A Mistake Found In 'The Innocent Man,' A Cellphone Held Upside Down?

A mistake was found in the episode of the KBS 2TV's 'The Innocent Man.'

On the recent episode of the drama 'The Innocent Man' that aired on the 4th of October, Kang Ma Ru(Song Joong Ki) was seen looking for a country house in Yangpyeong, after receiving a call for help from Han Jae Hee(Park Si Yeon).

Kang Ma Ru went to look for a first aid kit away from Han Jae Hee. As he went to look for one, he received a phone call from Han Jae Shik (Yang Ik Hoon).

In the scene where Kang Ma Ru was shocked as he found out about Han Jae Hee's schemes, he held his cellphone upside down. He acted the scene, without knowing that. 

Netizens who saw the drama commented, "whoever found that mistake is great," "I didn't even see that when I watched it," "I was too busy looking at Song Joong Ki's face to notice," "he listens with his mouth and talks with his ears," "we should just look passed it."
