Samsung Electronics is only a subsidiary of Samsung Group which makes all those things. Samsung Electronics profits were $9.6 but that includes TVs and their semiconductor division. The actual mobile division had $6.3 in profits (about 20% growth from same time last year).
Samsung's profits are up mainly because of chips which makes sense when they're manufacturing Apple's chips (and Apple's iPhone sales are up significantly). Samsung's growth in high-end phone sales is slowing down.
No the $6.3B is from the mobile division alone. Their chip sales also saw profits of about $1.9B which is double than same time last year, but the phone sales are still their #1 business.
Yes I know, my comment doesn't dispute that. Phones are the biggest piece, but increasingly that's coming from low-end phones, the growth in high-end phones is slipping.
Also, a significant share of Apple's revenue (and profit) is in the Q4 holiday season. Far more so on a percentage basis than Samsung. So I'm not really sure what the OP was getting at? A more important comparison I think is margin.
