Apps crashing, wifi disconnecting, and settings stopping

This guide prioritizes specific fixes for app crashes, wifi drops, and settings errors after Samsung updates, avoiding generic advice to save your time.

Why apps keep crashing after Android update on Samsung

Apps crashing after an Android update on Samsung phones happen mainly because the new system version introduces changes that some apps don’t support yet.

One key factor is incompatible apps that need updates to work with the new Android version or Samsung’s One UI changes.

Another cause is corrupted cache or app data carried over from before the update, which conflicts with the updated system environment.

Google Play Store updates or Google Play Services updates may also lag behind and cause app instability. Before you commit to anything, it is worth looking at apps won't open since macos update.

Sometimes, the update changes permissions or background operation rules, which older apps fail to handle.

Another cause of app crashes after an update can be residual files left over from previous app versions that the update process doesn't clean properly. These files may conflict with the new app binaries or Android framework components, leading to crashes. Checking for unusually large cache sizes or storage use by affected apps can help identify this issue.

Sometimes, system updates introduce new security features or stricter background activity restrictions that older apps are not designed to handle. For example, apps relying on persistent background services may crash if those services are abruptly terminated. Monitoring app crash logs via developer options or using third-party tools can provide clues on permissions or API usage causing crashes.

• Incompatible apps – apps not updated for the Android version
• Corrupted cache – old temporary files causing conflict
• App data corruption – settings or files stored by the app
• Play Store or Services update delays
• Changed permissions or background limits

Clear app cache and data to fix crashing apps

Start here: clearing an app's cache removes temporary files that can conflict with a new Android build. This is the least intrusive fix and should be tried first because it keeps your account sign‑in and most app settings intact. Open the app's Storage page and tap Clear Cache; observe the app for a few minutes and try the action that previously caused the crash. If crashes stop, you are done.

If clearing cache does not help, the next step is to clear app data (also shown as Clear Storage). This resets the app to a fresh state and will erase locally stored preferences, downloaded content held only inside the app, and any unsynced progress. Back up anything you cannot recreate or that is not synced to the cloud before you clear data. After clearing data, sign back in and check functionality; many persistent crashes caused by corrupted local data are resolved by this action.

Only after cache and data have been tried for the crashing app should you move on to broader measures: update the app and Google Play Services, uninstall and reinstall the app, reset app preferences, or check battery optimization and background restrictions. Reserve factory reset as the final measure — recommended only when multiple core apps still crash, Wi‑Fi and settings behave incorrectly after you have exhausted all targeted fixes and backups of your data are complete. A factory reset wipes the device to its original state; perform it only when you cannot restore stable operation by clearing cache/data, reinstalling apps, or updating system and app software. We cover solving windows 10 errors in its own article.

1. Open Settings > Apps.
2. Find the crashing app and tap it.
3. Tap Storage, then Clear Cache.
4. If crashes continue, tap Clear Data (or Clear Storage) after backing up any unsynced content.
5. If multiple apps crash, clear cache/data for Google Play Services and Google Play Store, then update those apps.
6. If problems persist, reinstall the app, check battery optimization, then consider a factory reset only as a last resort after full backups.

Update apps and Google Play Services after the Android update

Apps need to be compatible with the latest Android version and Samsung’s One UI. Without updates, they may crash or misbehave.

Google Play Services is critical: it manages many app functions and security checks. An outdated version often causes crashes.

Updating apps from the Play Store refreshes compatibility and bug fixes released by developers post-update. We go through phone keeps rebooting android step by step elsewhere on the site.

Sometimes, the Play Store itself needs an update to display and install app updates correctly.

Make sure your phone is connected to a stable WiFi with enough battery or charging to avoid interruptions.

1. Open the Google Play Store app.
2. Tap your profile icon, then Manage apps & device.
3. Tap Update all to refresh all installed apps.
4. If available, update Google Play Services via the same page.
5. Restart your phone after updates to finalize changes.

Fix Android phone not connecting to WiFi after update

Wifi problems after a Samsung update often come from changed network settings or incompatible drivers in the update. People in this spot often ask about apps greyed out after family share as well.

The first fix is to toggle Airplane mode on and off to reset the wireless radios.

Resetting network settings wipes saved WiFi passwords and resets all network preferences, resolving many connectivity issues.

If you face persistent drops or no connection, deleting the specific WiFi network and reconnecting is useful. We go through deleting files on android step by step elsewhere on the site.

Ensure your router firmware is up to date; sometimes the phone update exposes router compatibility bugs.

Another troubleshooting step for WiFi issues is to check for conflicting apps that may be interfering with network connectivity, such as VPNs or security software. Booting into safe mode temporarily disables these apps, helping isolate the cause.

If toggling settings and resetting network preferences fail, manually setting the DNS servers (e.g., Google DNS 8.8.8.8 and 8.8.4.4) in the WiFi network properties can sometimes resolve connectivity problems caused by DNS conflicts introduced after an update. For the detail, see our notes on how to transfer data from android.

In rare cases, the Android update could cause incompatibility with certain WiFi frequency bands or modes used by your router. Switching the router to use a different band (2.4 GHz or 5 GHz) or changing security protocols (WPA2 vs WPA3) might restore connection stability.

1. Toggle Airplane mode on, wait 10 seconds, then off.
2. Go to Settings > General management > Reset > Reset network settings.
3. Re-enter your WiFi password after reset.
4. Forget and reconnect to your WiFi network.
5. Restart your router if issues continue.

Fix Android settings keeps stopping after Samsung update

When the Settings app crashes or shows “keeps stopping,” it’s usually due to corrupted app data or cache from the system update process.

Clearing cache and data for the Settings app can restore stability, like with third-party apps.

A system update can also break the cache partition on the phone, requiring a cache partition wipe from recovery mode.

If errors persist, booting into safe mode can confirm whether a third-party app is interfering.

A factory reset is a last resort if the Settings app remains unstable after these steps.

1. Go to Settings > Apps > Settings app.
2. Clear cache first, then data if needed.
3. Power off the phone.
4. Enter recovery mode (usually volume up + power button).
5. Select wipe cache partition, then reboot.
6. Boot into safe mode to test for third-party app conflicts.

When to factory reset your Samsung after Android update problems

Factory reset erases all data and restores the phone to a clean state. It solves stubborn issues that resist all other fixes.

Try all targeted fixes: clearing cache/data, updating apps, resetting network, safe mode boot, and wiping cache partition before reset.

Resetting is justified when apps keep crashing, wifi won’t connect, or settings crash despite all troubleshooting.

Back up important data before the reset since it deletes everything on internal storage.

After reset, install apps fresh rather than restoring a full backup to avoid reintroducing problems.

1. Back up photos, contacts, and documents externally.
2. Go to Settings > General management > Reset > Factory data reset.
3. Follow the prompts to erase and restart.
4. Set up your phone as new without restoring apps immediately.
5. Reinstall apps one by one, testing stability after each.
