"The directive is a step towards harnessing the full potential of mobile devices which could be a potent tool in ensuring women's safety," Karbonn Mobiles said in a statement.
    
The firm added it has been working on developing a mobile SOS app for women which would be rolled out over the next two months.
    
"This safety app would allow users to send alert messages to emergency contacts with a single tap on home screen; share their location to select contacts at a predefined time or distance automatically enabling their emergency contacts to keep tab on the users location in real time," it said.

The feature will also allow users to raise and send alarms discreetly by simply shaking the device without unlocking the screen as well as send alerts by pressing down the power button for a certain duration.

The government has made installing a panic button on mobile phones mandatory from January 1, 2017. An in-built GPS navigation system would be mandatory for all phones a year later with effect from January 1, 2018. Handset industry body Indian Cellular Association (ICA) also welcomed the notification.
