Samsung Internet Browser (or simply Samsung Internet) is a mobile web browser for smartphones and tablets developed by Samsung Electronics. It is based on the open-source Chromium project. It is pre-installed on Samsung Galaxy devices. Since 2015, it has been available for download from Google Play, and recently it is also available for their Tizen-based smartwatch via the Samsung Galaxy Store. Samsung estimated that it had around 400 million monthly active users in 2016. According to StatCounter, it had a market share of around 4.98% (among 53.26% for all Chrome variants) around May 2018. Most of the code differences to the standard Chromium code base were introduced in order to support Samsung-specific hardware, such as Gear VR and biometric sensors.
