Smart switch: Transfer my data is a great app to switch between smartphones easily without worrying about the data that will be transferred. This application is designed with the user in mind, so it is easy to use and the interface is very intuitive.  

Use this up by opening a hotspot on your smartphone so that other devices can connect to it. Once you have selected the device you want to switch to, you will be able to choose the files that you want to transfer. You will be able to select either photo, videos, audio, or contacts.
