How do I find out what's wrong with my phone?
Apps like Phone Doctor Plus, Phone Diagnostics, Phone Check and Test, and TextX can run a battery of tests to check the touch screen, audio, video, camera, microphone, sensors, and other components of your phone.
Why mobile is not working?
Restart your device.
If restarting doesn't work, switch between Wi-Fi and mobile data: Open your Settings app and tap Network & internet or Connections. Depending on your device, these options may be different. Turn Wi-Fi off and mobile data on, and check if there's a difference.
