Trylobit

Hi! I'm a new owner of X-T20 and I love it. I'm using it mostly for photography, but from time to time I'm using it as a C camera. I wanted to take advantage of the wireless remote control, but I was shocked that when I try to record video using android app video settings change from 4K 25fps to HD 29.97fps. I can't find where to change it. Can anyone help me? Thank you in advance!
