Note taking - Samsung tablet

Hello

Im starting my maths course in january

I dont plan to take heavy notes during lectures as it is distracting

But i do plan on:

Solving problems step by step in hand during group sessions

Taking notes from the book before lecture/maybe adding extra info after the lecture

Any recommendations
I feel like onenote, evernote, goodnotes all seem badly optimized for android

a handwritten equation converter would be awesome too

Any help is appreciated

merry christmas
