I have no issues with my fold 2. I'll go back to my note 20U and it lasts a day at most and I'm back to the fold. There's issues with the fold 2, if you use the edge panels, you're limited to what they put on there, there is no store to buy or add extra panels. Good lock has pretty much zero support for the fold 2, I can't move clock back to the right, change the task bar settings. I used to, till Samsung released a update. If you like to do themes, they are limited, a lot of theme developers don't want to bother with the different format. Those are some of the things I don't like about the fold 2. It's software related, and more annoyance then anything. The phone itself works great, love the skinny aspect of the front screen using one handed and being able to open it for big screen. I use both screens equally IMO. The build quality is surprisingly good.
I'll be looking at the fold 3, but I don't know if I'll get one, will have to see how the rumors play out. Under screen front camera will call to me big time, I don't use the camera on the inside screen anyway, so no hole for the camera is a bonus for me. Spen support is good, but if it doesn't have a silo to store the spen inside the phone then that to me is the fold 3 doesn't have a Spen.
Let us know how you like the fold 2. Are you going to keep it, return it and go back to your old phone, or return it and wait for the fold 3.
