I have an iPhone 5s with following problems;
1. When the iPhone is powered off and charging the iTunes and USB logo are visible on screen.
2. When I press the home button it does not work, voice control gets activated by its self.
3. When the iPhone is powered off, and I connect the iPhone to iTunes it says "There is a problem with the iPhone that requires it to be updated or restored."
4. Voice control would try to call some number.
I got this iPhone in this condition, what could be wrong.
How can I fix it ?
