Digging up something old …
When I went through all the settings in 15.1 I found those here, perhaps they were there in 14.1 already? But doesn’t matter much, there will be a switch to 15.1 somewhen sooner or later …
Settings
- Google (Services & preferences)
- [Internal] - Google Play services modules
This seems to have all the info about when each Google Play services module was last updated.
But beware … If they were installed with TWRP while TWRP didn’t have the correct date and time, those modules can end up with a last updated date in January 1970 .
