[Q] Internal storage

Hi all,
My previous phone was a HTC Buzz (Wildfire). It doesn't have any internal storage, just a pre-installed sd-card.
I got my One V now for 4 weeks, and I just found out it does have internal storage beside the sd-card slot. But what exactly is it?
In Settings --> Storage space it says it got 1 GB of internal storage, of which is 555 MB used by apps. What partition is it they are talking about? In ES File Explorer, I see /mnt/emmc. It is completely empty. Or are they referring to the /data partition (which I, as user, can't really use directly)?
If I want to transfer my own files (music and so on) to the internal storage, in what folder do I need to place it?
Currently a lot of apps are using my sd-card as storage for their settings and caches. Will they use the internal storage for that if I take out my sd-card?
Thank you in advance

Your wildfire could install what....20-40 apps before getting a low storage warning?
Install an SD card, all your apps go to internal, (except app data...ie games) and your SD card is your "user storage".
Unless you install over 200 apps, most of them large, you will never get a low storage warning on the One V and that is a good thing.
When you want to upgrade to a new SD card, just copy the contents over to your new one, install and go........that simple.

Thank you for answering anyway, but my question was about the internal user storage

Please free ur internal memory as free as possible....only keep frequently used apps in it, we have 4GB internal memory of which 1GB is available to us...in es file explorer click on favorites and there will be a phone icon.if u want to paste something not ur internal storage as writable through settings

Ahhh, you mean that 95 or so mb of user storage?
1. No, you cannot move apps there
2. Really, not alot of place for music, some photos sure, just select internal storage in the camera app.
The 95 mb or so HTC left us is basically a joke, if youx have a suitable sd card (16gb ones are twenty bucks or less) I really sugest using that and consider that small space as a buffer if your card is removed and you want to suddenly snap a photo......or whatever.
In the future, when we have s-off and can repartion the nand that tiny space will be irrelevant.

I don't know how much it is. I think it's the /mnt/emmc partition. I thought it was 1 GB.

No problems man, I'll start at the beginning.
Go to settings > storage, you will see:
Internal storage, total space 0.94GB...........it will report apps, and available. The two together should add up.
This is where your apps go
Phone storage, total space 95.23MB.........then available (mine is 95.21MB!!!!)
Storage Card, same total space / available.....this depends on what card you have
This is where app data goes, "user storage" ie. photos, videos, music, email attachments, downloads, etc. It will default to using your SD card if installed. If there is no SD card, or you temporally remove it, it will save stuff to your phone storage.
What partition is it they are talking about? In ES File Explorer, I see /mnt/emmc. It is completely empty. Or are they referring to the /data partition (which I, as user, can't really use directly)?

The "partions" are as listed above. There are some directories that you may not be able to view because you may not have "root access". If you root your phone, you will now have access to view and edit the entire file system (kinda like being an admin on a windows machine). Unless you are an advanced user, this is not really required. Some system files are hidden by default for good reason, change them or move them (or delete them like my Dad on his home computer**#@!) and you can really mess things up in a way you do not realize until later.
If I want to transfer my own files (music and so on) to the internal storage, in what folder do I need to place it?

Like I said before, the "internal storage" is for apps only, your "user storage" on your phone is only 95.23MB. Not enough for music really, maybe some photos (In the camera app itself under camera setting > storage > you can select storage card or phone storage) but....you are limited to the 95.23MB of space.
Currently a lot of apps are using my sd-card as storage for their settings and caches. Will they use the internal storage for that if I take out my sd-card?
Click to expand...
Click to collapse
Yes, but they obviously will not be able to access any data on the card that is no longer in your phone!!!
It is easy to upgrade your SD card from the one that came with the phone. hook a USB cable to your phone, select "disk drive" from the drop down menu, copy the contents all at once onto the new SD card (if hooked upto your computer as well), power down the phone, swap cards and reboot......boom....more storage!!!
I hope that answered your questions, if not we'll have to talk S-off, hboots, nand partioning etc!!!!
Regards.

Thank you for the clear explanation!
I'm running Lloir's CM10 build now. So I have root
If I understand correctly, the 1 GB internal storage is the /data/ partition? And /mnt/emmc is just 95 MB of useless storage? Weird that CWM has got an option to make a Nandroid backup to the internal storage then. Won't fit
I've got a 4 GB SD-card btw

Yup, you've got it right.
The CWM probably has that option for other devices. The HTC desire, by default (similiar to the wildfire), 512MB nand, approx 105MB for the user (apps, user data, everything!). With s-off, we had scripts in which the ext3 partion of the sd card would be read as part of the "internal" storage, so not all was lost.
But, back on topic, yes just nandroid to your sd card.
Cheers man, glad to hear your enjoying your phone.

This is service menu for saving device logs, changing debug level etc. For normal user it has no use, and it does not drain the battery. I am using it a lot at work, as I work at Samsung's R&D, but You will have no use of it. Keep it as it is.

Ok, thx for reply

No use ? Even for clearing logs and thus freeing some internal storage ?

Free Up Internal Storage !! wow !! *resolves Insufficient Storage Space Error**
It freed up my internal storage by 1.3 GB.
I am using galaxy S2 / GT-I9000 , my apps was not installing bcz it was showing i had only 198 MB/2 GB free...i used all kind of cache cleaners and everything but to no avail.
Then i used *#9900# and cleared dump...now it says 1.4/2.0 GB left and i can install as many apps i want.
This is also a cure for "Insufficient Storage Space" while installing apps.
Not sure if it works only for samsung
But it worked for me

The code doesn't work for my Note 2, but clearing some logs would be nice, since the devices have too little internal storage (Why? It's so frustrating, having 64Gb of external card, while still getting errors during install/update of apps!)
Any other way to clear these logs?

I 'm using the external 2 internal app in my razr d1 xt918 kitkat 4.4.2. In the 'internal mounting' i'd wrote ' /storage/sdcard1'; in the 'external mounting' i'd wrote '/storage/emulated/0'; after that push the ' view different devices', go until the '/dev/fuse', click it. Now you back to the initial menu and click in the 'external internal' and in the 'at boot'... ready! Now I have three storage mounted: internal sd, emulated and sdcard1... everyone haves the same memory value of the micro sd.

out of space warning

i have 1 gb on phone memory but i am taking this warning.
"out of space. x could not be installed. free up some space and try again."
mostly in low size apps.but not fully. i dont know. some apps gives this error some dont. i used lucky patcher and fixed from it but nothing changed.

[update] you posted a reply before I did, good to know it's solved.
Ah, just that I noted a similar thing with Link2SD and by changing the Link2SD settings to:
Settings -> Install Location -> Automatic [x]
I was back in business without any low storage space problems.
You may like to have a look at Link2SD and see if installing this application is right for you.
Out of interest what does settings -> storage say is currently available on Internal Storage
There are many cached files on the Internal storage and maybe some have a difference between allocated size and used size.
If you're only seeing the 'used' internal storage size reported, the true available(unallocated) amount of space may be a lot less if new/updated apps are looking for space not already allocated.
These are just some of my ideas and not know to be true for the XPERIA M at this time.
I have used SD Maid - System Cleaning Tool in the past and it's pretty good (all be it a bit quirky) at identifying a range of system file that can be optimised/deleted.
It knows about camera cached thumb files too.
On the XPERIA M in the Settings -> Storage there is an option to 'move' all pictures, music and video files from internal storage to your SD card too.

Thanks man i will check them too.

insufficient Internal storage

Hello..
I have htc desire 816 with 8gb of internal storage ....when i bought it,it had about 4gb free of that storage.....which is quite normal.
After buying it, I updated to lollipop 5.1 then i got it rooted......
Lately i've noticed the insufficient internal sotrage,so I've uninsalled ALL the apps and games from internal and external memory,however,that only freed up about 2 gb of the intrrnal storage ....so what is taking all that space despite there is No apps ....I know that the system files are taking some space....but those files only took 4gb when i bought the phone
Now i don't have any apps ,However, there is only free 1.8gb
I tried using clean master,but it only cleaned about 300mb of junks and cache

This is strictly a personal opinion but you should lose Clean Master and anything else made by Cheetah Mobile.
As for your storage issues... You state you've rooted. Have you done a backup? If so, are you sure your recovery is saving backups to the external storage?

Had the same issue. The firmware is in it's own partition with room for updates but some of those files fill up your internal storage as well, they did for me when I updated so the solutions are either use a root file explorer or Titanium Backup app to move some user apps to system apps , use the forum here in XDA for altering your SElinux permissions and enable write permissions to your system partition(WP.MOD_KO) so that you can use Link2SD app to move your user apps to your external SD card or pay to obtain full S off using the Sunshine app and have those permissions plus more enabled at the system level so that you can also use Link2SD app to move user apps to the external SD card.
The last 2 methods are the most used and also require you to reformat your external SD card into 2 partitions using EaseUS PARTITION MANAGER on a P.C. Instructions for doing this are easy and available on Youtube and Google if you want to read them instead. These are really the only ways to help your storage issue other than just not using very many apps. I chose the full S off method and Link2SD but the other works it just alters your SElinux permissions and has to be removed to do stock updates whereas S off doesn't affect stock updates. Only system file changes do like the mod I described.
I also echo the previous posters thoughts on Cleanmaster and most all "task killing" apps. Android has built in RAM management that does a good job on its own of managing memory and there is the on screen square button on the right that shows you open apps and tabs and allows you to quickly close them all out. You'd be better off regulating Wavelocks using Amplify app and Greenify to freeze apps from staying on . Root required and there are paid version but the basics are free in both apps.
I had a brain f**t and misread that you've uninstalled "all" of your apps so the previous poster might be onto something if you've done any TWRP nandroid backups to internal instead of micro storage. They can take up to 2 to 4 gbs just on their own even with compression enabled. If you haven't and even if you have my previous info and advice is still accurate for improved storage space.

Yeah mine says 550 mb total in thumb data but it is not pictures from my camera like the other few kbs are. Can't open it so I wonder if it's some sort of cache for something else. Don't know all the ins and outs of the Android file structure but I do know that when I started flashing custom roms,CM in particular, my internal storage went up due to the lack of bloatware coming from my stock Rom. Good to know this though. Not going to delete it though for now till I find out what it is.

Some Apps, like WhatsApp save pics in .thumbnails to work smooth, i think.
You can delete them, but they will create themselves at the next boot again, i also tried to write an init.d script which deletes them at boot, but it doesnt work.
Also if you create a file ".thumbnails" which isnt writable, the system doesnt give you the space
Ive read something about creating this file before first boot after flashing so it works, but i havent tried it...
Damn thumbnails
Sorry if my english is horrible ^^

Your English is perfectly fine. Better even than some to whom English is their "first" language. Thanks for that breakdown and I bet that's what it is. I forgot about the apps storing their stock images in your phone. I used to love using the app called Pocket until I found that it stores all the saved links and images directly on your phone. I saved almost a full gb by deleting it finally. Great app other than that and if I had a device with more storage I'd still have it on my phone instead of just my computer. This is all why it pays to be curious about your own phone storage and learn how to navigate a good root file explorer.

[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.

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.....
