[Q] Internal memory vs. external on Honeycomb - Eee Pad Transformer General

I apologize in advance because this topic has probably been beaten to death. I am still a bit confused on how internal and external memory are handled in Honeycomb. A lot of the info I've read applies to non-Honeycomb releases. I'll just start with some basic questions.
1. Is external memory treated differently than internal memory?
2. Can you install apps in either location and expect them to perform/behave the same?
3. Can you place data (docs, music, videos) in either location and expect them to perform/behave the same?
This is all leading to my real concern:
4. If I get a Transformer with 16GB internal and purchase a 32GB micro SD card, will all of that memory be usable without caveats? In other words, can I just install apps or load data in either location without having to worry about things having to be in one place or the other?
Again, I apologize if this a repeat. There just doesn't seem to be a lot of data regarding Honeycomb and external memory. That or it is difficult to find because of the overly common key words used when searching on this topic.
EDIT: If there are any links already explaining this, I will gladly read them and just let this thread die.
Thanks

One important thing to note is that the internal memory is always going to be faster than external. My suggestion is keep apps on internal memory and use the external memory for your pictures, videos, and music.

You can actually get away with smaller apps on a microsd card. Just remember to get a class 6 or higher.

My plan is to have 16 gig internal
32 micro SD in the tablet
32 gig SD in the keyboard dock
LEEDROID DESIRE HD using XDA PREMIUM

This has been a problem since the beginning of android tablets.
Most phones come with an external sdcard when you buy them. So, the internal memory gets mounted at /emmc, and external at /sdcard.
Since tablets do not come with one(and internal is rather large), internal is mounted at /sdcard. Then external would be mounted at /sdcard2, then /sdcard3 i assume for the transformer dock.
The key thing is whether or not the mediaprovider service for android is modified by asus to scan those extra locations. If not, then only media on /sdcard will be recognized.
It looks like the custom xoom kernel work gets around this by mounting /sdcard2 within /sdcard. (/sdcard/sdcard2) This allows the media to be seen on both, but can cause issues with mounting, etc.
I'm not sure how Asus is handling this, but it has been an issue all along.

Actually, I don't think it's a dumb question. I'm still wondering the same thing. What are the implications of installing stuff on the microSD?

[Q] External SD Card/Storage Issues

Hi all i'm fairly new to the xda forums but I just recently had a strange occurrence happen on my S4 that I was hoping someone could help me resolve or at the very least explain it to me.
Ok well I have the sprint galaxy s4 with a 32 gb external SD card if i'm not mistaken. Well I enjoy downloading videos and files to my phone instead of using the internet to watch them because I get bad service where I work. So it's much more convenient to just download them beforehand and watch with no buffering.
Well after awhile of doing this I downloaded androzip file manager so i could rearrange my files so I knew exactly what was on my phone. Well as of yesterday my total space on my device was 16GB and my available space was around 7.2gb. My SD card as i said was about 32 or so and my available space was around 14 to 15GB.
Well I went to try to download a 4 and a half long video in high quality and it all of a sudden said that my memory was full. As far as i knw this video was about 4 gb or so...which should have fit on my device or SD card. Well after finding this unfinished download then deleting it I decided to try to free up some space on my phone to hopefully have more room. Well I googled it and alot of people said an app called SHREDroid was the way to go and that it would completely erase files that I had previously deleted so it wouldnt take up unnecessary space on my phone. Well i used it on my internal and external memory and now my storage looks really funny. My available space on my device is somewhat normal at 7.82 GB. But my SD card is just strange. I havent downloaded anything else and it went from that 14 or 15 GB down to 2.82GB.
How in the world could this have happened. I have nothing new in my external card as far as i know. Can anyone please help me with this?
Sorry for the long post i just wanted to be clear and concise. Please feel free to tell me any details i may have left out
Thanks everyone!
Lots of reports of bad SD cards, so that's a real possibility here.
But what I'd do is backup everything on the SD card to a PC. Then I'd format the SD card (Settings>More>Storage - Scroll to the bottom). Then copy everything back onto the card from the PC and see if that fixes it.
Is your sd card formatted to FAT 32?

Marshmallow Internal SD problem - apps still use phone internal?

I upgraded my 16GB MXPlay to 6.0 and so far everything has been going great, except I'm having issues with Adaptive storage SD. I chose to format as internal, as when given the option it said this will let me store anything on the device including apps on the SD card, but after formatting and installing some apps I've realized the app installation and storage behavior doesn't seem to have changed since 5.1.1.
For example, if I go install some apps from the play store, they still chew up my internal 16GB unless I manually go to settings and move them to SD storage. In addition, this only works on apps that have built-in support for external storage, and it seems like it only moves the .apk, not any associated .obb files. If I keep installing apps and games, it will eventually (quite quickly actually), fill up the 12 GB internal partion and tell me to uninstall some apps, even though I've got barely 5GB of stuff stored on my Micro SD Card.
Literally all that seems to have changed is that /home has moved to external storage, and everything else stays the same. Am I missing something, or is the merged storage option for Marshmellow Moto X Play not all that merged?

It's an Android 6.0 problem. Don't flash your card as internal. Installed apps would always install on internal storage. Just try to move every other thing like songs and images to external timely. Also use a cache cleaner to remove cache.

So it basically doesn't work? Got to say that with a 16gig X Play it was the main reason for an upgrade to 6 (MM). Is this just on the Play or common to all devices running 6?

If at all possible, don't do it. I bought a class 10 UHS 3 microsd card (95MB/s read 45MB/s write). In the Moto it maxes at 55MB/s read and less than 8MB/s write. Compare to the internal @ 110MB/s read and 66MB/s write. The sdcard controller in the phone isn't capable of high speed read/write. You are seriously gimping your performance using a sdcard as internal memory.
I did try it once though, and it saw my internal memory and sdcard as one unit. I strongly recommend not going this route if you can avoid it.

Thanks for info. I have a dual sim French Moto X Play. I'm in the UK but it's possible to buy them off Expansis. I downloaded the Indian Marshmallow 6 OTA off the thread here. Put it on the sd card and the phone picked up the update. Updated last night and all seems to be fine. I decided to give the adaptive storage option a try (before reading your reply) and so far it seems to work ok. My Play is a little tight for onboard storage due to Pioneers Avicsync app which with the maps of Europe gobbles a fair chunk up. Avicsync is a companion app for a Pioneer Avic F-77DAB head unit in my truck. Anyway Android 6 seems to be working very well and no issues. I guess I can reverse the adaptive storage if I need to but for now I'll see how it goes and report back here if there are any issues.

You are wrong mate, the MXP is capable of fast writes on the SD card, it just needs to be the right SD card.

That's strangely low internal read speed. But I do like your sd write speed.
I have had internal read and write speeds all over the place mate, i had an internal write speed of 11MB the other day, never had an internal write over 70MB though.
What is the app for used above for benchmarking sd card?
I had a a SanDisk Ultra 32 GB and my Play was constantly "unexpectedly discounted sd card". A reboot or pull sim tray out and back in again solved it for a while. Then bought a SanDisk Extreme Pro U3 64gb and never had the issue again.
Only problem I've had with adaptive storage was SwiftKey unable to do predictive text - check sd card. I uninstaled and installed again and now working fine.
I say only issue, what I really mean is up until now the only issue. Early days so I'll see how it goes.

THe prob with Swiftkey reappeared - predictive text stopped working. Don't know if it's a MM or adaptive storage problem but suspect the latter. I'm now using Fleksy instead as i've used it in the past. It seems to work fine.

Do you have any sources that say it's an Android 6.0 problem? I have the exact same problem as the OP and it doesn't make sense that this problem occurs. I made a post on android.stackexchange.com about this issue, and even Motorola's official documentation say it should work.

I just am not sure about this but since the adaptive storage came with Android 6 and since then it has started occurring. It's not necessarily a problem. The device decides where to install an app and keep its data in Android 6 at least for moto x play.

It seems the SwiftKey Team works very slow. Ive wrote them (i'm a beta Tester) first in middle December bout the Problem. It helps to change to switch the Keyboard (icon lower right) to default keyboard and back to SWK. Sometimes it works over Weeks without a problem. It's only happens after a device reboot and SD is set to intern/adaptive.
The bad thing is Google Music. It saves the Music on the real Space. Cant understand why Google fix it yet.
Some folks are very angry bout Android 6 portable SD permissions. You cant move apps to SD when the Card is set to portable. It's bad while using a Car Navigation like sygic. Atm you cant put the (big) Mapfiles to the SD. But i know the devs are working on a fix. Sygic said it will work the next beta.
At the Moment i use the adaptive intern Storage... But i hope Google will put some hands on this. It feels it isnt not 100% ready.
There is something wrong with the SD Speed Format-test too. Sometimes it shows "the card is to slow"! When trying to Format the same U3 again and again it works like magic.
Btw: There are many Users (with fast SD cards) in the offic Motorola Forum with this Problem.

On Android 6.0 stock for MXP Spotify saves to Sd when you the Sd card as removable storage. Only thing to to is to give spotify permissions to use the storage - checked and it works.It is very similar to 5.1.1 .Not on Bliss ROM - no matter what i do. Maybe it's something to do with 6.0.1 permissions or rom itself .
Yeah Google music saves too on SD as portable (when set in the Options). But it saves it only on real intern when SD is set to intern. That's a joke! Who wants the Music on a 1-2 gb free intern (like the 8gb moto g3) instead of a 16-128GB intern SD card ?
It feels half finished... There are so many (Google) Apps out there they are not Android 6 adaptive SD ready.
But is indeed nothing new... SD card permissions...
With Android 6.3 its ready. And we see something new with Android 7. (i hope not) grr

If you do a clean install of MM and before you do anything else you set the SD card as internal then any app that can be moved to the SD card will install on it by default. Any app that cant be installed to SD will install on the internal memory as usual.
If you dont do a clean install then you can uninstall apps one by one and as you reinstall them they will install to the SD card, if you just move them to the SD card then when the app updates it will install its self back to the internal memory.
Seems the Swiftkey Devs cant find a solution... https://vip.swiftkey.com/index.php?...d-m-when-moving-sk-to-sd-bug-reported/&page=4
Well I use swiftkey so it'll be a bummer if that doesn't work for me. Hmm.
I've just bought myself a nice shiney new 32gb u3 card to pop in and use as adaptive (bored of running out of space now) (16gb version).
One thing I need to check though, hopefully someone who has used as adaptive will know.
I have an app (bbc good foods) which has data of cookbooks. I got them when they were free but now they charge. The only way I found to back them up was to go into phone memory when hooked to a pc and copy them.
When I've bought new phones I've then copied them back to the right folder.
I know adaptive wont let you see the sd contents from a pc, so would someone be able to confirm whether they can explore their SD / memory with something like ES file explorer when they've done adaptive storage? If so can you, say, download a file from google drive and then move it to a specific location.
Thanks

Adaptive WILL let you see the contents of the *SD* from a PC via USB, just connect and swipe down USB for MTP...well, at least my XT1562 (Sandisk extreme pro) does.

Adoptable Storage on S7 Edge feedback?

Hi
I have seen some posts explaining on how to activate the adoptable storage on the S7/S7E, but never seen any feedback on it. So I have two questions to people who have done that to their S7:
1. Are the performances badly impacted by that 'mod'
2. Is that 'mod' impacted/canceled by Samsung firmware automatic updates?
Many thanks for your help
Phil
Also, can you reverse the process if resents are undesirable?
Sent from my Nexus 6P using Tapatalk
Yes would also like to hear some feed back on this. I'm still undecided
I just started using adoptable storage yesterday. I have a 64GB EVO+ in the phone, and I hated that a lot of the apps can't write on the microsd card because the lack of permission. I don't pull out the sdcard anyways.
Previously, if I move a photo to the microSD card, the file creation dates will all become the moment I moved it instead of the picture taken date and I didn't like that either.
After the adopting of the microSD storage, so far I didn't experience any slowness or lag or random misbehaviors. Taking pictures and reviewing them is still fast as I can remember. I only have 4.8GB out of 64GB occupied on the microSD at the moment. *EDIT: Camera RAW mode crashes all the time. I went back to disabling adoptable storage.
I also want more information on how we can reverse everything if needed, and also whether OTA updates are possible without any problems.

a complete reverse is not hard just time consuming.
1. you have to copy everything you stored so far on your sd card on to computer
2. you delete them from the phone so when you mirgrate everything back to the internal storage the photos and music won't get copied.
3. you go into storage and you mirgrate.
4 you format the sd card as sd card again
P.S. Burst mode on you camera wills top function and will crash the camera app if you convert to adoptable storage. Please spread the word and ask others for a fix or at least a way to disable burst mode. T.T

SD card as Internal? Is it really a good thing to do??

Even though I got 32gb internal and having Samsung 32gb sd card, I selected the option to make 'Sd as Internal' (I thought that in future I'm gonna install huge games and there would be internal memory lack).
But after doing this I can't see my internal Storage and same time Im sensing that my 32gb internal will be not fully used. And I know(as I have some android knowledge) apps in internal(system) will run smoothly than in sd card. And class 10 sd card is good for media not for system contact. Now I have to dump my data(songs&movies) in the same storage where system treating it as 'Internal'. So I may not put huge data in my sd card at where as my internal will be some what unused much.
If you have 32gb internal(this is almost enough to run apps without lags) and 32gb sd(more songs&stuff) I suggest you "Don't make your Sd as Internal".
This is my opinion. What's yours? Am I correct or You want to change my mind throwing some light?
yeah I did the same thing!! 32 gb is enough for apps

I agree. With Android 6 the 'external' storage (microsd card) can no longer be used for moving apps to. It's data storage only. When you have a phone with limited memory (say 8 GB) and want more to store your apps, you can use the SD as internal. This will format (and encrypt?) the SD and replace the internal storage.
As SD is generally slower, I would advice against it. When in a couple of years we're at Android Z and the 32 GB is indeed a bit small, you can opt to go to the 128 GB SD, but until then I would use it for data only. (I have my Titanium and TWRP backups on it, next to some media, nothing more)
32 GB (23~25 usable) is more than enough for apps and few games..and I don't recommend to use SD card as internal..unless your device has only 8gb memory then use a high end SD card..such as Samsung evo+ or pro. (Correct me if I am wrong but I think Google introduced this feature for their low end Android one phones..)
Don't do it , formatting sd card as internal will reduce its performance and also it will be encrypted. So you can't use the data with in it without the same phone you have formated it with. Since g4 plus have 32 gb internal it's totally unnecessary

Mi A1 - new SD card showing double size than it is

Hello,
I just purchased a 64gb micro sd (samsung evo plus) card and inserted it into A1; formatted it as permanent storage, and now it shows as 128gb with half space used with system files. Tried reformatting on the laptop and doing it again in the phone, same result. As far as i can tell, it still works (still 64gb free), but it is annoying as it shows system is using half, so you dont have the real numbers.
I tried googling, found similar problems (a year ago), but no follow up how/if this is resolved. Im running latest 8.1 (november patch).
Any help / ideas?
thanks,
Jaka
After formatting you need to select an SD card as an external memory and then you will have a real state
All of this is done in the seting> memory setting
permanent storage is an extension of internal storage so all correct.
Thanks for clarifying. What is the difference between permanent/removable storage in terms of what the phone can store on it? My phone is full and need the extra space for pictures, cache (streaming apps burn a lot) and, if the card is good enough, apps.
thanks guys, always appreciate the support here on XDA!

I don't' like an SD as an extension of internal memory, it becomes non removable and if it gets corrupted can cause serious problems with apps crashing. It also needs to be as fast as possible.
I would rather have it set as external/removable, you can still store all your media (music photo video etc) on it but it remains removable and the system does not reply on it.
Hey guys, a bit of an update.. Today a got a notification that i am running out of space, a few days after I have inserted a fresh 64 gig card (first post), but now take a look at these screenshots .. In a few days, my whole storage shows as 100% full, just with system files .. ?
I also do not see this extra space in root explorer (where can I?)
Can someone help with this issue? What is going on here?
Cheers,
Jaka
