Samsung provide best ui in smartphone would. But we don't have default Internet Speed meter and default app lock. We need to use 3rd party apps for this feature. We feel risky for using this 3dr party apps. If Samsung provide this features, it will more helpful for Samsung users. Samsung provide knox security, but sometimes we need to use some apps out of secure folder. Then we must have to use 3dr party app lock. Samsung provide "S secure". But any body can uninstall "S Secure" any time, so we can't trust "S Secure". For more security, we need Default app lock and Internet Speed meter.
I agree with internet speed meter. But it is not a big issue. Why you need app lock? Because you want to secure your apps right? Samsung has already provided secure folder in which you can install the app and use it with high level knox security. No body other can see your data. Use secure folder it is the best than other 3rd party app lock apps with full of ads.
