I had android 13 on S5, I wont say it was smooth, but it was more than usable. I replaced it mostly because 2GB off RAM was starting to get on my nerves. I couldn’t have more than 2 apps open without it putting to sleep the previous one. Multitasking was not very good on such a old phone.
I cant imagine what could be wrong on 3 year old phone. If it is not broken just install LineageOS on it and you should be good to go.
It won’t get the latest Android OS update and it’s also starting to lag a bit
