Samsung Pay with Gear S3 Currently Doesn’t Work on Pixel Phones
A major selling point of the new Gear S3 smartwatch from Samsung is the ability to use Samsung Pay directly on your wrist. This includes both NFC and MST capabilities, so even if the pay terminal hasn’t been upgraded with a contactless payment option, then you can still use it on the magnetic stripe part.
This has been known since launch, but then a couple of weeks ago Samsung said that it would also work on non-Samsung smartphones.
This makes sense because the NFC and MST features are built directly into the smartwatch, but many thought Samsung would restrict Samsung Pay to Samsung devices anyway. This confirmation via Twitter has since been deleted, but many Android publications started to cite it with headlines claiming Samsung Pay on the Gear S3 would work on any Android 4.4+ device. Sadly, this is not the case and many people are just finding out about it now.
Granted, it does work with some Android devices running Android 4.4 KitKat and higher, just not all of them. While there are likely to be some other devices are are incompatible with Samsung Pay on the Gear S3, the big one that has been uncovered is the Pixel and Pixel XL. Samsung has confirmed the feature will not work with either of these two smartphones, but doesn’t go into detail to tell us why.
It doesn’t seem to be an issue with Android 7.0 Nougat, as Samsung Pay on the Gear S3 has been shown to work on the LG V20. Samsung does say they are “constantly working to expand Samsung Pay to new devices,” and to “stay tuned,” but doesn’t give any details about when or if this will happen for the Pixel phones. For those looking to buy a Gear S3, you can refer to this list and see which devices are guaranteed to work with the Gear S3.
Edit: XDA Recognized Contributor deadman96385, along with some comments from XDA readers, have pointed out that it seems to be an issue with Android 7.1 Nougat as a whole. Changing the sdkVer field to 24 (which is Android 7.0) gives you a download link, but it still will not install. Thanks to everyone sent this in.Source: @SamsungPay
