Problems of mobile phones

natulia [17]

Often people will get adicted to their phones and will be on them in times they arent supposed to.

Such times can be, during meetings for your job which will ultamitly result in you getting fired.

Such times could also be during school which could result in you failing your classes, and having to take them all over again when you could have gotten them done the first time.

You could also be walking around in public being on your phone, and end up running into people, or worse not paying attention and you could end up possibly getting yourself injured, to even fatal accidents.

Even if you are on your phone inside of the car, you could stop paying attention to your car and more to your phone and in the end, end up possibly crashing, which could end up causing you lots of money for repairs, and any other damage that was done, you could also end up hurting other people during the accident, which could possibly turn fatal, not just to people around you, but you yourself.
