Delete Browsing Data in Samsung Internet auf Samsung
Samsung Internet keeps a running record of almost everything you browse: history entries, cached page data, cookies, saved passwords, autofill entries, and location permissions granted to individual sites. This data speeds up return visits, but it also builds up over time and can cause outdated pages to load from cache, autofill to suggest old addresses, or location access to stay active for sites you no longer use.
You manage this inside the browser itself, not in the general device settings. Open Internet, tap on Menu, then go to Settings ➔ Personal data ➔ Delete browsing data. There you get separate options for browsing history, cache, cookies and site data, passwords, autofill data, and location access data, so you only remove what is actually causing the problem.
Selecting everything logs you out of most websites and clears autofill, so that option makes sense mainly before handing over or reselling a device. If you only need to fix a loading glitch on one site, clearing cache and cookies is usually enough and leaves saved passwords untouched.
