I have an Xiaomi smartphone which came with a pre-installed app for which automatically records telephone calls. The problem is that the programme only records calls placed through the network carrier. I also have on my phone an app which can be used to make calls over WiFi (but the calls are linked to my home landline account). I have tried a couple of other recording apps, but none of them record the microphone when a wifi call is active, or using the app during the call interferes with call functions such as keypad options. Can anyone recommend a recorder app that works with wifi calls????
