In September 2016, I purchased and iPhone 7 plus. Originally, I had purchased an iPhone 7 as the iPhone 7 plus was out of stock. I have iPhone 7 launch story, one that taught me that I would not waste any more time pre ordering an iPhone. That, however, is not the reason I write this today. My reasons for writing today are related to the Bluetooth “audio stutter” issue I have experienced since day one of ownership.
I own a 2012 Ford Fusion that is equipped with a basic Sync system. All my prior iPhones have connected and played audio via Bluetooth since owning the car. The only problem I have experienced previously was sometimes the Ford Sync refuse to pair to the phone via Bluetooth. The fix required turning off Bluetooth on the iPhone and turning it back on. I took part in the iOS 10 Public Beta test over this past summer. During that time, I felt like my iPhone 6s performed the best it ever had in regards to Bluetooth.
Since owning the iPhone 7 plus the experience has been quite the opposite. While listening to my music or favorite podcast via the Ford Sync the audio would randomly stutter or more appropriately, it will garble for a few seconds and then resume to normal. The issue happens quite frequently, which makes listening to audio painful. This has been on ongoing issue since September and has yet to be resolved via an iOS 10 update, restoring my iPhone to new, updating my Ford Sync system, resetting the Ford Sync system and so on.
On Saturday November 19, 2016 I made an appointment to visit the local Apple Store. Through the troubleshooting with the Genius I was asked to “Reset Network Settings”. I was also asked to test my Ford Sync system with another device. In this case I used my wife’s iPhone 7. I completed both tasks, my iPhone 7 plus still experienced the audio stutter problem and my wife’s iPhone 7 did not have the audio stutter problems.
On Tuesday November 22, 2016 I again visited my local Apple Store Genius and it was determined at that time to replace my iPhone 7 plus. After setting the device up as new (running the latest iOS software) the phone still experienced the same audio stuttering.
In my search of the Internet, I came across this Apple’s Committees Discussion Board thread https://discussions.apple.com/message/31146947?ac_cid=tw123456#31146947. Based on the 27 pages of responses I am not alone in my struggle. In this thread, I discovered numerous vehicle types of various years all the way up to 2017 were having issues. Many of the comments noted taking the same steps that I have and the problem persists.
What I have learned from this thread is that I can prevent the audio stuttering by turning off LTE Data. This is done by going into Settings > Cellular > Cellular Data Options > Enable LTE and selecting off. What I also learned was that for the most part those with the audio stuttering issue are primarily to those who own an iPhone 7 plus on AT&T.
This was profound to me, due to the fact that Apple produced Model A1784 as a GSM only model used in the United States on AT&T. This model of phone is not capable of running on Verizon or Sprint as it does not have the CDMA chipset. In fact Model A1784 sports the new Intel cellular chipset, not the previous Qualcomm chipset found in previous generations of iPhones and Model’s A1660 (iPhone 7) and A1661 (iPhone 7 plus). http://www.apple.com/iphone/LTE/
Is it faulty Hardware?
If the new Intel cellular chipset is to blame for this audio stuttering issue, then I believe Apple has a serious issue on its hands. I have a limited data set to prove this as the issue, but given the Apple Community Discussion thread above and my own personal experience, taking LTE out of the equation solves the issue. It could be something faulty in the chip I don’t know. As of this writing, I am in the process of purchasing a SIM free Model A1661 to test my theory.
Is it iOS 10?
Software could always be an issue. To date no update has resolved the issue. Apple stated in the release notes that iOS 10.2 fixed Bluetooth issues, but the fixe failed to correct my audio stuttering issue. Given the Apple Community Discussion thread above had people noting the same issues on Verizon I am wondering if Apple has yet to identify the issue in iOS 10, but if that were true I believe that I would have seen talk about this issue cropping up with the iPhone 6s or later. However, I believe this is not true given many people in the thread have returned their iPhone 7 plus and downgraded back to the 6s plus and report no problems after doing so. One other note is that I have yet to see anyone commenting from any other carrier outside of AT&T and Verizon.
Hardware on iPhones has had some issues in the news lately, primarily related to the battery shutdown (https://www.apple.com/support/iphone6s-unexpectedshutdown/) and touch disease (https://www.apple.com/support/iphone6plus-multitouch/). This leads me to conclude that Apple is not immune to faulty equipment.
Is it AT&T?
This seems to be the most likely scenario. One common item to both iPhone models I have received is that the SIM card has never changed. I also have not noticed a Carrier Settings update on my iPhone in the whole time I have owned it. Could the iPhone 7 plus models shipped towards the beginning of launch have a faulty SIM? I am not sure, but a run to my local AT&T Store may be in order test my theory.
My issues are certainly not life or death, more along the line of first world problems. I am impressed with the iPhone 7 plus. It has nice battery life; it takes very good photos and is very fast. What I have a problem with is Apple not addressing the issue. I have a case started with a Senior Apple Tech Advisor and until I alerted him to the above thread he refused to acknowledge that anyone was having an issue. I am, as of Friday December 23, 2016 awaiting a call back. Given the Holiday’s here in the States my expectations are low that this will happen in the near term. If software, a new SIM free Model or new SIM card do not solve my problem I am left with a few options:
- Continue to leave LTE off. Okay that’s an option, but certainly not the ideal option.
- Hope that Apple or AT&T provide a software fix?
- Sell my iPhone 7 plus and downgrade back to a 6s or move to the Android Platform.
If it is a hardware issue, I hope that Apple has the “courage” to own up to its issues as Samsung did with the Note 7 and take the phone off the market. Yes this may be a bit extreme and not an apples to apples (pardon the pun) comparison, but a nearly equally misstep in my humble opinion.
If you are experiencing the above issue, please let me know.
