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.
If she keeps her phone for that long get the s23. Mid ranged phones don’t last that long. 3 years max and it’s pushing it. The s23 will get 5 years of support.
