The new version of the Opera browser for Android also has a new media player, thanks to which users can play any video or audio file directly in the browser without downloading third-party applications on their Android devices.

The WebSnap feature was first introduced in the Opera desktop browser. With it, users can take pictures online and creatively personalize them with a range of editing tools, as well as a unique collection of emojis.



With WebSnap, users can blur images, add text and colors, or simply share a snapshot with others right from the browser using standard functionality.

The new media player in the Opera browser for Android allows users to play all kinds of audio and video files in the browser, eliminating the need to use third-party players.

The new media player also has Play Queue support, allowing users to watch or listen to media files in any order. At the same time, you can continue to surf the web while watching videos or listening to audio files, since the media player supports picture-in-picture mode.

The player menu has an option to adjust the playback speed and video quality, if supported by the file. Users can also activate closed captioning and choose from seven different languages ​​- English, French, German, Italian, Russian, Swedish or Turkish.
