Samsung Electronics Co Ltd (KRX:005935) released a new ad on Saturday for its latest Galaxy Note 4, in which the company took shots at Apple Inc.’s (NASDAQ:AAPL) iPhone 6 Plus, implying the latter had copied the “phablet” form factor three years after it was introduced with the original Galaxy Note.

The new Galaxy Note 4 ad, which was posted on Samsung’s official YouTube channel, begins by recalling the first-generation Galaxy Note with reviews from 2011, when the device made its debut. The video shows Samsung as being ahead of the curve in realizing the importance of bigger screens, although some leading publications had, at the time, criticized the company for making the phone too large and “unwieldy” for everyday use.

“Now it’s not being dismissed by competitors, it’s being imitated,” a narrator says in the ad, which then proceeds to explain the various features of the Galaxy Note, including the S-Pen stylus and multi-window multitasking. The commercial, which ends by announcing that the Galaxy Note 4 will be released in October, also shows tweets to suggest that the new iPhone 6 Plus, which features a 5.5-inch display, is merely an imitation of Samsung's large-screen smartphone lineup.

The new Samsung ad was released a day after Apple CEO Tim Cook told American television talk-show host Charlie Rose, in an interview, that the company could have introduced a big-screen iPhone years ago, but decided to hold off to ensure all the pieces were in place to produce a high-quality device.

“No, we — honestly, Charlie, we could have done a larger iPhone years ago,” Apple Insider quoted Cook as saying during the interview. “It's never been about just making a larger phone. It's been making — it's been about making a better phone in every single way.”

Saturday's ad is Samsung's second attempt to criticize Apple’s new iPhone models -- the 4.7-inch iPhone 6 and 5.5-inch iPhone 6 Plus -- following the phones' launch at a special event in Cupertino last week. After the unveiling of the new iPhone 6 models, the South Korean tech giant came up with six short ads, mocking Apple's new iPhones, the upcoming Apple Watch and the company’s release event.

Apple and its partner carriers began taking preorders for the latest iPhone 6 and iPhone 6 Plus last Friday. Both the devices will be launched in Australia, Canada, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore, U.S. and the UK on Sept. 19.
