Develop Bugs

I'm stumped

Hi everybody. I am trying to get my daughters phone set up. She is 20, very busy, and I only get the phone an hour or so at a time which is frustrating. I have modded my own android phones(Note, Infuse,Gnex) so I'm not a beginner, but this captivate glide is acting a little different.
Here is where I am. CWM is installed and a backup of 2.3.6 is done, and a copy saved on my laptop. I have ardatdat's 1.2 version kernel ready to flash for root and to remove the IQcarrier junk. She will probably stay on stock, rooted since she is not into teching her phone but does want to remove ads and maybe tether to a tablet occasionally on ATT without a tethering plan- tit BU and freezing or removing the tethering manager.
I am having trouble getting the phone to recognize an 8 gb sd card. I have repartitioned it so more apps can be moved over(primary fat32 and logical-ext 2) and split the card to 4gb and 4gb.(approx)- even when just left as a one partition card with 8gb fat 32 the phone just won't recognize it. I put the old 2gb card into the phone and that one is recognized but is from a non android phone- an LG xenon.
I want to put the zip files to flash on the external sd card along with a few apk's ti install with the appinstaller. But.. the phone won't see the files. Do I have to use the internal storage?????
Don't have the phone now- it's off to work with her. So I will try later tonite. Any suggestions??
Thanks. Open for any help here. I have never had this much trouble before! Have searched for sideloading apk's, but from what I am finding it has to be rooted first??? I have checked unknown sources for install of 3rd party apps and usb debugging also checked.
I will continue my hunting for info. I'm sure it's just basic stuff I'm just not seeing. Thanks again

Ah. CWM Recovery is not compatible with the external sd card, I believe. It's located under /sdcard/external_sd but the zips are invisible in the recovery. So yes, I think you have to use internal

Thanks for that. Did not read that anywhere! Any idea about apks on the external sd card?

Ive tried that too... The apps are located in the data partition on the kernel so that is already directed to internal... The only things most people put are Media like movies because music players scan the entire /sdcard partition and the /external_sd is in it.
Hope this helped ^o^

You may need to format the sd card in the phone itself to get it to show up, some people have had problems with cards formatted in other devices or a pc.
I haven't tried a dual partition card in the Glide, but I came from a Motorola Flipside which had an absolutely tiny amount of space for apps, making link2sd and the second partition virtually mandatory. The Glide, however, has 2gb internal memory for apps, and the ~3.75gb internal memory that's mounted as /sdcard that you can store apps on with the standard Move to SD build into android, so I can't imagine anyone needing more storage than that for standard apps.
You can always points Titanium Backup to /sdcard/external_sd, my backup folder tends to get pretty big since I keep multiple backups. If she's installing a ton of games that have extra downloads to the sdcard though, you can fill up the internal "sd card" pretty quickly, and there's only a couple of ways to deal with that. She can give you the phone after installing those games and downloading the extra data, and you can manually move the data over to the external SD and create symlinks yourself, which can be tedious.
Alternatively, you can modify the vold.fstab to change the mount points, putting the real external sd as /sdcard and the internal storage as /sdcard/external_sd. There's instructions for this here. The vold.fstab method is what I personally use, as I've got a 32gb sd card and far too many games that want to download 500mb+ each.

Hi and thanks. I just read about that mod. Is it as straightforward as just rewriting that file in rootexplorer? It sounds too easy!
I was gonna format the sd card in the phone but was not sure it would format the internal card and not the external one since I can't seem to get it recognized. I would be in big do do if I erased her stuff!!! It might be a bad card and I'll try an alternate one.

Yep, it's really as easy as snagging the file, editing it, and rewriting it in root explorer (or a shell, I haven't bought root explorer so I tend to do things from the shell). As for formatting in the phone, it should list both an SD card and USB storage, the usb storage is the internal storage, and the sd card is actually the sd card, it *should* have a format option there if the card is good, even if it's not seeing the files on it.

Thank you all!!!!!

Piece of cake!!!!! :highfive: We now have the external sd card (only 8gb for now) mounted instead. Whoever came up with that very clever work around is genius. That's better than apps2sd or link2sd.
Thank you so much to everyone who responded. Between all of you I have Rooted with the kernel on the internal card, and the appinstaller saw the apks when I put them on the internal card. My original 8gb card was bad. It was a cheap one- $5 or $8 dollars. I got 2 and the 2nd one works fine- formatted in my computer and phone saw it immediately. I transferred the stuff from the internal to the external. Did I need to do that? I left it on the internal incase the sd card is removed. Tethering manager is removed- att junk is frozen.
One more question if I may? If another rom is flashed, or I odin back to stock for whatever reason, does this sd card switch stay, or is it overwritten with the new rom? Just need to know what to do if I ever need to reset this phone.
I also added my google account to the market to put my paid apps on her phone but when I signed in to the play store under my account my paid apps did not show as paid. Anyone know why? I worked around it but I was surprised.
Again thanks to such a nice group of people! :highfive: I had a crash course in the captivate glide in 24 hrs. You gave me info here I don't think I could have found with continued searching.

Moving everything that was on the internal memory to the SD card was a good call, since you swapped the mount points everything that stored stuff on the internal memory will now expect that stuff to be on the sd card. There's no need to keep it on the internal memory (you can delete everything there and it'll recreate LOST.DIR) unless you plan on swapping back at any point, in which case you could just copy stuff across before swapping back.
As for flashing another rom, that'll require you edit the vold.fstab again unless the rom has already made that change, which none of our existing roms have.
Personally, I keep the internal memory completely empty as far as daily use things go. CWR will store its backups there, as it mounts the memory independently of the vold.fstab, and all roms/kernels/etc you want to flash can go there, leaving the sd card free for things you actually use.

Bak- thank you so much for all the info. I saved the original file and I will make a copy of the edited mount file in case I need it again. If I ever get her phone back I will clear the internal card since that info is now on the external one.
I wonder how long this captivate glide will hold up with my daughter. She is very hard on her cell phones. Already case #1 broke due to a drop. 2 more are on the way. When I pointed out it could have been the phone broken she said- yeah, I know. I'll keep the case on. :victoryshe hates cases!) Hopefully this phone will get her thru her senior year in college!
Thank you everyone who pitched in to get me the info I needed to get it going. :laugh:

[Q] Many SD cards in 4.2.1

I know that variations of this question have been asked before, and I apologise if it is answered somewhere, but...
I'm running Cyanogen 10.1 and I have four folders containing the entire contents of my SD card; /mnt/sdcard, /sdcard, /storage/sdcard0 and /storage/emulated.I understand that the structure of the memory in 4.2.1 has changed, but I'm fairly sure that each of these folders is actually duplicating all the contents and taking up a lot of memory - I only have 4gb left with no music, movies or photos.
What's the best way to address this issue please?
Thanks

I think all these duplicates are just "symlinks" to the same files because of the multi-user functionality of android 4.2. Therefore I think they are not consuming more storage.
My GNex has a total storage around 13 GB, so if you only have 4 GB left then check the size of the /sdcard/ directory. If it is about 9 GB then the other duplicated directories are just symlinks

When in doubt you could always do an SD card wipe (obviously backing up all important data first) and that should clear everything up. I know you can do that with TWRP, I think you can with CWM, or you can just Lock and then Unlock your bootloader and that will do it for you too.
I had a similar issue after I flashed my first 4.2 ROM without the latest version of TWRP (though mine was definitely not duplicating data as my memory was not extra full), but after a wipe and a flash using the latest version of TWRP I was good to go.

Also do not switch between 4.2 and 4.1 roms as you will get multiple /0 folders and you will have to move everything over and. I believe you can hop between 4.2 ROMs without a problem though. I have had any issues doing that.

so what do you do if you cant see any of your data on the sdcard, but the sdcard still shows the same amount of space used on it?
edit:
nevermind, i found my stuff
it got put in mnt/shell/emulated for some reason

/storage/sdcard0/0/ ???

Help!
I was running FreeGS3, then flashed LiquidSmooth ... now flashed back to FreeGS3 ... and I have this weird '/storage/sdcard0/0/' folder which is my old internal storage folder? Not sure ... sdcard0/ has the directory structure of internal, but it's empty.
It's as if my old internal was 'backed up' to sdcard0/0/, and now there's a new internal storage at sdcard0 ....
WTF??

The same thing happened to me, you just have to move all the files and folders back to the /sdcard0 folder, you can do it with any file explorer or you can do it in your computer. There's nothing to worry about

[Guide][How To] Fix Sdcard / Find backups after cm10.1 Flash!

Same thing happened to me like deja vu after i decided to sample BlackBean 7. Seems to be a CM10/AOKP thing. Went back to my stock rooted TWiz rom anyways. If it isn't broken, don't fix.
I just used Estrongs File explorer to move everything back to where they were and deleted the /0 folder.

Sorry if this is a total noob question but how do I free the 9 gigs that became sdcard/ 0? Im now running free gs3 which im liking a lot more. The major problem I have is my internal sd is now totally full on my 16gig card. The way I figure is if I'm not gonna use cm10 cant I just delete it from the card and get the space back? I have an external card but its only 8gig and was using that for storage of music and etc. Im on a sprint gs3 flashed to metro and am wondering if I reformat the card can I flash gs3 back on or do I need to flash a stock TW? Im not really too concerned about the other files on the internal sd as I figure might as start fresh

If you aren't concerned with the files you can just wipe the internal SD card. However, there is a guide posted a few pages up on how to fix the 0 folder. Wiping the internal SD card will not affect your ROM so you will not need to flash anything.

When I went back to TW for a short time mine deleted fine. Try http://forum.xda-developers.com/showthread.php?t=1646108 and if that doesn't work, backup your data and wipe the internal SD.

This is the cause of the multiple users feature in 4.2. When a new twrp gets implemented that can handle 4.2 properly, this won't happen. Oh well he didn't Google search! It happens, especially with this kinda thing. Try googleing but we'll always be glad to help.

Internal memory folders changed after J.B Kies update?

Hi I have been dealing with this problem for awhile now and still haven't been able to find a fix (without rooting). After I updated JB from Kies when it came out my internal and memory card folders are completely different? Also it says I only have 11.95GB total in my internal memory. The internal memory folder says :sdcard0. And my memory card folder is: extSdCard? I'm not rooted. Does anyone know how to get the folders back to the regular names ext sd ect? Any help would be appreciated, thanks.

That is how it they are formatted now. It's not a mistake or anything being messed up. I guess I'm just used the internal being sdcard0 and ex sd card being extsdcard. I don't use myfiles much. I use root explorer and it can displays it as storage and then inside that folder is extsdcard and sdcard. Or there is a fodler just called sdcard for the internal in the root of the file system.
What problem is it creating, other than just being different than you are used to ?

Yhea, i'm having some trouble too. After the update my extCard is totally mess-up. The folders with the pictures and songs are not recognized, and the Gallery doesn't show hundreds of pictures, but i see if i use a file manager. I've synced all my songs so far, but with the pictures is a mess: seems also the format is not recognized anymore and with Kies i'm not seeing a way for put the pictures in the new folder named "Photo". It's really frustrating.

I cannot use the Apps2sd app anymore. And basically I would just like to be like before the update.
Sent from my SAMSUNG-SGH-I747 using xda premium

i'll try not to rant too hard but Kies and OTA firmware updates are a joke. you are essentially dirty flashing one rom over another with no real clearing of caches, no resetting, no way for all the programs to regroup, rebuild and run on the system hardware/software properly. the thing about dirty flashing is, it sticks well with some devices but generally not with many others. you'll see these types of issues many times among the avid flashers and those that must have the latest release of a developers rom.
i would recommend backing everything up, booting into stock recovery, wiping data/factory reset and wiping cache. if you decide to perform another update via kies in the future, i would do this procedure before AND after the update.
yes, you have to start over when you perform these sorts of actions but you have to ask yourself, are you happy with how your device is performing now (before the update)? is it worth starting over? (it might be if you're going to run on the updated OS for a year or so) and how well do you want it to perform after you install the update?
cheers
EDIT: i just assume everyone accesses recovery and download mode so i didnt post the button combo. recovery is: Volume Up + Home + Power. release just the power button when you get a vibrate.

This is normal for a 16GB SGS3. 16GB is advertised but actual formatted available space is less. 11.95GB is right on par. This is the case for just about all devices that have memory that is writable, including hard drives on a computer.

Any particular reason why you are using Apps2sd? $10 to $20 will land you an external memory card with huge amounts of space (32GB at least). This is plenty to store music, photos, and other misc. files. And even with a ton of apps installed to internal, you still should have ample space left over. There is just no good reason to use Apps2sd on this phone as it has so much internal memory. If this is just to keep you from losing data, then I would suggest rooting and using an app such as Titanium Backup as it makes it super easy to restore apps and the corresponding data after anything that requires a factory reset.

As stated by xBeerDroidx, factory reset from stock recovery. You will have to re-setup your device but it will be a one time frustration for now until the next update.

Actually i did.
After the update, without factory reset, everything was (almost) fine… except a strange malfunction of the Gps (lock signal lost after a while) and sporadic reboot without reason. For the Gps I’ve found here the solution (NV Rebuild), but for the reboot… I wasn’t sure about it. So I decided for a factory reset. After that my ext card, with the ICS paths, was not recognized. So bucked up everything, format the ext card and let Kies sync my files and create all the folders needed from JB: Camera Photo Video for pictures, and media for the music. Now I’m let’s say 90% ready to go… I’m curios to test especially the Gps.

[Q] Free space in internal memory

Hi there
I have a serious problem with my S4 Mini Duos GT-I9192. The problem is that the free internal memory space is wrong. At the moment it's showing about 1GB free space, but I confirmed my installed apps and it's impossible I have 5GB of installed apps. In fact I have about 2.5GB of installed apps, then I shoud have about 3GB of free space.
I made a test, plugged the device in the computer and it shows I really have 1GB free in internal memory, after that I selected all folders into it and get properties, and it shows 2.4GB size. (you can see in attached images)
My question: If the internal memory has 5.39GB and my all files has 2.4GB used space, I should have 2.99GB free space, not just 1GB free!!! Where is this lost space??? I need it, because I want install apps and games, and at now I cant!!
My andriod version is 4.4.2 kitkat (not rooted), manually updated from sammobile, but the problem was the same before update. The original version was 4.2 Jelly Bean.
Best regards for all.

You should look for hidden folders with a dot before the name. I think you probably got a big .thumbnails folder. That's a common problem, try searching on google for solutions.

Did u play heavy games in the past? If you uninstall those games, occasionally their cache/data remain on your device. Go to internal sdcard > Android > Obb and look for any folders that correspond to the apps u used previously. Delete them and see if that solves your problem. I had this problem once in the past when I uninstalled gta3, the com.rockstargames.XXXX folder remained in the obb folder. I had to manually delete that to free up space.
If that does not work, backup everything u got on your internal sd card onto microsd card/usb drive and wipe internal storage via TWRP recovery.
Try what I suggested. hopefully it works. good luck.

Do what he said. you can wipe internal storage from your pc too

Nope, I don't have old data/obb games in device. As you can see in attached screen capture, I selected all existing folders in my device and get properties, it shows I have 2.5 GB used, the refered space is really lost, maybe in some partition which windows does not recognize...

But wipe what? wipe not used files? I can't do this because all files used, I don't have unused files there. Or this wipe process is something which can find the lost space in device?

No what we meant is : You first copy everything from your internal storage to external sd card or usb drive. Then go to TWRP recovery and choose wipe>Advanced Wipe and select internal storage. Then swipe and your internal storage will be cleaned up off everything. Now you can transfer the backup files from that usb drive or ext sd card back to internal storage.Do not format internal storage via windows pc.
Do that only with TWRP recovery. Good luck.

Have you considered that the internal memory is shared?
Infact the internal sdcard is the folder /data/media.
The S4 mini has the /data partition of 5.4 GB.
So if you have 1 Gb free and 2.4 occupied into internal sdcard (/data/media), maybe you have 2 GB occupied into /data? In particular into /data/app e app-asec? (these folders contain the apks of app installed from play store).

Sorry for late reply. You wont lose installed apps but you will lose those photos, videos and any downloads or documents you have on internal storage. That's the reason I said backup/Copy everything on your internal storage to usb drive/external sd card and then format. Later you can move them back to internal storage and reboot.

Ok, guy, thanks for tip, I'll try this

I've got this problem today. Only 800 MB free in internal SD, but when selected all files/folders they only had 1,2 GB!! Where the hell was the remaining GB?
I've entered the recovery and found a backup in the internal SD. Deleted it and recovered the free space!
2 days ago, I've made a backup to the external SD (waiting for the M10 release!), and it really is there, but I don't know how, the backup was made to the internal SD too!
See if you don't have any backup in the internal SD, but you have to go by the recovery.
