why he make this ar...mi phone got explode before? i thought that one is samsung phone?
Yeah one of the Redmi Note 4 got blast over at India. Although, At Xiaomi, customer safety is of utmost importance. Xiaomi India investigated the Redmi Note 4 in the images, and concluded that it was a case of damage due to a faulty third-party charger used by the customer. Nonetheless Xiaomi India worked with the Poorvika store where the unit was bought, and replaced the customer's damaged unit with a brand new Redmi Note 4.
However, after a thorough investigation, the source of this video couldn't be validated, as it has no relation to this case, and was not from the Poorvika store. In fact, it is unclear if this separate and unrelated incident depicted in the video involved a Xiaomi device.
