How to Fix Common App Problems (Android & iPhone) – Step by Step

- Switch between Wi-Fi and Mobile Data.
- Restart your router if Wi-Fi is slow.
- Test with another app (YouTube, Chrome).

4️⃣ Fix 4: Restart Your Phone
This resets temporary system bugs.

- On iPhone: Press volume up → volume down → hold power until Apple logo appears
5️⃣ Fix 5: Update the App
Many crashes happen because the app version is outdated.
- Android: Open Play Store → Search App → Update
- iPhone: Open App Store → Updates → Update All
6️⃣ Fix 6: Reinstall the App
This is the most effective fix based on user reports.
- Delete the app
- Restart your phone
- Install it again from the Play Store or App Store
This resets corrupted files without affecting your account.
7️⃣ Fix 7: Check App Permissions
Apps may not load or crash if permissions (Camera, Storage, Location) are blocked.
Android:
Settings → Apps → [App] → Permissions
iPhone:
Settings → [App Name] → Enable required permissions
8️⃣ Fix 8: Check for System Update
Old system versions cause many app errors.
- Android: Settings → System → Software Update
- iPhone: Settings → General → Software Update
Alternative Methods (If the App Still Does Not Work)
Try these extra solutions:
Use the Web Version (Browser Login)
Many apps like Facebook, Instagram, Gmail, and TikTok work fine on the browser.
Try a Different Login Method
If SMS code isn’t arriving:
- Use email login
- Use backup codes

Check for Server Outages
Search “[App Name] server status]” or check Downdetector.
Log Out and Log Back In
Fixes account session problems.

Or use web support pages:
Examples (based on official help centers):
- Instagram Help Center
- Facebook Support Inbox

FAQs:
Q. Why is my app not opening on Android or iPhone?
A. An app may fail to open due to cached data problems, an outdated app version, low device storage, poor internet connection, or a temporary server outage. Try force-closing the app, clearing the cache (on Android), updating the app, and restarting your phone. Reinstalling the app often resolves the issue.
Q. Why is the app not sending the verification code?
A. Apps usually fail to send verification codes because of network issues, carrier delays, or too many attempts in a short time. Wait for 30–60 seconds, restart your phone, try a different phone number, or select the “Try another method” option. Email verification often works faster.
Q. Can I recover an account without an email or phone number?
A. In many cases, yes. Some apps allow account recovery using a username, a trusted device, identity verification, or backup codes. If none of these are available, you’ll need to contact the app’s support team and provide proof of account ownership.
Q. Why does my app keep crashing after an update?
A. This usually happens when the new app version conflicts with old cache files or when your device software is outdated. Clearing the app cache (on Android), restarting your phone, and updating your device’s system software can fix the problem.
