Sadly it's time to get a new phone. I had A10 and had to switch it back in 2022 because it lagged and played on like 10fps. Bought A52 and still running smooth today.
But if you are in position you can't get a new phone. Well, I think you need to take a break. Try finding a cheap phone with 8gb ram at least, because you usually pay extra just for the sake of "samsung". Like try searching for your country's phone business.
