I recently got my Galaxy Tab Pro 8.4 (SM-T325) from HK, and it came with the latest firmware already (T325XXU1ANB6). I've watched a youtube video before, demonstrating how to activate mutiple users on the Tab Pro 8.4. However, I can't find it in the settings at all (Settings 》General). Has this feature been removed in the latest firmware update (and might possibly be region-dependent)?
