Best Camera and Gallery app - eviltoast

Hey guys, Im trying to get rid of google apps so I have installed GCAM port MGC_8.9.097_A11_V4_ENG and simple gallery pro from fdroid. They are both amazing, but when Im in camera app and I want to use thumbnail to open last picture in gallery, it does open but then after 2 sec screen refreshes like I reopened the app. And even worse, if I try to open gallery right after taking picture it will open new picture for 2 sec and then screen refresh and switch to 2nd last picture. Anyone had simmilar experience? Different versions of apps didnt help and cant find any replacement that works. I also cleared catch and data for both.

Im using non rooted Motorola G42
