Note 8 fast charge issue

JUMP TO SOLUTION

As of today my fast charge is not working correctly. When I plug my phone into any fast charger I get a double charge sound. It will say charging, then disconnect and say charging again and then charge but no fast charge. I had a moisture error earlier and after drying out the port all was fine. I come home plug up my phone and I get the double charge thing with no way to fix it. 

edit 1: I will add this I only get the double charge sound if connected to a fast charger. Connected to a normal charger it just charges. 

edit 2: also just discovered I cannot fast wireless charge either. so no fast anything 

edit 3:when phone is off it says there is a moisture issue and will not charge, but phone will charge once it is on. again no fast charging of any kind.

For the moist warning, I would recommend trying to blow in the charging port and gently shake the device. For the charging issue, I would recommend a service repair. Please send me a private message with your full model number, IMEI, and zip code so I can provide you with further troubleshooting steps.

Hello there @ScarletImpala13 and @user4I9UPhGrzO

 

Thank you for reaching out and posting. I am sorry to hear that you are both experiencing this error.  I know waiting for the device to charge on conventional charging speeds can be a quick route to frustration. Could you try placing your phone in safe mode for me, just to rule out any possibility of an app conflict?

 

To do that, you can start with the phone turned off. Then press and hold down on the volume down button when you are powering up the phone. Keep the volume down button held down till you reach the home screen. If successful, it should read "Safe Mode" in one of the corners.

 

This temporarily deactivates any app that was not preinstalled on the phone, and is how we test to make sure errors aren't caused by apps. Test the charging while your phones are in this state, and let us know if there is any difference.

I've tried safe mode as well and there is no difference still the double charge sound when using a fast charger. I've checked the port nothing there I don't know what else it could be.
