[Galaxy S 4 i9505 Android Development] MetaMav:
I'd like to share some feedback after using this mod for a few days.

First off, all of the features described in this mod are working very well. I have seen no performance issues at all. There are a few small things I would like to point out:

The cosmetic issue of the internal and external storage size being the same does not bother me. However, I noticed that android still respects these values when calculating space requirements. This becomes an issue if you have only 500 MBs left of your real internal storage and you try to install a 1GB game from the play store. This is a non-issue is you never add anything to your internal storage. I found this out because I used this mod on a fully loaded s4 with only ~800 MBs of storage left on my internal and installed this mod without deleting any of the files on the internal afterwards and then trying to install a 1.2 GB game.

Another issue I noticed was media, such as ringtones and pictures, being stored on your "new" internal storage (sd card) being usable or not found after a reboot. This mod does not take full effect until approximately 20 seconds after the phone has been booted and Touchwiz loaded. What I guess is the problem is media scanner runs before the storages are swapped and only loading things that are stored on the real internal storage. This makes the gallery unable to view photos previously taken. The gallery understands that there are photos on the real external storage but cannot load them because the real external storage has now been swapped to be the internal storage. This same thing applies to ringtones saved on your sd card.

I solved the ringtone issue by transferring the ringtones onto the devices root file system so that it does not matter if the internal and external storages are swapped. I solved the Gallery issue by downloading the Fish Bowl Photo Gallery app from the play store and running the media scanner option. This re-scans the file system and fixes the Samsung Gallery app not finding photos. This Gallery workaround would probably work for fixing the ringtone issue as well if it actually re-scans the file system using the android media scanner (which I'm not positive it does).

One other app that had issues with the mod loading after boot was the SwiftKey keyboard app. This apps loads its language pack on boot before the mod kicks in. This creates the problem of the app needing to redownload the english language pack everytime I reboot my phone even though the files are clearly on my "new" internal storage. I solved this issue by copying the language pack files from the "new" internal storage to the "old" internal storage (/sdcard/internal_sd/0). This allows the app to recognize the files on boot and fixes the issue.

[MENTION=2596418]mattiadj[/MENTION], I was wondering if maybe some modification to your code could fix these issues. Maybe being able to have this mod load before the media scanner runs would fix this issue. Or, having a way of running the media scanner after the mod kicks in. I do not understand the limitations of your mod or the PHP scripting involved so I'm just inquiring. If a fix isn't possible maybe you could add my workarounds to your guide.

Hope this helps some people! Great Mod! :D

**EDIT**

Great app on the Play Store called Media Scanner that is a great workaround for the gallery issue. Has a nice looking widget too.
