Notes Android - How to handwrite / take notes in Chinese

This instruction is written based on experience using the following phablet:

However, the instructions may also work for similar Android smartphones.

This note will show how to use the phablet to take notes in:
English - via keyboard,
English - via hand write
Chinese - via keyboard
Chinese - via hand write

Prerequisite apps:
Google Keep - this is a note taking app which is quite flexible. Users may choose other editors.

Change Language Settings:

- Under "Keyboard & Input Methods", tap Default
- A window pops up with the following choices.
----- For international Xperia keyboard
----- Xperia Chinese Keyboard (Choose this if you want Chinese)
----- International Keyboard   (Default, for English)

Using English Keyboard or Handwrite
- Open up Google Keep or another notepad-like editor app.
- Start writing the note and activate the keyboard.
- WARNING: to write in English, the "Xperia Chinese Keyboard" also has an English option but don't use this. Instead, for English, choose "International Keyboard" in the Language settings section above.
- Look at the keys at the botton row, and find the key marked "EN" for English or "CN" for Chinese.
- Toggle this buttion to get "EN" for English, if it is not EN already.
- Tap and hold the EN key for a few seconds, to switch between Keyboard mode or hand-writing mode.

Using Chinese Keyboard or Handwrite
- Open up Google Keep or another notepad-like editor app.
- Start writing the note and activate the keyboard.

Tricky important note is that, once in a chosen language already, changing from stroke to hand-writing requires tapping and holding on the language button, eg "EN". Different models may have different option names for handwriting or using keyboard.

Notes Android Directory Structure

This post is about the native directory folder structure of Android. This means for a phone, tablet, phablet, smartphone, etc which runs a modern Android OS (current latest is 4.4), their internal directory folder structure is the topic of this post.

The way to see the directory is to use various apps such as "File Manager", "File Commander" or other similar applications. This post aims to describe the common folder structure so it is easy to find things when we know it.

When new apps are installed, many would have their own folder created under the top level directory. Besides apps, there will be an existing number of folders following a new installation of Android.


The directory / folder structure is like:

Alarms
amazon ------------- your own app
Android
-- data
-- obb
..........
burstlyImageCache
burstlyVideoCache
DCIM --------------- images taken with camera usually goes here by default
-- .thumbnails
-- 100ANDRO
-- Camera
Download ----------- downloaded files usually go here by default
kindle ------------- your own app
Music
