According to a new post in Samsung’s Members app in Germany, upcoming 2021 Galaxy phones won’t be compatible with some older Galaxy Gear warbles released between 2013-2014. The affected devices are as follows: Samsung Galaxy Gear, Gear 2, Gear 2 Neo, Gear S and Gear Fit. Users of these warbles will be informed via notification from the Galaxy Wearable app if their device will no longer be supported.
For the time being it seems the Gear S2 and Gear S3 won’t be affected as they are not explicitly mentioned. Samsung also says that all current Samsung 2020 smartphone models will still be compatible with the entire Gear lineup.
