I am under the impression that the Bluetooth transmission power of the FP6 is relatively low compared to my old iPhone SE. For example, I used to place my phone on the living room desk. I could easily walk through the whole falt listing to music via Bluetooth without any obstructions in listening quality. This is no longer possible with the FP6. The connection usually gets weak when I go to the room next door. Is there anything I can do about it? Is that at all a hardware problem or could it also be an issue with the os ( /e/OS in this case) ?
