As you all know app2sd function was re-integrated back into android from jb 4.2 upwards. The problem is when i move any suitable/movable apps to external sd card wether through stock option or third party app2sd app function it all seems to work without problems until you restart the device and then you get a greyed out app icon with an "sd" sign at the bottom corner of it and when you try to open the app it says "app not installed".
Please someone help find the solution. Thanks kindly.
information about my phone:
samsung galaxy s3 lte i9305
android JB 4.3 stock vodaphone uk rom
NOTE: the only thing i can think of is that when i was on previous rom 4.1.2 i rooted it and installed cwm also i also flashed a file called REMOVE.BOOT RECOVERY.P . but i should think after updating to the newest rom all would be reset but anyway thats about all i can think of at this moment.
