Your phone will not switch on.
The battery may not be able to hold a charge, and you will have to replace the battery.
If you have replaced the battery and the problem is not fixed, you will have to replace the logic board.
If the phone seems to be working but the display is black, then the display is broken and you will need to repair or replace it.
There is no sound coming from your phone.
Increase the volume on the device by pressing the increase volume button on the left side of the device.
If you are receiving no audio during a call, check to see if the call is connected or if it was somehow disconnected. Press end to hang up on the call, and redial if the call was disconnected.
If you are still receiving no audio signal, call voicemail (press and hold "1" on the keyboard), and listen for the recorded message to check and see if your phone's speaker is malfunctioning.
Some of the buttons on your phone do not register when you press them.
If the connection between the board and the phone's keypad is malfunctioning, replace the phone's logic board.
Dust or sand could be blocking the connection to the keypad. Water or other liquids may also be shorting out the connections. You will have to replace or repair the keypad.
No sound comes out from the speaker phone when it is in use.
If speaker phone fails to work, there could be a connection problem. Outer casing must be removed to check for any problems. This problem can be fixed either by replacing the speaker or by repairing any breaks in the wiring.
Your phone turns off as soon as it is disconnected from the charter
If the phone turns off immediately after you disconnect it from the AC charger, the battery is likely dead and you will need to replace it.
If your phone dies from a drained battery and does not resume power after being connected to the charger, make sure the charger is properly plugged into the phone and the wall outlet.
Referring to the problem above, if the cord and the charger are plugged in all the way to their correct locations, the charger is broken and will need to be replaced. Check your nearest Samsung Distributor for a replacement charger.
