Here are other experiences I like to share.
Recently i discovered something else. It's about
api.smoot.apple.com. It seems to be a remote keylogger service from Apple.
More details here:
Looking through some log files today I found something strange : TCP_MISS/200 4931 CONNECT api.smoot.apple.com:443 - HIER_DIRECT/17.252.11.253 - TCP_MISS/200 4656 CONNECT api.smoot.apple.com:443 -

Every keypress on your iPhone or other iOS devcies is sent to api.smoot.apple.com, along with very accurate latitude and longitude and device information. Probably the same problem for iOS based devices (Apple Watch and Apple TV). It can't be disabled. Also not under the current iOS 13 version.
1. I tried it myself and reinstalled iOS on my iOS devices (clean install). afterwards I disabled all spotlight, siri, keyboard, background app refresh options under Settings. Also deleted all stock apps.
2. Then I activated mobile data so that you can see under iOS 13 Settings -> Cellular what kind of apps and services send data. although I deactivated all apps for cellular except Safari.
3. After a while the category "Uninstalled Apps 0,5 KB" always appears under iOS 13 Cellular list. After some time, the data consumption for this category also increases.
4. The problem is that I didn't uninstall any apps and reset the list several times. After a while, when you do something with Safari or Homescreen search, it will randomly reappear there. I tried everything, installed the current iOS 13 beta version and rebooted the device several times.
5. A user gave me the tip to use a local VPN on the iOS device to see what it is. I then loaded AdGuard Pro and Charles Proxy.
Download AdGuard Pro — adblock&privacy by Adguard Software Limited on the App Store. See screenshots, ratings and reviews, user tips, and more games like…
apps.apple.com
Download Charles Proxy by XK72 Limited on the App Store. See screenshots, ratings and reviews, user tips, and more games like Charles Proxy.
apps.apple.com
6. I then activated the local VPN and after a few seconds later in the protocols the iOS device connects to api.smoot.apple.com.
I could reproduce it multiple times and again and again no matter on which iOS device or iOS version. Also with my friends it is the same. And they can test it themselves. It is 100% reproducible.
