For those who don't know about project aura or modular phones, smartphone is made of modules which we can think of parts like camera,display,processor,speaker etc. All these modules will be connected to each other with the help of attachments or magnets. its just like a puzzle in 3D. When the puzzle gets completed it takes the shape of the phone.
 So what's the advantage of using this phone?
Whenever u feel that your smartphone is outdated,just change the module like as for example i have an camera in my smartphone with resolution of 8 Mp and i want a better camera, what i will do is just get a new camera module from the market and replace the camera. No need to buy a new smartphone. All the above modules like camera,display,processor,speaker can be changed.
