how to put restrictions on your android devices:

1. On the device you want parental controls on, open the Play Store app

2. In the top left corner, tap Menu Settings Parental controls

3. Turn on Parental controls

4. Create a PIN. This prevents people who don't know the PIN from changing your parental control settings. If you're setting up parental controls on your child's device, choose a PIN they don't already know

5. Tap the type of content you want to filter

6. Choose how to filter or restrict access
