1. Can this be fixed? Did a check on the app block call and it is showing the calls as in SIM2 whereas call were on SIM1.It works better than others but the one thing I didn't like and reason why I uninstalled it is you can't get your voicemail notifications where you can see that you got a voicemail without opening your phone usually that icon will show on the top of a phone so when it says that you have to have all the control of your phone it doesn't let you see your voicemail notification otherwise it would have been on my phone I liked it better than the other ones I've usedIts good Application but seems still need development, The Option which shows SIM Card Choice but Black List and white List keeps same on selection any SIM Card ! There should be Different White List and Black List selection with specific SIM.

3. Sim 1 - allow all calls and sim 2 - block all incoming calls --》sim 2 blocking not working.

4. Swaped the sim cards and tried with blocking all calls from sim1, its blocking call from both the sim.

5. The calls go to voicemail which is good in case an important call comes in that is not in my contacts.

6. Furthermore, now with Android 12 when I want to make a phone call and intended to use SIM2, the apps mistakenly make call from SIM1 (always).

7. It able to block unkown calls in SIM1 only and keep SIM2 as unblocked.

8. It is working well in blocking the calls on SIM2 so far.

9. Only way to get the calls was to switch the dialer back to phone .
