Even premium devices from Apple Inc. and Samsung Electronics are not immune to this issue. The good news? Most app crashing problems are easy to diagnose and fix.
In this comprehensive guide, you’ll learn why apps crash and how to fix them quickly and effectively.
What Causes Apps to Crash?
Before fixing the problem, it’s important to understand the common causes:
- Outdated apps or operating system
- Insufficient storage space
- Too many background processes
- Corrupted app data or cache
- Compatibility issues
- Software bugs or glitches
1. Restart Your Smartphone
Why It Works
A simple restart clears temporary glitches and frees up memory.

This quick fix solves many minor app issues instantly.
2. Update the App
The Problem
Outdated apps often contain bugs that cause crashes.
The Solution
- Open the App Store (iPhone) or Google Play Store (Samsung)

Keeping apps updated ensures better performance and compatibility.
3. Update Your Phone’s Software
Why It Matters
Operating system updates fix bugs and improve app stability.
Steps

What Happens
Corrupted cache files can cause apps to crash frequently.
How to Fix
- Go to Settings > Apps

- If needed, tap Clear Data (this resets the app)
5. Free Up Storage Space
Why It’s Important
Apps need enough storage to run smoothly.
Quick Fix

- Remove old photos and videos
- Clear downloads and temporary files
Aim to keep at least 15–20% of storage free.
6. Force Stop the App
When to Use It
If an app freezes or behaves abnormally.
Steps
- Go to Settings > Apps
- Select the app
- Tap Force Stop
Then reopen the app to see if the issue is resolved.
7. Reinstall the App
Why This Works
Reinstalling removes corrupted files and installs a fresh version.
How to Do It

8. Check App Permissions
The Issue
Apps may crash if required permissions are denied.
Solution

9. Disable Battery Optimization for Important Apps
Why It Matters
Aggressive battery-saving settings can limit app functionality.
Fix
