Despite Chrome's wide availability these days, most OEMs still make a customized version of the AOSP browser for use on their devices. HTC is no different, but it has taken the additional step of adding the Sense browser to the Play Store so it can be updated independently of the system. It even comes with some new features in this first Play Store build.
Here's the changelog listed by HTC for the new browser version.
- Text reflow: Depending on zoom levels, text will be wrapped to fit the width of the screen for easy browsing.
- Read later: Save an article to read later, even when connection is off.
- Redesigned interface that’s clean and easy to read.
The Sense browser (or "HTC Internet," if you must) works on HTC devices running Sense ROMs based on KitKat or higher. That means no Google Play Edition devices. Some of the early reviews point to the removal of the labs feature in this build as an annoyance, so you might want to archive the version that came with your device just in case.
