Ridges In Audio Jack
It turns out that the ridges on audio jacks help keep the wires in place and protect them. They are also very useful since they dictate where the sound is channeled to. One band is meant for the right headphone, while the other one is meant for the left headphone.

Silica Gel Packets
Your new purses or shoes often come with silica gel packets. What are they used for? They keep your item fresh and clean before you start using them. They contain a “desiccant” that wards off moisture and absorbs humidity from the air. You should use this instead of rice when you wet your phone.
