Sony Mobile says it's confirmed an issue with some Xperia S phones that result in the display showing a yellowish hue at increased temperatures, following reports from disgruntled Xperia S users over the past month. In a statement, the manufacturer said it'd "identified that the display on a limited number of Xperia S smartphones may show a slight yellow tint if exposed to temperatures above 40 degrees Celsius."
Sony says Xperia S owners with affected hardware should contact customer support to have the issue remedied "at no cost", which we presume involves Sony replacing faulty devices.
Along with its 12MP camera, the Xperia S's 1280x720 "Reality Display"-branded screen is one of its most noteworthy features. Any hardware defect in a flagship product is sure to be a source of embarrassment, but it's good to see Sony actively addressing this problem and replacing affected handsets. (Especially since they're required to by law in the UK and EU.)
We didn't notice any heat-related problems with the phone when reviewed it, but if you have, be sure to shout out in the comments.
