Hi. My phone has two problems. One of them, wi-fi network isn't working. When open the Wi-Fi, there is "opening" letter on the screen. And there is nothing happens. Another problem is my phone's Hotspot, like wi-fi. I touch Hotspot button and it is not working. This problems appeared two days ago. My build number is 32.3.A.2.33 and Android 7.0 March update.
