Why does Google Play say app is "incompatible" I have an app that I want to install in my android phone. Unfortunately, it is marked 'incompatible'. I might try to upgrade the system to install the app, but first I'd like to know the exact reasons the app is 'incompatible'. I.e. what are the 'variables' my phone gets wrong to be unable to install the app.

Is there a generic way to do that?
From Google App compatibility with Android

When searching or browsing the Google Play Store app, you'll only see apps that are compatible with your device. When using the Google Play website, a device will be grayed out if it isn’t compatible with the app you’re attempting to install. This usually occurs because the app isn’t available in your location or designed for your device's screen size or version of Android
Developers have the ability to target applications to specific devices based on screen size, mobile service provider, location, and a number of other factors. App compatibility can change over time.

Is there a generic way to do that?


From the same source


For compatibility information about a specific app, contact the developer directly using the information provided on the Google Play listing


For some apps, reason is displayed ,as in screen shot below from my device ( version incompatibility )



Few years back incompatible apps would state reasons by clicking on a plus sign next to app as mentioned here
