Quick answer
Android apps most often crash due to a full cache, an outdated app or system version, lack of memory, or an incompatible update. First clear the cache of the problematic app and update it, then check free space and update Android. If all apps crash, the problem is likely in the system or Google Play services.
How to recognize the problem
- The app closes by itself immediately after opening
- The screen freezes and then the app returns to the home screen
- The message "App has stopped" or "Application has stopped"
- The app runs slowly and occasionally restarts
- All apps crash after a system update
Most common causes
Corrupted app cache or data
Temporary app files can become corrupted and cause a crash on launch. Clearing the cache is safe and does not delete your accounts or content.
Outdated app or system version
An app built for a newer Android may crash on an older version. The same applies to an incompatible update of the app itself.
Lack of free memory
When storage is almost full, Android cannot provide space for the app to run and closes it. Check how much free space you have.
Google Play services problem
If all apps that depend on a Google account are crashing, the cause may be an update or cache of Google Play services.
Incompatible theme or system modification
Non-standard themes, launchers, or apps with special permissions can cause instability. Restore default settings.
Step-by-step fix
- 1
Clear the cache of the problematic app
Open
Settings > Apps > [app name] > Storage & cacheand tapClear cache. Do not chooseClear databecause that deletes accounts and content inside the app. Restart the app and check if it still crashes. - 2
Update the app in the Play Store
Open
Play Store > Profile > Manage apps & device > Updates availableand install all updates. If the app is already updated, check if a patch has been released in the meantime. - 3
Check free space
Go to
Settings > Storageand see how much is free. If it is less than 1 GB, delete unnecessary files or move photos to your computer. Android also needs space for temporary files. - 4
Update the Android system
Open
Settings > System > System update, and on some modelsSettings > Software update, and check for new versions. Install them and restart the phone. System updates often fix app crashes. - 5
Clear Google Play services cache
If many apps are crashing, open
Settings > Apps > Google Play services > Storage & cacheand tapClear cache. Then restart the phone. Do not clear the data of these services unless you know what you are doing. - 6
Reinstall the app
If the previous steps did not help, uninstall the app and install it again from the Play Store. This removes corrupted files of the app itself, but also deletes local app data. Before that, check if your data is saved in the cloud or on your account.

Start the phone in safe mode
Hold the power button and on the screen touch and hold
Power offuntil theSafe modeoption appears. In safe mode, only system apps run. If the problem does not occur, one of the installed apps is to blame. - 8
Perform a factory reset if necessary
If nothing helps, perform a factory reset only after making a backup. Go to
Settings > System > Reset options > Erase all data (factory reset). This deletes all data from the phone.
If all apps crash or the phone is unresponsive
When apps crash constantly and the phone freezes, first check if the problem is in a system update. Sometimes it is enough to wait for the manufacturer to release a patch. If crashes occur immediately after installing a new Android version, report the problem to the manufacturer through the support app. In the meantime, you can clear the cache partition through recovery mode, if your model offers it, but that is a more advanced step. If the phone still crashes in a loop, contact service or IT support because a hardware failure is possible. Do not try to "flash" the system yourself if you are not sure of the steps, because you risk permanent data loss.
How to prevent it
- Regularly update apps and the Android system
- Keep at least 10 percent of storage space free
- Avoid unknown themes and launchers that modify system files
- Occasionally restart the phone and clear the cache of large apps
When to call a professional
If apps crash even after all the steps, or the phone gets stuck in a boot loop, contact IT support or a service center. They can check the hardware, run system diagnostics, or perform a reset with a prior backup.

Does clearing the cache delete my data in the app?
No. Clearing the cache removes only temporary files, not the account, messages, or photos. Your data remains saved, and the app will download it again the next time you open it.
Why is only one app crashing?
The problem is most likely in the app itself: corrupted cache, incompatible version, or a bug in an update. First try clearing the cache, updating the app, and then reinstalling it if needed.
Is a factory reset the only solution?
No. Most crashes are resolved by clearing the cache, updating, or reinstalling. A reset is the last option when you suspect a serious system problem, and then be sure to make a backup.
