Should I sell my Lenovo Legion Duel 1? (PHP)

My uncle is giving me his Lenovo Legion Duel 1, and I was planning to sell it so I could get a newer phone instead.

I’m kinda conflicted though because the Legion Duel 1 is still a pretty good phone, and I feel like it would be a waste to sell it. At the same time, I’ve been wanting to get a newer phone for a while now, mainly because I want something that’ll last me longer and be more practical for everyday use.

So yeahh, would it be better to just keep the Legion Duel 1 or sell it and use the money to get a newer phone?

I’m not really sure what to do
