The Android 10  update is finally making its way to the Samsung Galaxy Fold.  One would expect that a $2,000 device would get software updates on priority, but such is life. To be fair, the Galaxy Fold was notably absent from Samsung's Android 10 roadmap, so we can't really blame the company too much. Besides, the past few weeks have been disastrous, so it's best not to dwell on it.

The Galaxy Fold's Android 10 update has build number F900FXXU3BTCD and includes the March 2020 Android security patch (via Sammobile). It is only available for the 4G version of the foldable in France, and we can expect a wider rollout to commence in the coming weeks. There's no word about when the 5G version will get the update yet. Chances are, it'll take a while, considering that Samsung usually updates its 4G phones first.
