Is there any way around this?

I have an older phone (Samsung galaxy note 5) and about a month ago, there was an update for Pokemon go and after I updated it, it wouldn't let me sign in because my phone is no longer compatible. I have already tried seeing if there were any updates for my phone, but there isn't.

I don't play a ton anyways, but I still want to play. I do need a new phone, but I won't be able to afford it for a while.

Is there any way for me to still play on my current phone?
