Samsung has started development on Android 10 for the Galaxy A50 and A40. No betas are planned for either of the devices, though.
It took the company less than two months after it started work on Android 10 for the Galaxy M20 and M30 to release the official update.Going by this, the Galaxy A50 and A40 should get the official Android 10 update by March 2020.
Remember that the M20 and M30 received a largely stripped Android 10, while A50 and A40 expected to pack most of the features the Android 10-based One UI 2.0 brings. So it may take a little longer for the official update to arrive.
