I just wanna say you’re mom is very tech savvy for an old person. My mom wouldn’t know what a call recorder is. She just got the s23 ultra because it has the biggest screen. That’s all she cares about. Old, wants huge font, huge screen. Money doesn’t matter since old people benefitted from some amazing economics.
Now there’s a chance your mom is not really old and you’re just very young, in which case, congrats and i hate you 😀
compare the price of fixing this old ass phone vs getting a used less old phone.
seroiusly.
your choice of s8+ plus the cost of battery replacement vs s23 ultra (one of the most expensive new phones) is specious.
get some less old ass phone for less money. like a used s20 note or something. depends on your region and prices available on less old ass phones.
