The phone is not compatible

"This app is not compatible with your device" appears when the Android version or the processor the package wants does not match the phone.

• If the package wants Android 8, a phone on Android 7 will not install it.
• A 32-bit phone will not open a 64-bit package. The other way happens too.
• A package built for a tablet is not treated as compatible on some phones.

The Android version is under Settings, About phone.
