Sony's latest top-end smartphone vibrates in time with movie and TV action scenes and video games.
The Xperia XZ2's rumble tech adapts a feature originally developed for the firm's PlayStation controllers.
It also records "super-slow-mo" videos at a higher resolution than Samsung's Galaxy S9, according to a BBC report.
Sony has, however, pioneered other phone innovations in the past - including a 4K screen and waterproofing - only to see its sales still struggle.
In 2017, it was only ranked the 15th best-selling smartphone manufacturer, according to research firm IDC, with a 0.94% share of the market.
"It is very frustrating when we bring something out to the market first, and maybe the competition comes a year later and does kind of the same thing and gets more buzz around it," acknowledged Sony's senior manager Adam Marsh.
"We will definitely be improving how we go to market with the product this time to really ensure the consumers understand the experiences that we can offer."
But analysts question both the appeal of the new features and also whether the firm is willing to spend enough to market them.
"The rumble tech is a bit of a gimmick," commented Ben Stanton from the consultancy Canalys.
"I've tried it. It does make gaming more immersive, but I don't think it works very well in a video context.
CCS Insight's Ben Wood added that he thought the phone's new industrial design was a major improvement on the past, but that he also had doubts about the new flagship's prospects.
"Taking on Apple and Samsung requires eye-watering investment that Sony is always going to struggle with."
Higher-def slow-mo
The XZ2's other new features centre on its camera.
Last year's model was the first phone to be able to stretch out 0.2 seconds' worth of action to create six seconds of footage, in 720p resolution.
Samsung made much fanfare of adding a similar feature to its new phones on Sunday.
But Sony has now trumped that by delivering its 960 frames-per-second footage in 1080p - twice the resolution that its South Korean competitor offers.
It said it had achieved this by using a customised version of Qualcomm's Snapdragon 845 chip that features its own image signal processor technology.
The potential problem for the firm, however, is that early reports indicate Samsung's version is much easier to use.
"And Samsung has done some brilliant work with AI and image recognition to capture the fast moments as they happen - it's actually learned from Sony's mistakes to launch something better, even though technically it's not to as high a standard." said Mr Stanton.
Another new camera technology in the XZ2 is the ability to record 4K videos in both a high dynamic range format - meaning images should appear more vibrant and realistic when played back on a compatible screen - as well as in 10-bit colour.
