I sew a divider vertically along my pockets to:

a) Create a larger compartment that holds my phone upright
b) Create a smaller compartment for my EDC torch (Usually an Olight i3S with a longish lanyard to grab it out quickly)
c) Prevent these items from scratching each other when in my pocket

Below is a pic with the shorts inside out so you can see the stitching – pretty rough but it does the job perfectly. Was a bit of trial and error getting the placement correct but now I’ve got it, when I get new shorts I just copy one of the others.

Hope this is of use to some of you!
