Lumia 535 display is found to be suffering from touch issues
An update is being prepared to resolve the problem
Microsoft has acknowledged a screen sensitive problem of the Lumia 535. Users have reported that the screen is way too sensitive which affects the accurate fingers tracking in multi-touch. A video by WinPhoneViet demonstrates this inaccurate finger tracking.
This means that you could have problems while using Word Flow keyboard and other elements when multi-touch is used.
Microsoft is aware and is working on an update to fix the sensitivity problems of the Lumia 535. Meanwhile, you can try a temporary solution. Go to Settings -> Ease of Access, and turn off the Screen Magnifier. This could improve the display to some degree.
Microsoft Lumia 535 is a low-cost smartphone with a 5-inch screen, quad-core Snapdragon 200 processor with 1 GB of RAM, and two 5-megapixel cameras. The Windows Phone is being sold for around 104- 130 EUR in selected European and Asian countries.
Meanwhile, new cheap Lumia smartphones have been registered in the FCC certification website. A picture leaked from China shows a 4-inch device which is believed to be the Lumia 330, while the international version of the same device could launch as Lumia 435. These new Lumia series (below 5xx) will replace the discontinued Nokia X and Nokia Asha. Microsoft is expected to present Windows 10 for PCs and phones at an event on January 21, where we can also see new smartphones.
