Sony has confirmed that its Xperia S can develop a yellow screen tint if the handset gets too hot.
The platform holder said that the problem is limited to a small number of users and has now been addressed.
"Sony Mobile Communications has 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," a company spokesperson told CNET.
Sony pledged to replace devices affected by the problem "at no cost to the consumer", and offered assurances that alterations to the product's manufacturing process have laid the issue to rest.
The Xperia S smartphone boasts a 4.3-inch 1280x720p HD LCD touch-screen display, a 1.5Ghz dual-core processor, 1GB of RAM and a 12-megapixel camera capable of recording 1080p HD video.
Sony launched the handset in the UK and various other territories in March.
