Communication blocks often originate from text message interactions. Consequently, Samsung also allows users to manage their block list directly from the Messages app. To do this, the user opens the messaging application and accesses the settings menu (again via the three dots). Under the "Spam and blocked" or "Block messages" section, a list of blocked numbers is available. From here, the process mirrors that of the Phone app; the user can select the number and choose to remove it from the blocked list. This is particularly useful for users who frequently deal with SMS spam and manage their communications primarily through text.
