Related: Wear OS improvements


As with Android OS 8.0, the LG-W280 Watch Sport was amontg the first to get the Wear OS public release.

Google’s list of watches that already have OS 8.0 are generally getting Wear OS.
Noticeably missing is the LG-W200 Watch Urbane 2nd Edition LTE.

New features

Wear OS performance and visible improvements over and above prior Android Wear improvements include:

  • Touch Lock: distinct from Theatre mode (which disables notification display), touch lock disables touch-to-wake while still allowing notifications to display.
  • Battery saver: user-switchable under System → Battery Saver. Previously, Battery Saver would come on automatically at 15 % battery, and there was no way to turn on Battery Saver manually. Wear OS battery saver enacts:
    • vibration disable
    • limits location services/Wifi/cellular usage
    • no app updates
    • reduces display brightness
  • Auto Do Not Disturb when off wrist. The watch won’t buzz (vibrate) annoyingly on your nightstand or desk, while you can choose to allow: Alarms, Favorites, Reminders, Events.
  • Require SIM lock option–you can choose to require a SIM password.
  • Notification channels–control notifications on a per-app basis.

Notes

Force reboot

My LG-W280 stuck at “preparing to upgrade” at 2 % progress for many hours. I force rebooted the watch by:

  1. press & hold the side center button for 10 seconds. The watch will make a long vibration, keep pressing until this vibration stops.
  2. If you get a broken Android logo with a triangle orange exclamation mark, Force reboot once more.

Now you should have fallen back to the previous Android OS 7.1 on your smartwatch. The next day, Android OS 8.0 installed OTA automatically and correctly.

Android OS 8.0

Android 8.0 for Wear was released to the general public on Dec. 6, 2017. Wear OS was released March 15, 2018. This obsolete Android 8.0 Wear beta info is retained for reference.

Upgrading to Android 8.0 for Wear was done OTA (over-the-air) by simply requesting beta access. Approval was instant for LG Watch Sport W280 users in the USA, and that same night I got the automatic Oreo OTA.
