I think there are many good as well as bad influence of using cell phones on kids. Positive is that they get to know about the latest technology attached with the phones like using messenger apps, camera, games, internet, bluetooth etc. I remember when I was kid i didn't know even the meaning of laptops and apps. So its good that kids get nice quality exposure using cell phones nad best part is they remain in touched with their parents through messages or by any means. And negative impact is that sometimes they get addict to these devices!!
