Hi, I unpacked brand new pair of Air Pro 4s and it doesn't work right from the box.
Yes, I unwrapped both stickers and reattached buds to the case. At first right bud was working, connected immediately. The left one doesn't show any signs of life, so I thought it's battery drained. Case was full of charge, but to be sure connected to charger anyway.
Earfun's android app doesn't help so I decided to reset buds. Unpaired the right one, put both buds in case, reopened lid and pressed pair button about 8 seconds as instructed. The right one started flash rapidly, the left one as usual no lights at all. After that I can't connect the right bud either! I tried with many Samsung and Oneplus devices, from app, from bluetooth list no luck and doesn't show that fast pairing pop-up animation either.
Now then I open the lid 3 second constant light on both(!) sides, after the right bud start flashing like in pairing mod. So case hardware wise can detect left bud then opening lid (first 3 seconds) but not then put it back in case like right bud. Now both buds undetectable by bluetooth and right one flashing in case endlessly. What should I do?
