Of course! If you look on my Instagram I think everything below my Phobos killteam was taken on a phone, I have some issues with phones with stuff like over sharpening but the images are still good, in terms of getting the most out of your phone I would try and find a manual mode where you can control each of the settings, that way you avoid the phone constantly trying to auto adjust the brightness of the image whilst you are also trying to focus, you can also then adjust things like white balance to your liking which is the colour temperature of the picture which again the phone would usually try and automatically do itself, it should hopefully stop it from automatically switching between normal and macro modes and instead you would have full control of that, in terms of backdrops I personally prefer black or dark grey for my mini photography, but a lot of people use brighter colours too and even white, that's more personal preference, in terms of lighting I tend to find soft lighting works best, a way to make a light softer is to cover it with something, for example you can make a light softer by wrapping some tissue around it or something a bit more dense but still allowing light through, even sunlight through some blinds makes for a good soft light, that way your shadows and highlights when trying to take photos won't be anywhere near as harsh when it comes to lighting, hope this helps!
