1. Live network speed indicator is not literally feasible as it doesn't really provide real-time data... it's something that is related to Chinese phones. 2. The secure folder provides the app lock feature in Samsung phones, which is quite amazing. Try it please. 3. Multiple user mode is already present. I have a Galaxy tab s7+ which has one ui 5.1.1 and it already has multiple user mode and moreover it's not really required in personal phones as you don't give it to many people to use them. 4. This feature should definitely be released with the next beta updates.
