File systems are extremely fickle things requiring the utmost attention to detail and quality. There is an impedance mismatch between that and most people's image of Samsung-produced software.
Samsung Mobile has a reputation for making poor quality Android UIs (though they also have a few other OS projects going on; the EFL one and something else).
Also, Samsung-LSI generally makes better SoCs than the other guys (normally the bus works properly, etc). If you wanted to pick on them in a constructive way then you could say "I hope they clean up their mess in arch/arm..."
I am saying they will be working against a strong "Samsung is good at hardware, but not at software" reputation.
I love Android, and I like some of Samsung's hardware but I wish they'd shut their whole software division down and just put stock android on their phones and tablets. Stop writing code, and stop designing your custom UI, because you SUCK at this job.
