Related: Upgrade Wear OS
Wear OS watches benefit from prompt updates provided through the Wear OS app. When an update is available, you’ll get notified with a watch card.
- Wear OS updates enable even more features, but rely on the watch OEM getting involved
- Wear OS updates can also add new features, and come quickly because they’re just throught the watch Play store, the OEM does not need to be involved.
- Wear OS is like what would have been Android Wear 3.0
|Wear OS||Play Services|
Wear OS brings over Android Wear 2.0 improvements including:
- improved fonts
- pure black background on native menus (better battery life). Apps may choose to have a non-black background.
- vibration customization (normal, long, double)
- connection status display, with up/down activity arrows on whichever connection method is being used (LTE, WiFi, or Bluetooth/BLE).
- auto-size text, based on how much text is in the notification
- better rejection of accidental side-swipe and long-press
Wear OS allows easy toggling of the watch Bluetooth and Bluetooth LE (BLE). This means the watch doesn’t search for the phone over BLE, saving battery. This could be useful for users that leave their phone deliberately behind for jogs and the like. Most users won’t use this, but for geeky/power users that like to experiment with Wear OS wireless, it’s really nice to have manual Bluetooth enable/disable.
Find my Phone–over LTE
If you have a large home or office where you could be out of Bluetooth LE range, with Wear OS you can use Find My Phone to make your phone ring over LTE, Wifi, and Bluetooth.
By tapping on an email notification in Wear OS, you get the first several lines of the email. You can also reply to emails from the smartwatch.
Assisted by GPS / LTE based Wear OS location, the standalone Uber app is one of a growing fleet of standalone Wear OS apps that work great from the watch, even if you forgot your phone or the battery died. I believe this Uber standalone app will save lives and improve safety for those with a dead phone who otherwise might be stranded and have to find a riskier way home–instead they can use Uber from their Wear OS watch.
Wear OS security
- auto-lock: Wear OS locks within a second or so of the watch being removed from my wrist.
- Email: you can read and reply to email someone sends you.
- Google Keep: Can read all notes
- Hangouts/Skype: can read prior messages and calls
WiFi WPA-EAP (RADIUS)
WiFi WPA-EAP WAPs as used in corporate networks (or excellent home networks) require the Wi-Fi Manager appfour app. Wear OS won’t connect to WAP-EAP without a third-party app.
Consider the security implications of entering your 802.1x password into a third-party app! Particularly if your institution has a single signon (SSO), you could be making a major security risk–don’t enter such a password into a third-party app.
Android Device Policy, a BYoD-focused app, does not allow your Wear OS smartwatch to use your work email as the primary account if your administrator requires encryption. Wear OS does not use device encryption.
Workaround: Use a personal gmail.com address as the primary device address.
Wear OS allows PIN, Password, or Swipe pattern. Wear OS for better security should force you to unlock your phone with password and then reauthorize the watch after say 3 or 5 failed attempts to unlock watch. Right now after 3 failed attempts with Wear OS, you get locked out for 1 minute. This is not secure enough in my opinion, and should be at least made an option.
