Galaxy S7 and LG G5 won't treat the memory card as internal storage, despite Marshmallow

Galaxy S7 and LG G5 won't treat the memory card as internal storage, despite Marshmallow

Google's Android 6.0 Marshmallow update may not be waxing drastic changes in the interface of the world's most popular mobile OS, but it doesn't have to. Most manufacturers are slapping their own overlay on it anyway, so Google decided to concentrate on radical changes under the hood, like the Doze battery-sipping mode, the ability to swap even the stock dialer and messaging apps for a third-party one, as well as the so-called "Adaptive Storage."

The Adoptable Storage feature of Marshmallow has the ability to merge the internal memory of a phone with the external storage in the form of a microSD card (if the device has such a memory slot), and treat the resulting cumulative memory as a one total partition. In theory, this would prevent user confusion as to how much exactly free space they have in total on the phone, instead of trying to calculate microSD storage and internal storage separately, or asking themselves what are these things in general.

Now, here comes the surprise - both the Galaxy S7 and LG G5 don't support this Adoptable Storage feature, despite shipping with Marshmallow on board. Thus, they'll treat the microSD card as a separate entity, instead of lumping it together with the internal memory in the storage menu. Here is Samsung's argumentation behind this decision, and we'd wager to say LG could have meant something similar as well:


Samsung decided not to use the Android Marshmallow “adoptable storage” model. We believe that our users want a microSD card to transfer files between their phone and other devices (laptop, tablet, etc), especially the photos and videos they shoot with the camera.

With adoptable storage, first of all the card may be erased the first time it is inserted into the device. This behavior may be unexpected by many users and we don’t want our users to lose their files. Second, once Marshmallow starts using a card for adoptable storage, it cannot be read by other devices, so it loses this ability to be used for file transfer. Adoptable Storage is also primarily targeted towards emerging markets where devices with only 4-8GB of onboard storage are common. We think that our model of using microSD for mass storage is more in-line with our owner’s desires and expectations for how microSD should behave.


After all, Samsung also decided that it is too early to force the obscure USB Type-C connector on the potentially millions of Galaxy S7 and S7 edge buyers, assuming that the negatives outweigh the advantages, at least at this point in time, so it's not surprising that it is not taking all of the options that Google provided with Marshmallow at face value either, what do you think?

can they just make an option for the users to choose?
i;m not bashing, just curious because options is the best option here, right?

Android 6 already gives this choice by default (how you like to use the sd card) but I do understand their reasoning for removing that option entirely. A big downside of using sd cards as adaptive storage is when apps are installed on the sd card part, they tend to slow down dramatically.

that's the problem..people don't want to pay for high speed, quality cards....Samsung would rather do this than let them utilise cheap cards,slow down the devices then bitch about lag
Same with LG

Samsung have sd cards which are expensive, where people won't pay. Stupid, then complain.

You would have to buy SanDisk Extreme Pro for instance, which is UHS-II and on paper comes close to S7 internal memory speeds. But doesn't come close to real life performance.

No phone actually supports UHS-2. Go watch the Note 4 use a 100MB/s card, which if you read the package says with adapter only, and watch the note 4 never get above ~40MB/s

Those are s**t speeds when my 30buck Lumia with internal storage can hit 300-350MB/s.

Until phones can actually use that speed, adaptive storage will make a phone slower and slower. Then you are relying on so many factors of sdcard reliability.

I like that Samsung has choose this path, I do wish they did more of a thing like windows phone but as long as devices ship with 32GB im good.

I have a 80/100 mb speed card and using test app on my moto x play its run at this speed so not my fault if samsung use crappy sd card reader.

Which is still slower than Samsung's UFS 2.0 internal storage speeds. The S6 can hit more than 300MB/sec in sequential read. Let's see your mSD card hit that.

"so not my fault if samsung use crappy sd card reader"
That is one of the stupidest comments i have ever seen so far

So you are saying that samsung is using a crappy sd card reader despite them using UFS 2.0 as internal storage and using finest and greatest component in every department in their flagship .. yeah seems legit

And here's where your hating toward samsung shines ,, you failed to mention LG despite making the same decision about sd cards

And not everyone have the same as your lovely sd card

The problem is that there is 14 retarded thumped you up \:

The new Samsung S7 and LG G5 both support UHS-2

http://bgr.com/2016/02/22/best-galaxy-s7-lg-g5-microsd-cards/

But a 64 GB card will set you back 180 dollars and the 128 GB card will be 300 dollars

Anyone who would compare the speed of internal storage to an sdcard, already has lost the battle.

The controller for an sdcard isnt going to handle data the same as internal storage which is mounted on the PCB and transfers data at the speed of the BUS.

That's liek trying to compare a floppy drive speed to the speed of the HDD/SSD.

A class 10 card is fast enough not to slow a phone down.
SDcards in my usage have not caused any noticeable change in speed. EVER!

If you buy some cheap card, which I have no idea how bad they could be since i dont buy cheap stuff, I will never have to find out.

Techie if you adopt the sd as internal you can still move apps to the onboard memory so basically you need speed put it on the onboard memory thats all.

Still not experienced slower game loading using them from the SD so yeah maybe for bigger file transfert i will see the difference?

Still no reason to remove the features they could just turn it off by default.

I am only comparing speed. Look what happened to encryption, we got plenty of users complaining to the carrier(s) that their phone slowed down and now they want a replacement.

When you hybrid storage, and half data is one place and another another place, then it slows it down. Noticable to the user on a single app? Probably not. Start doing many things...and yes. Then what happens when the sd card fails?

Why would I need to exceed the 80-90MB/s write/read speeds. 4K recording requires 30MB/s write speed. Having card with 200MB/s is a waste of cash.

I think you all need to read this, this will make your ufs be turned off the phone will lag like craphttp://www.androidcentral.com/inside-marshmallow-adoptable-storage

Also sd cards are not made to be used as the main disk in most case it may go wrong and you will note the basic user will use cheap cards

This make a big problem if you use ufs because the speed of the sd card as to be close the the speed of the HD in the phone or you will get the old error your card is to slow, this means, it will happen with all cards, see

Seehttps://source.android.com/devices/storage/adoptable.html

And this part
"
When a user adopts a new storage device, the platform runs a benchmark and compares its performance against internal storage. If the adopted device is significantly slower than internal storage, the platform warns the user about a possibly degraded experience. This benchmark was derived from the actual I/O behavior of popular Android apps. Currently, the AOSP implementation will only warn users beyond a single threshold, but device manufacturers may adapt this fur"

What the hell is that supposed to mean? There is no loyalty when it comes to smartphone purchases, if they don't deliver what you need you buy something else, simple as that.

How can you be a wannabe loyalist? that's probably the stupidest thing I read today.

For me too, glad Samsung is doing it; as for me I'm glad bought a Moto and taking advantage of the feature. Also, people have to understand, when you power up device, it gives you the option how you want to treat the card.

You know certain Samsung TVs which have built in support to record videos to external devices conduct performance tests and determine device as compatible or not.

Samsung could have easily done this and added the Adoptive memory feature.

Samsung surely had a chance to make more incredible phone that no phone released this year would have been able to catch up but they missed the trick, with a number of other features as well.

Its already included in android 6.0 the system test the memory card to make sure its not slow and fast enuf.

Hm the problem is the res test to see if it close to the speed of the included HD, hm and that will be the problem, it's not even going to get close to ufs, it does not get close to Emmc so ther be loads of errors and lag and so on, that and the basic customer will have no idea what they doing

It's clear it a problem with ufs and why lg as not included it also
