This might sound familiar: you're using your favorite app and, without warning, it closes unexpectedly. It can happen while you're sending an email, editing a document, or simply browsing, and it's incredibly frustrating. Here you'll find a comprehensive and up-to-date guide with all the common causes and the most effective solutions so you can get back to normal without wasting any time.
Your mobile phone is essentially a pocket computer . It combines hardware, an operating system, and applications that rely on memory, storage, and connectivity. When something goes wrong in this chain, unexpected crashes occur. Below, we've compiled a step-by-step guide to the most common causes and how to fix them , including special cases like Android System WebView, battery settings that kill processes, and maintenance tips that make a real difference.
Why do apps close on their own on Android?
In most cases, the problem isn't a single issue, but rather a combination of factors. Understanding the root cause allows for a faster and more effective response, avoiding drastic measures initially.
- Too many open appsEach app consumes CPU and RAM. If you run out of heap memory, Android will kill processes to breathe and keep the system stable.
- Storage almost full- Many apps require temporary space to run; without space, crashes increase, screen freezes appear, and the system cannot save new data; you can free up storage on your smartphone.
- Errors in the app itself- A bug, a bad interaction with another app, or very intensive use (rapid clicks, multiple simultaneous actions) can trigger an unexpected shutdown.
- Malware or suspicious apps: Malicious software can force shutdowns, consume resources, and cause instability. It's a good idea to scan your device if you notice persistent strange behaviors.
- OverheatingIf the device is too hot, Android limits processes and closes apps to protect the hardware.
- Outdated system or apps: Updates fix compatibility issues and bugs that cause crashes; postponing them too long it usually takes its toll; see how avoid errors when updating.
- App exceeding its memory limit: Each app starts with a certain amount of memory allocated; if it exceeds this limit, it may crash and exit.
- Unstable connection: In network-dependent apps, erratic Wi-Fi or running out of data causes apparent freezes and crashes due to an inability to complete requests.
Quick and effective solutions if your apps close on their own
Before delving into advanced settings, it's best to start with the simple and work your way up to the complex. These steps usually resolve most issues and require minimal time.
Restart the app or your phone
Close the app from the multitasking view and reopen it; if the problem persists, turn your phone off and on again to clear background processes that might be stuck and restore stability.
Clear the app's cache and data
In Settings > Apps > select the app > Storage, clear the cache, and if it still doesn't work, clear the data as well. This resolves internal conflicts and corrects memory errors that prevent the app from starting properly.
Update the app and Android
Open the app store and check for updates to the problematic app. New versions usually include performance improvements and stability patches . If that doesn't work, check your system for pending updates in Settings > Software Update.
Free up memory and close what you don't use
Close background apps from the multitasking menu and, if your Android skin includes it, use the built-in optimization to clean up unnecessary processes. You'll free up RAM and reduce crashes due to system overload . Keep in mind that closing apps doesn't save battery.
Uninstall and reinstall
If the app continues to crash after trying the above, uninstall it and reinstall it from the official store. This will remove corrupted files and recreate the app from scratch.
The special case of Android System WebView and MSA-type errors
Android System WebView allows applications to display web content within the app itself. When a WebView update fails, many apps that rely on it crash as soon as a link is opened or certain views are launched.
If you see messages like "MSA has stopped working" or crashes in apps like Gmail , Outlook, Google, or similar, try reverting WebView. The process is simple and fixes the problem in just a few steps.
How to uninstall WebView updates
- Go to Settings > Apps (or Apps & notifications) and tap See all apps to display the full list, including those of the system.
- Open the three-dot menu and select Show system apps. Find Android System WebView.
- Go to the tab and tap Uninstall updates. Accept the confirmation and, if necessary, restart your phone to complete the change. go back to stable version.
If Android System WebView appears disabled, the system might be using the WebView provider from Chrome or another browser. In that case, update your browser or temporarily enable WebView to manage its updates and revert them if necessary.
Connection and Play Store: two checks to avoid scares
Some apps rely on a constant network connection; with a weak or unstable signal, they may freeze or close. Make sure your Wi-Fi or mobile data connection is available and has good coverage.
Check connectivity
Swipe down the quick settings panel and check your Wi-Fi or mobile data status. If you're on a public network and experiencing slow speeds, move to a location with better signal or switch to mobile data. Some manufacturers allow you to choose whether an app works with Wi-Fi only, mobile data only, or both; check this setting if the app isn't loading correctly . If you're experiencing poor coverage, try improving your signal strength.
Update Google Play Store
The Play Store is also being updated with important security and stability fixes. Open the store, tap your profile icon > Settings > About, and tap Update Play Store to force the update . If you're experiencing download errors, follow the guide to troubleshoot app download problems.
Diagnostics: Identify which apps close automatically
When you don't know what's causing the problem, safe mode is your best friend. In this mode, only the essential system functions run, making it easier to determine if a third-party app is responsible and take appropriate action.
Boot into safe mode
- Press and hold the power button until you see the menu.
- Tap Power off and hold Power off until Safe Mode appears. Accept to restart in Safe Mode and test without third-party apps.
If everything works in safe mode, uninstall the suspicious applications one by one and check. If the problem persists even in safe mode, it's more likely a system or global configuration issue.
Complementary measures to improve stability
Force stop a stuck app
Go to Settings > Apps > select the app > Force stop. Use this wisely: there are essential system processes (keyboard, clock, Google services) that you shouldn't touch. Before forcing anything, make sure you know what you're closing.
Create more storage space
If your phone is running out of storage, it's likely to crash. Free up storage by moving photos and videos to the cloud or a USB drive, delete downloads, and uninstall apps you don't use. You'll gain space and avoid crashes due to lack of storage.
- Move heavy content (photos, videos) to the cloud or to a pendrive with OTG to quickly free up gigabytes.
- Uninstall games and apps that you no longer use, especially those that take up hundreds of megabytes.
- Empty the Downloads folder, where duplicates and forgotten files accumulate.
Clearing data vs. clearing cache: when to use each option
Clearing the cache removes temporary files and is usually safe; clearing data resets the app to its original state. Start with the cache, and if that's not enough, clear the data after backing up anything important to avoid unnecessary loss.
Review app permissions
An app can malfunction if it lacks essential permissions (such as storage, location, or camera). In Settings > Apps > Permissions, adjust the necessary permissions and use logic: a weather app might require location access but not microphone or camera access.
Wipe the system cache partition
The cache partition stores temporary system files. Over time, these can become corrupted and cause system crashes. From recovery mode, you can clean this partition without deleting your personal data and restore smooth performance.
- Turn off the device.
- Boot into recovery mode using your model's key combination (usually volume up + power).
- Select Wipe cache partition and confirm. The first boot will take a little longer, but the storms will regenerate clean.
When nothing works: factory reset
This is the last resort. It will erase your entire phone and require a complete reset after a full backup. You can do this in Settings > General management > Reset > Factory reset, but be aware that you will lose any local data if you haven't backed it up.
Prevent Android from killing your background apps
Many app crashes are due to power-saving policies. Android and manufacturer skins restrict processes to conserve battery, sometimes overly so. Adjust these settings to keep your critical apps running and avoid missing notifications.
Remove battery optimization from essential apps
- In Settings > Apps, go to the desired app.
- Open Battery > Battery Optimization and switch to Don't optimize for apps that require it. constant activity (messaging, mail, music, maps).
Keep the impact in mind: the more apps you exclude from optimization, the higher your battery consumption will be. Select only the essential ones; see tips for optimizing your battery.
Block apps in multitasking so that the system doesn't close them
On operating systems like MIUI, ColorOS, or realme UI, open the recent apps view, press and hold the app's view, and tap the lock icon. This prevents it from closing when you clear memory and ensures it remains active.
Disable deep sleep on Samsung
In One UI, go to Device care > Battery and check Sleep/Always-on apps. Remove any apps from those lists that you need real-time notifications for.
Developer Options: Background Usage Check
If you know what you're doing, enable Developer Options and look for Background Usage Check. If your favorite app is checked, disable it to prevent forced closures and save battery.
RAM problem? What can you do and what can't you do?
Android manages memory quite efficiently, but on phones with very limited RAM, it's common for apps to close unexpectedly if you open several at once. Closing background processes and keeping only what's necessary helps reduce crashes due to insufficient memory.
Some users resort to creating virtual memory with a microSD card using apps like SWAP without root access. This technique can alleviate some of the load, although its effectiveness is not comparable to having more physical RAM and it is not a universal solution.
How to expand virtual RAM with a microSD (using sharing apps)
- Insert the microSD card and launch the chosen memory swapping app.
- Select the virtual memory size you want to generate and create the swap file.
- In certain cases it is required to watch ads to get credits and press Create swap, after which the app will enable virtual memory.
If your phone is entry-level or very old, the experience may still be limited by CPU limitations, slow storage, or Android's own resource management. In these cases, it's advisable to prioritize lightweight apps, minimize processes, and consider a device upgrade if your usage requires it.
Malware and intrusive apps: how to rule out this cause
If, in addition to app crashes, you notice unusual data usage, inappropriate ads, or unwarranted overheating, run a scan with a reliable security tool. The goal is to detect and remove persistent software that may be interfering with your apps . If you suspect an infection, follow our guide to removing viruses from your mobile device.
Also, check the permissions: a weather app shouldn't request microphone or camera access. Uninstall hacked or suspicious apps and avoid granting access that isn't essential for the app's functionality.
Thirteen ordered measures to attack the problem at its root

- Force stop: Settings > Apps > conflicting app > Force stop and reopen.
- Reboot the device: sometimes it is enough to clean up blocked processes.
- Free up storage: Move content, delete downloads, and uninstall heavy apps.
- Delete app data: Settings > Apps > app > Storage > Clear data if clearing cache was not enough.
- Clear the cache: Settings > Apps > app > Storage > Clear cache to remove corrupted temporary files.
- Reinstall the app: uninstall and download again from the official store.
- Check permissions: Settings > Applications > app > Permissions and grant only what is necessary.
- Wipe the cache partition: From recovery, wipe the system cache without touching your personal data.
- Factory reset: last option, always after a full backup.
When is it good for Android to close background apps?
Not all app closures are bad. Automatic process management improves battery life and prevents your phone from lagging. As with everything, balance is key: it's good to let the system do its job, but also to protect critical apps. These are the positive effects of automatic app closure.
- Battery saving: Fewer active processes mean lower energy consumption and more hours away from the charger.
- Better performance: By freeing up RAM, the apps you do use run more smoothly.
- Lower data usageSome apps use data in the background; closing them reduces this hidden usage.
- Less overheating: With less sustained load on the CPU, the risk of high temperature decreases.
- Privacy & Security: You close the door to malicious apps that collect data without you noticing.
- Less processor load: fewer simultaneous tasks, greater hardware efficiency over time.
Best practices to prevent apps from closing on their own
Adopting certain habits drastically reduces the likelihood of system crashes: keep your system and apps up to date, always maintain some free space, avoid overloading your system with open apps, review permissions, and exclude only essential features from optimization. These are simple measures that have an immediate impact.
If you've made it this far, you already have a clear plan: identify the likely cause, apply the most appropriate solution (from WebView to battery settings, including cache and storage), and perform regular maintenance. With these guidelines, your Android should stop closing apps unexpectedly and offer a much more stable daily experience.
