your way up.
- Free up storage space. A full device can stall updates or affect app behavior. Delete or offload unused apps and clear cache where possible.
- Check the network. Run a speed test or try a different network. A slow or unstable connection can create a misleading update error.
- Sign out and sign back in. On Android, sign out of Google Play and sign back in. On iPhone, sign out of the App Store and sign back in.
- Update the operating system. A pending OS update can affect app compatibility and store behavior. Install any available updates.
- Reset network settings. This clears Wi Fi passwords and other network data, which can fix miscommunication with time servers.
- Consider a factory reset as a last resort. Back up data first. A reset can fix stubborn time or certificate problems that simple settings changes cannot.
- Malware is rare, but it can impact system behavior. If you suspect it, run a reputable security check and remove any threats.
