I think you are having an android cell phone and accroding to your problem i guess you might try to update your cell phone from ICS ie. icram Sand witch to 4.1 series Jelly bean . There are some bugs in some sort of handset specially while updating Jelly Bean into it all you need to do is ask for the support in Authorized SAMSUNG website hope this information may useful to you.
Better get it resolved from a authorized person because I have to completely loose my phone when I gave a local person to do it!!! Your phone would surely work better and it will be with all the upgraded stuff!!
