Hey. So if you haven’t unpacked it and you are still eligible for the return policy, leave it like that.
Secondly, have a look here, specs of the s23 compared to the Fe: https://m.gsmarena.com/compare.php3?&idPhone2=12520&idPhone1=12082 Is there something you might need that the base s23 has? What I’ve noticed is that the Fe uses the same chipset / soc as the S22 so that might be a bummer. After using S7 Edge for 3 years and S10 for 4 years, the base S23 for me was extraordinary at least in the battery compartment and overall snappiness.
Thirdly - are you a Samsung fan? If not, please search for alternatives from the competition in the same budget range.
Last but not least - how old are you? If you see yourself working in the next 1 to 3 years then you could start saving some $$$ for a new phone - even flagship level - considering also a trade-in with whatever you get now.
Do a little bit of more research, don’t rush with any decisions and good luck!
Hey OP, why are you asking, some decisions were taken and you feel bad or need to make a decision?
TLDR 7 tears with curved screen - S7 edge and S10. Wanted the S23+ but got the S23 at a good price. 6 months later the little leprechauns on my brain wanted the Ultra. Now I got the Ultra, back to curved screen and a much bigger form factor. Get the S23 you want, all of them are great phones.
