Recently I searched for Galaxy A71 New test firmware. But I don't know why the baseband version is showing same. It's showing old October security patch information and the date is of today. I think the app doesn't give real update information. So don't believe in this 3rd party app.
The app is third party but is only for samsung users. Its function simple, it just redirect you to the samsung server of test firmware. Sometimes due to server problem the app also get some problems to show you the informations.
