simplicity is key:

what is definately great and a big plus is the “openness” of the Android (a by Google heavily modified GNU-Linux) environment.

no need for extra software (itunes) to access the device
- a usb-c-cable will do
  - connect it
  - then on drag-down-menu tap “charge device” and change the mode to “file transfer” dada!
  - now the Android Phone behaves like a usb-stick and can be accessed from any GNU-Linux, OSX and even Windows, HURRAY! 🙂 (that is exactly that kind of simplicity that everyone should want))

app extractor

a genious app that allows sharing installed apps with other Android devices

also it:

actually gives a more complete list of all apps installed on a device
allows to pack any installed app into a name.apk file to be send via bluetooth or messenger or downloaded to PC via wifi/wlan
- via bluetooth used to work, but increased security restrictions this could fail
  - workaround: get an USB-C capable USB stick 🙂
  - or use a PC and a USB-C cable
  - or use the wireless access method to copy files

access to Android devices via SFTP (encrypted FTP) allows this genious app:

make sure PC and Android Device are in the same LAN-WIFI and subnet

install it
start it
go to settings
tap on username (default is: user)
tap on password (set a strong password of at leat 10 chars: UPPER LETTERS lower letters numbers and special chars)
tap on port (ftp default 12345 sftp 1234) (change or leave it like that)
tap on what server to start (disable ftp)
leave settings
click on “Play” button on top right
- the “PrimitiveFTPd” will display IPv4 and IPv6 address on the top
install and start https://filezilla-project.org/
- apt install filezilla
Filezilla:
- new connection
- select SFTP
- type in IPv4 as displayed in “PrimitiveFTPd” on top
- type username: user
- type in set password
- click connect
- it should ask “do you trust key X”, check the Box “always trust this key” and hit OK
- now it should display the contents of the device root folder and allow up and download as well as creating new directories 🙂
- HURRAY!
