I previously thought it would be a way to upgrade phones faster without losing (much) money.
Say, you have a 800$ phone and you want a new 800$ phone. Most people would just buy a new one for 800$ (outright or installment, doesn’t matter) after 2-3 years. My idea was to buy a new phone every year, sell the older one for half the price and voila - you paid the same amount but got two phone upgrades.
The problem with that logic is that reselling takes time, energy and luck to get the price you want, plus it is possible to buy new phones for cheaper by just waiting anyway.
In my experience, several devices don’t display the emoji as a correct icon (instead show the rectangle “tofu”), but they still work with it.
