yes it should be getting as it has only received one of the two software upgrades it will be getting however dont expect it to have all the features that the S20 or S10 series have with One UI 3. As it's a more toned down for the budget devices. Android 11 is the last Android OS update the A20e will be receiving. It will still receive Security updates for some years to come.
it could yes but more than likely (90%) it will not. The reason to this is that Samsung's update policy states that their phones only receive 2 Android OS updates. This policy has now changed to 3 OS updates with the galaxy S10, note 10, S20. So these devices will reieve 3 Updates. With the A20e being a budget device it will not be able to run anymore than android 12 even the S9 isn't getting Android 11 as it has already had 2 updates
