@ Description:
  We got complaints from our end-users.
  We sell low-end device and there is insufficient hardware resources.
  When device application storage is less than 5 MB. By current design (Bug 861921), system will display warning message of insufficient storage, and then lock indexedDB and enable airplane mode.
  After that, many core functionalities cannot work.
  1) User cannot make a phone call.
  2) User cannot send SMS
  3) User cannot use data network
  4) All system settings cannot be modified/changed via Settings app
  5) Contact cannot be saved.
  6) etc...

  As a user, it seems to be unreasonable.
  
@ Reproduction step:
  1. Use command below to push data to device till application storage is less than 5 MB.
     $ adb push "FILE_NAME" /data/
     * Note: Normal user path: Sync facebook friends, or scan music of SD card. It will occupy application storage.

  2. Make a phone call, send SMS, etc..., when application storage is less than 5 MB.

@ Actual result:
  1. User CANNOT make a phone call or send SMS.

@ Expected result:
  1. User can make a phone call and use preload applications. (TBC. Need UX to review)

I have checked this problem on Flame 2.1, Flame 2.2 and Flame 3.0, the results are as follow:
* Flame 2.1/2.2/3.0(Application storage is less than 5 MB).
1. User can make a phone call normally.
2. User cannot send SMS, compose a message and tap "Send" icon, it will pop up: "Message not sent, There was a problem sending the message. Please try again."
3. User cannot use data network, after turning on Data connection, it will turn off automatically.
4. All system settings cannot be modified/changed via Settings app
5. Contact cannot be saved, on "Add contact" screen, tap "Done" button, device has no response.

Hi all,

Matej did a string review and we have an update. 
IxD and VsD Specs will be updated to reflect this change.

Please update strings from 'Low Device Storage' to 'Critically Low Storage'

Impacts:
• Settings App: Application Storage, Media Storage & App Permission
• System App: Lockscreen, System Toast & Utility Tray Notifications
• Message App: Low Storage Notice
• Dialer App: Low Storage Notice and Incoming/Outgoing Call Notifications
