On my list:

Produce a well-specified camera/camera range that equals (if not exceeds) the performance of its direct competition.

Ensure that the camera is well-made, reliable and durable; fix any problems quickly and efficiently.

Make the camera compatible with another system (eg via the lens mount) so that customers have a real choice in building a 'system'.

Nurture "product innovation", but keep it relevant (to customers' needs) and under control: avoid gimmickry.

Price the camera competitively, and do not overcharge for lenses and accessories.

Market the camera with style and confidence to the most relevant customer-base and find some strong, high profile product champions to 'carry' the marketing (a la David Bailey style c.1980s).

Make pre-sales and after-sales customer service tangible and user-accessible.

Even some established brands have failed to achieve some of those points from time to time most - notably for me Sigma and Leica. On paper, Samsung may not be far from achieving most of those 'aims': but any minor foul-up can be perceived by potential customers as a big setback.
