Review on J&D Armband: Compatible for Samsung Galaxy S10 Plus/S10+/S10 5G/S10 📱 Lite/M12/Quantum 2 – Sports Running Armband with Key Holder & Earphone Connection by Calvin Reynolds

I like everything so far. I took it on two runs of about 5 miles each. It is very comfortable and easily adjustable. I have a Galaxy S8+ with a fairly large case and it barely fits in. It's difficult to use the phone in a case while it's in a bracelet. It fits perfectly without a case. What doesn't bother me is that with the case the top of the headband covers the sensor at the top of the phone so it always assumes you're talking about it so the screen indicators don't light up,
