Gear S2 non-classic version(the cheaper one) has a very serious strap problem. The strap glue is weak and it comes off easily from its latching mechanism hinge. Samsung doesn’t acknowledge it and will not replace your band under warranty.
There are many users with the same problem. Someone has to launch a class action suit against them. I’ve noticed no Bluetooth connection sustainability issues.Watched the video and am wondering if you’re on crack. The selector is going the same direction as the bezel rotation, as shown in that video.
