Accuracy results ar more or less the same as Hariainm's. Dead pixel test works a charm luckily don't have any. I've said it before but i'll say it again this is fast becoming a must have application. I think Nokia should incorporate it into future release
One thing I am working on and I may need your help Noob, is extracting information from this to a remote server/another phone.
Basically running it in back ground to export as much information in case of the phone getting lost/stolen over ssh or via intercepted txt message.
If thats ok with you Noob.
