@myi you might be disappointed with the battery life of an s10, and especially the s10e, and it's worse if you get a used one.
Lol, first thing I would do is send it to samsung for a battery replacement!
Yes that's one thing all my time using samsung Products, I will say turned me off.
The battery on all my devices I've ever owned were a real disaster.
From the S4,S5,S7,S9.
I'm leaning towards getting another Samsung only because I've been with them for quite a bit.
Though I was using a Motorola X4 for a while which was great, speed was pretty good, though there's always room for improvement. And memory was capped at 64gb plus expandable with an sd card.
So then again doesn't have to be samsung, I would settle with a One plus, pixel, LG, Motorola. Or another solid phone.
Either I would find someone here on the forum selling the phone or buy from swappa.or directly from the company if they're offering trade in offers and ...
Yes a new phone is not a used phone.
But with a headphone jack and an sd card that would mean I would need to get an earlier model device.
