Good or Bad

I read 5  Side Effects of Your Smart phone Addiction by Amanda Hawkins.The author said that using your phone  constantly are given the next side effects,Text claw and cellphone elbow which equals sore muscle and finger cramping next is,posture and text neck next,is computer vision syndrome eyestrain, blurred vision, dizziness, and dry eyes,Nomophobia which means scared to not have your phone with you Phantom Pocket Vibration Syndrome which explain its self well.I think that most of these accusations towards the cell phones mostly are true because i experienced mostly all of the and i now many of my classmates have too.
