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:

How the M8 handles an SD card as internal Storage.

This is a completely 'unsexy' issue I have - but is driving me nuts, and I can't seem to find the answer anywhere else (which is causing me to doubt my own sanity).
My reason for using the internal rather than external is that whilst external works on some apps where you can explicitly point to the SD, there are enough where it doesn't (spotify), and I was hoping OS level settings would resolve my issues.
Enough preamble.
Marshmallow is supposed to handle SD cards properly, and I have two marshmallow devices with SD cards I've formatted as internal storage.
First up, my nVidia shield K1 where I understand it.
I put the SD card in, format it to the device and end up with two items displayed under settings->storage - internal and SD memory.
When I install an app it initially goes internal, but I can move it move it to SD, and when I launch it the app it can only see the storage it's been installed on.
i.e. podcast, plex, spotify I anticipate to use a chunk of space that doesn't have to be fast. So I install them, move to the SD, load the app, they report 128GB of space and happily use it.
All great. Whole kaboodle stays on the SD.
On my M8 though, it completely broken - except I can't find anybody else ripping out their hair - hence the questioning of my own sanity.
I add the SD and format as internal. I choose the apps I consider to be "high-capacity" and move them on my SD. The app installs there - just when it downloads anything, it dumps it to the internal storage still.
e.g. I've got a 20Mb podcast app I've moved to my SD. Within the app I've selected internal storage (being the only option) - but when triggering the download it's put all the MP3s on my internal storage and my phone is bleating that is has no free space and bad things are about to happen.
AFAIK the Marshmallow update to my M8 is completely broken, and the simplest thing I can do is just mount my SD externally and use hope apps requiring storage allow me to select it.
Just can't believe it's that broken and hoping somebody can point me towards how I can resolve it.

I have the same, insanity inducing problem and hope some has found a solution since this post. I hope this reopens the tread and some one can help me out.

Hmm was looking at getting a m8 as well but if adaptable storage is broken the phone won't be of any use to me. I hope we can find answers and solutions.

Problems with Storage.

Hi, my name is Julian, I am a newbie and I've got two big problems with the Galaxy J5(I think 2016) with 8GB internal and a 32GB SD Card, Stock Gapps and Lineage Os:
Internal Storage Issue
The Phone constantly says “Not enough Storage”, although there are NO extra Apps installed, except Whatsapp, and he has no personal Data(Images, movies, etc....)
BUT when I look in the Storage option in the Settings, the Calculation is not correct. It says : 3Gb for Android, 1,5GB for Apps and maybe 0,5Gb for Data, but the rest is not showing up.
SD Card to Internal Issue
So because of the 1. Issue, we decided to format the SD Card as an internal Storage. We searched up where this Option is to find and then we tried it. During the process it told us that we would free up about 2Gb of the Internal when moving stuff to the new formatted SD, so we did it, but after all There is no Extra Storage, and we are still not able to install apps from Google Play to the SD Card.(And it also says that 16GB of the SD Card are for the Android System, even if there are only 2 small Files or so).
I would be really thankful if you could try to fix our problems, because we can't go back to Stock because the Backup was broken and the copy from the PC doesn't even show up in TWRP(nor with the Backup function, neither with the File explorer function).

Storage is a general problem. Not device specific.
It is no good idea to use stock GApps. A minimal gapps is enough. You can install Google apps from play store.
WhatsApp doesn't use adapted storage AFAIK. Especially videos use much memory. Delete them all.

Does someone try the adoptable storage since the last Nokia 6.1 update?

Hello,
Normally, in a perfect world, adoptable storage should allow to enhance memory thank to the sd card.
Anyone who tried to use the adoptable storage with the Nokia 6.1 encountered the problem of corrupt datas.
See
https://forum.xda-developers.com/nokia-6-2018/how-to/adoptable-storage-available-pie-update-t3873841
Does someone enough brave already try again to activate this adoptable storage?
Thanks you

yes, I retried it last week (with latest official patch applied).
I migrated > 10GB of data. Afterwards I checked 'DCIM' and 'Download'. All files got totally corrupted (looks like every byte different).
It seems that newly created files were not corrupted. (Was just a fast check with 2-3 pictures)
I migrated back and removed SD card. Files still corrupted. During the last test in ~2019 I figured out that the files some when magically got fixed again some time after migrating back. Hope this happens again this time...
Maybe it also just needs some time after migrating to reencrypt the files for the SD card?
Does anybody know more about the internal processes during and after migration?

Hi, I didn't try the above method, but I used adb commands to format the SD-Card as internal. It basically worked and I am able to run the apps that I migrated to the external card.
HOWEVER:
1. The external card and it's files are completely invisible to any file-system-apps. So I can't see the data.
2. Apps that require some kind of login never keep that login. If you close the app and start it again, you need to login again. This seems to indicated that the apps have been migrated, but are unable to actually use the external space to save new files.
Does anyone think that rooting the device would help?
Cheers,
Calon

my experience with adaptable storage was the same as krisha2k's. all migrated user data I had appeared to become corrupted, and most apps that I moved to the sd card either couldn't save any app data (game saves/logins) or even lost functionality (Snapchat friends list disappeared). some really old and ancient apps that I moved to adoptable storage kept their saves etc (ice cream jump, Neko atsume).
I also found that games with in-app downloads would save their download to the internal storage, as well as external when the app appeared to be stored on the external only.
most apps are broken because of newer android changes that protect external storage write access (and i think read too). I'm not an expert in that though. just speculation
in the end, I just did a factory reset and I've settled with using the sd card as portable storage and storing large files on there (4k video from camera etc).
its a shame because it was a spare 128GB card I had lying around, and I would have liked to have some bigger apps installed, but it doesn't matter too much. but I guess that's just how things are now.
i personally wouldn't recommend doing it. you have potentially everything to loose if you accidentally migrate all your internal data, and what seems to be absolutely nothing to gain.

[Method] Merging SD Card with Internal Storage

This post documents a method of enabling Adoptable Storage with adb commands on sony phones where previously similar solutions seem hard to find. Please link similar methods if they exist somewhere else, I am curious to read.
Personal success on SO-02K (NTT DoCoMo XZ1c ) fw version 47.2.B.5.38 Android Pie, 128G A2 card.
The method results in a fraction of the microSD Card being recognised by the system to be able to transfer apps to, and another fraction where the sd card remains external storage.
The Stock Camera will only be able to save to the mentioned external storage partition after this process, and it will fail to save to internal storage.
Some apps may not work when transferred to the sd card and have to stay in onboard storage.
Premise
I carried out the process with a freshly flashed phone, with a minimal amount of apps present in the system. I cannot guarantee same success with an almost-full phone, although in principle it should be the same. If anyone has success on a more full system please let me and others know.
ADB Debugging should be turned on in developer options and authorization of PC given in advance; root or bl unlock not necessary.
SD Card will be WIPED in the process. For your data's safety do backup everything on your phone, both internal memory and external memory before proceeding! Don't yell at me if in the end it'll have to be restored.
Process
adb shell
sm list-disks this should return two integers such as 179,0
sm partition disk:179,0 mixed xx where the 179,0 should be your result in step 2 and xx be the amount of space reserved for /sdcard ; wait until command finishes. For the mixed xx see Miscellaneous#2 for explanation. Please also reply if you know the command to revert the changes made in this step, because I'd expect it be useful in the future and I don't know what it is.
Turn on force allow apps on external in bottom of developer settings if haven't done so.
Open camera app, click on OK until warnings go away, then set save directory in SD Card. Test if it saves successfully, if not, see Miscellaneous#1.
Reboot, then try moving some apps to your sd card! Some core function apps are not movable; that is to be expected.
Miscellaneous
If your camera won't allow you to open up settings (keeps saying cannot save), then you have run into a problem I have never seen before. If you can go into camera settings but the SD Card option is greyed out, that means either you have not reserved enough space in mixed xx or the command may have gone wrong. Or the card may not be in perfect condition for Adoptable Storage. You can unplug the sd card to see if the camera works fine after that, but I haven't tried that. If anyone knows the corresponding command to revert the changes made in Process#3, please let everyone know!
The mixed xx part allows a part of the sd card to remain.... an sd card. xx% of the space in your card will be recognised as external(portable) storage by your phone, and is readable by a PC. This portion will be the place where your future photos and videos are saved in, as the camera will fail saving to internal space. Thus you may want to use the fastest card you have and set xx based on your use patterns. The other part, the (100-xx) % of space is recognised by the phone as internal storage that it can put apps in, although some apps (especially some games) will still save assets in the phone's on board storage no matter where you move the main app.

Thanks for sharing this but in my experience it does not work. I followed the guide and It looks like it worked, however now I don't understand how to move the apps away from the internal memory to exploit the new storage space provided by the SD "internal" memory... each time I try to move an app I get a "not enough memory" error message although there are about 64Gb free, no matter what app I try moving. I also noticed that deleting an app from the phone and then re-installing the app in the phone will finally install it in the SD but several apps I tried didn't work any more once re-installed in the SD storage.

Hi and Merry Christmas!
I do get system warnings saying the phone is full while it isn't; it seems that Android freaks out a little trying to gather disk usage info when the SD card is merged with internal space. However I can move most non-system-apps.
Did you move the app with the (Press&Hold App Icon)->App Info ->Storage->Change function? I found I didn't include this part in the original writing and might have been a source of confusion. Assuming it was done in App Info, could you tell me what apps don't work, and perhaps I can try on my phone. I also wonder how much storage did you allocate to each of the two partitions on the SD card.
Another potential source of error is the card itself, in some cases, the card may have bad blocks that Android doesn't correct for and cause read problems, as my SD card now begins to show. Sometimes I wake up to see my home screen devoid of apps, and I have to reinsert and restart the phone multiple times before the SD card gets recognized by the phone again.

it doesn't seem the card, since the remaining 64Gb left for external storage, that is where the camera app is saving photos and videos and some other apps save data, still works fine.

Here it is the screenshot of how Android now sees the storage configuration (android settings > storage) after I performed the procedure described above for configuring adoptable storage (writings are in Italian but I think it should be easy to understand).

mine looks the same. I don't know what to suggest. I'll look around on other forums to see if people have the same problem.
This post is re-written from original post in Chinese which in turn is adapted from a lost post on gfan.com.
It also turns out that googling sm partition would give a lot of information most dated back to android 6.

I've been looking around as well, but was able to find only people reporting failures in enabling odoptable storage on Sony devices. However, one difference between your phone and mine is fw version: mine has 47.2.A.11.228 (no brand) - don't know if this can make any real difference.
By the way, I'm wondering whether it could be possibile to install a rarely-used app in the internal memory, then "park" the app in the SD card's external memory by moving its files, then eventually move it back to internal memory only in the case you need opening that app. If it works, it could be a trick for keeping all the apps you want "freezed" in the phone, by taking the usually unused apps in the external memory, then moving one of them in the internal memory only in the rare circumstance you need using it. Then moving it back to the external memory if you think you won't use it any more for a long period. Obviously one could simply uninstall and reinstall those rarely-used apps on occurrence, but that would take more time, consume data traffic and lose the app existing data, so I think that >IF< this kind of trick could be feasible, I'd go for it.

I've been looking around as well, but was able to find only people reporting failures in enabling odoptable storage on Sony devices. However, one difference between your phone and mine is fw version: mine has 47.2.A.11.228 (no brand) - don't know if this can make any real difference.
By the way, I'm wondering whether it could be possibile to install a rarely-used app in the internal memory, then "park" the app in the SD card's external memory by moving its files, then eventually move it back to internal memory only in the case you need opening that app. If it works, it could be a trick for keeping all the apps you want "freezed" in the phone, by taking the usually unused apps in the external memory, then moving one of them in the internal memory only in the rare circumstance you need using it. Then moving it back to the external memory if you think you won't use it any more for a long period.

Striking news in the new year-- my sd doesn't work now. Yesterday I checked everything worked, but now no apps installed on my sd card open. using sm list-volumes shows both internal and portable partitions on the SD are mounted, but the apps still refuse to open.
The card looks like it's corrupted, now the two partitions can't even be recognized with my card reader, I guess I'm screwed.

at my asus max m2 .... working, camera, i can move app to sd card and they still works
butttt the only thing is at settings/storage/ information; it shows numbers that dont are correct and a option "to forget sd card " ?!?!?
well i don't know.....
