Sony now allows users of the SmartWatch to create their own firmware to install on their devices. Users have been able to use specially designed firmware to do things like change the clock face. Now, it is possible to create your own custom firmware to do everything from change your watch face to run the device.
If you intend to run your own firmware on your SmartWatch, you should be an experienced developer. There are risks involved when using alternative firmware on a SmartWatch. When you use custom designed firmware, your SmartWatch will no longer run as it was designed. The use of the SmartConnect feature as well as any SmartWatch app available on Google Play will be restricted as well. Additionally, any warranty on the device may be voided when you use custom firmware on your SmartWatch.
The firmware that runs your SmartWatch is fine-tuned to run it and help it communicate with other compatible apps. By creating alternative firmware, you are taking control of the device. For the average consumer, there is no need to create and use custom firmware because of the risks involved. As stated, if you are an experienced developer you may wish to create and use your own alternative firmware.
