You launch your favorite game or instant messenger on your smartphone, and after a few seconds - bam! — the application closes by itself. Is this a familiar situation? Such sudden crashes (crash) are not only annoying, but can also signal serious problems in operation Android. In this article we will analyze why applications close without warning, and give 10 main reasonswhy applications close without warning, and we’ll give step-by-step solutions for each of them - from banal lack of memory to hidden firmware errors.

It is important to understand: if crashes occur only in one application (for example, in Instagram or PUBG Mobile), the problem most likely lies in it itself. But when all apps close chaotically the system is to blame. We will teach you how to distinguish one from the other and tell you when to contact a service center and when you can handle it yourself. Let's start with the most obvious reasons and gradually move on to complex technical nuances.

1. Lack of random access memory (RAM)

The most common reason for crashes is RAM overload. Modern applications (especially games and social networks) require more and more resources. If your Samsung Galaxy A52 or Xiaomi Redmi Note 11 has 15 tabs open at the same time in Chrome, a couple of other games are running Telegram, YouTube in the background - the system simply does not have enough memory for stable operation.

Android tries to free up resources by forcefully closing the least priority processes. Sometimes it happens so suddenly that you don't even have time to see the notification. How to check?

  • 📱 Open Settings → Memory → RAM usage (the path may differ depending on the shell).
  • 📊 If free less 15-20% of the total volume is a critical level.
  • 🔄 See which applications consume the most memory (browsers and instant messengers are often to blame).

Solutions:

  • 🧹 Close unnecessary applications via Recent tasks (swipe up from the bottom edge screen).
  • 🚫 Disable autorun of unnecessary apps in Settings → Applications → Autorun.
  • 🔄 Reboot the device - this clears the cache and frees up memory.
💡

On smartphones with 4 GB RAM or less, avoid multitasking. Close games and heavy applications immediately after use, rather than leaving them in the background.

2. Conflicts with cache and application data

Cache and temporary files speed up apps, but over time they can get damaged or overflow. This leads to crashes - the application tries to access broken data and closes. This happens especially often after updates or when using one app for a long time without cleaning.

Symptoms of the problem:

  • 🎯 Crashes occur only in one or two applications (for example, VKontakte or Google Maps).
  • 🔄 After rebooting the smartphone, the problem temporarily disappears.
  • 📥 The application takes a long time to load or freezes before closing.

How to clear the cache:

  1. Go to Settings → Applications.
  2. Select the problematic application (for example, Facebook).
  3. Click Storage → Clear cache.
  4. If that doesn’t help, try Clear data (attention: this will delete all settings and logins!).

If cleaning did not help, try reinstall the application:

  1. Uninstall it via Settings → Applications.
  2. Download the latest version from Google Play.
  3. Run and check work.

3. Outdated version of Android or application

Developers regularly release updates to fix bugs and improve compatibility. If your Android 10 has not been updated for a long time, and the application requires Android 12+, conflicts cannot be avoided. outdated version WhatsApp may not work correctly on new firmware.

How to check:

  • 📱 For the system: Settings → System → Software update.
  • 📥 For applications: open Google Play → Profile → Manage applications → Updates.
Android version Update support (approximately) Risk of crashes
Android 8.0 Oreo Completed in 2021 ⚠️ High
Android 9.0 Pie Completed in 2022 ⚠️ Medium
Android 10 Completed in 2026 ⚠️ Low
Android 11+ Active support ✅ Minimum

What to do if there are no updates:

  • 🔍 Check if the manufacturer is blocking updates (relevant for Huawei, Honor and some models Samsung).
  • 🛠️ Install custom firmware (only for experienced users!).
  • 📲 Use alternative versions applications (for example, WhatsApp Business instead of the usual WhatsApp).

Regularly, immediately after release|Once a month|Only when they stop working|Never update-->

4. Viruses and malware

Malware can not only steal data, but also damage system fileswhich is why applications start Particularly at risk are users who:

  • 📲 Install APK files from unverified sources.
  • 🔓 Disable protection Google Play Protect.
  • 💳 Enter payment information on suspicious sites.

Signs of infection:

  • 🚨 Applications close immediately after launch.
  • 📱 Smartphone overheats for no apparent reason.
  • 🔋 The battery discharges 2-3 times faster usually.
  • 📎 Appear unknown applications in the menu.

How to check and clean:

  1. Install an antivirus (Kaspersky, Dr.Web, Malwarebytes).
  2. Run full scan system.
  3. Remove all suspicious files and apps.
  4. Reset the settings to factory settings (Settings → System → Reset) if viruses are not removed.
What to do if the antivirus does not find threats, but problems remain?

In some cases, viruses disguise themselves as system processes. Try:

1. Boot into Safe Mode (hold the shutdown button → "Restart in safe mode").

2. Check the operation of applications - if crashes occur. stopped, third-party software is to blame.

3. Uninstall the latest installed apps.

4. If this does not help, perform a factory reset.

5. Damage to system files or firmware

If applications are closed even after resetting, the problem may lie in damaged system files or incorrectly installed firmware. This often happens after:

  • 🔄 Unsuccessful over-the-air (OTA) update.
  • 🛠️ Independent firmware via Odín or Fastboot.
  • 💥 Abrupt power outage during critical operations.

How to diagnose:

  • 📱 Check Settings → System → Software update —if the update freezes at 0%, the firmware is damaged.
  • 🔧 Run adb logcat in debug mode (for advanced users) - look for type errors E/AndroidRuntime: FATAL EXCEPTION.
  • 📊 Use applications to check the integrity of the system, for example Phone Doctor Plus.

Solutions:

  • 🔄 Try force reinstall firmware through the manufacturer's official utilities:
    • Samsung: Odín + proprietary firmware with Sammobile.
    • Xiaomi: Mi Flash Tool + firmware with en.miui.com.
    • Google Pixel: Android Flash Tool.
  • 🛠️ If it doesn’t help, contact the service center for flashing via box.
⚠️ Attention: Incorrect firmware can turn a smartphone into a “brick”. If you are not confident in your skills, entrust it to professionals. Manufacturers (for example Samsung or Xiaomi) may void the warranty if traces of unofficial firmware are detected.

6. Conflicts with root access or modified firmware

Users who receive root access or install custom firmware (for example, LineageOS) often experience crashes due to:

  • 🔧 Incompatibility of Magisk/Xposed modules with applications.
  • 🛡️ SafetyNet locks (many banking applications and games require a certified device).
  • 📦 Uninstalling system applicationson which other apps depend.

How to check:

  • 📱 Install Magisk Manager and check status SafetyNet.
  • 🔍 Run adb shell su -c "logcat | grep -i crash" to search for errors.
  • 📊 Check the list of installed modules in Magisk —disable them one by one to find the culprit.

Solutions:

  • 🔄 Disconnect all Magisk modules and restart the device.
  • 🛡️ Install the module Universal SafetyNet Fix to pass the test.
  • 📦 Restore deleted system applications via Titanium Backup or reflash the device.
💡

If you are using root or custom firmware, be prepared for the fact that some applications (for example Google Pay or SberBank Online) may refuse to work. This is due to the security policy, and not to errors in your device.

7. Problems with storage (memory is full or damaged)

When the internal memory of the smartphone Filled by 90% or more, Android begins to work unstable. Applications do not have enough space for temporary files, which leads to crashes. Problems may also arise due to:

  • 💾 Damaged sectors Storage (relevant for older devices).
  • 🔄 Incorrect formatting SD card (if it is used as internal memory).
  • 📁 File system error (for example, after a sudden power outage).

How to check:

  • 📱 Open Settings → Storage —if free less 1-2 GB, this is a critical level.
  • 🔧 Run adb shell df -h for detailed information about partitions.
  • 📊 Use applications like SD Maid to search for "junk" files.

Solutions:

  • 🧹 Clear cache and unnecessary files (see section 2).
  • 📁 Transfer photos and videos to Google Photos or an external drive.
  • 🔄 Format the SD card (if used) to Settings → Storage → SD card → Format as internal.
  • 🛠️ If the memory is damaged, perform factory reset settings or replace the drive (at a service center).
⚠️ Attention: On devices with eMMC memory (most budget smartphones), frequent data rewrites accelerate chip wear. If your Redmi 9A or Samsung Galaxy A10 is older than 3 years and constantly slows down, the problem may be “fatigue” of memory. In this case, only replacing the board will help.

8. Overheating of the processor or battery

Android automatically closes applications if the temperature of the processor or battery exceeds 45-50°C. This is protection against damage, but often triggers falsely - for example, in hot weather or during intense gaming. Particularly susceptible to overheating:

  • 📱 Smartphones with processors Snapdragon 8xx (for example, OnePlus 8 Pro, Xiaomi Mi 11).
  • 🔋 Devices with old batteries (capacity below 70% of the nominal value).
  • 🎮 Gadgets in cases or when charging while playing.

How to check the temperature:

  • 📱 Install AIDA64 or CPU Monitor.
  • 🔍 Look at the section Sensors —the processor temperature should not exceed 40°C idle and 60°C under load.

Solutions:

  • 🧊 Remove the cover and let allow the device to cool down.
  • 🔌 Do not play heavy games while charging.
  • 🔄 Close background applications (see section 1).
  • 🔋 If the battery is swollen or discharges quickly - replace it.
  • 🛠️ Apply new thermal paste (relevant for collapsible models, for example Samsung Galaxy S10).
💡

If your smartphone overheats even when idle, check to see if there is a mining bot running in the background. Some viruses use device resources to mine cryptocurrency.

FAQ: Frequently asked questions about application crashes

❓ Why does only one application crash, while the rest work fine?

Most likely, the problem is in the application itself. Try:

  1. Clear its cache and data (see section 2).
  2. Update to the latest version.
  3. Reinstall.
