"Drop in support for Phone devices" on Google Play

I am updating an old picture book app on Google Play after a couple of years. It looks like my new version means dropping support for 588 device types. Is there anything I can do to prevent this? Or just inevitable?
Thank you for any suggestions.

I think it’s inevitable. It means users on these devices can’t get an update of the app. It’s probably all the devices that are running Android versions earlier than 5.0.
Did you check how many of your users are even on these older Android version?

You can find it in the developer account in statistics.
