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. 

Did you know that there are many ways to work easier on your Samsung phone?
You can turn on many different shortcuts that can help you a lot.
The ones I really enjoy using are the "double tap the home button for camera (Quick Launch Camera)" and the "One handed mode."
The quick launch camera allows me to access my camera quickly so I can capture those important moments and the one handed mode helps me when im using
my phone in one hand.
There other others shortcuts that you can turn on to meet your prefrences.
If you want to find these shortcuts go to Settings - Advanced Settings and they will be in that page.

Well my experience with the Samsung is that its very convenient to use the device. At the early stages it is modeled as very fast and most of the settings are similar to that of the iPhone. If someone is preferring to take the iPhone, but has relatively low budget, I would prefer Samsung also as the best smart phone. The cameras in the back and the front are both clear with multi settings. Well the good thing is, it is water resistant and the price is much more affordable with reasonable costs. It has become the best choice for the many people because of easy handling and clear boxes. 

When there is a poor internet connection it’ll be challenging to do FaceTime with video streaming. If you just want to talk without video, you can do audio only call using FaceTime.  There are multiple ways to make an audio call using FaceTime.

Open FaceTime App and tab the info button at the right to go the contact details screen. In this screen go down to FaceTime filed. Next to FaceTime use the phone button to make audio only calls. Same screen can be reached directly by tapping a contact name in the contact App. On top of the iMessage conversation under the name you’ll find the option to select FaceTime audio by tapping the audio (phone) button. 

Since FaceTime VoIP calls using WiFi, it’ll not be a regular call using your cellular network. It could be a good alternative to other VoIP solutions to call your friends and family if they have iOS devices with WiFi connection. Also, voice quality should be better with audio only calls compare to using with video streaming since it uses less bandwidth.
