How to trigger a sysdiagnose on iOS 14.4+ device

Question

I have an iPhone 8, and I'm trying to trigger a sysdiagnose with iOS 14.4 and up. You'd think that this is well-documented, and it is, but I still can't get it to work.

Here's what I've tried:

If you go to the Profiles and logs page here and filter by iOS: https://developer.apple.com/bug-reporting/profiles-and-logs/?platform=ios

There is documentation labelled "Sysdiagnose" which takes you here: https://download.developer.apple.com/iOS/iOS_Logs/sysdiagnose_Logging_Instructions.pdf

The instructions are pretty straightforward.

Hold the two volume buttons and the side button for 1-1.5 seconds.

Expected results

It says a screenshot will be taken and a sysdiagnose will be triggered.

Actual results

The Emergency-SOS/Power-Off screen shows, and the SOS swipe gradually counts down and starts making loud-AF emergency beeps while it counts down, sort of like when you get an Amber Alert. This is sort of terrifying.

There is no screenshot taken, and if I wait, it does not yield anything resembling a sysdiagnose in the Settings.app > Privacy > Analytics > Analytics Data

Other things I've tried

• Searched Apple's forums, tried all options recommended here: https://developer.apple.com/forums/thread/80811
• Tried using the home button instead of the side button... same results as above.

Thanks for any help or clarification!

Do I really have to risk accidentally calling the Police (or whatever SOS does) to trigger a sysdiagnose?

Are there some steps I'm missing? Like my device should be plugged into my mac and debugging on XCode? Or showing in the Organizer?

Answer 1

您需要在 1-1.5 秒的时间内快速释放所有按钮。如果您按住按钮的时间较长，则不会起作用。

如果您在释放按钮之前等待手机确认系统诊断已触发，那么您就做错了。在 1-1.5 秒内释放它们。

第二，

如果您正在等待按照文档说明进行屏幕截图，那么这种情况不会发生...至少您习惯了屏幕明显缩小并在左下角显示屏幕截图的方式几秒钟。这不会发生，所以不要指望这表明您的 sysdiagnose 已成功触发。

第三，

当您查找 sysdiagnose 文件时，您确实必须一直向下滚动日志列表等，直到您真正看到名为 sysdiagnose 的内容。

在查看之前请务必稍等一下。

第四，

如果您感觉到轻微的振动并且没有其他反应，那么您可能做对了。

我尝试清除此列表，以便更清楚我的 sysdiagnose 在哪里，并且同步您的设备或重置位置和隐私设置不会按照此处的建议进行操作：https: //discussions.apple.com/thread/250201909

希望这对像我一样笨的人有帮助。
