Mobile site developers can enable vibration on your smartphone using the Vibration API. They don't need to request your permission for that. This interface was developed for cases where tactile feedback is required. It can be used in web games (for shooting or in races) or for duplicating audio signals for users with hearing problems.
Phishing sites have learned to use vibration to capture the user's attention and intimidate them. For this reason, the Vibration API is disabled in Yandex Browser for Mobile by default.
- Allow sites to use vibration
- Tap in the browser (if you don't see the icon, press the menu button on your smartphone).
- Tap Settings.
- Scroll down to More settings. Tap Site capabilities.
- Turn on Allow sites to use vibration.
