I have a question wizard (Image thumbnails), I have designed my layout as below for desktop and mobile. I am not sure what should be the best place to include page numbers on mobile screen, as I done it here on the screen. My next and previous buttons are fixed on bottom on both the screens. only on mobile screen the page numbers will scroll(with the images) based on the screen height. Is that poor design? or any suggestions appreciated.
I see your mobile screenshot and as i see you have space before and after next and previous text. You can move Next text to right side and Previous text to left side so you have space between them and you will place number in center. please see below attached image for better understand.
same layout for your desktop layout.
