Camera lenses set for the iPhone 12 have encountered problems, according to a note from analyst Ming Chi Kuo, seen by 9to5 Mac. However, it could save Apple some money.

The problem was spotted during a high-temperature, high-humidity test designed to ensure that the cameras can cope with use in tropical climates… The issues occurred with the camera modules destined for the non-Pro 5.4-inch and 6.1-inch models, with units made by Yujingguang. It’s not yet known whether the company will be able to fix the problem in time for the launch. While Apple will undoubtedly not be impressed by the failure in the iPhone 12 camera lenses, there may be an upside to it. Kuo believes that the lens supplier will be forced to offer Apple a substantial discount on the agreed price in order to win back the business.

Twitter pushed an iPhone release suggesting that the ability to limit who replies was being rolled out more widely than it currently has been. However, The Verge found out that the release notes came out by mistake.

Twitter has been experimenting with this feature since May, and yesterday pushed an update to the iPhone version of its mobile app suggesting the feature would be more widely rolling out. A Twitter spokesperson now tells The Verge it accidentally pushed incorrect release notes; the feature is not in fact more widely rolling out, for now. “In May, we tested a new way to have a chat with exactly who you want, so you can create and consume more meaningful changes,” read the update text on the App Store. “Now, everyone can try this new feature and choose who can reply to their tweets.” A Twitter spokesperson says the misconception was due “to some accidentally pushed release notes,” and that “the ability to limit replies on tweets is not currently available to everyone.”

Tudor Brown, the former president of UK chip-designer Arm, has warned against the sale of the company. There has been speculation current owner Softbank will sell it to Nvidia. Mr. Brown voiced his opposition to such a move in an interview with BBC News.

“I have always believed the Softbank investment and focus on growth was ill-advised, and I think Softbank is coming to accept that now,” Mr Brown told the BBC. “[But] it would be very bad news for ARM to be sold to any semiconductor company. “The company should be slimmed down and kept independent to serve the industry from a profitable position of neutrality.” ARM creates computer-chip designs that others then customise to their own ends. It also develops instruction sets, which define how software controls processors.
