The Lumia 535 is a very popular device but has always been troubled by touch screen issues. Microsoft has already pushed out an update specifically to address this issue, which worked for many, but left some with continuing problems.
Now WindowsMania.pl reports that there is another update available on Microsoft’s servers, again to address the screen issues.
Interestingly the firmware is also accompanies by a slightly updated version of Windows Phone 8.1, which is now at build 14234, up from 14226.
The firmware is currently available via the Lumia Recovery Tool, but we assume Microsoft will eventually push it out to over the air also.
