I think Samsung is delivering programming refreshes which slow your gadget after some time and make it slack and hang so you quit utilizing your old telephone and purchase another one from them.
I additionally have two Samsung telephones one I bought before 1 year 9 months and the other before 7 months. The first slacks a bit and I think it is on the grounds that I refreshed it from android 9 to android 10. The other one has no hang or slack issue perhaps on the grounds that I haven't refreshed it. The bygone one is A20 and the new is M11.
