And why didn't they catch that problem with Lithium ion batteries before they ever shipped those phones, hard to understand how that got so out of control before they realized this? With all the knowledge about overcharging and other issues with those batteries I can't comprehend how this ever happened. I'm sure other phones have some percentage of battery failures but these were known issues for so long now.
 
Reading some of the analysis there was such a culture of fear instilled by the management that no one dared put their hand up. Wouldn't be the first time this has happened, and certainly won't be last. Even NASA has suffered from this. But still going to hurt them for a very long time!
 
Kindhornman, why be so critical? I have heard about things like this for decades. I even own a electrical 'cartridge demagnetizer' myself. Apparently, it effects, not the primary magnet, but an added magnetic 'slug' that is added to the cartridge that increases its output. It is not supposed to be magnetized, but it does, over time, probably due to the closeness to the primary magnet.
 
The Samsung battery scandal is amazing. I was flying across the east coast today, and hearing announcements at the gates in in the airplanes that the Samsung was not allowed on board, well, that's gotta hurt. I don't remember ever hearing anything like that before.
 
John,
Your talking about an actual demagnetizer, not using a vinyl record to turn the stylus into some sort of demagnetization device. Now how you can selectively demagnetize the slug of metal you are talking about in a cartridge without affecting a magnet in the same device I would like to know? Perhaps the permanence of the real magnet material is strong enough that your demagnetizer isn't strong enough to affect those magnets?

Scott,
If I didn't challenge these statements someone else surely would in this thread I suppose. Curious minds want to hear the justifications for some of these strange statements.
