On the Reddit platform, a user named @Maibaum shared their curiosity with the question, ” Why do some (cheap) phone cases have two holes on the bottom right hand side?”
Have you noticed the small hole under your phone’s charging port? I’m sure that many of us don’t know its function and might even overlook it.
Have you wondered why there is a small hole under the phone’s charging port and what its purpose might be?
One person said: It is for phone charms or wrist straps. They used to be popular with flip phones. Never really seen anybody with one on a smartphone, though.
While a third commented: I thought it was cuz the phone also have two small holes there like where ur pin cip or wtev it’s called goes but there’s nothing for those two holes. They’re just. There.
Another added: Wow, I would never have thought if that. Who uses a wrist strap on their phone?
