The Sony SmartWatch recently received a major new update that brought amongst other things the watch face being visible at all times. However, this update (software version 1.2.33) brought with it a number of issues for some users including constant disconnections. A recent bug fix updated the firmware to version 1.2.34, but many users are still reporting similar problems.
Sony Mobile says it is aware of the issue that some people are having and recently released this statement over on the SM Product Blog:
