The Files and Preview app conundrum in iOS 26.
Every time I open a file or a photo in my Files app, it automatically takes me to the new Preview app. The problem with that is you can no longer swipe between files or photos in the Files app. I keep certain photos off my camera roll (no not those kind), such as really old kids’ photos from my wife’s old phone, but I can’t even scroll through them like I used to. Quite literally every time I click on a file, it goes to the Preview app.
Same thing goes for the Preview app. If I try to open the same folder of photos in the Preview app, you can’t scroll between photos in any folder. You’re stuck looking at photos one at a time. Tap a file, look at it, tap back, and tap the next file.
The only way to solve this problem right now? Delete the Preview app.
I think Apple needs to let you view your files in the Files app like it used to, and if you want to open it in the Preview app, add that option to the share sheet.
