does page number button in the most bottom left?

if it is, it gives me this (see screen shot) and i did not find any button to search for any specific aayah or surah (i am not talking about part, i mean SURAH).
Thanks!

BTW i what is the criteria to search (a magnifier icon in the app) i mean i tried to search(randomly anything) by putting 1,2,3 and alphabet in the search box but it searches nothing.
