I have an Iphone and was planning on using an Android so I guess both of us are out of luck. Unfortunately support is not willing to give more information but I also suspect damage across the line.
My case is a little bit trickier as I purchased 2 units with the help of a US friend and have them shipped to EU so I’m not covered by warranty and Anker seems very unwilling to admit the problem.
Overall a huge disappointment this experience and this is a product I wouldn’t recommend so far. When worked, it sounded awesome but paying 250USD for a bricked BT speaker is way too much
