- Check the signal strength on the phone screen, and move to an area with better reception.
- Remove any accessory covers or shells from the phone temporary to check if covers affect the phones's signal strength.
- Check to see if the screen stays active while in a call, if you have a touch screen. You may accidentally press the hold call or end call button on the screen with your cheek.
If you continuously experience low signal strength in a certain area, the network coverage there may be insufficient. For more info, contact your network operator.
