OnePlus Switch is a lightweight piece of software which helps you in the process of migrating important data from your old smartphone to a new OnePlus Android device. Keep in mind that this application is alreayd pre-installed on some phones made by this company and you can easily check this aspect by accessing the Settings section of your operating system.
As soon as you launch this app you are prompted to specify if the current phone is the new one or the old one. The rules are very simple, your new device will receive the information, while the older phone is the one sending the data. You'll need to have this app installed on both devices in order to pair them successfully.
After this step is completed, you can proceed by selecting the types of data you want to transfer to your new device. It works with videos, photos, music, contacts, call history, messages, calendar and even apps (without their data). A cool aspect of OnePlus Switch is the ability to know how much data you're about to migrate and you can get an idea about how much time it will take until the entire task is completed.
This tool also can be used for creating backups and restore that data when you need it the most.
