Android 4.4 KitKat: External SD Card not writable

One reason why a love Android is because you easily can expand memory by a large external SD Card (and by USB devices….).

With Android 4.4 “KitKat” Google has (tacitly) decided to de-value this feature by making the “external” SD card only readable by all applications, but writable only in a very restrictive way i.e. temporarily for single applications but not for multiple apps to share storage between them. Google thinks this kind of “sharing” should only be done by cloud services and thus requires permanent internet access, whereever you are in this world…

Test: Use “Ghost Commander” and try to copy files from “/storage/sdcard” (internal storage) to “/storage/sdcard1” (external SD card)……

The easy way: Android 5 Lollipop

I decided to upgrade my Android 4.4 to Android 5 (Lollipop).

In Lollipop Google has opened again write acces to the external SD card, but you must in some way “allow” each App, what directories of the SD card should be writable for this application.

  • Ghost Commander:  not successful on first attempt
  • File Commender:      successful with Lollipop
  • ES Datei Explorer:     successfull with lollipop (after authorizing SD card root)
  • X-plore:                   successfull with lollipop (after authorizing SD card root)

Possible Fixes

There a some Apps around that could fix this “Google Feature”, but they need a rooted Android.

So I am an now looking how to root my Sony Xperia Z1 Compact.

My Build No. is  14.4.A.0.157   (the “Kernel”, the “ROM”)

Rooting is possible only with Build 14.4.A.0.108   -> Have to flash the kernel first (with “FlashTool”)

First Steps

Developper Mode: Settings -> About -> Build Number  —- Tap 7 times on “Build Number” —> Now you are a “Developer”

USB Debugging: Once you are “Developer” you can see the item “Developer Options” under “Settings -> System”. Check “USB Debugging” and authorize it….

Replacing my iPhone by a Android Smartphone: Sony Xperia Z1 Compact

My Situation: iPhone fallen into water

My beloved iPhone 5S has accitentally fallen into water for some 3-4 seconds.
As a result the iPhone is definitly DEAD and the only Apple Solution possible is the use the Apple Change Service i.e. pay EUR 200 for a replacement.
I chosed not to to this but to understand this accident as my chance to move to Android.

My Requirements

Lookig for a quick replacement for my brocken iPhone, I first put together my top requirements:

  • Form factor should be “flat back side”   (in order to be able to attach the phone to my astronomical equipment)
  • Size of display max 5 inches
  • the battary should be replacable
  • must have a slot for a SD card  (min. 64 GB)
  • must have a USB host (or OTG) slot
  • must have good sensors: magnetometer, gyroscope,….   (for astronomical positioning at celestial bodies, must have some way to calibrate)
  • should be “waterproof”
  • as a matter of course: Internal storage min. 16 GB, WiFi, GPS, Bluetooth, LTE,…
  • astronomical apps with Polar finder / Polar alignment

 My Short List and my evaluation

  • Sony Xperia Z3 Compact
  • Sony Xperia Z1 Compact
  • HTC One Mini 2
  • Samsung Galaxy S4 Mini
  • ….

The HTC was excluded first.
The Samsung Galaxy S4 Mini was favoured because of the replaceable battery, but it did not support USB OTG, which is a NO-GO for me.
At the end, the Sony Xperia Z1 Compact was choosen although is does not have a “replaceable” battery but it fits best with all the other requirements and the built-in battery is reported to be very good and some replacement by a specialized shop should be possible.

Shopping 21.4.2015

In Hamburg I found the Sony Xperia Z1 Compact at “Saturn” for EUR 279, but they did not have it in stock.
At the “Media Markt” shop in Hamburg the Z1 Compact was also on the shelves with the same price tag.
On my way from “Saturn” to the subway station Jungfernstieg  I passed through the “Europa Passage” where I found a Cyberport store which had the Z1 Compact in stock and sold it for EUR 272 (21.4.2015).

First Steps

  1. Charge the Z1 for 2 hours
  2. configure WiFi connection
  3. Insert the Micro SIM card (from the iPhone) – this was a some what complicated procedure, since Sony’s documentation was bad, and only hints from the Internet helped after all.
  4. Configure Email account  (IMAP at Strato)
  5. In order to access Googles Play Store: establish a general Google account for this device. I used the account I had already on my old Android tablet the Acer Tab A500. This allows me use reuse Apps on the new Z1 Compact
  6. Google Play Store: Download “CardDAV Sync free“
  7. Create CardDAV account for my addressbook, which I host internally on my WHS2011 Home Server with Baikal. Synchronize “one way”. This populates the standard Android contacts with my Baikal contact addresses. So the only “extra” piece of software is that “sync piece”. After that the rest is Android standard.
  8. Test the integration of the these new contacts with the Android email App. It works, the email App uses the Contacts when writing new messages….
  9. Google Play Store: Download “CalDAV Sync”   (not free, but was already boughdroid tablet with the same Google account)
  10. Create CalDAV account for my calendars, which I host internally on my WHS2011 Home Server with Baikal. Synchronize “one way”. This populates the standard Android calendar with my Baikal calendar entries. So the only “extra” piece of software is that “sync piece”. After that the rest is Android standard.
  11. Test the integration of the Android calendar App with the contacts. It works, the calendar App offers the contacts when creating new “invites”.
  12. Google Play Store: Webradio App “TuneIn“
  13. Configure the pre-installed “WhatsApp” with the same telephone number I had on my broken iPhone. WhatsApp detcted that and reported I have now 7 free months remaining (out of the initial 12 free months)
  14. Google Play Store: “WiFi Manger”   (in order to see all the WiFi/WLANs in my neibourhood)    —> Widget ???
  15. Configure the pre-installed “OneDrive“
  16. With OneDrive I have access to my Excel-, Word- and PowerPoint documents. OneDrives asks me to install “Office Mobile” what I did…..
  17. Google Play Store: App “Skype“
  18. Configure pre-installed App “Evernote“. Sony and Deutsche Telekom (my SIM car) where so kind to gant me a a 12 months premium account for free. But this resulted in a new Evernote account, based on my Goolge ID on that phone. I got an email that allowd me to configure a password for that new Evernote account.
  19. In order to use the Evernote premium account, I exported all my Evernote Notebooks from my “normal” Evernote account and subsequently imported them into the new Evernote premium account  (don’t forget synchronisation….)
  20. Bought a new SD card for the Z1 Compact: SanDisk Extreme microSDXC UHS-I  with 64 GB capacity and a speed “up to” 60 MB/s   (on reading, I assume – and 40 MB/s for writing says the small print)
  21. Bought a protective cover “Slim Office Case VM-361” by “V-Desgn”  www.vdde.eu ) for the brand new Xperia Z1 Compact
  22. Google Play Store download: astronomical App “SyEye“
  23. Google Play Store update: “Google Maps“
  24. Google Play Store download: astronomical App “Google Sky Maps“

Notiz: Background of the Fax Industry

Background on the Fax Industry

The facsimile was invented in 1843 by Alexander Bain, earlier than the telephone invented by Bell in 1876. The facsimile came into practical use much more slowly than did the telephone. Using early achievements in electronic engineering such as the vacuum tube and photo cell, practical models were developed in the 1920’s in the United States, Germany, France, and Japan. After their introductions, facsimile apparatuses were used in specialized areas, such as for transmission of news pictures and weather maps, and pickup and delivery of telegrams.
Facsimiles are classified into either photographic facsimile, in which the original copy is reproduced faithfully with graded tonal densities, or document facsimile, in which the original copy is reproduced primarily with black and white.For many years before the growth of the fax machines, Alexander Bain modified a system of synchronized electric clocks to make the first fax machine. He devised a way of skimming raised metallic letters with a stylus attached to a pendulum. With this method, a stream of electric pulses were sent by a wire to the receiving device where a second synchronized pendulum swept across chemically-treated paper, leaving a dark mark wherever a pulse occurred. The rate at which the apparatus was capable of working was discovered accidentally by a broken spring. The fax principle was established and Bain received 7,000 for his telegraphic patent. The money he received was wasted in litigation and he died a poor man.

After the death of Bain, a handful of European inventors began to build upon his non-success and refine the fax principle. Giovanni Caselli, Frederick Bakewell, Ludovic d’Arlincourt and Edouard Belin each contributed innovations, but it was not until 1902 that Arthur Korn, a German, demonstrated the first photo-electric scanning fax system. The previous methods had depended upon Bain’s contact-scanning technique. In 1902, Dr. Arthur Korn developed a photoelectric scanning system for the transmission and reproduction of photography, and in 1907, he established a commercial picture transmission system. This system eventually linked Berlin, London and Paris and became the world’s first facsimile network. Facsimile then made slow but steady progress through the ‘20s and ‘30s, and in 1934 the Associated Press introduced a wire photo service. Korn’s breakthrough of giving the fax machine “sight” prompted serious commercial experimentation by three American telecommunications giants: AT&T, RCA and Western Union. Korn’s success and achievement in using the fax brought new development and direction for broadcast publishing to the United States.
