Android Apps Keep Crashing? How to Fix Them on Your Phone
It is annoying when you open an app and it closes before you can use it. One moment you are about to reply to a message or check a map, and the next moment you are staring at your home screen again. When this happens once, it is easy to ignore. When it happens again and again, it starts to disrupt your day.
The good news is that most app crashes have ordinary causes. A temporary glitch, an outdated app, a full storage, or a setting that blocks the app can all make it shut down without warning. You do not need technical skills to work through these causes, and you do not need to reset your whole phone to fix one misbehaving app.
This guide walks you through the fixes in a sensible order, starting with the quickest ones. Try them one at a time and check whether the app behaves after each step. That way you will know what solved it.
Why Apps Crash in the First Place
An app is a small program running on top of your phone’s system, and it depends on several things working together. It needs enough free memory, enough storage space, a stable connection if it loads online content, and permission to use the parts of your phone it relies on. If any of these is missing, the app may close instead of showing an error.
Sometimes the problem is inside the app itself. A recent update can introduce a bug, or an old version can clash with a newer version of Android. In other cases, the problem is on your phone. A phone that is low on storage, running many apps at once, or waiting for a system update can struggle to keep apps running smoothly.
Start With the Quick Checks
Before changing any settings, try the simplest fixes. They take only a minute or two, and they solve a surprising number of crashes.
First, close the app completely and open it again. Swiping it away from your recent apps list ends its current session, so the next launch starts fresh. If the app froze on a particular screen, this alone may clear the problem.
Next, restart your phone. A restart clears temporary memory, stops stuck background processes, and gives every app a clean start. It is the oldest troubleshooting step for a reason, and it is worth doing early rather than after an hour of changing settings.
Also, check whether the problem affects one app or many. If only one app crashes, the issue is probably tied to that app. If several apps crash, the cause is more likely your phone’s storage, memory, or system software. This distinction will save you time, because it tells you whether to focus on a single app or on the phone as a whole.
Update the App and Your Phone
Outdated software is one of the most common reasons apps crash. Developers release updates to fix bugs, improve stability, and keep their apps working with newer versions of Android. If you are running an old version of an app, you may be running a version with a bug that has already been fixed.
Open your app store, find the crashing app, and check whether an update is available. If there is one, install it and test the app again. Also check whether other apps have pending updates, especially if several apps are crashing.
Your phone’s system software matters just as much. Go to your phone’s settings and look for a system update option. If an update is waiting, install it when you have a stable connection and enough battery. System updates often include stability improvements that help apps run more reliably.
Free Up Space and Clear the Cache
A phone that is nearly full can make apps unstable. Apps need room to store temporary files, save data, and update themselves. When storage runs very low, an app may fail to start or may close while it is working.
Check your storage in your phone’s settings. If it is almost full, delete files you no longer need. Old videos, duplicate photos, forgotten downloads, and apps you never open are good places to start. Back up anything important first, and only delete things you are sure you do not need.
Clearing an app’s cache is another gentle fix. The cache is a collection of temporary files the app stores to load faster. These files can become damaged over time, and a damaged cache can cause repeated crashes. Clearing the cache does not delete your account, your saved content, or your personal settings in most apps. It simply removes the temporary files, which the app will rebuild as you use it again.
To do this, go to your phone’s settings, open the app’s info page, and look for the storage option. Choose the option to clear the cache, not the option to clear data, which is a stronger step covered below. After clearing the cache, open the app and see whether it runs normally. If the crashes stop, you have found your fix without losing anything important.
Before You Clear Data or Reinstall: Read This
Clearing an app’s data and uninstalling an app are stronger steps than clearing the cache, and they deserve a warning. Clearing data usually returns the app to the state it was in when you first installed it. That can mean losing saved preferences, downloaded content inside the app, and settings you adjusted. Uninstalling and reinstalling has a similar effect, and anything stored only on your phone inside that app may be gone.
Before you take either step, check whether your important content is backed up or tied to an account. If the app asks you to sign in, your account content is usually stored online and will return when you sign in again. If it stores things only on your phone, such as notes or drafts, back those up first if the app lets you export them.
Do not clear data or reinstall as your first step. Work through the gentler fixes in this guide first, and only move to these stronger steps when the gentler ones have not helped. When you do take them, do so deliberately, knowing what you might lose, rather than tapping through options in frustration.
Check Permissions and Battery Settings
Some apps crash because they are not allowed to do something they need to do. For example, a camera app without camera permission, a messaging app without notification permission, or a navigation app without location permission may fail when it tries to use that feature. This does not always produce a clear message, and the app may simply close.
Go to the app’s info page in your settings and review its permissions. Make sure the permissions the app genuinely needs are allowed. Be thoughtful here: only grant permissions that make sense for what the app does. If an app asks for something unrelated to its purpose, you can leave that permission off and see whether the app still works.
Battery settings can cause a similar problem. Many Android phones include battery optimisation that limits what apps can do in the background to save power. This is usually helpful, but it can occasionally shut down an app you are actively using, or stop it from finishing a task. If an app crashes when you switch away from it and come back, battery optimisation is worth checking.
Look for a battery or power option on the app’s info page. If the app is heavily restricted, try a less restrictive setting and test again.
Use Safe Mode to Find the Culprit
If apps keep crashing and you suspect another app is interfering, safe mode can help you narrow it down. Safe mode starts your phone with only its built-in system apps, temporarily switching off apps you installed yourself. It does not delete anything, and your apps return to normal when you restart the phone again.
The exact way to enter safe mode varies by phone, but it usually involves holding the power button and choosing the safe mode option from the menu that appears. Once you are in safe mode, try the apps that were crashing and see whether the problem continues.
If the crashes stop in safe mode, an app you installed is likely involved. Think about which apps you installed or updated recently, especially ones that run in the background, change how your phone looks, or manage other apps. You can then restart normally and remove or disable suspects one at a time, testing after each change.
If the crashes continue in safe mode, the problem is more likely in the system software. Focus on system updates and storage, and consider seeking help from the phone maker’s support channels.
When One App Keeps Crashing
Sometimes every other app works fine and only one app refuses to cooperate. In that case, treat that app as a separate project. You have already tried restarting, updating, and clearing its cache. The next steps are to check its connection and its data.
Some apps depend on a steady connection to load content. If your connection is weak or switching between networks, the app may close while waiting for data. Try it on a different connection, such as switching between mobile data and Wi-Fi. A connection problem can look exactly like an app problem, so it is worth ruling out.
If you are dealing with slow mobile data alongside your crashes, it helps to sort the connection out first, since an app that cannot load its content will keep failing no matter how many times you restart it. The guide to fixing slow mobile data on Android walks through connection checks that can help here.
If the app still crashes, and you have backed up anything important, try clearing its data or reinstalling it. A fresh install removes corrupted files the cache clear may have missed. After reinstalling, sign in again if the app uses an account, and test it before changing many settings.
A Simple Order to Follow
When you are facing repeated crashes, it is easy to try everything at once and end up unsure what worked. A simple order keeps things clear. Start with a restart, then update the app and your phone. Next, free up storage and clear the app’s cache. Then check permissions and battery settings. If the problem continues, try safe mode to see whether another app is involved. Only after those steps should you clear data or reinstall, and only after checking your backups.
Frequently Asked Questions
Why do my apps keep crashing after I restart my phone?
If a restart does not help, the cause is probably not a temporary glitch. Update the app and your phone, free up storage, and clear the app’s cache. If several apps crash, check storage and system updates first. If only one app crashes, focus on its cache, permissions, and a possible reinstall after backing up anything important.
Will clearing the cache delete my photos, messages, or account?
Clearing the cache removes temporary files only, and it does not normally delete your account, photos, or messages. Clearing data is different and much stronger, so be careful not to confuse the two. Back up anything important before clearing data or reinstalling.
Should I uninstall an app the first time it crashes?
No, uninstalling should not be your first step. A single crash can be a temporary glitch that a restart will fix. Try restarting, updating the app, and clearing its cache first. Reinstall only when those gentler steps have failed and your important content is backed up or tied to an account.
Can a full storage really make apps crash?
Yes, it can. Apps need free space to store temporary files and to update themselves. When storage is nearly full, an app may fail to start or may close while it is working. Deleting files you no longer need and removing apps you never use can make a real difference, especially on phones with limited storage.
What if an app crashes only when I use a certain feature?
That pattern usually points to a permission, a connection, or a bug tied to that feature. Check whether the app has the permission that feature needs, and test it on a different connection if it loads online content. If it crashes every time, even after an update and a cache clear, it may be a bug in the app, and a future update is the likely fix.
Is safe mode dangerous for my phone or my apps?
Safe mode is not dangerous, and it does not delete your apps or data. It temporarily switches off apps you installed so you can test whether one of them is causing the problem. Restarting your phone normally brings everything back.
Conclusion
Apps that keep crashing are frustrating, but they are rarely a mystery once you work through the causes step by step. A restart, an update, some freed storage, or a cleared cache solves many crashes without any risk to your data. Permissions, battery settings, and safe mode help with the trickier cases, and a careful reinstall is there for the stubborn ones.
The key is patience and order. Try one fix at a time, check whether it helped, and protect your important content before taking stronger steps.
