The problem he is having more than likely won't go away as shown with the latest updates from even overseas. If wants those problems solved and the only way for them to be solved is for Samsung to issue updates to fix them. That's the ultimate truth.
FYI - I no longer buy Samsung devices and haven't since the released to the Behold 2. My Boss may buy them for me for work related things, but I tell everyone at work that Samsung does great marketing for mediocre devices with very poorly written code. There's still bugs on their devices since 2.2. update 1 which they themselves know about and still haven't fixed since then.
