New Delhi, India: A smoking Samsung phone sparked alarm on an Indian flight on Friday, the airline said, weeks after the manufacturer recalled 2.5-million units of its latest model when batteries began catching fire while charging.

Airline IndiGo said it had dealt with an incident involving "minor smoke" coming from a Samsung Note 2 device in a passenger's hand luggage on a flight from Singapore to the southern Indian city of Chennai.

The phone was not the same model as that involved in the recall.

"IndiGo confirms that a few passengers travelling on 6E-054 from Singapore to Chennai noticed the smoke smell in the cabin this morning and immediately alerted the cabin crew on board," the airline said in a statement.

"(The crew) observed smoke being emitted from Samsung Note 2 which was placed in the baggage (of a passenger) in overhead bin."

Crew used a fire extinguisher before submerging the phone in water and the plane made a normal landing.

The world's largest maker of mobile phones recalled 2.5-million units of its top-of-the-range model, Note 7 after its batteries began catching fire while charging.

The recall has put fresh pressure on Samsung, which is already squeezed by competition from Apple in the high-end market and Chinese rivals in the low-and mid-end segment.
