Trap streets are at least traps — that is, difficult to identify as such. What possible reason is there to copy things like "1 1 1 1" or "RO8O7"?

It seeks like Casetify ripped off Dbrand in the laziest way possible.

Casetify almost definitely never looked at actual internals of actual smartphones, so there was no way for them to know the difference between faithfully replicated details and easter eggs.

Maybe same effect but sounds like the purpose here was to include jokes for their customers (otherwise they probably would have included other things than jokes that can be identified by anyone with a brain)
