What is the package name for the default Samsung Gallery App? Deleted it while debloating my Samsung Galaxy S21 Ultra. I am unable to install it via the Samsung store. Thank you in advance!
The default package name of the Samsung Gallery app (at least on my Samsung device here) is
com.sec.android.gallery3d
