Stylus hipen h2 unstable

Hello is there a solution to make the stylus hipen h2 stable? have updated the pen. But found that writing is still missing or is there a stylus pen, any model, any brand that supports it and writes smoothly? Purchased for children to study online. But I found that there is a problem with using a pen to write in Onenote. Please answer and help fix the problem. because there is no money to buy a new device But if you have to buy a new pen, you can buy it, but ask for a model that really works. It’s terrible if there’s no solution.
