You update an app from Play Store.
After updating, the app starts crashing, freezing, or refuses to open. Before the update, everything worked fine.
This is very common—and it doesn't mean your phone is broken. This article explains exactly why apps stop working after updates, in simple terms.
First Truth: Updates Change the App's Brain
An app update is not just a design change.
It often changes:
- How the app talks to servers
- How it stores data on your phone
- How it interacts with your phone's system
If even one part fails, the app may stop working.
Reason 1: Bugs Introduced in the Update
Even after testing, developers cannot catch every issue.
Some bugs only appear on certain phones or Android versions.
This is why an app may work on one phone but crash on another.
Reason 2: App and Server Mismatch
Most apps depend on servers.
After an update:
The app expects new server responses
If servers are not updated correctly, the app may fail.

Reason 3: Old Cache Data Conflicts
Apps store temporary files called cache.
Cache = Short-Term Memory
After an update, old memory can confuse the new app version.
This can cause:
- App crashes
- Blank screens
- Login issues
Reason 4: Phone Software Compatibility
Apps rely on your phone's operating system.
Older Android or iOS versions may not support new app features.
This mismatch can stop the app from running properly.
Reason 5: Permission Reset After Update
Sometimes updates reset app permissions.
If the app loses access to:
- Storage
- Camera
- Network
It may stop functioning until permissions are re-enabled.
What You Can Do When an App Stops Working
Restart your phone
Clear app cache (not data first)
Update your phone software
Wait for a bug-fix update
Simple Summary
Updates change core logic
Not just design.
Bugs are common
No update is perfect.
Servers matter
Apps depend on them.
Cache causes conflicts
Old data breaks new logic.
