This app is as inconsistent as an app can get. It toggles my phone's wifi on and off and said weak wifi even my wifi is fine. But the actual problem is the other side's wifi has a problem. Then today, it decided not to ring or notify me any call at all. Only hours later, it popped up that I missed a bunch of calls. I've seem 10 years old can develop better app than this. Google's wasting money employing these embarrassing engineers. SMDH!
