Hi! I see you’re experiencing jittery performance when using the Metro app on your Samsung Galaxy running Android 15. Just to clarify, when you say "jittery," do you mean pages or scrolling feels choppy or delayed? Also, is this happening only in the Metro app or in other apps too?

In the meantime, here are some step-by-step fixes tailored for your Samsung device with Android 15 that often help with similar performance issues:

1. Clear App Cache and Data:
- Go to Settings > Apps > Metro app.
- Tap Storage > Clear cache. If issues persist, try Clear data (note: this may reset app settings or require login again).

2. Restart Your Device:
- Simply rebooting can clear temporary glitches affecting performance.

3. Check for App Updates:
- Open Google Play Store, search for Metro app, and update it if available.

4. Check for System Updates:
- Go to Settings > Software update > Download and install to ensure your phone and Android OS are fully updated.

5. Disable or Limit Background Apps:
- If many apps are running in the background, they can slow down your device. Close or restrict apps you’re not using.

6. Switch Navigation Mode Temporarily:
- Some users noticed that switching to button navigation and back to gesture navigation helped smooth performance on Android 15.
- Go to Settings > Display > Navigation bar, switch to button navigation, restart your device, then switch back.

7. Clear System Cache Partition:
- This is a bit more advanced but can be done by:
- Power off your phone.
- Press and hold Volume Up + Side key until the Samsung logo appears.
- Use volume buttons to navigate to Wipe cache partition and confirm with power button.
- Reboot the device.

If after these your Metro app pages are still jittery, it might be linked to app optimization hiccups with Android 15. If you like, I can help escalate or guide you through additional checks.

Does this help so far? Any of these steps you’ve already tried or more symptoms you want to share?

I've done everything you suggested, the problem is just with the Metro app.

Thanks for confirming that the jittery issue is only with the Metro app and that you’ve already tried the common fixes. Let's try a few deeper steps that might help resolve app-specific glitches:

1. Force Stop the Metro App:
- Go to Settings > Apps > Metro app.
- Tap Force Stop to completely close it. Then reopen the app to see if performance improves.

2. Reinstall the Metro App:
- Uninstall the app fully from your device.
- Restart your phone.
- Then reinstall the latest version of the Metro app from the Google Play Store. This can fix any corrupted files or updates that didn’t install correctly.

3. Check App Permissions:
- Sometimes missing permissions can cause apps to behave oddly.
- Go to Settings > Apps > Metro app > Permissions.
- Ensure all necessary permissions (like storage, network) are allowed.

4. Use a Different Network (Wi-Fi vs Mobile Data):
- Try switching between Wi-Fi and mobile data.
- Sometimes network instability can cause app lag or jitteriness.

5. Check for Account Issues:
- Log in to your Metro online account via browser to verify your account is in good standing and there are no alerts.
- If the app is unable to sync account data properly, that may cause sluggishness.

If all these steps still don’t resolve the issue, this could be a compatibility issue with your device or a bug in the app version currently on Android 15. At that point, I recommend contacting Metro app support directly via [email protected] to report the problem for further investigation. Meanwhile, you can also use Metro’s mobile web portal as a temporary alternative.

Would you like me to help you with the reinstall process or checking permissions step-by-step? How does this sound?
