Galaxy Watch 4 gets April 2023 security patch with build GWD6 [Big Update]

Samsung Galaxy Watch 4 Bluetooth and Watch 4 Classic LTE are now receiving the latest April 2023 security patch featuring Samsung Health updates. This takes the firmware of Galaxy Watch to the latest offering from Google’s Wear OS 3.5.

The latest April 2023 update for the Samsung Watch 4 updated the Samsung Health app. While the patch notes do not say much other than improvements to the system, the OTA comes in a huge package weighing 300 MB in size.

This is a big update for just a security patch. There may be many under-the-hood changes and improvements to the system.

The previous Watch 4 update enabled some One UI 5.1 features. The OTA came with new Camera Controller Zoom features with pinch-to-zoom capabilities, self-diagnosis tools, and some One UI 5.1 feature hints.

The February 2023 update also offered fix for a critical bug where raise-to-wake won’t work correctly. This bug was introduced in the previous update GWA3 with the same changelog.

The GWD6 is a major update weighing about 300 MB in size. It features the latest Android security patches from Google. The Watch 4 series will receive February 2023 security patch later this month.
