Disclaimer: if you are not someone who uses a mini tablet/tablet along with a cell phone often and would appreciate having both devices in one, this post is not for you.
I was skeptical at first regarding foldables as well, until I traded in my iPhone 12 Pro Max for the Z Fold 3. I couldn't wait any longer for Apple to release a foldable phone and I was using my iPhone and iPad Mini all the time so I figured it would be great to have a 2 in 1. I have the Z Fold 4 now and I will never go back to a traditional slab phone. I love having a cell phone and mini tablet in one pocketable device. I prefer having the Z Fold 4 in my pocket over the iPhone Pro Max, as the iPhone Pro Max is too wide to be comfortable. The Z Fold 4 is a multi-tasking beast as well. I believe Apple will make a great foldable phone, and if/when they do I will consider coming back to iOS. If you are on the fence at all, give a foldable a try. It is impossible to understand how great they are unless you've owned one. You can always return it, if you don't like it. Android has come a long way over the past 4-5 years, and this is coming from someone who used to absolutely despise it. I found that Android 12 and 13 to be just as stable as iOS, which has gone downhill drastically over the past 3-4 years. For reference, I had owned every iPhone from the 4 to the 12. Food for thought anyway 😁
Side note: I had a Z Flip 4 as a backup phone and it was not good. I just don't understand the appeal of this type of foldable. Having to unfold it all the time for pretty much anything you want to do. It was a huge no-go for me anyway. To each their own though of course.
