Having its "Once Upon A" prefix named after "Once Upon A Deadpool" (2018), Once Upon A Smartphone is a version of smartphone watered down for kids. This is intended to be a Christmas gift rather than akcually being used as a functional tool, as kids are prone to asking for smartphone to Santa during Christmas even though they're still too young for smartphone.
Instead of a real phone, I got my little brother a Once Upon A Smartphone for Christmas—now he can pretend to text and play games without the screen time worries!

The most sweetest fandom. ONCE is the official fandom name for the South Korean best girl group Twice. Once is a lovely, harmony and crEAtIVe fandom. The reasoning behind naming TWICE's fandom "Once" is simple and adorable: if fans love the group even once, the girls will repay them with "twice" their love!
Once doesn't oftenly argue with other fandoms. But if you try to mess up with them, you'll better PRAY THAT YOU WILL STAY ALIVE TOMORROW. They really love their girls. In return, Twice gives them love, hard work and amazing contents for them. Twice is the reason for Once to smile everyday.

A prefix representing a kid-friendly version of a pre-existing product or concept, named after "Once Upon A Deadpool" (2018). It signifies an attempt to create a more suitable and sanitized version for children.
As YouTube Kids had been corrupted by the emerging phenomenon called Elsagate, YouTube should try another attempt to make a kid-friendly version called Once Upon A YouTube, featuring daytime TV-like censorship modeled after Disney Junior and Disney Channel.
