If the phone does not turn on, plug it into the charger, wait a couple minutes, and then try turning the phone on again. If nothing comes up on the screen, listen for the start up jingle that the phone plays. If you hear nothing, the battery may be the problem and may need a replacement. If you hear the tune, see the next section for further directions.

Antenna No Longer Retracts into Phone ¶ 

The antenna can be a pain. It breaks, snaps off, falls out, or bends and leaves you without that increased reception.

Antenna in wrong position ¶ 

Power off your phone by holding the end call button for a few seconds, and wait for the phone's "powering off" screen. Once the phone is off, remove the battery from the phone. You will notice a little black "straw" on the left side of the battery compartment; this is the housing for the antenna. There is a little plastic nub where the housing is supposed to sit. If it is not resting in this spot, move the housing over to this spot. This should realign the antenna in the correct spot and allow it to retract. If the antenna still does not work properly, read on.

Damaged/Broken Antenna ¶ 

The antenna could be internally damaged. Follow this step-by-step repair guide, Samsung SCH-A310 Antenna Replacement, to replace the antenna.

Keyboard Malfunction ¶ 

The keyboard can cause multiple problems for users. Sometimes the keys stick or spilled liquid causes some or all of the keys to stop working.

Broken Keypad ¶ 

If one or more of the keys is no longer working on the phone, it could be due to either a glitch in the phone or internal damage. If the power button is still working, press and hold it until the phone powers off. Wait ten seconds, then turn the phone back on. Wait for the phone to finish powering up, then try the malfunctioning key(s) again. If the power button is broken, you can try resetting the phone in two ways. You can remove the battery pack from the back of the phone, wait a minute, replace it, and see if this fixes the problem. However, if it does not fix the problem, your phone will not be able to turn back on. We recommend the following to reset your phone to factory defaults, however the proper keys must be working:

  • Press the menu key to display the menu.
  • Press the 0 key to enter the Setup menu, then the 4 key to enter the Security menu.
  • Press 7 to reset the phone. The phone will ask you for confirmation, press OK to confirm.

If the problem still persists, the keypad is most likely internally damaged. Follow this step-by-step repair guide, Samsung SCH-A310 Keypad Replacement, to replace the keypad.
