My mom's searching for a new phone for around 300€ in Germany. She's been using a a22 for 5 years and now she wants a new phone. I've been thinking about the a56 so she can stay in the Samsung Ecosystem but I'm not sure what she should get. I can also get refurbished. I've seen a pixel 8 pro on back market for around 300€. Please help me find something.
