This phone case is optimized for 150mm beds. This case prints as two pieces and when put on the phone the F-16 keeps the two parts from sliding away from eachother. Print with the back of the phone case on the bed. Try to reduce warping as much as possible by using a blow dryer to pre-heat your bed or use a heated bed. I printed mine at .2mm with 20%infill and 3 solid layers for the top and bottom. Print without supports. This case fits very snugly together and will not fall apart. There is no hole for the S-Pen on this case. (Who uses it anyway) Sand down the corners of the case with very fine sandpaper. Enjoy. Let me know in the comments if you have any questions.
