No. Any form of addiction does not bring any good to a person. There are a lot of studies that have already pointed out the negative effects of phone addiction such as loneliness, depression, eye strain, neck problems, blurred vision, etc. Moreover, too much use of mobile phones has significantly reduced interaction between two people. Just imagine even two people who are together physically still prefer looking at their mobile phones rather than talking to each other.
Most importantly, children who have been exposed to mobile phones or any other gadgets were found to have delayed cognitive development. Addiction in teenagers, on the other hand, caused them to be distracted in school leading to failure in studies.
