Cellphones are student Friendly

Students nowadays are very fond of using their mobile phones for many purposes but how about when it comes to their educational attainment . Does mobile phones do really help them?

There are a lot of mobile applications that can help any student to make them more knowledgeable.
Whatever subject it is , there is a specific application that is made for these subjects.
If a student needs assistance with classwork and does not have access to a computer, a smartphone can be used in a snap.Even games can help the students there a lot of games created to make the students become more interested in learning. Because some students feel bored in listening on their teacher's discussion but because of these games they become alive and they are not just satisfied by playing the game they are also learning in a fun way. There are a lot of schools who banned mobile phones in their schools because of it's negative effect on the students. But instead of looking at the negative side of these mobile phones ,why don't we just look at the positive things brought to us by these phones. Let me give you a concrete example. 
In messenger , anyone can create a group chat . Instead of sending nonsense messages to each other why don't we used our group chat in exchanging ideas on our previous lessons. In that way the lessons that had been thought to us are still there.
Simple as that. For me, the use of mobile phones is not just for entertainment or let's say the use of mobile phones is not just on satisfying the desires of any user/students but also helping them in giving the right educational attainment that they deserve just like what the schools are providing them.
