Taking decent moon pictures with a smartphone is nearly impossible, you usually end up with a tiny bright blob...If it has manual controls then you can play around with them, reducing exposure, etc for better results, but it will still be disappointing and won't show any detail. I have taken some decent moon shots with a DSLR, and even then it can be quite tricky as the moon is so bright it fools the lightmeter into trying to average out the bright celestial body with the dark sky, so you end up with overexposed shots again. A tripod, a telephoto lens (at least 200-300mm) is a must, and then finding the right exposure is key. Simple exposure compensation of at least two steps back might work, but I always got best results with spot metering and focusing on the brightest spot on the moon so the exposure goes down to around 1/125s minimum.
I know those detaisl probably do not interest you at all, but I love talking about it
