Review on JEMACHE Galaxy S21/S20/S10/S9/S8 Armband – Ultimate Phone Arm Band for Samsung Galaxy S8/S9/S10/S20/S21 5G Compatible with Otterbox Defender and Lifeproof Case (Black) by Carrie Porter

This is said to be the version that works with Samsung Galaxy S9 with Otterbox case. It fits well, but there are some issues with side button presses and capturing finger gestures and touch controls on the display. That's because of the cheap plastic coating and the fact that most Otterbox case owners will also have a tempered glass screen protector. Since this plastic cover doesn't interact well with the tempered glass screen protector and pressing the side buttons is a bit annoying, I gave it 3 stars out of 5 because it still acts as a phone holder and wraps around your arm when you run a workout. But at the moment it leaves a lot to be desired in the normal functionality of the phone itself, being in this holder.
