Samsung's role as both supplier and competitor of some of the biggest names in the smartphone industry can make most of its clients wary of conducting further business with them. A good example is a report from Apple Insider that says Nokia may also start veering away from Samsung because their technology can get compromised with continued business with the Korean giant.
Furthermore, the source also claims that instead of shipping next-generation components to their clients, Samsung typically cancels and use the components for themselves. Furthermore, the source states that Samsung has stolen an important specialized design for OLED from the Finnish giant, Nokia.
When you see a Samsung (certain specialized new design for) OLED phone as you surely will, you are looking at something that was stolen from Nokia.
Just recently, Apple won $1B against a lawsuit filed against Samsung for infringing on intellectual property rights. With the kinds of allegations that Samsung is facing from two major companies, it will be hard for them to come up with something new without much scrutiny.
