I think after your new back to back launches like A50s M30s Samsung have forgotten about their older devices. I have A30 and still there is patch of July and version is out of date. On the other hand Galaxy M30s is cheaper than my device still there ...
samsung and other companies only focusing on their online mobiles.But they also have to keep this thing in mind that their best selling mobiles of this year like a50 a30 and a10 all are offline mobiles.
