I have been using Lumia 535 for 2 years only. I must have to say that I am fully satisfied with this Cellphone.
At the first time, I was little disappointed about touch screen and heating issue. But as the software was automatically updated, all the problems have gone away.
The sensibility of touch screen is awesome. The phone is always cool without any any heating issue. The sound is perfect.
Now I am a proud owner of Lumia 535.
