After the last ayah of a page, it automatically changes to next page before the next ayah has been started. This is incorrect for two reasons. One, you are not able to see what you recited last, especially if there’s a small mistake the system allows you to progress (if the settings is like that). Two, in hidden mode you’re able to understand which Surah is next (especially if there’s next suraj starts on beginning of the page; ideally in this mode the reciter should guess what is next).
Solution: After every ayah, including on the last of a page, it shouldn’t move to next ayah (page) until have started reciting. (In fact, this is how it is followed throughout when it is regular ayah; i.e. you cannot even see ayah number if it is in hidden mode).
Hope this small correction is incorporated in the next revision. جزاك الله خيرا
