If your phone kicks you out of apps, suddenly returns to the home screen, or displays messages like "the app stopped working," it's almost always due to lack of memory, full storage, app errors, corrupted temporary files, battery restrictions, or operating system problems.
The quickest solution is to restart your phone, free up space, update the app, and clear its cache. If the problem occurs with all apps, you should check the internal storage, system updates, temperature, and overall device health.
In this guide you will find all the possible causes and solutions for Android and iPhone, ordered from the simplest to the most advanced.
When does the app kick you out? Select the option that best describes your situation:
Some of these causes depend heavily on the condition and brand of the cell phone.
Try these steps in the order shown:
Before making major changes, identify whether the problem occurs with only one application or with all of them. This distinction allows you to find the cause much faster.
RAM (Random Access Memory) is where your phone "thinks." When it fills up with the operating system, your open apps, and background processes, the memory manager starts killing apps to free up space. This is completely automatic.
Signs that confirm it: The app closes right when you open another one. When you return to the app, it's reloading from scratch. The phone has 3 GB of RAM or less. You have many apps open at the same time. Quick solution: Close the apps you don't use and consider a phone with more RAM for your next purchase.
The processor (CPU and GPU) generates heat while working. When the temperature exceeds certain safety limits—generally between 45°C and 55°C—the operating system reduces the chip's speed and may close apps to prevent permanent hardware damage.
Signs that confirm it: The back of the phone feels hot. The problem occurs after prolonged use. It happens when playing games or watching high-resolution videos. It shuts down while charging and using it simultaneously. Quick solution: Rest the phone, remove the case, avoid charging it while using it intensively.
Apps need storage space not only to install, but also to store cache, temporary data, downloads, and ongoing updates. When storage is below 10% free, the system becomes unstable and apps start crashing. Signs of this include: "Storage almost full" notifications; apps take a long time to open; photos and videos aren't saving; and the system is generally slow. Quick fix: Free up at least 10-15% of your total storage. Start with your gallery and downloaded files.
Apps are constantly being updated. Sometimes an update introduces bugs (code errors) that cause unexpected crashes. It can also happen that the app's saved data becomes corrupted, especially if the phone unexpectedly shut down while the app was writing data. Signs that confirm this: Only that specific app crashes; it started after a recent update; the app displays a "Stopped" message; it works fine on another phone.
Quick fix: Clear the cache, update, or reinstall the app. If the bug is on the developer's end, wait for a fix update.
The operating system is the foundation on which all apps run. If it has unfixed bugs or is very outdated, it can cause compatibility issues with modern apps. Some manufacturers also modify Android in ways that introduce additional bugs. Signs that confirm this: Multiple different apps keep crashing; the problem started after a system update; the phone is old and no longer receives updates; the system is generally behaving erratically.
Quick fix: Update your OS if versions are available. If the problem started after updating, wait for a patch.
A degraded or damaged battery can deliver unstable voltage to the processor and other components. This can cause the phone to shut down unexpectedly or apps to close without warning. It's common in phones older than three years or those that have been repeatedly charged incorrectly. Signs that confirm this include: the battery drains very quickly (less than four hours of normal use); the battery percentage fluctuates erratically; the phone shuts down even when it shows 20% or more; and the phone is more than three years old.
Quick fix: Check your battery status in Settings (on iOS, it's under Battery → Battery Health). If it's below 80%, consider replacing it.
RAM is your phone's working memory. When it's full, the operating system kills background apps to free up space.

2. Disable apps that consume RAM in the background. Go to Settings → Applications → find social media or music apps and disable their background activity.
3. Restart your phone regularly. A restart completely clears the RAM. Do this at least once a day if you have a phone with limited memory.
4. Check RAM usage in real time. On Android: Settings → Device management → Memory. There you can see which apps are using up your RAM.
5. Disable system animations. In Developer Options (if you have them enabled), reduce the animation scale to 0.5x to free up some processing power.
2. Lower screen brightness. The screen is a major source of heat. Lower the brightness to the minimum necessary and activate dark mode.
3 Activate low power mode. This limits the processor cores and reduces the clock speed, generating less heat.
4. Avoid charging it on hot surfaces. Do not charge your phone on beds, pillows, or in direct sunlight. Use hard, flat surfaces.
2. Clear app cache: Settings → Apps → select each app → Clear cache. Especially useful for browsers and social media.
4 Install an app on an SD card (Android) If your phone has a microSD slot, move apps that allow it to the card to free up internal storage.
2. Update the app. Go to the app store and update the app that's giving you problems. Updates fix stability bugs.
3 Uninstall and reinstall If nothing works, completely uninstall the app and reinstall it from the official store.
4. Check app permissions. Some apps close because they lack the necessary permissions. Settings → Applications → [App] → Permissions.
2. Check if a recently installed app is causing conflicts. If the problem started after installing something, that app might be the culprit. Uninstall it and try again.
3. Boot into Android safe mode: Press and hold the power button → tap "Safe mode". If the problem disappears, a third-party app is the cause.
4. Last resort: factory reset. Make a full backup first. Then go to Settings → System → Reset → Erase all data. This fixes almost everything.
The problem can manifest itself in several ways:
