FORTUNE -- Having written twice about the problems I've had getting the iPhone 5S to recognize my scarred left thumbprint -- and to remember it two days later -- I'm happy to report that TouchID is working for me now.
I don't know whether to thank the "overtraining" trick I picked up a couple weeks ago or the iOS 7.1 software update that Apple (AAPL) released on Monday, but for me TouchID's reliability has increased significantly, from an unworkable 50% to close to 100%.
Your mileage may vary. In fact, some iPhone 5S owners are complaining on Apple's support site that for them, the update backfired. As of Wednesday morning, Touch ID doesn't work after iOS 7.1 Update had drawn 25 responses and more than 2,000 views.
To try to quantify the extent of the problem, how about a quick, totally unscientific poll?
That's the claim being made for the fingerprint scanner in the upcoming Galaxy S5.
FORTUNE -- Here's the challenge: To be incorporated as part of a regular start-up routine, fingerprint ID systems must be at least as easy and dependable as the pass codes they are meant to replace.
Which is why I finally gave up trying to use Apple's (AAPL) TouchID system on my iPhone 5S.
Not that I'm a good test case. After 64 years of paper cuts, MOREPhilip Elmer-DeWitt - Feb 18, 2014 11:24 AM ET
Get out your handkerchiefs for Apple's annual holiday "home movie."
FORTUNE -- What would the holidays be without a sentimental Christmas ad from Apple (AAPL)?
This one, titled Misunderstood, is a movie about a movie that was shot on an iPhone 5S and presented via Apple TV and AirPlay by the fictional Harris family's teenage son. The title is not explained. Perhaps it's a given that all teenage sons feel misunderstood, especially MOREPhilip Elmer-DeWitt - Dec 17, 2013 7:37 AM ET
In six hours Thursday, the visitor counter on this website grew by more than 14,500.
FORTUNE -- Some time before midnight in New York (1 p.m. Beijing), China Mobile's (CHL) Beijing reservation website switched to attached image, strongly suggesting that the world's largest mobile carrier -- with more than 750 million subscribers -- was getting ready to offer Apple's (AAPL) iPhone 5S for sale.
"Something worth waiting for," reads the banner, according MOREPhilip Elmer-DeWitt - Dec 12, 2013 6:28 AM ET
By Dec. 4, the iPhone 5S was available in all 60 U.S. stores surveyed by Piper Jaffray.
FORTUNE -- In early October, two weeks after Apple (AAPL) released the iPhone 5S, the device was out of stock at 92% of the 60 U.S. stores surveyed by Piper Jaffray's Gene Munster.
Piper Jaffray has been checking the stores twice a week ever since, and on Monday Munster announced in a note to clients MOREPhilip Elmer-DeWitt - Dec 9, 2013 9:35 AM ET
Kantar reports that nearly half were switching from other brands, chiefly Samsung and LG.
FORTUNE -- When Apple (AAPL) released a pair of new iPhones in September, demand was so lopsided in favor of the more expensive (by $100) model that many on Wall Street assumed that the pricing on the cheaper iPhone was some kind of blunder.
The iPhone 5S continues to outsell its more moderately price sibling -- by three to one in MOREPhilip Elmer-DeWitt - Dec 2, 2013 2:05 PM ET
Who says Apple priced itself out of the Indian smartphone market?
FORTUNE -- Apple (AAPL) launched the iPhone 5S and iPhone 5C in India three weeks ago -- a month and a half after their initial release in 11 other countries.
Early reports suggested that the new iPhones were off to a strong start, but it wasn't until I read The Indian Express' follow-up Monday that I thought to see if there were MOREPhilip Elmer-DeWitt - Nov 26, 2013 11:07 AM ET
Mordy Tikotzky's iPad Air tracker showed which stores had them in stock. Apple killed it.
FORTUNE -- I confessed my fascination with Mordy Tikotzky's Apple-Tracker.com when I posted a story about it earlier this week.
Tikotzky had written a handy little widget that steered customers to the Apple Stores in or near their Zip Code most likely to have the newest iPhones and iPads in stock.
It also offered Apple (AAPL) watchers like me a MOREPhilip Elmer-DeWitt - Nov 6, 2013 7:47 AM ET
Dueling reports Monday on how much better the high-end model is doing than the low.
FORTUNE -- When the iPhone 5S and 5C went on sale last month, there was every reason to suspect that the more advanced 5S would draw more early adopters to the Apple (AAPL) stores than the 5C. And indeed, by one launch-day line count, the iPhone 5S buyers outnumbered 5C buyers that first day by 20 MOREPhilip Elmer-DeWitt - Oct 14, 2013 8:40 AM ET
Only Samsung's Galaxy S4 is outselling the iPhone 5C, and only at Verizon and T-Mobile.
FORTUNE -- "Our September surveys indicated very strong initial sales and back orders for the iPhone 5s and strong iPhone 5c sales at the four tier-1 U.S. carriers and also in international markets."
So wrote Canaccord Genuity's T. Michael Walkley in a note to clients Friday that included the first published chart of where Apple's (AAPL) new MOREPhilip Elmer-DeWitt - Oct 6, 2013 6:10 AM ET
