My Samsung Galaxy will not charge either on the wall charger

Customer Question

My Samsung Galaxy will not charge either on the wall charger or car charger. It doesn't appear to be making a connection with the charger. First time this has happened! Any suggestions?

hi, thanks for using JA:

The very first thing to do is a full reset of the Galaxy. With this process we will verify that the problem is not a software issue. To do this follow the steps outlined bellow. Please note that all data will be deleted from the Samsung Galaxy S as a result of this procedure. This process does NOT delete data stored on the microSD card.

1. Turn the power off. If your Samsung Galaxy S is frozen, pull the battery out and reinsert it
2. Hold the Volume Down button
3. Press and release the Power button
4. You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage, and Simlock
5. Select Clear Storage by pressing the Volume Down button
6. Press and release the Power button
7. Now simply confirm your decision: Volume Up for YES and Volume Down for NO. After doing this check if the phone is charging again. If not, go to the next step.

If resetting the phone doesn0t solve the problem, then the cause of the issue is the phone hardware. The problem is related either with the battery, the charger or the charger circuit in the Galaxy. The most probably cause is the battery or the charger.

We can check if the charger is in good condition with a multimeter. Do you have one?

The only way totest the battery is by installing other battery on your Galaxy S, and testing if it charges. If the phone charges the battery when the charger is plugged in, them the problem is the battery.

Regards! If that helped, don't forget to accept my answer!

I did not get the reset menue. My model is the GT I9000 M. Is there any way to clean the connection on the phone?
Expert:  Eng. Andres replied 6 years ago.

Yes, you can clean the contacts if you suspect that it's the problem. The best way is using Using Q-tips and a very small amount of medical alcohol. Unplug the phone from the charger and clean the USB port contacts. Then unplug the charger from the wall outlet and clean it, using the same method. Afterwards, wait 15 minutes to dry the contacts. You can now test if the phone is holding a charge again.
