Updates in the Galaxy A series
Samsung has prepared updates for three smartphones. From Han and Richard, we hear that the Samsung Galaxy A37, A57 and A55 will be updated. In the case of the first two models, the latest devices in the A-series, it involves an additional interim update. In this, the device will continue to feature April's security update, but there are several stability improvements. Exactly which adjustments are being made is not known.

A newer update is ready for the Samsung Galaxy A55. That smartphone will receive the May security update. This along with patches from Samsung itself.
As soon as you can install the update on your device, you will get a notification of this. Optionally, you can also check for software updates manually via settings.
