How many of you are still using an older Samsung cell phone like an S21 Ultra?

Sadly my father pasted away recently, but he left me his Samsung Galaxy S21 Ultra cell phone. It's an older cell phone, but it's far better than a 2023 midlevel Motorola cell phone I bought. It has a great display, sounds good(if you use a USB to headphones adapter) and it seems fast. I think I understand why people recommend Samsung high-end cell phones. Do you have an older Samsung cell phone that is so good that you have no urge to upgrade?

Edit: I've had a lot of people coming to this post say "Your cell isn't old.". Here's my reply to those people so I don't have to repeat myself anymore,

"It's not totally about age, technology is relative because sometimes it can become outdated or some people for example want the newest, latest and greatest thing released. For example I know people that love their Apple products and will upgrade to the newest I-Phone the moment it is released. I never said my Samsung S21 was obsolete, I was just saying as far as technology it's not new. My question is more about if something is still usable are you going to still use it or upgrade to the latest thing like some people do?".

I'm just curious
