A replacement model of the fire-prone Samsung Note 7 smartphone began smoking inside a US plane on Wednesday.
The incident has prompted fresh investigations by the Consumer Product Safety Commission.
It’s a major and possibly costly embarrassment for the tech giant which has been trying to salvage its reputation following a mass recall of the original Note 7 model.
Samsung Electronics said in a statement it was working to recover the device and to understand the cause.
The public have been warned that Note 7 devices should be powered down and not charged while on planes.
