Google Tag Manager iframe tag string rendered on the top of the page

At times, the browser on a tablet displays this text on the top of the homepage -

<iframe src="https://www.googletagmanager.com/ns.html?id=GTM-<ID>" height="0" width="0" style="display:none;visibility:hidden"></iframe>

Refreshing the page makes it disappear (but reappears sometime on later page loads).

That is the "noscript" execution provided from Google. At the time, your browser is detecting that you can't run Javascript thus executing that. Are you stating that you see this a text or that you see this in the browser source?

If you're seeing it as text on the page, you will want to ensure that your browser and OS are the latest release. The same code is executed for all device sizes so this would likely be something related to your Tablet than the code here if you're only seeing it on your tablet.

Yes, it is displaying as a text on the rendered page.
