When I encounter this problem, I will use a software - MobileTrans. This a data processing software, which can transfer the phone data, backup and delete phone data. Its transfer is very powerful. First, it can transfer data between different mobile systems, such as from iOS systems, Android systems, WinPhone and Nokia Symbian. Secondly, it can transfer a variety of data, including Contacts, Messages, Calendar, Photos, Music, Video, Call logs, Apps and App Data. In addition, it is a convenient and fast. You just need three steps to transfer data to another phone.
Step 1. Download, install and run MobileTrans to your computer. Then, the program will have four modules, click "Phone To Phone Transfer".
Step 2. Connect your Note 5 and S8 Edge to your computer with the USB cable. In this process, you should make the Note 5 show on the left. You can use the button "Flip" to adjust the location of the phone.
PS: this software is not only suitable for Note 5, but also for Note 2, Note 3, Note 4 and other models.
Step 3: Now, all contents you can transfer are checked. You can uncheck other content in addition to photos and videos. Then, click "Start Transfer". In the process of transmission, be sure not to disconnect either of the phones.
