I think I am going to bring back iphone x to the store because it is not the only one problem.. I realy like portrait mode, I am taking pictures every day, and I noticed that one day something wrong happened, it was impossible triger any of photos in portrai mode, it is impossible to triger the depth effect in same conditions as I do it before. And after I try reset all settings, It helped me for a short time, this problem apearing every 1-3 days, and I don't have any ideas how to solved it without reset all setings every 3 days, it is realy annoying.
