Spots aren't the only issues discussed on this thread, read back through it. Pg 6 & 8 in particular IIRC are pretty enlightening, but best to read it all. IIRC it was already agreed that the black spots were probably a characteristic of AMOLED/production. Unless someone beats me to it.... I may do a summary of it all soon, & then get the OP to update the 1st post. It's getting too tedious, all the info/observations are too disjointed.
