I tested it now also on these devices:
- Galaxy Note 8 (Android 9) and there is no OK button after taking a picture
- Xiaomi Redmi Note 5 (Android 9) there is an OK button, but after pressing it I get no image
- Galaxy Note 3 (Android 5) I get the same error as on the Galaxy A3 (like Taifun)
- Motorola Moto G (Android 5.1) same error as before
- Galaxy S6 (Android 7) as before
- OnePlus 6 (Android 10) I get an hook (instead of OK) which is not clickable.
On all devices the Pictures folder is not created.
