I have used Samsung phones since I have hear about Android, I never bought another brand and I'm happy with your products. But not for my Watch, I have a Galaxy S3 Frontier. Since I bought this watch I have many unfortuned experiencies. First it was not supported to work with my mobile, but in Germany it was. I asked Samsung and a year after they release an update to their software to extend support to my Samsung phone. Ok, every think was ok. But I´ve decide to change my phone OS. Now I'm using Lineage and it works very well, but Samsung another time have blocked my watch. Now I'm receiving an ridiculous message "your phone was unautorized modificated". I will continuing to search for a solution to use my Watch.
