Hello, I noticed that in Android version v0.41.100 the karaoke story doesn't go any further, even though you knocked back on the wall and confronted Jun and his men. This means Jun doesn't kidnapp and beat up Matt. So you don't get the pictures for the gallery.
I also noticed (already in previous versions) that some images do not appear while playing, but only become visible through the cheat. For example, when you sit with Damian in the café for the first time and ask if he is always there alone or if he likes the waitress, the pictures do not appear. Another example, when Matt is playing on her boobs in the classroom, the image of her turning her head to the side does not appear. Also, the cell phone photo from the locker room that Matt took after he forced her to touch herself doesn't appear.
Also, there is no way to send the selfi in the blue maid dress, that Violett is supposed to give you, to Damian and Matt. The maid's dress never appears.
I hope it was helpful that I wrote this down for you.
I love this game and enjoy playing it a lot. :)
