Hi, so the battery came with my galaxy s3 R530 has died and I just replaced a battery from eBay, but now my phone is having a weird issue--- it will only charge when the phone is off while charging with USB cable. I am waiting for another battery from mpj for troubleshooting. Does anyone know any other possible reason causing this issue? Thank you.
I'd recommend just getting an OEM battery. Try that and if it doesn't work contact a repair service or the phone carrier for replacement or fix.
I had a same problem with my s3 galaxy mini. apparently the samsung technician told me that the motherboard has rust inside probably because of my phone often has moist with the use of plastic phone protector. Since samsung wants me to replace the whole unit. I opted to search for a freelancer technician to help me solve the problem. The technician told me that the connector from the charger and phone has rust on it, he cleaned the area and was able to charge the phone again.
