What do we do with our old phones

HI there,

I am back with another information about useful technology. So quickly we come to the topic. What makes you happy when your phone's application get out dated? What do you do with it? The answer is very easy. But did you realise  what can you do with an old phone while it's no more updated for using it. Now   here is another answer with a solution. We can use the old phone by using it as a walkman, well we can talk about simple walkman later some day, but when you need this phone in listening a song or if you want to watch the movies you can easily make it an mp4 player and an mp3 player either. This technology will give you an entertainment. At first we use this mobile by sharing our files through whatsapp or social media, now a days we can share our photos and other things by a bluetooth device which is still  active in it. So we can say this old technology is still a gold. Thank you
