My V10 does the exact same thing. I just got off the phone with my carrier obtaining my second warranty replacement. This didnt start until after the 6.0 software update. I have done a factory data reset after going through all the other steps (clearing cache, unpair all bluetooth devices, pair again one at a time and test to see if its a specific device, and so on) but nothing has an impact on the issue. After 8-10 minutes, bluetooth just toggles off, my headset (curiously I am using the newest LG Tone Platinum and the same thing happened when using my previous Tone Active...) or car or speaker just... drops off. I can turn bluetooth back on manually and reconnect but thats all. I did notice that it seems to happen over a short bit of time. The audio quality of bluetooth connections has seemed to deteriorate over the last two weeks or so, getting choppy or losing range. After that period of time it goes full into this mode of turning off ever 10 min. This is clearly a software or driver issue as everything works fine for a while and then goes bad in a predictable pattern. The bluetooth module in the device is the same as that in the G5 (my work phone) which does not have the same problem. While waiting for a replacement I will use my work phone more and not have this issue. It would be great if LG was a bit more in touch with customers and actually cared to send out some kind of expedited patch to those of us who have paid decent money for the device. LG is about as easy to reach as the top of a pyramid scheme, so I am not about to ship it off and be without a device for weeks. Im hoping that the replacement handset I get is newer than the one I have now. I believe (this is not a certainty, but close) that the firmware that ships on newer versions of the phone is updated as compared to the one I bought in November and on the replacement. So if I am lucky I will get a newer one and perhaps this will not recur.
