The apps that were moved/installed on SD card fail to display on the application drawer or at home screen. When I go to Play Store, all installed apps on sd card not found, it's asked me to install application. But the phone detected the applications, wen i navigates to apps installed on sd card, they are all there but it is not visible(in grey color ). Any solution for this?

On very rare occasions it displays all the apps. I had tried restarting the phone, unmount, remove and mount SD card, reinsert battery etc.

The only thing I'd done on the phone before the incident is;
1. Try to root d fone using Root_with_Restore_by_Bin4ry_v18_2.7z, by didn't notice the problem.
2. A friend removed the sd card and inserted it in his phone, it was after this I observed the problem.

Note: I'm using tecno L3

Any solutions?
Ur reply is highly appreciates!
