I'm not saying this is what's happening to you, but in my case this is exactly what I believed for many years.

And then it turned out that typing-vs-hand-writing benefits being equal was in fact due to how atrophied my hand-writing skills were.

I've learned that once I got back into fluent hand-writing in a flow-state, the benefits for learning, memorizing, and understanding, were so overwhelmingly superior to keyboard-typing, that I resented the cognitive handicap I had placed upon myself for literal decades.

Now I always carry a tiny spiraled notebook and a Rotring pen. They're as indispensable and practically useful to me as my smartphone.

Writing by hand is harder and slower. This gives you time to ponder, understand the important point better, try to formulate it shorter and thus search for and extract the key points. IOW, it forces you to study what you write, not just register.
