Yes bro, device lagging is a issue after 2-3 years with Samsung. Happens with high end models too. Let's see how this one goes.
Btw, the iPad i exchanged was a 2014 model and running with latest iOS. So i am well aware how Apple never abandon their very old models too.
Bro one of my friend just bought Samsung M20 just one month ago and he complained that his device got hanging issues now and then. Poor chap. So that’s why I quote hand issue to you.
And I also purchased old iPhone 7 with bill of ₹40k on ₹28k and it’s was just 15 days old from purchased bill date. I like apple because of it’s regular os and security updates and value for money. After using apple device one can get enough money while reselling it.
