Simple Gallery Issue：The problem of displaying the number of thumbnails per row

[him7778]

Sometimes when switching apps on the phone (especially when switching from a video app to Simple Gallery), there is a bug where the thumbnails in the gallery change from three per row to seven per row. To fix this, I have to exit the app and re-enter it (when switching back, the smaller thumbnails are displayed first, and I have to scroll back and forth to restore the original size). How can I solve this problem?
