Looks like Samsung is looking towards pushing out some aroma mobile handsets in the future, as according to cellpassion, Samsung’s latest patent application is for a fragrance strip embedded into the mobile handset.
Basically Samsung wants to embed a smelly strip into the slider mechanism of a slide handset and/or the hinge of their clamshell form factor handsets and thus every time a user opens their handset friction put against the fragrance strip will release the smell.
There’s nothing about whether the user will be able to replace the strip once it runs out of smelliness though.
