In what way are Samsung not a reliable supplier? Doesn't Samsung invest in the USA and employ Americans to make their processors for Apple? Why are so many people ecstatic at the idea Samsung might loose all of that business with a possible negative impact on jobs and investment in the US?
Have you used an LG G3 in real life? Anandtech have. In their review of the G3:And from their mini review of the G2:The G2 has 36% more volume than the 6 but has 65% greater battery capacity. It manages a 5.2" screen in a body that is the same length as the 6 and is only 4mm wider and 2mm thicker.
Thinner bezels, a much bigger battery sounds like last years LG G2. The new iPhones are really nice. Apple are going to sell a lot in prosperous markets. I would imagine not a few people at Samsung are feeling a bit nervous and quesy right now.
