Samsung Galaxy S2 shuts off when plugged in. The screen goes black then a grey empty battery appears for a second then disappears. This "flashes" several times in about 4-5 second intervals. I can not turn the phone on unless the phone is unplugged.
If I try to holding the power button for around a minute it then goes to the "charging screen" (the battery with the charging level in green). This happens even if the phone is partially charged. If my phone is on and I plug it in it stays on for almost a minute then the screen goes black, grey battery appears blinks for about 3-5 minutes same as I mentioned above. When the phone is fully charged, when I get it to that state, it does stay charged.
I have taken out the battery, I have tried a different charger. I am convinced this is a hardware problem. Also this started happening about 3 days ago. Any ideas as to what may be wrong are welcome.
