Samsung Messages App – Required Configuration for Test Validation

To ensure SMS and MMS features function correctly during testing, configure the Samsung Messages app as follows:

📩 Enable MMS Auto Download (Normal + Roaming)

  1. Open the Samsung Messages app.
  2. Tap the three-dot menu (⋮) ➔ Settings ➔ Multimedia messages.
  3. Enable both of the following: - Auto retrieve – ON
    - Roaming auto retrieve – ON

🕒 Set Time Format to 24-Hour

⚠️ Although this setting is system-level, it's critical for message timestamp consistency within the app.

  1. Open the Samsung Messages app.
  2. Tap the three-dot menu (⋮) ➔ Settings ➔ Check for Date & Time Format (if available).
    - If available, set it to 24-hour format.
    - If not visible, set this under: Device Settings ➔ General management ➔ Date and time ➔ Use 24-hour format – ON.

💬 Disable RCS / Chat Features (If Available)

Some Samsung devices support RCS (Rich Communication Services) via the Samsung Messages app. This must be disabled for compatibility with basic SMS/MMS testing.

To disable RCS:

  1. Open the Samsung Messages app.
  2. Tap the three-dot menu (⋮) ➔ Settings ➔ Chat settings.
  3. If Chat features is visible: - Toggle Chat features → OFF. - Ensure Default messaging type is SMS/MMS (not Chat).

🔍 If the Chat settings menu does not exist, RCS is not active on the device—no further action is needed.
