OneNote Android no longer working with my stylus?

Question

OneNote Android no longer working with my stylus?

Matthew Zhang 15

Recently (and seemingly out of nowhere) the OneNote application on my phone stopped working with my stylus. I have a Samsung Galaxy S25 Ultra so there is a built in stylus.

For some reason now, there is a major delay when writing (where writing only shows up after I lift the stylus), and the side key on the stylus (which previously activated the eraser feature while writing) no longer works. A few days ago, OneNote would also register both my finger and the stylus tip as a writing tool, so I was unable to pan around. This issue seems to have disappeared today, but I am still unable to write normally.

I can only replicate this issue in OneNote, and the stylus works (along with the side key) in any other writing application (Samsung Notes mainly). What is the issue here? Genuinely just appeared out of nowhere.

I have tried clearing the cache, uninstalling and reinstalling, and checking for updates. Since this issue seems to be isolated to OneNote specifically, I have not tried anything else.

I have exactly the same. The side key on the stylus on a Samsung Galaxy S25 Ultra no longer has any effect in OneNote though is fine in other apps, it stopped working at the end of January, and reinstalling OneNote has no effect.

I have the same issue, recently the erase on my onenote on Samsung Galaxy S25 does not work anymore. I have already deleted the app, restarted, reinstalled, but does not fix the issue. Does anyone have a fix for this? Or is it a bug?

Same issue on Samsung S25 ultra. Pen still functions normally in all other apps (side button erase and palm/finger rejection). In one note erase does not work, and finger acts as stylus and therefor cannot pan and zoom with fingers. Onedrive cloud does not recognize stylus function.

Tried uninstall reboot reinstall, same result.

Hello, dear users and team.

Hope you're fine.

I'm facing a similar problem. Here, the situation starts when I turn to landscape mode.

Thanks.

Hi,

Try uninstalling the OneNote app again and then restart your device. This will delete the remaining cache on the app. Install the app again.

If the issue persists, can you open and sign in to the OneNote cloud? See if you have no issue with the stylus,

If there is no issue, please try contacting MS support for feedback on the OneNote app, or you can send direct feedback from the Microsoft 365 apps. This will more directly submit your concerns to the applicable team
To contact MS support, please follow the steps below.

Open this link: Contact - Microsoft Support
In the box, "We're here to help", type Microsoft 365, click the Get Help, and then scroll down. Click "Contact Support" below.
In this section, you will need to sign in to your Microsoft account.
Select "Microsoft 365 and Office" under Products & Services. As for the category selection, choose "Technical Support", and click to confirm
You can select " Chat with a support agent in your web browser " to access the chat window.

In the meantime, please use OneNote cloud for a while until you receive a response or update.

If you require additional assistance, please let me know.

Stay Safe!

Does the cloud work with a stylus? I assume the cloud one you are referring to is the website version. From what I know the stylus acts as a cursor/touch input when used in a browser but I could be wrong.

I will be sure to give this a try but is that the only solution?

This is not a valid solution. It a hack. I just bought S26u and am also facing these identical issues. This issue is nearly 10 months old and still occuring. Claude could give a more helpful response. How would you feel if your answer is worse than what some might call AI slop?
