My mom needs a new phone. She is used to Samsung so Samsung it is. A54 is 400€ and S23 is about 800€. Is S23 that much better?
Samsung don’t have screen protectors like in OnePlus from factory. So installing them without dustor air bubbles is gonna be tough.
S20 and S21 are good enough but these S23 and A54 are in local store in good prices. With S23 you can even get a 14" chromebook.
