A week ago, my Samsung active2 watch started disconnecting about 30 times a day. I'd have to go on the wearable app to reconnect and a minute later, it'd disconnect again. To add to the frustration, yesterday the watch started vibrating 4/5 times in 10 second intervals. Then the screen turns black and I can't do anything on it! I have a huawei P20 - anyone have any suggestions to fix this please?
