How to Fix Apps Crashing or Not Opening on Android (2026): Complete Fix Guide
There are few things more annoying than tapping an app and watching it flash open, freeze, and slam shut — or worse, refuse to open at all. Maybe it is your banking app crashing right when you need to pay a bill, WhatsApp closing the moment you attach a photo, or a game that worked yesterday and today will not get past the loading screen. Before you blame the phone or start shopping for a new one, know this: the vast majority of app crashes are software problems, and software problems are fixable. Corrupted cache, a buggy update, full storage, a denied permission, or an outdated system component like Android System WebView — these are the usual suspects, and each has a straightforward fix. This guide walks you through every fix in the right order, from the 10-second restart to Safe Mode detective work, so you stop at the step that solves your problem. The steps work on Samsung, Xiaomi, Oppo, Vivo, Realme, Infinix, Tecno and every other Android brand sold in Pakistan.

Why Apps Crash on Android: The Usual Suspects
Apps do not crash randomly — there is always a reason, and it is almost always one of these five. A corrupted cache is the single most common cause: apps store temporary files to load faster, and when those files get damaged (usually after an interrupted update or a phone running out of storage mid-write), the app chokes on its own data and closes. A buggy app update is next — developers ship updates that break on certain phone models or Android versions, and the Play Store reviews fill up with one-star complaints within hours. Full or nearly-full storage is the silent killer on budget phones: Android needs breathing room to run apps, and when free space drops below about 1 GB, apps start failing to launch or crashing mid-task. Denied permissions cause another class of crashes — an app that needs the camera, storage, or location permission and never got it can crash the instant it tries to use that feature. And finally, outdated system components like Android System WebView (which powers login screens and web views inside apps) or Google Play Services can take down dozens of apps at once when Google changes something on their end. Knowing which of these you are dealing with tells you exactly which fix to try — and the fixes below are ordered from fastest to most thorough, so work through them in sequence.
Start Here: The Two 60-Second Fixes
Most crashes are fixed by one of two things that take under a minute. Try these before anything else — they solve a surprising share of cases, and there is no reason to dig deeper if they work.
- Restart your phone. Not just locking the screen — a full restart. Hold the power button, tap Restart, and wait. This clears stuck background processes, releases leaked memory, and resolves temporary glitches in the Android system itself. If the app was crashing because of a one-off system hiccup, a restart ends it.
- Force stop the app and reopen it. Go to Settings > Apps, tap the crashing app, and tap Force stop, then open the app again. This kills the app completely — including background pieces that keep running after you swipe it away — and starts it fresh. If the crash was caused by a corrupted running state, this clears it.
If the app still crashes after both, move on to the targeted fixes below. Each one takes a few minutes, and each solves a different root cause.
Fix 1: Restart Your Phone (Properly)
Yes, this was in the quick fixes above — but it deserves emphasis because of how often people skip it. Many Android users go weeks without a real restart, and over that time the system accumulates stuck processes, fragmented memory, and background services in weird states. Hold the power button and choose Restart, not just the screen lock. On phones where the power button opens the voice assistant instead, hold Power + Volume Down together. After the phone boots back up, wait about a minute for everything to settle, then open the crashing app before opening anything else. If your phone does not offer a restart option in the power menu (some older budget models do not), power it off completely, wait 10 seconds, and power it back on. For crashes that appeared suddenly with no update involved, a restart is the fix more often than any other single step.
Fix 2: Force Stop the Misbehaving App
Swiping an app away from the recent-apps screen does not fully close it — background services and cached processes can keep running. Force stop ends all of them. Go to Settings > Apps (on Samsung: Settings > Apps; on Xiaomi: Settings > Apps > Manage apps), find the crashing app in the list, tap it, and tap Force stop. Confirm, then reopen the app from your home screen. If the app had a corrupted in-memory state — half-loaded data, a stuck network request, a frozen background thread — force stop wipes the slate clean without touching your saved data, logins, or settings. It is completely safe and is the first thing support teams ask you to try for a reason. Note that force stop does not fix deeper problems like corrupted cache, which is what the next fix is for.
Fix 3: Clear the App's Cache
Cache is temporary data apps save to load faster — thumbnails, pre-loaded pages, login tokens. When those files get corrupted, the app crashes every time it reads them. Clearing the cache deletes only these temporary files; your logins, settings, chats and saved files stay untouched. Go to Settings > Apps, tap the app, tap Storage & cache (or Storage on some brands), and tap Clear cache. Open the app again. This single step fixes a huge number of crashes, especially apps that crash on launch or when opening a specific screen. You can clear cache for any app as often as you like — it is maintenance, not surgery. Our full guide to clearing cache on Android covers doing this for all apps at once and explains exactly what cache does and does not delete.
Fix 4: Update the App — and Android System WebView
If a crash started right after an app update, or if you have not updated the app in a while, the Play Store is your next stop. Open the Play Store, tap your profile icon, tap Manage apps & device, and tap Update all — or update just the crashing app. Developers fix crash bugs in updates constantly, so an update that arrived after the crash started may already contain the fix. While you are there, search for and update two system components most people never think about: Android System WebView and Google Play Services. WebView is the engine that renders login pages, in-app browsers and embedded web content inside thousands of apps — when Google pushes a change, an outdated WebView can crash apps across your entire phone until it is updated. If the Play Store itself is misbehaving, our Play Store fix guide will get updates flowing again.
Fix 5: Clear App Data (When Cache Is Not Enough)
If clearing the cache did not help, the corruption may be in the app's main data — its saved settings, databases, and downloaded content. Clearing app data resets the app to a fresh-install state. The steps are the same as Fix 3, except you tap Clear data (or Clear storage) instead of Clear cache. Warning: this logs you out and deletes the app's locally stored files. For apps tied to an online account — Facebook, Instagram, Gmail, banking apps — this is harmless: log back in and everything syncs down again. But for apps that keep data only on your phone, back up first. WhatsApp is the big one: clear its data without a backup and your chats are gone, so run a manual backup first — our Android backup guide shows how. The same caution applies to offline games, note apps without cloud sync, and downloaded music or maps. After clearing data, open the app, log in, and test whether the crash is gone.
Fix 6: Free Up Storage Space
Android needs free space to work — apps download updates into it, write temporary files to it, and the system uses it as working memory. When your phone drops below roughly 1 GB free, apps start failing to update, failing to launch, and crashing mid-use, and the crashes often hit several apps at once. Go to Settings > Storage and check your free space. If it is tight, delete what you do not need: old downloads, duplicate photos and videos, WhatsApp media from dead groups, and apps you have not opened in months. The fastest wins are usually the phone's built-in storage cleaner and clearing cached data — our free up storage guide walks through nine methods that actually work, including finding the hidden storage hogs most cleaners miss. Aim to keep at least 2–3 GB free as a buffer; on phones with 32 or 64 GB total, this single fix ends more crashes than people expect.
Fix 7: Check the App's Permissions
Some apps crash the moment they try to use a feature you denied them. A camera app without camera permission, a maps app without location, a file manager without storage access — the app requests the permission at runtime, does not get it, and instead of handling the denial gracefully, it crashes. Go to Settings > Apps, tap the app, tap Permissions, and look for anything marked Denied that the app obviously needs. Grant what makes sense — a QR scanner needs the camera; a music player probably does not. While you are here, also check Settings > Apps > Special app access for anything unusual, like a battery-optimization exception that an aggressive cleaner app revoked. This fix is especially common for crashes that happen only when you tap one specific button inside the app, like the camera icon or the attach-file button.
Fix 8: Uninstall and Reinstall the App
When cache clearing, data clearing and updates have all failed, a clean reinstall gives you a completely fresh copy — new install files, fresh data directory, no leftover corruption from a half-finished update. Uninstall first, then reinstall (do not just install over the top): long-press the app icon and tap Uninstall, or go to Settings > Apps, tap the app, and tap Uninstall. Then install it fresh from the Play Store. Before uninstalling, make sure you know your login credentials and that anything important is backed up or synced — reinstalling a game without a linked account can lose your progress, and reinstalling WhatsApp without a Drive backup loses your chats. If the crashing app is a system app that cannot be uninstalled (like the camera or phone app on some brands), use Uninstall updates from the app's info screen instead — this rolls it back to the factory version, which often fixes crashes introduced by a bad update.
Fix 9: Update Android Itself
Sometimes the app is fine and the operating system is the problem. App developers build for the latest Android versions, and running a phone several versions behind — or running a system update that never finished properly — produces crashes that no amount of app-level fixing will solve. Go to Settings > System > Software update (Samsung: Settings > Software update; Xiaomi: Settings > About phone > System update) and install anything pending. Do this on Wi-Fi with the battery above 50% or the phone plugged in. After a major Android version update, also restart the phone once more and give apps a day to update themselves — the first 24 hours after a big update are the peak crash window, and most of it resolves on its own as app updates roll in. If your phone says no updates are available and it is several years old, that itself can be the cause: some newer app versions quietly drop support for old Android releases.
Fix 10: Boot Into Safe Mode to Find the Real Culprit
If one app crashes but everything else is fine, the app is the problem. If many apps crash, something else on your phone is interfering — and Safe Mode finds it. Safe Mode boots Android with only the pre-installed system apps running; every app you installed yourself is temporarily disabled. If the crashing app works fine in Safe Mode, you have proven that a third-party app is the cause. The usual suspects: aggressive RAM cleaners and battery-saver apps, antivirus apps, VPN apps, screen-overlay apps, and accessibility tools. To enter Safe Mode, hold the power button, then long-press the Power off option until you are offered Safe Mode (on Samsung: hold Power, then hold Power off). Test the app. Then restart normally to exit Safe Mode, and uninstall your recently installed or most suspicious apps one by one until the crashes stop — start with anything installed just before the crashes began. Our Safe Mode guide explains the whole process with brand-by-brand steps.
Fix 11: Reset All App Preferences
This is the fix almost nobody knows about, and it rescues phones where several apps misbehave at once. Over months of use, app defaults, disabled apps, blocked notifications, background restrictions and permission settings accumulate into a tangled state — a disabled system component here, a revoked background permission there — and apps start failing in confusing ways. Resetting app preferences restores all of these to their defaults without deleting any app or any data. Go to Settings > System > Reset options (Samsung: Settings > General management > Reset; Xiaomi: Settings > Additional settings), tap Reset app preferences, and confirm. You will need to re-grant a few permissions and re-set default apps afterward, but nothing is uninstalled and nothing is deleted. If your crashes involve disabled system apps or messed-up defaults, this is often the fix.
When the Problem Is the App's Servers, Not Your Phone
Not every crash is your phone's fault. If an app crashes only when you open a specific section — the feed, the messages tab, a live stream — while the rest of the app works, the app's own servers may be down or the developers may have shipped a broken update. Before spending more time: check the app's recent reviews in the Play Store and sort by newest — if dozens of users are reporting the same crash in the last few days, it is a bad update and no phone-side fix will help. Check the developer's social media or a status page for outage announcements. In this situation the right move is to wait for the developer's fix, and meanwhile you can try the app's website version in your browser as a workaround. If the app is critical — a banking app during a payment deadline, for example — installing the previous version of the app can buy you time; our guide to installing APKs safely explains how to do that without picking up malware.
Stop It Happening Again: 6 Prevention Habits
Once your apps are stable, a few habits keep them that way:
- Keep auto-updates on. In the Play Store, turn on auto-update over Wi-Fi so crash-fix updates install themselves instead of waiting for you to notice a problem.
- Do not let storage fill up. Keep 2–3 GB free at all times. Uninstall apps you no longer use instead of letting them sit and update in the background.
- Restart the phone weekly. A weekly restart prevents the slow accumulation of stuck processes that causes mystery crashes. Our slow phone guide has more maintenance habits along these lines.
- Be careful with cleaner and booster apps. Aggressive cleaner apps are a leading cause of crashes they claim to prevent — they kill processes apps need, revoke permissions, and corrupt cache. Android manages memory fine on its own.
- Install apps only from the Play Store. Apps from random websites are the main route for malware that destabilizes the whole phone. If an app behaves strangely after installing something from outside the Play Store, remove it — and read our guide on spotting a hacked phone if things look serious.
- Update Android when updates arrive. Delaying system updates for months leaves you on versions that newer apps no longer test against.
Work through this guide in order and the overwhelming majority of app crashes — the frozen launch screen, the instant close, the app that dies when you tap one button — resolve by Fix 5 at the latest. The deeper fixes are there for the stubborn cases, and Safe Mode is your detective when the culprit is another app entirely. A crashing app is almost never a reason to buy a new phone; it is a reason to spend ten minutes on maintenance.
FAQ
Why do my apps keep crashing after an Android update?
System updates sometimes break compatibility with older app versions, and the most common culprit is an outdated Android System WebView component. First update every app in the Play Store, then update Android System WebView from the Play Store too — Google ships crash fixes through WebView updates regularly. If a specific app still crashes after updating, uninstall and reinstall just that app. Also restart the phone once after a big Android update; leftover processes from the old system version are a frequent cause of crashes in the first day or two.
Is it safe to clear app data? Will I lose my photos and chats?
Clearing app data resets the app to a fresh install state: you will be logged out, and the app's own saved settings and offline files will be deleted. For most apps this is safe because your account data lives on the app's servers and comes back when you log in again. But think twice for apps that store things only on your phone — WhatsApp chats, for example, so back them up to Google Drive first. Your photos in the gallery and files in other apps are never touched by clearing one app's data.
An app will not open even after reinstalling. What should I do?
If a clean reinstall still does not fix it, the problem is probably outside the app. Check that your phone has at least 1 to 2 GB of free storage, update Android itself in Settings > System > Software update, and make sure Android System WebView and Google Play Services are updated. Boot into Safe Mode: if the app works there, another app on your phone is interfering — often an aggressive cleaner, battery-saver, or antivirus app. If it still crashes in Safe Mode, the app's developers likely broke something in their latest update; check the app's Play Store reviews for other users reporting the same crash, and wait for their fix or install a previous version of the app.
Can a virus or malware cause apps to crash?
Yes, though it is not the most common cause. Malware-infected apps or rogue adware can destabilize other apps and drain the phone. Warning signs include crashes appearing suddenly across many unrelated apps, new apps you never installed, and heavy battery drain. Run a scan with Google Play Protect inside the Play Store, uninstall any app you do not recognize — especially ones installed from outside the Play Store — and read our guide on how to tell if your Android phone is hacked for the full cleanup steps.
Why does only one specific app crash while everything else works fine?
That pattern points at the app itself, not your phone. A single crashing app usually means its cache is corrupted, its latest update has a bug, or it needs a permission it was denied. Force stop it, clear its cache, check that it has the permissions it asks for in Settings > Apps, and update it. If nothing helps, contact the app's developer through the Play Store listing — crash reports from users are how they discover and fix these bugs.
