Many parents choose smartphones for their children's Christmas presents.
Alex Kidman, a technology journalist, said, "Smartphone gifts for kids will have both strengths and weaknesses."
A child with a smartphone can communicate easily and quickly with friends, but there are a number of drawbacks behind it.
Children lack judgment and abstinence, so they can be costly if used almost daily without interruption.
Kidman pointed out the 'economic risks' and 'online risks'. Online risk means easy access to violent information or pornography online.
But parents have no choice but to buy smartphones for their children. Smartphones are a necessity in school and peer culture. Experts predict that in 2018, high school smartphone users will reach 28,000.
As a result, parents need to see how their kids are using their smartphones.
