Can someone explain this to me. I've used nothing but Android for a few years now and all of them have become laggy.

First I got a Cheap phone under $300. This was my first smartphone. It was great until a few months passed. I asked why, they said get something more expensive.

Then I get the htc one x when it comes out. They say it's powerful and A Quad core! Same thing...lag

Note 3...same thing

Note 4... Wtf. I installed cm12 on the Note 4 even. It got faster for a while and then back to normal.

Android is plain traaaaaaash.
