I was installing some applications in my mobile which were not available on Google play store.

I downloaded the APK of those applications and tried to install them. During the installation process my mobile phone hanged, I turned it off. But after that it couldn’t be booted, whenever I tried to switch it on it stuck at Samsung logo.

I purchased a Samsung mobile two years back it worked well for 1 year but now it started hanging, after hanging I have to off its power and then it starts working properly but then again hangs after some time it hangs. Only a few applications are installed, SD card is empty. How to get overcome of this problem please suggest!
