[Discussion] All About OTA update

Hi Mi Fans
Hope you are all well

Mobile technology is now developed a lot. It must be running an operating system for seamless working collaborating with the hardware specs. Every time when a security patch or any specific system update is required, then the OEMs pushes an OTA update to its users.

In this thread, we are going to learn about OTA update
What is OTA?
OTA (Over-the-Air)  update refers to various methods of distributing new software, configuration settings, and even updating encryption keys to devices like mobile, set-top boxes or secure voice communication equipment.

Types of OTA:

  • A/B (seamless) system updates

New Technology mobile devices run on A/B partition. A/B devices have two copies of each partition - A and B. Devices apply the OTA update to the currently unused partition while the system is running but idle. A/B devices do not need space to download the update package because they can apply the update as they read it from the network. A/B updates are also known as seamless updates.

  • Non-A/B system updates
Older devices have a special recovery partition containing the software needed to unpack a downloaded update package and apply the update to the other partitions.

How does OTA work?

The OTA process is self-explanatory in that it delivers updated software wirelessly or ‘over the air’. These updates are distributed over WiFi or mobile broadband using a function built into the smartphone or mobile device operating system or through a special OTA app that’s given root access. The update goes out to all the designated smartphones or mobile devices from one central control panel server.



Following are the way by which the update will be applied:

  • The end user gets notified about an available update and accepts the firmware update on their smartphone or tablet after which the new firmware is sent over. With this option, the end user also has the option to refuse the update.
  • The firmware update can be pushed through by the channel manager automatically. This option can be useful for a device that is in a remote location or a device that might not have a touchscreen, buttons or hardware input

What can OTA do?

  • System Updates: System updates can be done through OTA, provided that the chipset being used in the device can support an updated operating system, then OTA can be used to send these updates. For example, if you have an Android device on the market using Android 6.0, with OTA you can send Android 7.0 straight to the end user’s tablet. This also works for behind the scenes security updates, bug fixes, or other improvements to the software.


  • Fix Bugs: Software will always have bugs. Some are minor bugs, some are not. Bugs are not always found and removed or fixed before a product has been distributed. There are some bugs that could cause a recall for all the devices, however, with OTA this would not be necessary as the bug can be fixed and the updated firmware sent to each device.


  • Add/Remove APPs: There is a silent install feature using OTA where an APP can be sent to a device to be downloaded or the user could choose to download a new app. OTA can also be used to remove an APP that may not be wanted any longer.


  • User Interface and New Features: OTA can allow you to update and change the user interface or add new features to your devices.


Conclusion

In general, It refers to the wireless delivery of new or updated software or firmware to devices such as smartphones and tablets.
  • OTA can be used with Android, Apple, Microsoft, and virtually all other connected devices (such as tablets, smartphones, PC’s, and IoT devices).
  • It is always recommended to update when the OTA update is available for your device which can consist a number of a patch for fixing a bug, security update etc.
  • It is always recommended to take a backup your valuable data before starting the update.
