Clothing Mfgrs have been slow to adapt to the cell phone. Cargo shorts and pants were the short term solution by consumers. Carhartt has a “cell phone short” that looks nice enough to pass as a casual short to wear with a Polo, but still sturdy enough material to wear well on a job site. Carhartt also has the iconic carpenter shorts and pants that have a leg pocket that fits most cell phones.
Levi sold their souls to the LGBT***** community which is arguably 5% or so of the population. Not every male consumer in the US has a body like a twink with a eating disorder.
Carhartt also makes durable button-down short-sleeve sports shits which I buy at Academy or the local feed-and-seed store for under $30.
