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

improve your signal strength, particularly if you are indoors.
2. Turn your phone off and then on again.
Press & hold the Power + Volume up buttons simultaneously, 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.
