The reason I'm asking this question is because I think this might be red flag and want to check, just in case.
I have a Unity project (but there's nothing specific to Unity in the question, so I don't add the tag). Previously, it was built for arm only, and when I uploaded it to Google play, "Native platforms" property said armeabi-v7a. Now I switched to a build that supports both arm and x86 architectures, and the "Native platforms" says "armeabi-v7a, x86". However, the "Supported Android devices" property has a comment "4 added".
Shouldn't the amount of devices that were added because of a new architecture be bigger? Is this amount reported by google true, and if it is, why?
All the Intel based Android devices that are commercialized not only support x86 but also armeabi-v7a (through an emulation layer).
That's why adding x86 binaries to your app only added 4 devices to your list. But by doing so, you greatly improved your support for all the x86 devices that were only "compatible" before.
