Google rolled out the first developer preview of Android P just a couple of days ago and one of the most concerning changes in the updated OS is the removal of custom overlay support. The feature, which was introduced with Android 8.0 Oreo, allowed users to install custom Substratum themes without rooting their devices. However, the much-loved feature didn’t make the cut in the first Android P developer preview.
“Google introduced Sony’s Overlay Manager Service (OMS) in Android Oreo, letting us install custom themes using the app “Substratum”, with the need of root permission. However, OMS was locked down by Adam Lesinski (Google employee), with no apparent or described reason in the March Oreo update.”
