But when i try it, the phone covers the whole hand, also the thumb that's covers it

All comes with practice. My usual way is using a layer mask (sometimes several)

see: https://docs.gimp.org/en/gimp-layer-mask-add.html and https://www.gimp.org/tutorials/Layer_Masks/

Using a layer mask to hide the original phone

   

The replacement item might be a single file or more than one in a layer group https://docs.gimp.org/2.10/en/gimp-layer-groups.html Scaled and rotated 

   

Put the two together.
