I was an Android beginner, I know nothing of 'hacking' some Android stuff. I found several issues of this case but no one that I look pretty ideal for my case.

My Samsung Galaxy Ace 2 has been inserted a new SD Card after a several time using no SD Card. That makes the system create sdcard in it's internal storage. Then my storage information (Setting -> Storage) become 3 parts, which: Device memory (internal), USB Storage (internal), and SD Card (extSdCard). This thing become very annoying since my internal wasn't so big.

And when I open my Gallery it pop some notice There is not enough space (0 MB) in your device memory. Delete some files. And always redirect me to the Files. On my Files there is 2 folders, which: extSdCard and sdcard0. On the setting of Files. I can't change the Set home directory that refers to /storage/sdcard0 to (my hope) /storage/extSdCard.

I done trying to moving all apps to internal storage with hoping that USB Storage not full, but it doesn't give any good solution just yet. I read several post and forum, also several solution using adb but I don't think those solution can manage all problem, since because of this case, I can't save any voice note or picture from social chatting apps, in some case, I can't receive any bluetooth transfer also.

So I want that USB Storage begone, and my sdcard0 was symlinked to the real external SD Card, or another step that make my system become like the old like Android system. Please help me. Thanks a lot before.

FYI: right now, my phone isn't rooted yet. But I can root it anytime, if it really needed.

  • I'm not sure whether it works on the Ace 2, but you might wish to take a look at External 2 Internal SD. Was originally written for the S3, but should work for other devices as well. Please report back whether it helped.

  • @izzy: I don't really know about the system of Android 4.4. But how if I just re-install the whole system of the Android while SD Card was inserted. Do you think that way can work? I mean, the ExtSdCard can be directly known as the sd_card0.

  • I don't have 4.4 on any of my devices (and I don't want to). But I'm afraid that would again install anything on internal ("primary storage"). Maybe this is helpful: Installing to SDCard by default? If your device is rooted, you might also wish to check our link2sd tag-wiki.

  • I'm really sorry, I meant 4.2 :P. Ok I'll try to looking on it also. I had tried your first solution but still not doing fine and there's some step I should notice more carefully.

thanks for upvoting this question but I'm afraid I still have no answer until this day either majority people. But let me share my latest research about this case which actually would be lame because I post this question pretty much long time ago. So, here it is.

When I do my research about it on the device, I try to root it, try to swapping the the storage and whatsoever (please notice that my Android's knowledge was not too much, so I think I may not trying all methods). It's all result nothing but pain and brick phone in the end of the day.

So I bring my phone to Service Center and after they re-install it I asked them about that case/issue, they trying to answer with 'not-clear-answer-to-preserve-reputation' answer, until I force them to spit the truth. Then finally they says that how Samsung Galaxy Ace 2 works. So, that's is, my last conclusion that this phone was made for experiment or whatsoever. I face this kind of experiment issue form Samsung not just once

So, I hope this story can brought us some unclear light to overcome the unclear darkness that coming from this phone (you can skip this last unclear sentence :p). Peace out :D
