I primarily use my iPhone as main phone, but purchased the samsung phone as separate business phone. It basically always sits on the charger and one day I was checking my phone and this came up.
When in charger it just keeps flashing this screen every 5 second. When off the charger it is non responsive to power button or a hard reset (volume down, power button). Even after full battery drain and powering back on it shows the same symptoms. It does respond to the custom OS (volume up, power button, home button), but I have 0% knowledge about that feature and still need to make copy from my contacts/photos etc...
Anyone have idea's?
