Data Transfer Tool is an Android system app that makes switching from an iPhone or older Android device to a newer Android smartphone such as a Pixel easy and seamless. In other words, the app makes transferring data from an older phone to a newer Android easy. The app helps transfer apps and app information, music, videos, photos, contacts stored on a SIM card or device, text messages without media, and most of the older device’s settings. The calendars and contacts that copy to the new Android phone would sync and upload to a user’s Google account. This information syncs in when signing in on the new device.
