A new report is showing off the LG Flex – or G Flex - in three press renders, boasting a more detailed view of the curved smartphone.

Engadget purportedly obtained the press renders of the 6-inch smartphone, which is set to go head to head with the Samsung Galaxy Round.

LG previously confirmed that the new OLED panel will be 0.44mm thin and weigh just 7.2g, "even with a 6-inch screen", lending further proof to the Flex's rumored size.

The flexible panel will use plastic substrates instead of glass, allowing it to be bendable and "unbreakable".

Engadget's sources are also saying that the new smartphone will be ready for launch next month, which isn't the first time November has been named for the LG Flex's launch.

Though nothing blatantly official has come from LG in terms of pricing and availability for the Flex, LG has already confirmed that a 6-inch curved OLED display and curved batteries are already in production, so a November launch may not be too far off the mark.

The right kind of curve

While both Samsung and LG have competing curved smartphones readying to be launched, the above renders show again that LG may be curving differently to Samsung.

Earlier rumors for the LG showed a similar designed, where the Flex is curved from the top to bottom, essentially curving from the ear to jaw if you were to hold it to your ear.

Samsung's competing curved smartphone, the recently announced Galaxy Round, curves from the left to right, hugging around your cheek if held up to your face to take a call.

The question then becomes: which will be more comfortable and organic to hold? Until LG releases official photos and, more importantly, we get hands-on time with both curvy phones, we won't truly know.

• While Samsung and LG battle it out in the "flexible" display sphere, the internet doesn't care much for curved smartphones.

The accelerometer motion sensors within most smartphones could potentially be used to track the web activity of individual device owners, it has been claimed.

Stanford University phD student Hristo Bojinov says that because the accelerometers work 'imperfectly' they provide a unique ID when idle. That's potentially enough for advertisers to follow users around the web.

According to Bojinov, the method is similar to the 'cookie' files that are used to track web activity, except, unlike cookies, the accelerometer data cannot to switched off or disabled by the user.

The researcher said he was unaware of whether marketeers or advertisers had already exploited the loophole, but would be surprised if the possibility wasn't already being investigated.

See for yourself...

The 'alarming' discovery is part of research investigated whether the various sensors sitting within smartphones can be used for tracking purposes and will be published in the coming months.

To illustrate its findings, the team of researchers has set up a website, showing users how they can generate their unique sensor ID data.

The method involves navigating to the Sensor-ID.com site, touching the screen, flipping it face down and flipping it back to reveal the identifying numbers. Repeating the experiment generates identical (or very similar numbers).

"People need to consider the whole system when they think about privacy," Bjinov told the SFGate site.
