I got a new unlocked S8 this past week and bought the quick charger stand up version (not convertible) and the first time I used it I kept getting a blinking blue light. Found out it won't work if I use my magnetic phone mount, phone has that thin metal pad on it. SO I took it off, put phone (in Speck thin case) on charger and the phone registered the charge and showed it was charging when I went to bed 10:30pm). At about 4am when I got up to go to the bathroom the blue light was still on. So when I got up again for work at 7am, the blue light was on, and the phone was only showing battery at 80% or so and the phone was warm.
So what's going on? Is it a charger issue, I can exchange it. Or is there a phone issue maybe?
I was looking forward to using it, but if it's not reliable, I'll return and just plug in at night.
