Intermittently, when my OnePlus One is connected via Bluetooth to the cars built-in radio/bluetooth/speaker system, electronics fail on my dashboard.
When this problem occurs, I use the indicator and it doesn't blink on the dashboard at all - and it doesn't make the indicator noise whatsoever. It appears it does still work on the outside of the car though.
Sometimes I change the fan speed (1 through 6) and it does change (you can hear the fans change speed) - but the number displayed is fixed at OFF on the car centre console.
I've not had either of those problems for at least 6 months.
Today, I was driving and the indicator problem re-occurred, and a couple of seconds later, the car started alarming - the noisy alarm you get when you don't have your seatbelt plugged in (and are driving at more than10mph). I pulled over and the car continued to noisily alarm (even when stationary); presumably the car thought the seatbelt was not detected although there was nothing on the dashboard at all telling me this.
No error messages on the car dashboard. If anything, things disappear like the indicator (when indicating) vanishes from the dashboard when this problem occurs.
Car been inspected by Vauxhall in the last year regarding my problem and there are no error messages in the cars log.
It's only 15 plate (old Astra model) so should still be under the 3 year warranty (I believe it has 3 year warranty, bought pre-reg). They have previously reset the car's radio/bluetooth/speaker system but this hasn't fixed it.
I think their point is OnePlus One isn't a listed compatible Bluetooth mobile phone. So I guess the solution is for me to upgrade my phone, this just seems a really, really weird problem. It is all fixed by turning the ignition OFF and back On. But the problems occur after I start driving of course, so I have to park up....
Just to add, I have driven over a thousand miles with the phone connected and no problems, since the last indicator issue, so it really is very intermittent. And therefore hard to say it is definitively a phone/car problem - but how can a phone affect a whole cars electronics?!? Is this possible?
