iphones has reset itself automatically
Having been working with Apple DEP (now ABM) for the last 3 years, I can tell you that I have not seen any instance of a user reporting a device wipe / factory reset after an iOS update, Self-installed or MDM console pushed.
I can tell you that after an auto-update install for iOS, the user can get to the Hello screen, and go through some of the setup screens, but it always gets them back to their device with their apps.
Did the user go through the same 'SetUp' screens you have configured in InTune for your ABM / InTune integration?
If you have configured 6 items to 'Don't Skip' for the InTune MDM Profile and the user did not receive all 6, the device was not fully wiped.
Or, even simpler, did they see the 'Remote Management' screen?
Yes: The device was wiped.
No: The device was not wiped.
A full device wipe will reset everything, and the phone will start fresh and check with Apple Servers to 'Activate' the device.
If only 3 users out of a large deployment are experiencing this, I generally find that the reporting users did something different, or are not reporting the issue correctly. It may seem to have been wiped, but it wasn't really wiped.
Answer to your questions about the logs:
Logs to review: for MDM console issued device wipe, you already mentioned that you checked. An Admin initiated wiped will show the admin username and the 'MDM Break' entry in the log on the day that the user reported it happened.
Also, does the Enrollment date in the console match the reported 'wipe' date?
Device logs: Given that you are using ABM and AC2, I assume these are company owned devices. If you can get physical access to the devices, you can install Xcode on your Mac.
Open Xcode
Click on Window
Click on Device and Simulators
Allow the device to Trust the Mac (enter passcode on device)
Click on View Logs
If you see logs with a date prior to the date the user reported the wipe, then, the device was not wiped.
Hope this helps to first of all, determine if the devices were actually wiped.
So we increased the configuration where the device gets wiped after so many unsuccessful tries. we increased to 11 tfrom 5.
we are going to keep an eye on it.
