No USB / Wrong info about connection status
my I9100 acts weird since a few days.
When I connect it to power or USB, it seams not to act correctly. Before it gave me a indication sound, now it doesn't. Same, when I disconnect it. When my phone is fully charged, I get the "100%" icon on the top left. But it does not go away, when I pull off the power cable. It stays there forever (like I would never pull off the cable).
USB data connection does not work. My S2 acts like it wouldn't be connected to USB. (Internal and external SDs are working fine on the phone).
When I turn my phone off I can not start it again. It shows the battery-loading-icon, even if it is not connected to power. The icon then changes into an icon which looks like a thermometer and I can not start the phone. (The phone or battery is not hot or warm at all). To start it, I have to plug in the power cable, then it works.
