The Wear OS 5.1 update for Pixel Watch users enhances app visibility by adding a small circular app icon to the top of each tile. This update, part of the March feature drop and based on Android 15, was initially rolled out for Bluetooth and Wi-Fi-enabled Pixel Watches and later made available for LTE-capable devices, including Pixel Watch, Pixel Watch 2, and Pixel Watch 3. It includes features like the FDA-approved Loss of Pulse safety function, menstrual cycle tracking, and improved step tracking. However, the update has caused issues such as delayed notifications and battery performance problems, prompting user frustrations and temporary solutions like restarting or factory resetting watches. Google has acknowledged these problems affecting a small subset of users.
