City transit officials are telling riders not to charge — or even use — their Samsung Galaxy Note 7 on subways and buses because of a safety hazard. NY1's Lori Chung has the details.

"I've heard that it's been exploding, fires."

Reports that the battery on the Samsung galaxy note 7 can ignite and burn leading to a bad reputation and now a warning from transit officials — tweeting Monday:

"I can sort of understand why they wouldn't want it on the train," said one straphanger. "I don't think I'd be comfortable on the train with that to be honest."

"If it's going to keep us safe why not," another rider asked.

Some commuters glad to hear that straphangers are being advised to turn the smartphone off even before entering the station. The problem? The note 7's lithium ion battery which can catch fire when overheated.  

Samsung has issued a global recall on the device saying in a statement "customer safety is our highest priority. We are asking owners to power down their Note7 devices and exchange them today."  While none have ignited on MTA property some aren't surprised the agency is playing it safe with a potentially dangerous device.

"When the hoverboards came out they also caught on fire too and inside the train stations they put up signs 'don't ride with them, if you're traveling be safe or don't travel with them at all,'" said another subway rider.

Some now hope officials take enough action to get the word out so that everyone with the Note 7 gets the message.

"I guess it should be a better effort to let the public know what's wrong with the phone that way it can prevent any injuries or anything like that," said one.

This comes after the federal aviation administration issued a similar warning urging travelers not to use the Note 7 on planes.
