Ever since my last update I can no longer hide the chat bubble when I'm on a phone call. Even when I turned off the "display over other apps" permission, it kept turning the permission back on on it's own. Even after I'd turned off the permission that allows it to modify settings. As someone who frequently uses my Bluetooth while using other apps on my phone, I am not impressed in the slightest. You need to fix this, and fix it now!
