Before giving the phone to the children, make these settings in it
Now-a-days, children like to play with those things more than toys, which they see with the elders, now in simple words, if your children insist on taking the phone as soon as they see it, then it is not surprising, like this I am most afraid that they do not break the phone, do not call any unknown person or delete your important data, photos or files.
It is a bit difficult to always keep the phone hidden from their sight, but one way to deal with this problem is to use Parental Control. By the way, this feature is in all smartphones, for this there is no need to install any money or app, although there are many apps in Google Play Store for this.
Which can be used at that time if this feature is not provided in your phone. Let me tell you, if your phone has an OS version of Android 4.2 or above, then you will get the option of Parental Control in the phone's settings.
Create new user account First of all, a new user account has to be created in the phone, which is quite easy to create, that is, a new account which you can set up according to your child. For this, go to Settings>user>Add User>Profile of the phone and create a Google account.
what to fill in the account If you want, you can create an account in the name of your child, such as his name, age. With this Alternative Mail option (https://accounts.google.com/signup) I can write my mail id so that I can keep track of all its activities.
play store settings Apart from this, you can also secure the phone by making some settings in the play-store given in your phone, for this , first open the Google Play Store and like on the left, three lines have been given, by clicking in it, go to the setting option and click on Parental Turn on the Controls option.
Set PIN in Google Play Store After this, you will have to setup the PIN so that if you want to change the parental setting in the future, then change it. After this, if any phone wants to download an app from the Google Play Store, then for this he will have to enter the PIN.
