It's really bad when you can't make a quality app for your products. I've spent 14 hours so far trying to connect my phone to 1 bulb. I have had to make adjustments to my router and everything else the website suggests I do. With my phone directly next to the light bulb and it says it can't find any Bluetooth devices. The app just won't connect no matter what, and when the app wants me to add a network and blocks me out of the app because the back button doesn't work. I have a Samsung Galaxy A51
