Have had my Galaxy active 2 for just over a year and one morning wake up to the screen being totally non-functional. The side buttons work. I performed at least four factory resets. The screen is in totally flawless condition there's not even a scratch on it. I contacted the local certified Samsung repair center and was told that the part to repair it cost almost as much as the watch itself. So am I basically stuck with no watch now?
I am having the exact same issue you mention. My Active2 stopped working after last update.
I understand Samsung wants to charge to repair this issue that is caused by their own software update.
Has anyone checked the cost of this repair by Samsung?
