iPhone Camera Hole
No need to worry about the tiny hole next to the iPhone camera lens – it is not a secret camera. In fact, it is a microphone! Apple started adding three mics to their phones since they introduced the iPhone 5. One mic is beside the camera lens, another is found under the speaker grill, and the last one is located on the bottom edge. This makes recording sound easier regardless of the way you hold the phone.

Zigzag Side On Bobby Pins
You should make sure that when you use a bobby pin, the wavy side is facing towards the scalp. Aside from looking cooler that way, the wavy side better secures the pin and ensures it stays in place the entire day. This way makes holding onto hair easier.
