Kids Space in OPPO Smartphone is one of the best feature. This facility helps those who are using OPPO Smartphone and also sometimes using their kids. You can avoid all the irregularities when your kids using phone without their technical knowledge.  Kids Space is a locked down version of the OPPO operating system that only has access to apps you authorized and can't be excited without a PIN. As the name suggest, it is a safe space that lets you hand over your phone to your child without worrying about them accidentally emailing your entire contact list. In addition to locking down which apps your children can access on your phone, Kids Space also lets you restrict the time they can spend using them. Navigation of Kids Space Set Up is :   Open Settings >> Tap on Security >> Tap on Kids Space.  Here you can set the Duration of Each Use, Allowed Apps, and whether or not your child can use mobile data when they're in Kids Space. 
        You can use the Kids Space settings pane to launch Kids Space, but you can also add a shortcut to the control center if you need it regularly.
