Everything about the Zfold is cool except the security level that has to do with fingerprint. It's difficult for the phone to recognize fingerprint because the sensor is at the edge of the phone instead of being at the center. I eventually ended up with face recognition.
In the beginning, I had my doubts. However, having used my ZF6 for 6 months, I would never return to a non-fold phone. I have always been a tech-no-geek, but the larger phone is excellent as I age, now at 76. I love my ZFold 6. The only improvement is to put the best camera in the next generation.
So far it's pretty good. No noticeable changes from the fold 5 except smaller gap and sharper edges. I hope the screen protector doesn't start to lift in the middle like the 4 and 5.
