I had my motherboard replaced on my phone too, it did not solve the problem.   I made sure I checked my bluetooth before i left the store. What we found was, at first my bluetooth worked. But once I downloaded fitbit and tried to connect this didn't work. My phone would then not connect to anything else via bluetooth. We then removed the fibit app and then bluetooth suddenly worked again for everything else. This suggests there may be something wrong with the fitbit app, so I am going to contact them directly regarding this.  ... View more

Hi, OP here.   I actually took my phone to a Samsung centre last weekend but was waiting for it to be resolved before I posted Their initial diagnostics showed nothing wrong. It then went to the techs in back and I left it there for a few hours. At the end of the day they told me it's something wrong with the mainboard. I'm not very tech savvy so I'm a bit confused how the software update can affect the hardware but we'll see. They couldn't order it in until the Tuesday (this was at the weekend) and I couldn't get there during the week, so we agreed they will order the part and I will bring it in this coming weekend, and they can fix it on the day. However I called to check it was in on Thursday and I was told they don't have it, and they don't order parts until the phone is physically there to be repaired. This means I will be taking it in this weekend and not having a phone for a week, not very happy as they told me the incorrect info in store. I might as well have left it there last weekend, so I am feeling quite frustrated with them.   Once this gets gets resolved I'll confirm whether it's fixed the issue.  ... View more
