From experience, I think that Snapchat is just fine for kids and parents to use. I got Snapchat when I was 11 years old, and it is fine to use, if you use it respectfully. Your “Story” can contain all the snaps that you want your friends to see. You can also change on who can see your snaps.
When you call a dead phone does it ring?
Answer: A: With a dead battery it should not ring but it should go to voicemail directly.
