Question:

Question: 4 partitions in my iphone 7

Hi all,


This is my first question to ask the forum and hopefully it wont be too much trouble to resolve this one.


Running an app called system status on my iphone 7 running iOS 11.1.1 to understand storage issues on a practically brand new phone, I found something that doesnt seem normal (granted normal is two partitions but this may have evolved with APFS)


In a nutshell - my iphone 7 has 4 partitions and the sizing of them doesnt sit well with me at all - nor does googling the mount points for the final two and returning predominantly JB references but im using 11.1.1 so this isnt a concern - unless it should be that is lol)


Partitions are as follows:


1. /DEV/DISK0S1S1 - total Storage 32GB (Used: 25.9GB. Free 6.1GB)

Mount point: /


2. /DEV/DISK0S1S2 - total Storage 32GB (Used: 25.9GB. Free 6.1GB)

Mount point: /private/var


3. /DEV/DISK0S1S3 - total Storage 10.5MB (Used: 0.5MB. Free 10MB)

Mount point: /private/var/wireless/baseband_data


4. DEVFS - total Storage 53.8kb (Used: 53.8kb. Free 0)

Mount point: /dev


I am used to seeing 1 and 2 - but never the same size like that - and its odd that they are identical. Any attempt at understanding what the third item is results in hcking forums and nothing else based on its mount point. And DEVFS is macOS and is almost ridiculous in its size of only 53.8kb.


Can someone help me understand if this is normal for ios11.1.1 on a iphone 7 or if something else is up. Lately I have been recieving notifications for apps - particularly messages - and they have vanished within the app when it is opened.


You help would be greatly appreciated.


Regards

I am using System Status which is currently available in the App store. Whilst there are discrepancies currently with the sizes of the partitions of the first two - the partitions themselves are accurate and exist on this phone.


Im not trying to configure this aspect of the iphone - I keep getting storage errors on a practically new phone with no content - all of it now cloud based and no originals of photos on the phone and no music content. I also recieve notifications for messages in a variety of apps only to open them and the message is not there at all - often the complete history of the message is deleted. Using this app (as i have done in previous versions of ios) I wanted to verify i had plenty of storage - but when i opened it and saw the partitions it looked a little strange. Google results only returned jailbreak code and references for older ios versions using the 3rd and 4th partitions - which should be impossible on 11.1.1 - so its even stranger. Hence my post.

The usual pop up warnings that my device is running low on storage - and it redirects to options to optimise that storage. My apps take up practically nothing, i have no photos or videos as they are all safely in the cloud to optimise storage. under settings>general>iphone storage i have 16.7 of 32GB used - however the error pop ups relate to the device being low in storage and not icloud storage of which i have ample having upgraded to 200GB recently.

The device runs exceptionally hot - and the last two updates have resulted in associated analytic reports titled "com.apple.MobileSoftwareUpdate.UpdateBrainService" with a bug type of 202. i wont pretend to understand these reports - but upgrades generally dont produce them and but i dont know enough to be certain that they do not in Ios 11. Irrespective the upgrade has occured successfully even if indicated to have failed in the analytics report and my system info clearly has me on the latest ios 11.1.1 - and have just been offered 11.1.2 as this is being typed. Being an iphone 7 for some reason my system build in these reports is 15B93 yet my system build is 15B150 in about my iphone - which is iphone X no?


Sorry for the extra detail - I was expected partition 1 to be the system / and the partition 2 to be /var/private where everything else goes. The size through me - possibly explaining the memory error messages - but the other two are new a nd a mystery to me and the context of them in my research has me unsettled in light of messages disappearing that have been notified on the device. As much as I hate looking at logs there is also new Analytics and Analytics Journal reports which occur daily that have some strange variables in them that again have no method to investigate that repetatively use the following commands that cycle through most apps and procresses

{"Message":{bundleID:Com.apple.cryptotokenkit.setoken","count":4,"duration":28," postion":"foreground"},"name":"comappleappActivation","uuid": xxxxx-xxxx-xxx-xxxx-xxxxxxxxxxxxx" <----unique

{"Message":{bundleID:Com.apple.cryptotokenkit.setoken","count":4,"duration":28," postion":"foreground"},"name":"comappleappUsagesession","uuid": xxxxx-xxxx-xxx-xxxx-xxxxxxxxxxxxx" Identical to UUID below

{"Message":{bundleID:Com.apple.cryptotokenkit.setoken","count":4,"duration":28," postion":"background"},"name":"comappleappUsageLaunch","uuid": xxxxx-xxxx-xxx-xxxx-xxxxxxxxxxxxx"


i rarely pay attention to these reports as they as not something i can understand - but the items highlighted in bold are not the usual apple IDs - they lack the delimited periods. This cycles through every bundle ID i have i guess active in the iphone at the time.


As a i said - odd behaviours - hadnt seen these journals and analytic journal type diagnostic reports - but those odd undelimited comappleapp commands have sparked my curiousity. Its hopefully nothing but putting it out there.

in case it is useful - i dont know - but my kernel version is different to what it should be for an iphone 7


the Darwin kernal version is on my device:

17.2.0 Fri Sep 29 18:14:50 PDT 2017; root:xnu-4XXXX.20.XX~X/RELEASE_ARM64_T8010


where as it should be

17.2.0 Fri Sep 29 18:14:50 PDT 2017; root:xnu-XXXX.20.XX~X/RELEASE_ARM64_T8015 the only such option that exists


Sorryy to be pedantic about this

You really need to stop messing around with stuff you don't understand.

If you're having a problem, follow the standard troubleshooting procedures.


Reboot.

Reset.

Restore iOS and restore backup.

Restore iOS and set up as new.


Test after each step. If it still gives you problems after setting it up as a new phone, make an appointment at the genius bar.

I should clarify. I have not created these partitions - i wouldnt know where to begin to do so on an iOS device. I was hoping that i could have some sort of clarity as to why they are there from this forum and for them to be declared normal and that its nothing to worry about.


I have of course reset, rebooted, restored ios from a back up, restored from an itunes back up and am now using the phone as if new restoring my apps 1 by 1. Hence no photos, no music nothing. But the partitions are still there - partitions i discovered using a tool that helps with memory assessment in iOS that is freely available from the official apple store. In terms of not understanding things - I understand enough to know the difference between com.apple.service to comappleservice when looking at an analytical report that has no explanation in any apple manuals or documents or any corner of this forum or beyond.


I will of course be making an appointment at the genius bar but was hoping for some context as to the problem prior to doing so to expedite assistance from an appropriate genius - i dont know what this is. I dont think im hacked - my updates are up to date and there should be no reason not to have faith that for the moment such things are beyond the reach of any menacing individual. There are peculiar behaviours on my phone - the kernal version is correct but for the wrong device - and whilst geniuses are good at what they do - the knowledge of the people in this forum exceeds it beyond the rings of saturn.


I see posts asking what is happening with their phone and they cant answer from trawling through logs and going bonkers. Im not that person. I have an empty phone with storage issues, message notifications presenting and disappearing within the app and weird reports that have some unusual unapple like commands that I dont claim to understand but can spot repetative commands pretending to be apple from a mile off. I thought i would get more discussion than turn the phone off and on - reset it - reset it as new - and go to the genius bar and be at the mercy of a diagnostic report of the first and second partitions.


Apologies for clearly wasting your time.

Apple NEVER intended for you or any other end user to have access to the file system in ANY way. The fact that you don't understand what you're seeing is not surprising, since Apple has not published ANYTHING intended for end users regarding how internal storage is partitioned or used.


Apple is not likely to assist you with your queries in this matter since it is not something you are supposed to be looking at, much less messing around with.

I should clarify again - I’m not messing around with any of this - I’ve simply noticed it in a basic function of the app system status which is available on the App Store. I don’t have access to file systems - just a list of storage partitions on the device. Here are some screenshots:


What I expected to see but the sizes are strange:

That is the extent of my fiddling thank you. As stated behaviour has been odd on my phone in regards to storage - this is app from the App Store that reviews storage. I haven’t created these last two I simply ca n view them - nothing more

No I have no intention of manipulating these items, nor do I want to know how to do so. My device is not jail broken - is running 11.1.2 now and these items remain fixed in place - memory levels in all remaining constant after the update.


So please - now that the store won’t help me - perhaps someone here could try and do so knowing that i have discovered these - do not wish to create more of them but would like to know what they are. Thank you

Well as said, Apple did not released any info on storage management & partitions.

Best you talk to the app developer about the info you're getting.

I have and the partition details is correct and the sizes of the first two partitions being identical are normal and indicate the new APFS Where storage is more freely interchangeable


The remaining two are most definitively partitions on my iOS device
