you're using a J3?
try doing this
put your pinky next to the subject you're photographing
and then set the focus thing there
then let's see if it makes the bug look clearer
that's a very interesting bugs you're showing us here
just that all of the pics are pretty blurry but if you try what I told you perhaps it would get you a vivid pic
or buy an external lens for your phone
they're not that expensive
I don't have any but then my phone has a spy cam so it seems
just aim and shoot it's enough
I know someone who has thet J3 and he takes vivid pics with that since I thought him that trick
so try it and best of luck
