I just had to make my font size smaller. Now it works great. Wish there was more English in the app. I can't look past Terms of ServiceandTerms of ServicePrivacy Policy. I'm stuck on that screen. With no way to scroll down or back out of it. I have an S23 Ultra.

This app is good and allows you to choose your e-ink photo on the phone case you have. It works well and initially I had an issue signing up for an account but once you get past that the rest was easy. You can create AI photos, or use your own or choose from their selection.

It worked perfectly fine until recently, the button to select a image after you picked the one you want to use has moved to the very bottom of the screen and made it impossible to click on it because of the Phones Main buttons at the bottom
