Let me share my findings with More 1 (and 2). I tried both beginning in Jan when they were both first available. I too experienced the random BT disconnects. After extensive discussions with both Oticon and Samsung and a lot of tests I personally carried out - this is what happened.
Oticon admitted there was a problem and new firmware should address it. I had at least two firmware updates, the last being 1.004. I think it may have improved a little but still occurred. They may have released further firmware updates by now.
Samsung also admitted there were issues with their BT implementation. again a system update was promised to fix that. I had one system update while I had the More 1s but that did not make it any better. Further updates may or may not improve matters.
My own testing showed this… the new ASHA Bluetooth is lower power than previous versions. This means that when walking with the phone in my jeans pocket it would cut out especially when I turned my head to the left or right. Sometimes it would come back but not always or might take some time. BT signals do not travel through the body well and this would cause the problem depending on where your phone was in relation to the hearing aids. Following on from that, there were far less disconnects if I had the phone in my shirt pocket - nearer to the HAs. Furthermore, if I had the phone oriented in my pocket with the top of the phone uppermost there were less disconnects than if the top of the phone went in my pocket first - which I discovered was the usual way I placed it… I believe the BT antenna is at the top of the phone.
The fuss was too much for me… and promises from vendors or phonemakers may or may not happen in my experience… but perhaps they will fix it at some point. I had much better luck with Phonak.
I suggest you keep writing to Oticon tech support about this problem until they can assure it is fixed.
Hope that helps!
