Samsung Internet Not Secure Warning — HTTPS Certificate Errors on Samsung Browser

Fix Samsung Internet browser showing 'Not Secure' or certificate warnings when visiting websites that appear secure in other browsers. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Samsung Internet is the default browser on Samsung Galaxy devices with its own certificate store. It may show security warnings that Chrome does not due to different certificate validation behavior. Samsung Internet supports its own certificate authorities that may differ from Chrome's. The browser has a secret mode (like incognito) with stricter security settings. Samsung Internet Ad Blocker and tracking protection can interfere with some secure connections. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Website SSL certificate not trusted by Samsung Internet's certificate store. System date and time incorrect on the Samsung device causing certificate validation failure. Samsung Internet is outdated and does not support modern TLS features. Ad blocker or privacy extensions interfering with HTTPS connections. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Update Samsung Internet from Galaxy Store or Google Play Store to the latest version. Check device date and time: Settings > General Management > Date and Time > set Automatic. Clear Samsung Internet data: Settings > Apps > Samsung Internet > Storage > Clear data. Disable ad blocker temporarily: Samsung Internet > Settings > Extensions > disable ad blockers. If site specific: the website may have an SSL configuration issue — test with Chrome to compare. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
