You guys probably won't believe me but I never adopted the smartphone but since my job requires an app to open the office door now I finally have to throw away my dumbphone and adopt a smartphone.

Can you guys tell me some cool things you can do with smartphones that /g/ anons like me that never had a smartphone doesn't know about?

I will buy the Samsung A16 4GB since it's an entry level phone and I don't want to overspend on a device that I only bought for opening a fucking office door.
