The case looks nice, it's thin but made of strong material and big enough for my note 10+ with case. So far, so good. I have hearing aids that transmit data from my phone via Bluetooth, so the first thing I did was play a video, make sure the audio was working properly, then put the phone in my pocket and closed the flip. There were no changes in the sound from the phone. The bag could not block the Bluetooth signal. Bluetooth is RF, like all other signals sent or received by my phone, so I saw no reason to experiment any further. The bag just doesn't perform as expected, especially to enable RF communications when used as intended.
