It's too old depends on how you use it, if you experience slower performance it's time to upgrade.
What do you think about a new phone or a used one? I recommend 256 / 512 GB storage for gaming,
a used S22 or S23 is a solid upgrade. New tablet also an option got a bigger screen if you play a lot at home.
I have an S22 Ultra and S10 Ultra tablet I play sometimes on my tablet.
