Google's fitness app is no longer marked as 'incompatible' with phones like the Galaxy S6 and Galaxy Note 4, as the long-running heart rate sensor bug appears to be fixed.

If you've tried to use a Samsung phone running Android 5.0 Lollipop with Google Fit, you'll likely be aware of the long-running compatibility problems between the two. Samsung owners on Android 5.0 found that using Fit's activity detection feature caused phones' heart rate sensors to become active all the time — meaning they'd light up when touched, even when the screen was off, which wouldn't do devices' battery life any favors. In recent weeks, Google took the unusual step of marking the app as "incompatible" with most popular Samsung phones through the Play Store, in order to limit the effects of the glitch. The bug was particularly irksome for Android Wear owners with Samsung phones given the deep integration between the fitness app and Google's wearable platform.

After six months, Google Fit is no longer 'incompatible' with some of Android's biggest handsets.

Now, with the arrival of a big new update for Google Fit comes an apparent solution to this more than six-month-old bug. The app is no longer marked as incompatible with Samsung phones like the Galaxy S6, Galaxy S6 edge and Galaxy Note 4 on the Play Store, and upon installing it we've yet to see any trace of the heart rate sensor issue.

It's worth remembering that we're still in the midsts of a staged rollout, so there's no guarantee you'll get the latest version if you download Fit from the Play Store in the usual way. So Samsung owners may want to hold off until the new version 1.52 pushes out to everyone. But after half a year of this Google app being broken on some of Android's most prominent phones, what's another week or two?
