Several weeks ago I created a tutorial based on the relocation of apps/data to the SD card.. using my LG Rebel, which allows most of my apps to be relocated, I did the tutorial based on moving my Opera Web Browser. During that time.. Because the tutorial was left open for comments, Members comments/post their views on my tutorial claiming it's not necessary to relocate apps.
In my opinion and if the app can be relocated, then by all means relocate them. This si done when one would access: Settings > App Manager > Select the app > scroll down each app and look for the "Move App To SD Card" message within the app. If the message has been grayed out, this means the app can't be moved.
I'm hoping to recreate this tutorial and very soon.. Just waiting on the admins verification/validation of a new category just for this purpose.
