I am using Shareit application from a year or more. It is really an amazing way to transfer your bulk data without any usb cable in a frequent time. I am using it on my laptop and mobile phone. Its very easy to share things from my laptop to mobile or vice-a-versa.
Now the shareit have updated there software and while sending the data from mobile to computer it just need a QR code. Its really a add on features which Shareit have just added. Its an amazing and attractive features. I like this application and recommend it as a great medium to share your data from one system to other.
