^^ I don't see it. Scrolling on the Note 3 screams with no lag. Perhaps your issue is phone based.
I have a Galaxy S3. On more complex web pages, I find there is lag when the page hasn't completely loaded on the GS3. If the page starts loading and there is an image at the top and the text starts at the bottom, I may finish reading the text and want to scroll down to read more text. If the page hasn't finished loading, I find it either lags when I try to scroll or it is initially not responsive. In comparison, on the iPad Mini (this is the only iOS device I have access to that was released around the same time as the GS3) I find I can scroll right away.
If I wait for the page to completely load, then the scrolling is fine on the GS3. Often, I do want to scroll the web page before it completely loads and in this situation with complex web pages, the iPad Mini beats out the GS3.
The situation is different with apps that don't load and render web pages. In this case, I find the scrolling is the same on the iPad Mini compared to the GS3.
