User comments

Here are some links to web pages where mobile camera users complain about the color shading issue. Most people describe the effect as a pink/blue/green spot. These are only a small selection of typical examples, as the complaint is very widespread. Listing all the phones and complaints would require several pages. Note that all these phones use per-unit calibration (with or without a hybrid filter).

Sony Ericsson Xperia X2

From i2mob.com: « However we noticed that the Sony Ericsson XPERIA X2 is having the pink spot issue that we know from the HTC HD2 camera.
