iPhone7 Bluetooth issue in the car

My brand new Iphone7 seems to have bluetooth problems in my car. Everything works but the sound drops sometimes (often) when I listen to music. I didnt have this issue wiyh my 6s and IOS10. I tried to reset everything but the problem persists. The iPhone is recognized by the radio inmy Toyota, but the sound drops just as it was a radio in a tunnel.

iPhone 7, iOS 10

I provided this to the techs weeks ago, but it seems like there was no headway. So here are the results of my trials for everyone to read:


I work in an environment where I have access to soundproof rooms. The walls are steel with padding and are about 6" thick (solid). These are "dead spots" for wireless in my building, which I surveyed and had to plan around because of the walls. I also work with deploying a lot of iOS devices, so most of my colleagues have an iPhone.


Testing environment:

I tested the area with an OptiView XG using AirMagnet Spectrum XT software. This device and software is used to measure the amount of Radio Frequency (RF) radiation in a given area to troubleshoot issues with wireless, and to help design wireless networks for large corporations. This helped me to ensure that there were no stray 2.4GHz interferers while testing, meaning that the only devices emitting 2.4GHz band RF were the "Devices" listed below (Beats Pill, Plantronics Backbeats, Braven BRV-1) and the phones.


Additionally, I tested the cars listed below in several environments with and without interferers nearby. These were less controlled, however mirrored the exact same results.


Stuttering/Skipping:

To show an example of the skipping sound that I am referring to, please take a look at this video: https://www.youtube.com/watch?v=kGHFDRVA958


Bluetooth devices tested:

  • Cars: 2013 Ford Focus, 2011 Toyota Venza, 2007 BMW 335i, 2006 VW Jetta
  • Devices: Beats Pill, Plantronics Backbeats, Braven BRV-1


iPhones tested:

  • iPhone 6s - No problems
  • iPhone 6s Plus - No problems
  • iPhone 7 Plus (AT&T, A1784) - Stuttering
  • iPhone 7 Plus (AT&T, A1784) - Stuttering
  • iPhone 7 Plus (AT&T, A1784) - Stuttering
  • iPhone 7 Plus (T-Mobile, A1784) - Stuttering
  • iPhone 7 Plus (Sprint, A1661) - No problems
  • iPhone 7 (Verizon, A1660) - No problems
  • iPhone 7 Plus (Verizon, A1661) - No problems
  • iPhone 7 Plus (Verizon, A1661) - No problems
  • There were two other GSM iPhone 7 Pluses that I trialed, but I don't have the model numbers in front of me to list to provide exact details. Both had issues.


As you can see, the issues are localized to the GSM models using the new Intel modems. This further solidifies the belief that there is an existing hardware issue and not a problem with software, interference, or other manufacturer's devices. I'm not sure what else I can do to troubleshoot with the Apple reps, but after spending upwards of $5000 with Apple in 2016, I can't help but to feel neglected.

I reported that the Verizon Iphone 7+ 256GB does not have skipping issues. My girlfriend and I have the same phones except she is on Verizon and I'm on AT&T. After 1 hour of use in my Lexus her phone did not "skip" once. However, my phone currently with ios b5 still has the issue. Whether its the Quailcomm modem in the Verizon phone or a specific issue with AT&T service I'm still not sure but I'm so fed up.

Big Brother keeps deleting my posts, so I'll be as vague as possible.

I got my AT&T 7 Plus on day 1. I've had music stuttering problems since week 1. A couple weeks ago it seemed to have been fixed. I had one small (we're talking milliseconds) staticky dropout in about 10 hours of streaming. However, since yesterday, it has been back to drops/stutters/speeding up the music. Either Apple broke it again, or maybe I had 10 lucky hours. Either way, we're almost 3 months in, and someone at Apple needs to rectify this.

The Bluetooth problems only exist in my 2014 Ford Escape. My Bose QC30 earbuds have had no Bluetooth issues in over 50 hours of use. Both the Bose QC30's and iPhone 7 Plus use Bluetooth 4.2. Ford Escape - who knows what version...4.0?

I have also been having major bluetooth stuttering issues since getting my iPhone 7 Plus (128GB AT&T locked). It happens a lot on my commute to work and actually happens in the same locations. It's pretty clear there are some hardware issues going on here and it would be nice if Apple acknowledged the issue. If you are going to remove the headphone jack and make a bold statement about wireless being the future, you should probably make sure bluetooth actually works.
