How convenient. "Not going to attempt to cite sources"? So you have no proof to backup your claim, making your point moot & useless. You have no evidence that's not complete speculation.
Also, what reviews have you been reading? What reliable sources have addressed this in a review besides your pet goldfish?
Oh boy....
How about doing some research on your own then?
Try open the file /system/etc/gps.conf. See if you can spot something interesting under the AGPS server settings section. There are other examples, I will leave them to you to discover.
Anyway, back on topic. My phone does flicker, but I have never seen it turn white completely... Not for the lack of trying either. Flicker doesn't bother me that much, but white out would probably drive me to a return/exchange.
