Sony acknowledge display issue with the Xperia S

A few owners of the Sony Xperia S has discovered that the display on the smartphone will get a yellow tint if internal temperatures reaches 40 degrees Celsius. The phone does not reach this high temperatures with normal usage but heavily gaming and CPU intensive apps might cause internal temperatures to increase to over 40 degrees Celsius / 104 Fahrenheit.

This is a hardware defect and Sony has told customers to direct their concerns to the local service center. Faulty displays were shipped with the first batch of Xperia S, and the problem has been solved for phones produced now. Depending on availability and spare parts, customers with affected displays will get it replaced or exchanged completely with a new handset.

Sony has released the following statement about the issue:

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. This is limited to a small number of units and the cause of this has been corrected. Any consumer observing this slight yellow tint on the display of their Xperia S is welcome to contact their local customer service centre and Sony Mobile Communications will resolve this at no cost to the consumer.

The yellow tint is very visible when the display is showing white pixels, but the same fault are visible on black or darker pixels as well. Xperia S owners will then notice a gradient transition to lighter pixels. On our review unit, the fault is mostly visible to the top right corner of the display, and close to the bottom just above the home key.

This is a photo of the Xperia S display just seconds after running a stress test app for 10 minutes. We have modified the image and increased the yellow saturation so that you can see exactly where to look for this hardware defect.
