Hello everyone! I found a samsung galaxy xcover 3 in the trash that would start but not charge when the power cable was plugged in. I decided to try to fix it because I really could use a “new” phone. To my disappointment I found out that the phones usb port is soldered directly to the mainboard. I thought I’d just give it a shot (eventhough I never soldered smd before) and bought a replacement port. Teardown was succsessful and I got digitizer and lcd off without damaging them. But desoldering the port was very messy. To my surprise the phone still turned on and seem to function normally after I finally managed to get the port off, I could have sworn I already bricked it. The desoldering must’ve taken like an hour lol. After cleaning up the flux-solder mess I saw that one solder pad was missing. Does anyone know what that contact was for and if there’s any change of fixing it? what would happen if that one contact just isn’t connected? Here’s a foto of the contacts:
@lorebu at this time the only way to determine what that particular pad is responsible for is by replacing the connector properly and then giving it a try. Samsung defined this pin as a “Customer_use” and whatever that means is unclear
Give someone the chance to solder this on right since it may just be a useable phone :-)
Hi Doing a zoom in on it as best I can it loooks like it is not going anywhere> But I could be wrong The soldering is not good has you know yourself I would advice taking it to a repair shop that does microsoldering. They will be able to do a better inspection of the pad to see if it is OL (open circuit) or connected to another part of the board I could not find any board layout or schemetics for this model of phone . If we could we find out in no time about where this pad does
