There can be many reasons
- check your lowest Android version in Gradle file
- How you shipping the apk
Some people have answered to your question try that
And if your app is open source then share the project with me I'll have a look and test in different devices

If your friend has xiaomi phone then apk will not install. solution : you need to sign the apk (you can google this) before sending
