Samsung Galaxy M53 has reached its end of life, meaning that there wont be any further (official) Android updates for it. It might receive security patches, but wont get new Android operating system updates from its manufacturer. There's a lil bit chance but let's hope for the best.
No hope, Samsung won't release Android updates to it. Even S20 series also they didn't consider to extend. You have to buy new one if you want latest Android
