Edit: I didn't notice there's an SII AT&T forum. If this could be moved there.....
My AT&T SGH-I777, unrooted, stock everything has recently started (beginning and stopping and random) to vibrate and display the "Media scanner running" notification, and show that is it charging (then revert to its normal unplugged state) as frequently as twice a second. This only happens when the phone is unplugged, is halted by plugging in the phone, but may proceed to resume 'toggling' as soon as the phone is unplugged. It happens in spurts, lasting from one second to several minutes, perhaps longer if I wasn't removing the battery to get it to shut the hell up.
When this is happening, the screen becomes unresponsive (or rather, each "plug"/"unplug" interrupts any touchscreen gestures) rendering the phone unusable.
Even more bizzare is that this sometimes happens even when the phone is off
. It will show the battery charging screen either at the correct battery level, or at empty, depending on how long it's been "buzzing". When this happens, it is almost impossible to turn the phone on, since I would need a full uninterrupted second of holding down the power button.
Since this is happening even with the phone off, I feel like it's a hardware issue, but I wanted to see if anyone has had this problem or has any ideas on what might be causing it.
I've thought it could be some foreign object in the usb port shorting it out, but have looked and can't see anything, or maybe a problem with the battery itself supplying inconsistent voltage, but I don't know enough about the mechanics to be certain.
Does anyone now what might be the problem? Has anyone else had this problem?
Thanks in advance.
