Before I bought the pro version I told you that my friend told me that the call recorder icon stuck on the screen after the call is ended. You wrote me that you didn't know about it and this is not need to happen.
I bought the pro version 2 month ago and it works great ! Lately, this problem happen me too. I hang-up the call and the call recorder icon stuck on my screen for long time.
I attach 2 photos that you can see that the last call was at 14:38 and the icon stay stuck on the screen at 14:43 (5 minutes after that I hang-up the call). I check it again and it's stay stuck for long long time (something like 2-3 hours).
My device: LG G3 (D855). Android: 5.0. ACR version: 14.8. Thank you ! Ohad.
