Rafayel's phone case should be changed to have his own art on the back of it.

Besides the design on it being awfully bland and the opposite of unique (two things his character dislikes), everytime he pulls out his phone he is shilling a company that that opposes the creative use of their products to the point that they will lie in order to justify attempting to force the owner to give up their legally owned belongings, neglected to prevent forced labor from being used in one of their manufacturing facilities, and generally is known for its greed.

While some level of hypocrisy does make for a more interesting character, this is a brand his character would want nothing to do with. Especially when he can design a unique design that shows off his creativity and skills instead of giving free advertising to a company whose design is just the same symbols copy-pasted a dozen times with zero artistic passion involved.
