Sometimes the world stands upside down

iPhones feature a number of sensors, which are used to adjust the screen based on operating conditions, enable motion-controlled games, location-based services, unlock the phone, and authenticate purchases with Apple Pay, among many other things.

Here are the sensors …


Audio input, Proximity sensor, Ambient light sensor, Water damage indicator, Barometer


Accelerometer, Magnetometer, Gravity sensor, Gyroscopic sensor


Fingerprint sensor or Camera for facial recognition

and last but not least the Accelerometer part of the device-motion information .

The 3-axis accelerometer senses the orientation of the phone, forwards it to iOS which then changes the screen accordingly, allowing the user to easily switch between portrait and landscape mode. Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so.

Your Google+ app doesn’t support screen-rotating so you can easily read the twisted message at the top of my post.

For the nerds who like to control everything the app Sensor Kinetics by Innoventions Inc, available at the App Store, might help.

Keep up your body and your thoughts.

iPhone 6s Plus camera and flashlight

I took this shot of a wooden mask from Hongkong in an absolutely dark room using the iPhone’s flashlight. Less reflections. Unbelievable for a 2 year old device.

I don’t really think that the image quality of a 7, 8, or X would be significantly higher.

Hard Work

2 05 2018

It’s hard work not only for me (to update our driveway) but also for my iPhone 6s Plus running in a moist environment with temperatures above 35C (95F).

I never got the warning

“iPhone needs to cool down before you can use it”

the sensors forward to iOS if an iPhone feels bad.

It’s why I remove the Apple Silicon Case if it’s getting hotter and hotter at noontime. It wouldn’t be that big deal if the device shuts down but you would have a severe problem if the Li-Ion battery gets too hot. So watch out when making holidays in hot countries.

LIAM – An Innovation Story

24 04 2018

Apple’s 26-armed robotic cutting tool
that removes valuable materials from iPhones

Liam has the potential to recover materials for every 100,000 iPhone 6 devices:

Aluminum 1900 kg, Gold 1.3 kg, Silver 7 kg, Rare Earth Elements 24 kg, Tungsten 3.5 kg, Copper 800 kg, Platinum Group, Metals 0.4 kg, Tin 55 kg, Cobalt 550 kg, Tantalum 2.5 kg.

So Apple is on the way to a closed loop but it will still take a long time to produce “zero waste” devices.

Sustainable recycling …

It’s not to be had for nothing.

We have to pay a lot more for products which are made without taking finite resources from the earth.

The industry follows lots of technological standards but I don’t see any initiative of the big manufacturers of eWaste to create a consortium which establishes rules for making eco-sensitive products (e.g. without chargers as an option, replaceable batteries, etc). The focus is still on making money. Adding more and more Smart Home Products needing more and more resources is not so smart as the industry likes to tell us.

Calendar Attachments

17 04 2018

In some cases I’d d like to add one or more attachments to a calendar event, e.g. a JPEG, a PDF, a Pages, or an Excel document with more detailed information about it.

In my example I added the application form (PDF) to prolong my retirement visa for Thailand.

This is neither an option in Apple’s app Calendar nor in the calendar feature of Microsoft’s app Outlook. Only Google Calendar provides an option to add an attachment (from Google Drive) regardless of its file format.

Dear iOS developers,

please implement an option to add an
attachment via Files to calendar events.


If you would also like to see this feature in an updated Calendar app please send feedback on

Thai Limes

10 04 2018

A Lime ( มะนาว ) is a hybrid citrus fruit, which is typically round, lime green, 3–6 centimetres (1.2–2.4 in) in diameter, and contains acidic juice vesicles. The photo I took with my iPhone 6s Plus shows limes in our garden near Khon Kaen, Thailand, an essential ingredient for the delicious food my wife หนูพัศ cooks.

The health benefits of lime include weight loss, improved digestion, reduced respiratory and urinary disorders, relief from constipation, and treatment of scurvy, piles, peptic ulcer, gout, and gums. It also aids in skin care and eye care.

What about the botanical name of our limes?

I suggest Thai Limes, which may be vague, but which gets the point across. Because the semantics of what’s in the garden matters, as does the semantics of what goes into that gloriously fragrant pot of Tom Kha Gai on your stove or a spicy (เผ็ดร้อน) papaya salad (ส้มตำ).

Btw, it’s definitely not true that taking pictures of food is almost as much fun as eating it.

Thinking about the delicious Thai Food sometimes let you forget what your post is about. So back to my iThing.

With a perfect lighting my iPhone 6s Plus makes amazingly good photos. Just focus on the limes or leafs and zoom in.

The image sharpness remains quite good.

At the time I don’t think about purchasing a new iPhone. The 7/8/X might have better cameras but for me the imagination and remembrance linked with images are more important than their quality (if it’s not too bad).

Vilfredo Pareto and iOS 12

2 04 2018

The Pareto Principle
A guideline for iOS 12 development
Thumbs down for feature proliferation

The Pareto principle, also known as the 80-20 Rule states that roughly only 20% of the causes affect 80% of the effects. Applied to iOS it would mean that just 20% of the bugs cause 80% of all errors. That’s at least what Microsoft found out with an error-reporting tool embedded in Windows and Office.

iOS 11 development and maintenance was a rocky road for both Apple and its customers.

Released on September 19, 2017 we had iOS 11, 11.0.1, 11.0.2, 11.0.3, 11.1, 11.1.1, 11.1.2, 11.2, 11.2.1, 11.2.2, 11.2.5, 11.2.6 as of March 9, 2018.

So iOS 12 is going to be an update that focuses heavily on bug fixes and refinements to the underlying code. According to Bloomberg, Apple was originally planning to introduce features that included a refresh of the Home screen with a redesigned app grid, a revamped CarPlay interface, improvements to core apps like Mail, and updates to picture-taking, photo editing, and photo sharing, but the company has opted to delay these features until 2019 in order to focus more heavily on making iPhones more responsive and less prone to cause customer support issues.

It shouldn’t be that difficult for Apple’s developers and testers to find that bugging 20% in their i -buggy- OS if the management successfully revamped the flow of operations.

But …

What’s forgotten is that these 20% are often the most complex, most difficult issues to correct and the most likely to spawn new problems as part of the correction process.

Now it’s your turn Craig (@HairForceOne) Federighi. Inner values count. Force your devs to make iOS 12 bulletproof.

More about the Pareto Principle


Don’t ask me wether it’s true that 80% of a swimming iPhone X is below, while only 20% is visible above the surface.

Thanks for reading.
iOS 12. Let’s keep our fingers crossed.
