Hey Sarsoora772,

Welcome to the BlackBerry® Support Community Forums.


I would suggest removing BlackBerry® App World from the BlackBerry® smartphone, then reload the BlackBerry® device software to repair any issues with the device.  

Once you have completed the clean reload, then reinstall BlackBerry® App World from the Browser at www.BlackBerry.com/appworld.


How to clean reload of the BlackBerry® device software:


I hope this helps.
