Hi there! I see you're having trouble logging into the Lufthansa app on your Samsung S25, and it's showing a "Technical error." Let's see if we can get you back on track.

To start, can you tell me if you have tried clearing the app cache or reinstalling the app? Also, are you using the default browser on the phone for the login process, or have you customized it?

Meanwhile, here's a step-by-step you can try as initial troubleshooting:

1. Clear Cache and App Data:
- Go to Settings > Apps > Lufthansa app.
- Tap Storage.
- Select "Clear Cache" and then "Clear Data."
This can help eliminate any corrupted files that might cause login errors.

2. Check Default Browser:
- Sometimes, the default browser affects login via app. Some users reported issues with Chrome or Brave browsers on Android devices.
- If Chrome is your default browser, try switching to Firefox or another browser and then attempt logging in again.

3. Reinstall the Lufthansa App:
- Uninstall the app.
- Restart your phone.
- Download and install the latest version from the Google Play Store.

4. Ensure your phone’s system software and app are updated to the latest versions.

5. Check your internet connection — a stable Wi-Fi or mobile data connection is important.

If after these steps you still see the technical error, please let me know. There may be a more specific issue with the Samsung S25 and our app that we can investigate further.

Are you comfortable trying these steps now?

Login does not work on Samsung S25 - gives "Technical error" tried Henry Adams's steps w/Edge browser plus restart, app requested either stay in app (when I logged in) or open in Edge. While trying app gives same technical error and when choosing Edge, just gets stuck with spinning pinwheel of death.

Thanks for the update and for trying those steps with Edge. It sounds like the app is stuck in a loop between staying in the app and opening Edge, where the spinning pinwheel never resolves. This points to a deeper issue with the app's interaction with the browser on your Samsung S25.

From recent reports, it appears that some Android devices—including newer models like the S25—are experiencing ongoing "Technical error" login problems specifically with Lufthansa's app and Travel ID login system. The problem sometimes causes the app to stall or fail to load properly when switching to the browser for authentication1.

Given this, here is what I suggest next:

1. Try an Alternate Browser for Login:
- Since Edge is causing the spinning wheel, set another browser as the default temporarily—Firefox or Samsung Internet Browser are good options.
- Then, open the Lufthansa app and attempt login again to see if it successfully redirects and completes authentication.

2. Use Lufthansa Web Version as a Workaround:
- If the app keeps failing, log in directly at lufthansa.com via your preferred browser on the Samsung S25.
- This will let you access your booking and account until the app issue is resolved.

3. Check for App and System Updates:
- Verify that both your Samsung S25 system software and the Lufthansa app are fully updated. Sometimes pending updates contain bug fixes.

4. Report This Behavior to Lufthansa for Tracking:
- Since this appears to be a wider issue affecting some users on Samsung S25 and Android, consider sending your device details and error description to Lufthansa's mobile support at [email protected]. They can escalate for a fix.

5. Try Logging in on Another Device Temporarily:
- If you have access to another phone or tablet, try logging in there to confirm if the problem is device-specific.

If none of the above work or if you want me to help with any step, just let me know. We'll get this sorted for you as smoothly as possible.

Are you ready to try switching browsers and the web workaround?

Tried the various steps above, finally looks like logging in through the Samsung browser worked Thanks for the help

I'm glad to hear that logging in via the Samsung Internet Browser worked for you! It matches with what some users have experienced—certain browsers like Chrome or Edge sometimes cause login issues with the Lufthansa app on Android devices, while alternate browsers such as Samsung Internet or Firefox often resolve this "Technical error" problem1.

If you prefer using the app, this workaround with the Samsung browser is a good temporary solution until any pending app updates fully address compatibility with the S25 and browser login flow.

If you encounter any further issues or want help with anything else, just let me know! Are you satisfied with this solution?
