Android Studio BroadcastReceiver Not Working in Android 6.0

Question

So I'm trying to get Incoming Calls and SMS details in my app. I have tried the code shown below and it works on Oneplus 6t (android 10), Moto g plus (android 8), and Samsung M51 (android 10) and it is working as intended. but when used on Redmi Note 3 (android 6.0.1) the SMS part works but the incoming call part is not working. I have tried to look up on google and Stack Overflow but nothing has fixed the issue yet.
