My first ever smartphone experience was with the HTC Touch. The phone at the time was being dubbed the iPhone killer. It had a small touch screen and even a stylus. Windows mobile 6 was the operating system. As soon as i found out I could hack it to install Android that is exactly what I did...
My mom bought this phone a year ago,Galaxy 4 Ace,kept using it while charged,and left it overnight to charge.Next day,it was not working.My pc would not detect it either.Even with the drivers installed.
I used an LED to check the battery.Working fine so I believe that it is a hardware problem...
