Symptoms;
- when switched off and without a USB lead connected the phone display alternates between a battery level indicator (as if charging) and a temperature warning.
Plug a USB lead in to get past this and boot the phone normally - When switched on and you've received a 100% charged notification, rebooting the phone and checking the battery level again, shows the battery hasn't charged to 100%.
I'm trying to force mine up to 100% by rebooting every time it stops charging to charge it a bit more. This might get it over the hurdle eventually... - With no lead plugged in, trying to disable USB debugging mode (settings>applications>development) gives the error: "USB is connected. Remove the cable"
I've got no fix for this yet, except maybe flashing a clean ROM onto the device with the debugging mode already disabled
- Clean the micro USB port- switch the phone off & remove the battery. using some isopropyl alcohol, some cleaning tissue and a toothpick, carefully wipe the 'tongue' of the port, the side nearest the screen primarily Gently tease the tongue up towards the screen also. This assists the lead make contact properly
- Contact a Samsung service centre, giving the details of the problem and that it has reported as a problem globally. As the symptoms can be erratic, they may not see the problem at first, but a skilled engineer should be able to replace the USB port in under an hour (according to reports)
- Replace the USB port yourself. The part can be found at http://www.tvc-mall.com/details/Samsung-I9100-Galaxy-S-2-Dock-Connector-Charging-Port-Flex-Cable-Ribbon-Original-SAMF-I9100/ and detailed disassembly instructions are also floating around.
