You tap an app. It opens for half a second, then dumps you back on your home screen. You try again. Same thing. It’s one of the most frustrating things a phone can do to you, because it looks random — but it almost never is.
Apps keep crashing when your phone’s operating system shuts them down mid-run because they hit a problem they can’t recover from — usually low storage, a corrupted cache, insufficient RAM, an outdated app version, or a permissions conflict. Clearing the app’s cache, freeing up storage, and updating the app resolve the majority of cases without needing a factory reset.
That’s the short version. Here’s how to actually work through it, in the order that fixes the most crashes for the least effort.
Apps Keep Crashing- What’s Actually
An app crash happens when the app hits an error state the operating system decides it can’t safely continue from — so instead of freezing forever, the OS force-closes it. That’s a deliberate safety mechanism, not a glitch in how your phone works. The question is what triggered the error in the first place, and it’s almost always one of these:
- Storage is too tight. When your device is nearly full, apps can’t write the temporary files they need to run, and they crash instead of loading.
- Cache got corrupted. Apps store temporary files to load faster next time. Occasionally those files get damaged, and instead of speeding things up, they crash the app on launch.
- RAM is maxed out. Every open app eats memory. On phones with 2GB of RAM or less, the system force-stops background apps aggressively just to keep things running, which shows up as random crashes.
- The app or the OS is outdated. Developers ship updates specifically to patch the bugs causing crashes. Running an old app version against a new OS version — or vice versa — is one of the most common and most overlooked causes.
- Permissions are missing. If an app tries to use the camera, microphone, or storage and you’ve denied that permission, some apps handle the refusal gracefully. Others just crash.
- Malware or a bad download is interfering. Apps installed from outside the Play Store or App Store, or ones bundled with malvertising, can destabilize other apps on the device.
- The app’s own code has a bug. Sometimes it really isn’t you. Even well-built apps ship with crash bugs that only show up on certain devices or OS versions — that’s what the “force close” reports you sometimes see are actually collecting.
Knowing which of these applies to your situation is what separates a five-minute fix from an afternoon of trial and error, which is why the next step matters before you touch a single setting.
One App or All of Them? Diagnose It First
Before you start fixing anything, figure out the scope of the problem. It changes everything about where you should be looking.
If it’s just one app crashing, the problem is almost always local to that app: its cache, its permissions, its installed version, or a bug in that specific build.
If multiple apps are crashing at once, or your whole phone feels unstable, the cause is usually system-wide — low storage, low RAM, a pending OS update, or (on Android) a rogue third-party app interfering with everything else running. In that case, jumping straight to reinstalling one app won’t help, because the app isn’t really the problem.
A quick way to tell the difference on Android: boot into Safe Mode, which temporarily disables all third-party apps and runs only the stock software that came with your phone. If the crashes stop in Safe Mode, a third-party app is the culprit — usually something installed recently. If crashes continue even in Safe Mode, the issue is deeper: storage, RAM, or the OS itself.
Quick Fixes That Solve Most Crashes in 5 Minutes
Work through these in order. Most crash loops get solved somewhere in this list.
Force stop the app (not just close it)
Swiping an app away from your recent apps screen doesn’t always fully shut it down — parts of it can keep running in the background. Force stopping guarantees a clean kill.
- Android: Settings > Apps > [app name] > Force stop
- iPhone: Swipe up from the bottom, pause mid-swipe to see open apps, then swipe the app card upward
Restart your phone
This clears temporary memory, kills every background process at once, and resolves memory leaks — where RAM stays allocated to apps you already closed, quietly starving whatever you open next. It treats the symptom, not necessarily the root cause, but it’s the fastest way to rule out a temporary glitch.
Clear the app’s cache
Cached files are supposed to make an app load faster. When they get corrupted instead, they do the opposite.
- Android: Settings > Apps > [app name] > Storage > Clear cache
- iPhone: iOS doesn’t offer a per-app cache clear the way Android does. Offloading the app (Settings > General > iPhone Storage > [app] > Offload App) achieves a similar result without deleting your data.
Check app permissions
If an app needs camera, microphone, location, or storage access and doesn’t have it, some apps fail silently — others crash outright.
- Android: Settings > Apps > [app name] > Permissions
- iPhone: Settings > [app name] > toggle the relevant permissions on
Update the app
An outdated app build is frequently incompatible with a newer OS version’s underlying frameworks. Updating pulls in the exact bug fixes and stability patches the developer shipped for this.
- Android: Google Play Store > tap your profile icon > Manage apps & device
- iPhone: App Store > tap your profile icon > scroll to Available Updates
Quick takeaway: Force stop, restart, clear cache, check permissions, update. In that order, these five steps resolve the large majority of crash complaints — before you need to touch storage settings, Safe Mode, or a reset.
Android-Specific Fixes
If the quick fixes didn’t hold, these go a layer deeper and are specific to how Android manages apps and storage.
Clear app data (not just cache)
Clearing cache didn’t help? The next step is clearing app data, which resets the app to its fresh-install state. This is more aggressive — it signs you out and wipes in-app settings — so use it only after cache clearing fails. Go to Settings > Apps > [app name] > Storage > Clear data.
Free up storage space
When internal storage runs low, apps can’t write the temporary files they need and start crashing — this is one of the single most common causes across both Android and iPhone. Go to Settings > Storage to see what’s eating your space, then:
- Uninstall apps you no longer use
- Delete large videos and duplicate photos
- Move photos and videos to a cloud service like Google Photos to free space without losing anything
- Clear out your Downloads folder
As a rule of thumb, keep at least 10–15% of your total storage free, and don’t let available space drop below roughly 1GB — devices running tighter than that see crashes climb sharply.
Boot into Safe Mode to catch third-party conflicts
Covered above as a diagnostic step, but worth repeating as a fix: if Safe Mode confirms a third-party app is the cause, uninstall the most recently installed app first, since that’s the most common trigger.
Wipe the cache partition
This is a system-level step most guides skip entirely, but it’s genuinely useful when multiple apps crash after an update. It clears the system cache (not any individual app’s cache), which can resolve conflicts left behind by an OS update. The exact steps vary by manufacturer, but generally: power off the device, then hold the power button + volume down (or volume up, depending on your model) to enter recovery mode, and select “Wipe cache partition.” This does not delete personal data.
iPhone-Specific Fixes
iOS handles background processes and storage differently than Android, so a few steps look different here.
Update iOS
If an app is crashing right after you update iOS — or right before an app update arrives — the app’s core frameworks may be temporarily out of sync with the new OS. Go to Settings > General > Software Update. If a fix isn’t out yet for the app itself, sometimes the answer is simply waiting a few days for the developer to ship a compatible update.
Offload or reinstall the app
Offloading (Settings > General > iPhone Storage > [app] > Offload App) removes the app but keeps its documents and data, so you don’t lose anything when you reinstall from the App Store. If offloading doesn’t help, a full delete-and-reinstall clears out everything, including any corrupted local files — but check first whether the app backs up your data to its own servers or iCloud, since apps that only store data locally (some games, for instance) will lose that progress on reinstall. Apps with account-based data, like most social apps, sync from the server and won’t lose anything.
Reset all settings
If crashes are widespread and nothing above has worked, Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings clears system-level preferences (Wi-Fi passwords, permissions, layout) without deleting your photos, apps, or files. It’s a smaller step than a full restore and catches a surprising number of stubborn, system-wide crash loops.
When It’s Not the App — Deeper Fixes
Low RAM and older devices
Devices with 2GB of RAM or less are especially prone to the system force-stopping background apps just to free memory, which shows up to you as a crash. If you’re on an older or budget device, routinely closing unused apps and keeping storage well above the minimum threshold matters more than it does on newer hardware.
Malware and shady downloads
Apps sideloaded from outside the Play Store or App Store, or bundled with malicious ads, can destabilize other apps running on the device — not just themselves. If crashes started after installing something from an unofficial source, that app is the first thing to remove.
Factory reset (last resort)
If you’ve tried the storage, cache, permissions, and update fixes and crashes are still happening across multiple apps, a factory reset wipes the device back to its out-of-box state and resolves almost any software-level conflict. Back up your data first — this deletes everything, not just app data.
When it’s actually a hardware problem
If you’ve worked through every software fix and the crashes persist — especially if they’re accompanied by overheating, random reboots, or a swollen battery — you’re likely looking at a hardware issue rather than a software one. At that point, further troubleshooting on your own won’t help, and it’s worth getting a professional diagnosis rather than repeatedly resetting the device.
Android vs. iPhone: Which Fix to Try First
| Situation | Android — Try First | iPhone — Try First |
|---|---|---|
| Just one app crashing | Clear app cache | Offload the app |
| Multiple apps crashing | Boot into Safe Mode | Reset All Settings |
| Crashes after an OS update | Wipe cache partition | Wait for app update, or update iOS fully |
| Storage nearly full | Settings > Storage, delete/move large files | Settings > iPhone Storage, offload unused apps |
| Nothing else has worked | Factory reset (back up first) | Erase All Content and Settings (back up first) |
How to Stop This From Happening Again
Once things are stable, a couple of habits keep it that way. Set apps and your OS to auto-update over Wi-Fi so you’re not running outdated builds. Keep an eye on your storage before it gets critically low rather than after apps start misbehaving. And if you install apps outside the official store, know that you’re taking on more crash risk in exchange for whatever that app offers. None of this is glamorous, but it’s the difference between fixing this once and fixing it every month.
If you’ve worked through the list above and something is still crashing on repeat, that’s usually your signal it’s either a deeper OS conflict or a hardware issue — worth a factory reset or a professional look before you keep guessing.

FAQ Section
Q1: Why do my apps keep crashing? Most crashes come down to low storage, a corrupted app cache, insufficient RAM, an outdated app or OS version, or a denied permission the app needed. Rule out storage and cache first — they cause the majority of cases.
Q2: How do I stop an app from crashing? Force stop it, restart your phone, clear its cache, check its permissions, and update it to the latest version. These five steps, tried in order, resolve most crash loops without needing a factory reset.
Q3: Does clearing cache actually stop apps from crashing? Yes, in a large share of cases. Cached files are supposed to speed up loading, but corrupted cache files trigger crashes instead — clearing them forces the app to rebuild clean files from scratch.
Q4: Can low storage cause apps to crash? Yes. When storage runs low, apps can’t write the temporary files they need to function and crash as a result. Keeping 10–15% of your storage free is a reasonable safety margin.
Q5: Will I lose data if I reinstall a crashing app? It depends on the app. Apps that sync data to their own servers or iCloud (most social and productivity apps) won’t lose anything. Apps that store data only locally, like some games, will lose that data unless you’ve backed it up first.
Q6: Can too many open apps cause crashes? Yes, especially on devices with 2GB of RAM or less. Too many apps running in the background strain available memory, and the system force-stops apps to compensate, which you experience as a crash.
Q7: Why did all my apps start crashing after an update? An OS update can temporarily leave app frameworks out of sync until the app itself is updated to match. Wiping the system cache partition (Android) or waiting for app-side updates (iPhone) usually resolves it within a few days.
Q8: Is repeated app crashing a sign of a bigger phone problem? Sometimes. If crashes continue after you’ve tried storage, cache, permission, and update fixes — especially alongside overheating or random reboots — it may point to a hardware issue that needs professional diagnosis.
