I am big fan of Nokia windows phone and using other lumia models for more than a year now. This is true that Lumia 535 has a touch issue. I felt it when I used this mobile for 5 minutes in Nokia center. But Now Microsoft has come up with a fix, which will be available after 27 Dec 2014 to update. Soon I am going to buy this mobile too. I am giving 5 star because all features are best at this price, much better than android mobiles, with great hardware.
Microsoft had recently acknowledged the issue with weak touch-screen sensitivity on its Lumia 535 smartphone recently and had assured that an update to resolve the issue will be rolled out before December 27th. Acting quicker than expected, the company has now started seeding the update in select markets around the world.
The new update is rolling out with the Lumia Denim update for the Lumia 535 smartphone. Apart from the much needed touch screen performance improvement, the update also brings Cortana to more markets and the ability to switch mobile data on or off directly from the action center. You will also be schedule your phone updates now to a time of your preference. Stability and performance improvements are included too, as is the norm with almost any new software updates
