over the proximity sensor to see if you can turn the screen off and on.

Calls are dropping
1. Check your signal strength:
• Weak signal from your cellular provider is a common cause of dropped calls. In the
status bar , see how many bars your network connection has. If you see only one or
two bars, change locations to improve your signal strength, particularly if you are
indoors.
2. Turn your phone off and then on again.
Press and hold the Power button, then touch Power off . Then turn it on to establish a new
connection with the network.
3. During a call, check that the proximity sensor works by covering it to confirm that it turns off
your screen, preventing accidental touches during calls. You can also download an app to
automatically lock your screen during calls; search for “call screen lock” on Play Store.
4. Use safe mode to see if apps you installed are causing the issue and uninstall as needed.
