Long story, lol.
I started reading this forum even before I got my Note5, as I knew it would come in handy, and I read the S5 forum a lot while I had it. I got my Note 5 two weeks ago last Saturday. I used my bluetooth earpiece a couple times and had no problem, so I mostly disregarded this thread. Couple days after that it started cutting in and out, and I thought it was because I was wearing a beanie over my earpiece. A day after that it started disconnecting and reconnecting constantly while the phone was in my back pocket, and simply wouldn't stay connected, so I came and read this thread. I tried every trick and tip I knew and then everything listed here, minus the factory reset, to no avail. Then I went back to the AT&T store, filled my guy in, and told him about this thread. It failed to work for him too, backing up my story. He had me call Samsung to document everything, and of course they told me to do a factory reset before calling them back the next day. Factory reset did not work, so I called Samsung back, but all they offered was to have me ship it to them for repair and they would ship it back. I cannot be without a phone, my husband is on an organ transplant list. I politely declined, but made sure Samsung documented my account with everything. I went back to my AT&T store, but my guy had the day off, and I preferred to wait for him, so I went home and spent the rest of the day experimenting with it.
Here's what I found. WiFi was definitely a factor, any time my phone was within wifi range, it disconnected or had the signal break up. Even with the wifi on the phone turned off. I wear my earpiece on my left ear, and I could block the signal simply by moving the phone to the right side of my head, putting it in my pocket or simply waving my hand in front of the phone. The only way the bluetooth would stay connected was to hold it right in front of my face. But if I was driving down a road, too fast for any wifi signal, it would stay connected with no problem, even in my pocked or behind the seat. But what good is that if someone wants to save data and say, stream Pandora, on wifi using a bluetooth earpiece? Nada.
My guy at AT&T was great, since I was still within the 14 days, he called it a factory defect out of the box, and got me a new one. We activated the new phone literally on the 14th day. I'm happy to say as of right now, the new phone is working fine!! I'm now past 14 days, so if something goes wrong with the replacement, the repair will be my only option, since it's still under warranty obviously. Fingers crossed that this is a normal phone, as I totally love the Note 5!!
Long story I know, but I wanted to be as clear as possible with the problems I had. It clearly seems to me to be a physical bluetooth/radio defect. I'm worried only because someone way back in this thread is on her 3rd phone! Fingers crossed.
