I had my old Z Fold 3 which was 3 years old when my new Z Fold 6 came in. Everything was easy to set up right out of the box. I did have an issue with my E SIm getting it downloaded from AT&T. Once it was download, service was a breeze from that point. My 256 GB old phone, which was half full, took about 2 hours to transfer. Very happy with my new phone. Battery is awesome and screen is beautiful compared to my old phone. It is a winner in my book.
I had the fold 5 which I loved. The fold 6 gives you better battery life and better performance. The screen is easier to see in bright sun light. The seam in the middle is not as noticeable as the fold 5 but is still there.
