When the File Manager on your OnePlus 15 keeps crashing, even simple tasks like opening folders or moving files become frustrating. The app may close suddenly, freeze, or refuse to open at all. In most cases, this problem is caused by corrupted app data, storage issues, or temporary system glitches, and you can fix it without resetting your phone.
Why the OnePlus 15 File Manager Keeps Crashing
- Corrupted cache or app data inside the File Manager.
- Low internal storage affecting system apps.
- A recent system or app update that did not install properly.
- Conflicts with third party file manager apps.
- Temporary system processes causing instability.
Clear File Manager Cache and Data
The File Manager stores temporary files to load folders faster. When this cache becomes corrupted, the app may crash repeatedly, especially when opening large directories.
Open Settings, and then tap Apps.
Tap App management and select File Manager.
Tap Storage usage, then tap Clear cache and Clear data.
Restart the Phone
Restarting refreshes background services that the File Manager depends on. This step often fixes crashes caused by stuck system processes or memory conflicts.
Swipe down from the top of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
Wait for the phone to fully boot, then open File Manager again.
Check Available Storage Space
When internal storage is almost full, system apps may stop working properly. File Manager is especially sensitive to low storage conditions.
Open Settings, and then tap Storage.
Review available space and delete unused files or apps if storage is low.
Restart the phone after freeing space to stabilize performance.
Disable or Remove Other File Manager Apps
Third party file manager apps can interfere with the built in File Manager. This can cause crashes when both apps try to access storage at the same time.
Open Settings, and then tap Apps.
Find any third party file manager app and tap it.
Tap Disable or Uninstall, then test the built in File Manager.
Update System Software
Software bugs can cause core apps to crash, especially after major updates. Installing the latest update ensures system stability and bug fixes.
Open Settings, and then tap About device.
Tap Software update and install any available updates.
Restart the phone once the update is complete.
Reset App Preferences
Resetting app preferences restores default permissions and background behavior. This can fix crashes caused by incorrect permission settings.
Open Settings, and then tap Apps.
Tap App management, then tap Reset app preferences.
Confirm the reset and reopen File Manager.
File Manager crashes on the OnePlus 15 are usually caused by minor software issues rather than serious hardware problems. Once cache files are cleared and storage is stabilized, the app should work normally again.
FAQs
Why does File Manager crash when I open large folders?
Large folders require more memory to load. If storage is nearly full or cache data is corrupted, the app may crash while trying to display files.
Will clearing File Manager data delete my files?
No. Clearing app data only resets the File Manager app settings. Your personal files remain untouched.
Should I factory reset my OnePlus 15 if File Manager keeps crashing?
A factory reset is rarely needed. Most crashes are resolved by clearing cache, freeing storage, or updating the system.
