New rumors about Samsung's Galaxy Watch 4 tell us that a release date is imminent, but there is also bad news about one of its coolest features.

South Korean news site Money Today reported, citing industry sources, that Samsung claims the Galaxy Watch 4 will not include a blood glucose monitor. However, both the Galaxy Watch 4 and Galaxy Watch Active 4 are expected to launch in the next two to three months.

A blood glucose tracker is an exciting feature that could be a useful health check, especially for diabetics who need to check their glucose levels regularly. In theory, the Galaxy Watch provides these users with the results they need without the need for an external blood draw, saving time and discomfort.

This feature is said to be coming to the Apple Watch 7, but we have heard that it may be skipped this generation. However, if Apple can implement blood glucose monitoring, the Apple Watch 7 will have a significant advantage over its rivals.

The report repeats the claim that Samsung will run the Galaxy Watch 4 on Google's WearOS rather than its own Tizen OS. The current Wear OS is more basic than Tizen, suggesting that if Samsung wants to keep the advanced features it has already established, it will use a heavily modified version. [This is because Wear OS is a well-supported Google product used by several smartwatch manufacturers. As a result, more apps may run on the Galaxy Watch.

The Money Today report also details that the new Galaxy Watch will come in two different versions, each with two size options. The Galaxy Watch 4 will be available in 42mm and 46mm faces, while the sports-focused Galaxy Watch Active 4 will be available in 40mm and 42mm.

Both watches are expected to launch in July or August, the same month as the Samsung Galaxy Z Fold 3 and Galaxy Z Flip 3. This would coincide with the launch of the Samsung Galaxy Watch 3 last year, while the last Active version, the Galaxy Watch Active 2, launched in September 2019.
