An Apple a Day: Woz Has Some Advice for Apple by Don Reisinger @FortuneMagazine August 27, 2016, 9:40 AM EDT E-mail Tweet Facebook Linkedin Share icons An Apple a Day is a weekly roundup of the biggest Apple news this week. To see last week’s roundup, click here. It’s been a busy week for Apple. Over the last several days, Apple AAPL has been forced to defend against a potential cyberthreat to its mobile operating system iOS, hear claims that the same operating system is suffering from more “failures” than ever, and keep consumers guessing at what it has planned for its next iPhone. Along the way, we’ve heard talk of Apple working on a Snapchat clone and seen evidence that the iPhone maker is by far the best in the business at making a profit on smartphones. This week has also been one for celebration. On Wednesday, Tim Cook celebrated his fifth anniversary as Apple’s CEO. Get Data Sheet, Fortune’s technology newsletter In sum, we might be in the late, lazy days of summer, but there’s no slowing down Apple news. Read on to find out what happened this week in Apple’s universe: Steve Wozniak warned Apple this week that if it decides to remove the headphone jack in the iPhone 7, it could “tick off a lot of people.” Wozniak, who was speaking to the Australian Financial Review, was responding to reports that Apple’s next iPhone, believed to be known as the iPhone 7, could come with dual speaker grills that would force the company to remove its headphone jack. It would be the first time Apple would not offer a headphone jack in an iPhone. For the first time ever, Apple’s iOS “failure rate,” which measures when apps crash and other glitches occur within the operating system, was higher than Android’s, according to mobile technology service provider Blancco Technology Group (BTG). During the second quarter, 58% of the millions of iOS devices BTG analyzed suffered at least one “performance failure,” up from 25% in the first quarter. Android’s failure rate was 35% during the period. Apple could be planning a new way to stop thieves from stealing your iPhone. The U.S. Patent and Trademark Office on Thursday published an Apple patent application that would collect a person’s fingerprint and even snap photos and video of them, if they’re deemed an unauthorized user. The technology would then distribute that data to the owner to send off to law enforcement. Apple is said to be working on a new quick-video-sharing app that would mimic features users already find in Snapchat, Bloomberg is reporting. The company’s secret app that would allow users to snap video, add filters and other effects to the clips, and share them via social media within one minute. The app could launch next year, but will need to make it through Apple’s rigorous standards testing before getting the green light. On Wednesday, Apple CEO Tim Cook celebrated his fifth anniversary as the company’s chief executive. Although his appointment to CEO came at a troubling time for Apple as its co-founder and then-CEO Steve Jobs was battling cancer, Cook took the helm and has remained in the position ever since. Fortune looked at some of the highlights (and lowlights) of his time as Apple’s CEO to commemorate his fifth anniversary. In a separate evaluation, Fortune gave Cook a “B+” so far as Apple CEO. Canaccord Genuity analyst Mike Walker revealed this week what many had suspected for a long time: only Apple and Samsung know how to make a profit on smartphones. His findings, which were based on company filings and his own estimates, found that Apple generated a 38% operating margin on every iPhone it sold in the second quarter. Samsung was able to nab a 17% operating margin on smartphone sales during the second quarter. Every other major smartphone maker either lost money on each smartphone sale or broke even. Collectively, Apple and Samsung generate all of the smartphone market’s profits. If you’re a Samsung Galaxy S7 Edge or Galaxy Note7 user, this might be old news, but Apple is reportedly planning to deliver a curved screen in next year’s iPhone. The feature would be similar to the curved displays in the aforementioned Samsung smartphones and accompany standard 4.7- and 5.5-inch iPhone displays. It’s possible, according to source speaking to Nikkei, that the curved-screen iPhone could feature a screen larger than 5.5 inches. On Monday, Fortune conducted an in-depth analysis on why an Apple I computer likely built in 1976 could be worth as much as $1 million. The computer, called a “unicorn” by Apple historian Corey Cohen, was one of the first Apple I computers ever built, and could be the first Apple I prototype. However, at its auction on Charitybuzz, the computer sold for $815,000 to Glamglow co-founders Glenn and Shannon Dellimore. They plan to bring it to museums and universities around the globe to educate people about Apple’s history. Apple acquired a small health startup this week named Gliimpse for an undisclosed sum. Gliimpse was founded in Silicon Valley in 2013 with the goal to create “personalized and shareable medical records” for every American. The company’s product tracks everything from heart rate to Potassium levels and gives both doctors and patients a clear view into the patient’s health history. It’s part of an effort at Apple to broaden its service to the healthcare industry. Universal Music is said to have decided that it will no longer offer exclusive access to its material to Apple Music, according to a report. The company had previously offered Apple Music exclusives before expanding streaming rights to other services, like Spotify, but has reportedly decided against the move. Apple has used exclusives to acquire more users and differentiate its services from Spotify and others. Apple CEO Tim Cook held a fundraiser for Democratic Presidential nominee Hillary Clinton this week. Tickets to attend the event reportedly went for as much as $50,000. The event was held after Cook earlier this year held a fundraiser for Republican House Speaker Paul Ryan. He has denied fundraisers to Republican Presidential nominee Donald Trump. For more about iPhone, watch: One more thing…If you haven’t already, now is a very good time to download Apple’s latest iOS update, iOS 9.3.5. The software was released on Thursday and patches a software flaw in earlier iOS versions that allows hackers to install spyware on iPhones and iPads, and steal a device’s content and data. The flaw was uncovered by security researchers who discovered hackers had tried to install the spyware on a United Arab Emirates human rights activist’s iOS device. It’s unarguably one of the most critical iOS updates Apple has ever released.
