Chinese smartphone maker Xiaomi's Global Spokesperson Donovan Sung was left embarrassed for reportedly posting a fake camera sample image on his Instagram account to promote the newly-launched POCO F1. Users on social news aggregation and discussion platform Reddit shared the image which Sung shared on his Instagram account, claiming it was captured by POCO F1. However, the image was apparently shot by Xiaomi Mi Mix 2S smartphone as it had the "Mi 2S" watermark at the bottom left corner of the snap, found the Reddit users. After facing criticism, Sung removed the photo. Xiaomi was yet to respond to this controversy. In a similar instance, Huawei was recently caught when an actress from one of its commercials showcasing its new Nova 3 smartphone posted behind-the-scene photos on Instagram, revealing a DSLR camera being used to take selfies and not the smartphone. A Reddit user that goes by the name of AbdullahSab3 discovered that Sarah Elshamy, one of the actors in the ad, posted photos on her Instagram page, and one image revealed a photographer shooting the "at-home selfie with a DSLR".
