Brew doctor complains about 2 unbrewed dylibs (possibly remnants from Samsung Sidesync) I've just found that brew doctor gives me the following error :

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:
    /usr/local/lib/LibSideSyncOSX9.dylib
    /usr/local/lib/ss_conn_lib.dylib


I am suspected that these are remnants of Samsung Sidesync program that I tried to use recently but it never worked, so I uninstalled it (using iTrash).
Should I manually remove those two libraries or not(one of them is 1.7mb)?
Thank you.
Yes you should remove them. Package managers will complain if there are files installed in the area they manage. So with Homebrew only Homebrew installed files should be in /usr/local

In this case I would guess from the names the first is definitely from Sidesync but the second could also be used by others
