Some Android phones dont get on with fast cards. I had a class 4 16Gb card which was fine, tried a class 10 32Gb and the phone would see it and then not recognise it. Got a newer phone and its fine with the new card. If you want to copy apps and data across and have got root, TiBackup is good. If you don’t have root, try using Helium. It allows you to backup to a cloud drive (google drive) and then restore from there. I think I got the paid version, but it was only about £4, but it worked well.
