App opens and closes itself immediately or within a few seconds. This problem you might face with Jailbroken or non Jailbroken iPod Touch, this problem occurs when some of the application are using the memory even after you have exited them, be careful when you are using backgrounder application. Now to solve the problem I will be providing some very basic troubleshooting steps.
First the application problems:
App opens up and closes immediately
App opens up and you even started playing and then suddenly it closes itself within a few seconds
Now these are similar but could be two different problems, follow these troubleshooting steps to solve app instability problem:
First: You must try is a reboot or restarting your iPod Touch( iPod Touch 2G jailbreakers have to follow the boot process again). Restarting your iPod refreshes the memory of iPod Touch and chances are that your applications will be running fine after a restart. It is also recommended that you should restart your iPod Touch once in a week.
Second: The app doesn’t meant for your iPod Touch
Third : The app isn’t available in your country and you might be using .ipa files for installation, if you have this problem with .ipa files then try another version or latest version of the app and it might work.
Fourth: Use applications that frees memory, i recommend a restart though.
Most of the time, a simple restart solves the closing app problem.
