Taking pictures in the dark is in fact a very difficult task. You worry about not being able to see the picture in the darkness. You also have to worry about possible over exposure when using flash. A good way to reduce these challenges, I would say, is try to turn on night mode (if possible) and lower your flash. You can also move farther back so the flash does not make the image to bright.
some of the difficulties is were its too dark too see what your trying to get. and a way to fix that is mayby turn on flash on your phone of get a phone that is good at taking night pictures
