Review on 🏋️ Universal Exercise Armband, Lommishop Sports Arm Band for iPhone 12/12 Pro/12 Mini/11/XR/8, Galaxy S10/S9, Fit 4”-6” Smartphone, Cell Phone Holder for Running Gym Workout, Medium Arm Size 9"-13 by Jeremy Black

Perfect for my use, doesn't slide off my Galaxy J7 Crown phone; leaves enough room for the camera to work perfectly with the phone mount attached, the speaker works great, all the functions of the phone work. Not only does it work on the bike, I use it to clip it to my, er, bra and talk hands-free, and when I'm riding I never miss a beat, let me be hands-free. So sorry, so sad guys. I know this doesn't apply to you :) The headphones don't help me, they always turn off at the most inconvenient moment, interrupting the most important phone calls. It's perfect for all kinds of use together with the bike, try it, great price! :)
