I've heard advice given like this: Don't buy an appliance from a brand that makes smartphones.
That being said, Samsung, as a Chaebol/conglomerate, can suck and some things and be great at others, simply because its various divisions are very loosely related to each other. In this case, I've heard bad things about Samsung appliances and better things about their display and DRAM production.
Wait until you find Samsung and Bosch components in your car.
Bosch and Samsung are conglomerates and make much more than even the list you've generated. Especially hvac and mechanical. Including non electronic.
