Can anyone please tell me what the Galaxy font is?

Thanks

Sharp Sans No. 1  Suggested by donshottype 

I believe this is a customised version of Neo Sans. Look here: http://www.dafont.com/forum/read/88174/looks-like-samsung-font

Samsung uses Samsung Sharp Sans, a custom version of Sharp Sans No. 1.
Samsung Sharp Sans is not offered to the public.
The link is to the standard retail version Sharp Sans No. 1
