Agreed!

I can't take full credit for the information, as it has also been reported here:

I’m here because I reproduced and documented a breakdown of a core security feature.

I have not seen a breakdown in any core security feature posted here, so not sure what you are referring to. If you do have a documented security concern, then definitely report that here:

It is true that you should be able to continue even with an app that has been deleted, but that has never been the case ever since Safety Check was launched 2 years ago. I would recommend filing a bug report as the same thing happens to every user who has deleted any of the apps that it is checking for. It is repeatable as you can have it run successfully, then delete the Fitness app and it will fail. Redownloading the app will allow it to continue again. What is difficult to determine is which app is causing it to fail and is not always the one listed. It could be Home, Fitness, Health, or even one of the other apps.

Get whichever iPhone here fixed, or get it replaced, or get another number or another phone — get whatever is blocking you from calling and contacting support fixed, or at least worked around.

Once you have that sorted, if overt iOS issues persist, perform a factory reset and re-install. By overt, I mean demonstrable functional problems with the iPhone. Not analytics chatter. There is always analytics chatter. And by factory reset, I mean a factory reset and not a Safety Check.

Analytics and telemetry are useful to Apple, and to app developers debugging their own apps. More generally, not so much. Apple has roughly two billion devices in use, so they have a pretty good selection of data to scan for oddities, and has the the servers and the staff necessary to create and maintain whatever rules and ML implementations are deemed necessary. And developer can pull crash data and related details associated with their respective apps. I’m sure some folks are manually ingesting data from whatever devices are available to them locally, and some then comparing that data using locally-created rules and local ML implementations, too.

In a different phrasing, reading analytics is like for looking for needles in haystacks, with ever-increasing numbers of haystacks, when not sure of what the needles look like, or even if there are needles.

Is it possible you’ll find something? Sure. I’ve certainly found various bugs in the local configuration, and in apps, a d occasionally what look like bugs in Apple code.

Finding debris from exploits is rather more rare. And for that investigation there usually needs to be some corroborating misbehavior or personal risks, as well. A few dumps of benign log chatter is not that. (And some of the exploits are taking the simple expedient of deleting the local logs.)

Why go for a reset first? Resetting clears corruptions, buggy upgrades, and buggy apps. Describing how to reset is far easier and more efficient than describing the details of identifying and fixing issues; bugs, corruptions, exploits, or otherwise.

If the problems persist after the reset, it’s then potentially flaky apps or quite possibly flaky hardware.

If it’s not flaky hardware, then you may well have personal risks and a well-funded adversary, which puts your request far outside what can assistance can be offered in a forum.

On the path you’re currently on, you’ll want to learn more about forensics collection and analysis. That’s not going to happen in a forum, and certainly not one screenshot or one analytics section at a time. Apropos of the current AI marketing efforts as applied to information security and forensics, using GPTs for analysis here will be at the intersection of helpful and wrong, though custom-built MLs can potentially find some surprises.

Guess what?

It failed.

Emergency Reset couldn’t even stop sharing with Fitness and Home.

If logs are “useless,” why does Apple collect them? Why do devs want them? Why do they trigger remote diagnostics?

I am a developer with several apps in the App Store and do use logs in my programming. I also get crash reports from users to review those logs. The information I choose to log is only relevant to me and is useless to the user. I choose what I want the log to say and when to log that information. Many times I will choose to log info when I expect something to fail as that is exactly how you program for error handling to prevent a crash that results in the app being closed. Other times I will print a log that just confirms a part of the program has executed and what I print will mean nothing to the user. I could log "Intrusion Alert!" and nobody knows what I am talking about other than me. I collect them for my purpose and Apple collects them for their purpose. It really is that simple!

You’re not protecting users here. You’re protecting a script.

There is no script. You have not even posted a problem with your iPhone. The truth is looking through the analytic logs and googling what you see there or trying to figure out what they mean is going to be a complete failure. I even suggest you google "StreamingUnzipService" like you have already posted about. You will see reddit posts filled with claims that says it means your phone is hacked. I have also seen Gemini AI results in the Google search regurgitate this false claim since Google partners with Reddit to train their AI models.

We have seen this all too often here and simply will not go down any rabbit hole with the user. The recommendation is to quit looking through the Analytic Logs as they will serve no purpose, other than to feed the panic frenzy seen across all Social Media platforms. Concentrate on the problems you are having with your device.

Without knowing more about the error message you received or whether you were even sharing anything to start with, it's impossible for anyone here to comment on why that happened.

So here’s what I’m asking now: is this finally considered “overt enough” to acknowledge something’s wrong?

I don't think anyone ever said that there was nothing wrong with your phone. What was said is that the information you've provided does not indicate anything wrong.

Or should I go ahead and reset again, lose more ground, and let this pattern of gaslighting continue?

People giving you an answer you don't like is not "gaslighting." What you seem unable to consider is that your original premise could be incorrect.

Because here’s the truth: I’ve seen other people in this forum ask real questions, report similar patterns — and they got talked down to, pushed off, or ignored. Maybe they didn’t have the logs or language I have, but they weren’t wrong.

No, again, when people come here posting that they have been hacked and that their analytics are "proof", people will explain the actual facts to them. But, like you're doing now, they don't want to believe that whatever is wrong is probably far more pedestrian than hacking.

You’re not protecting users here. You’re protecting a script.

We don't have a "script." We have knowledge and experience.

If logs are “useless,” why does Apple collect them? Why do devs want them? Why do they trigger remote diagnostics?

No one said they were useless. It was explained that they are useless for the end user who's trying to prove their phone was hacked. Analytics have lots of uses for engineers and developers.

I don't recall ever seeing documentation that they trigger remote diagnostics.

Thanks for the reply. I understand that logs like installd and StreamingUnzipService exist as part of normal system behavior. My post wasn’t meant to suggest otherwise…

Once you’ve factory reset and re-installed iOS, if the problems persist, then contact Apple Support and get the hardware looked at. Or get the battery replaced. Or if whichever iPhone is flaky and can’t run iOS 18 or whatever threshold you decide, then get it replaced with a newer (used, refurb) or new iPhone, or some other phone that meets your needs.

I didn't say you were seeking upvotes or attention, what I was referring to is users who have been looking through logs and come across processes like StreamingUnzipService and do a Google search. This will bring up those fake posts from Social Media claiming that the device is hacked. Now with Gemini AI being used by Google and partnering with sites like Reddit, you will even see an AI response make that claim. Garbage in = Garbage out.

Your device is far from idle even when there are no apps running and in Lockdown Mode, with processes continuing to run and logs being generated. Lockdown Mode does not prevent all network traffic and even when an internet connection is not possible the processes, like nsurlsessiond will still run, whether they fail or not. Every background process has a priority flag attached to it and when your device is idle is exactly when the low priority processes are supposed to run.

Communication with Apple servers also occurs frequently. The phone continues to scan WiFi networks in your area and checks for Bluetooth devices as well. Even with those options turned off, the processes will still run and may even log an Exception with a Trap as seen in your post as a Sigtrap to report the state of the device registers and the state of every processor. Find My is constantly in communication, updating your location and checking for devices in range to update their location if needed.

As stated already you can certainly set your device to automatically share your logs. You will not get any feedback from them as the logs are completely anonymous without containing any personal identifier information. Apple does not know whose logs they are and they are used by them internally for improvements in the OS.

Sorry, but there is no concern seen there with any of the reported logs or even by their frequency. Your phone will supply a never ending list of logs with old ones deleted after new ones are added. What has not been reported is anything that is wrong with your device or an issue that you are experiencing with it. The logs are not an issue.

StreamingUnzipService is a standard process on iOS and you should see logs with that name. Years ago there were people that were spreading lies on Social Media that it meant your phone was being tapped by Law Enforcement. It was total nonsense, but of course all the poster wanted was getting upvotes and sharing their claim for notoriety. Others who checked their device found the same thing and were convinced their device was hacked.

Installd is the centerpiece of any UNIX type operating system to make sure all necessary processes are running. If one gets quit, it is the installd daemon that is responsible for making sure it starts back up again.

Apple is not here in this Support Forum. You can send feedback to Apple here:

Contact Apple Support - Apple Support

Are you experiencing any problems? Exceptions, Faults, and Failures are totally normal in the Analytic Logs and are expected. In some cases they are used to document that a normal branch in coding occurred and at other times Engineers use them to confirm that the expected condition has been met.

You can set your device to automatically share Analytic Logs to Apple.

Share analytics, diagnostics, and usage information with Apple - Apple Support

Other times they are only necessary when an Engineer has requested them after opening a Support Ticket with Apple Support on a specific issue you are having with your device. Looking for an issue in the Analytic Logs by any user is just going to be a fruitless effort. You will find nothing of value there.
