Ram Management - Samsung Galaxy S8 Questions and Answers

Hello!
Lately I am very unhappy with the performance of my S8 and today I was bored and did a bit of a speed test between the S8 exynos and my backup device, the good old HTC M8.
When opening apps,the S8 was a bit faster,but when it came to ram management the M8 with 2gb less RAM managed to keep all the apps in the background and remain smooth while the s8 had to reload 6 of the 9 apps and the phone was clearly stuttering.
Someone else experiencing this issue?

[Q] Opinion needed from S5 and S4 users

i have a S4 now and i want to upgrade to s5 but i am afraid of RAM capacity.
even if they both have 2GB S5 has much less free ram on a fresh start (arround 400mb)(while s4 has arround 1100mb).
I had the same problem when upgrading from s2 to s3. Multitasking was horrible, everytime i wanted to reopen an app it would reload everything and not take me back where i left. even Facebook messenger heads would close because of low ram.
My question: is 2GB or RAM enough for you? do you use a lot of apps at the same time?
Does any s4 user feel a different when upgrading to s5?
thank you in advance

Galaxy S6 vs. iPhone 6 vs. HTC One M9 real life speed test

Watch until the end!

TouchWiz eats too much RAM requiring each apps to reload. Check out the Free RAM available on the S6 threads and you'll see that it barely has free RAM.
according to this, i should have gotten a iphone 6 (something that falls in between). Guess I'll have to chunk this M9 DevEd in the garbage and learn to like IOS ?

Free ram is wasted ram. I highly doubt touchwiz is using so much memory it's causing other apps to be killed. It's more likely that Samsung got a little happy with killing apps in the background trying to save battery.
Probably will be fixed in a update...
Hoping HTC is able to optimize for the s810 as well, as it seems very poorly optimized atm

Well, if the RAM is taken over by just the UI and System, it's a wasted RAM. How come M9 usually has over 1 GB of Free RAM yet it can load all of the apps that are cached in RAM while S6 has about 200 MB Free yet it reloads apps EVEN IF those are supposed to be CACHED. I suspect a memory bloat where there's little RAM available for APPS to cache properly.
all that this video show is the following:
- persistent software issues on the Samsungs like hangs and needless killing apps out of RAM
- the s810 / DDR4 / 3GB combo on the M9 quality software really shines when it comes to multitasking
- Apple's high IPC from just two cores should be a big a lesson to anyone building Android SoCs

4GB RAM is it enough?

Hello! I am thinking about changing my poor old Oneplus One for this beast. But I am worried about the RAM quantity. At this moment I have 3GB RAM and I don't know if 4 will be enough.
Isn't TouchWiz 4GB = 3GB AOSP debloated?

Of course it is enough + you won't keep your phone for more than 2-3 years. TouchWiz got better, but not perfect. My phone still has ~1.5 GB of Ram left. My notebook has 4 GB Ram with fast SSD, don't see any slowdowns on Win 10 Pro.
With the poor ram management 2.5 GB is enough because at no point it uses more than that on our phones. I have apps refreshing when I come back but only half of ram is being used.
in my opinion, 4gb is not enough..... For that kind of high-end phone, samsung should have put 6Go at least into it. I'm talking about ram managment which is pretty bad in android and when you take a look at speedtests (even if this is not reflecting real daily uses) you can see than phone with 6go of ram are able to keep many apps in memory way better than the s8. When you start to run heavy apps or games, the built-in memory killer kills a lots of background app and then when you need to switch back into an other recent app, the phone almost reload it :'( That's frustrating
4GB Ram is enough. More RAM means more apps running in background which means more battery consumption. So 4GB looks a good balance here atleast for S8 which has only 3000 mah battery.
i don't think so excuse me. Of course, more ram maybe means more battery consumption but i prefer that and kill apps runing in background manually to keep battery life rather than the os kills things that i still need :/
When you have 4gb then 4gb isnt enough, when you have 6gb then 6gb isn't enough... its never enough.
4GB is enough for most any smartphone. I also have a OnePlus 3 with 6GB ram and while it can keep more programs running in the background, it never totally accesses the entire 6GB ram. Read this XDA article on RAM: https://www.xda-developers.com/the-ram-conundrum-do-we-really-need-6gb-ram-on-android/
4 is enough, and please after buying it do not ask about why just a little of it is free! The ram is for holding services and apps in background so cpu should not work again to bring them up, if it's filled do not be sad, it's natural.

Why should you want to keep many apps in memory? The S8 loads them so quick anyway.
Who needs in real day use to keep in memory 5-6 games plus 6-7 apps ? That's what they are doing in speed test , but in every day use it's not need for 6-8 GB ram in this moment. In my opinion for the manufacturer it's simpler to put more ram in a phone instead a better over all optimization.

Have to say 4gb Ram is NOT enough!

I've owned the One Plus 5 the 8gb sys ram version and apps stay in memory for super quick access, the apps on my S8 plus constantly close and have to reload them back in memory, yes I've disabled close apps when idle, this phone is still randomly closing apps when it runs out of memory, whoever says a phone does not need more than 4gm ram is wrong, try the OP5.
4gb is not enough because of touchwiz ui. Oneplus has no skin. Its near stock ui. Thats why oneplus os takes less ram than touchwiz os.

No, it has 1.5x to 2x the ram, that's why ...
Samsung galaxy S8/8+ = 4gb RAM, Oneplus5 = 6gb/8gb RAM.
Not too hard to see why it handles apps better...
Touchwiz probably doesn't help any but the extra RAM is the real reason...
Why do you think the Note 8 comes with 6gb RAM?

And the fact it has twice the amount of ram helps also, was waiting for the pixel 2 but if they're are only going to use 4gm ram i'm not bothering.

Yep I agree, i'm really disappointed Samsung only used 4gb, I've just had to reload the android messages app twice in the last 10 mins! this did not happen on my mate 9 or the OP5, it's actually getting tiresome now seeing all the social apps have to reload back into ram, I really do miss the OP5 for that, I've turned off all closing apps when they are inactive for useless crap but still basic stuff is still closing down, play store, email, Instagram, android messages etc.
There is an option to lock apps to RAM if you dont want it having closed.
@Akram. How do you lock apps in RAM?

Thanks I'll give that a go however I've tried these things before on other phones and they never worked.

That's a hell lot of phones you used buddy!
Btw, what made you buy S8+ after OP5?
Lock apps is a good option as the basic tw settings don't allow lots of apps to be in RAM. That's why the idle battery life is the best on S series.

The OP5 had all sorts of issues, the main 1 for me was the jelly scrolling and camera not that great, but my mate 9 broke otherwise i was waiting for the pixel 2 which i may still get yet depending on how much they put in it, if it's like the rumours say 4gb then I'm not buying anything again unless it a minimum of 6gb ram, these social apps chew ram up and 4gb these days is useless!

LOL, only 2 phones. In the last 6 - 12 months I have bought -
1. Axon 7 - 6gb ram 128gb rom - great phone but took too long to unlock and I got bored with it.
2. ASUS Zenfone 3 Deluxe - 6gb ram 256gb rom - brilliant hardware, stock rom OK but a few bugs - unfortunately ASUS didn't release unlock tool until too late killing off developement.
3. Nokia 6 - 4gb ram 64gb rom - OK for a budget phone but again no bootloader unlock.... Bored now, NEXT...
4. One+5 - 8gb ram 128gb rom - really like it but running out of storage- at least the others I can put in an sd card...
5. Samsung Galaxy S8+ -4gb ram 64gb rom - got a bit cheaper so was in, still exploring stock rom so not rooted yet.
6. Samsung Galaxy Note 8 - 6gb ram 64gb rom - on pre-order... Awaiting judgement. Unfortunately living here in Oz it looks like I won't be getting my shiny new toy until mid October... Got grey import (love the description that it's Oz stock but then these things tend to come with an overseas plug with a cheap sh!tty plug adaptor) but it was approx. $300Aud cheaper than the ones avalable in shops here...
Also waiting for my Jellyphone pro, a really small android phone I got on Indigogo... So sue me, I'm a sucker for computers and phones....
Out of all these phones the Galaxy S8+ is pretty laggy in comparison, even the Nokia 6 is pretty decent in comparison. Hopefully the Note 8 is a bit faster and the extra RAM will push it back onto the top of the heap...
4gb is useless? Lol. Ok... Whatever you say...

Yeah, I'm not really getting this assertion either. RAM is really only one component that would impact lag. The first of which would be the kernel and how CPU governor settings are applied. I consider myself a fairly heavy user, and I'm not at all upset by the response time of this phone.
Yes 4gb ram is not enough for the advancing technology of smartphones. 6gb or more is recommended.

Wow didn't know AUD are cheaper then INR
But you get them as locked and cheaper so it's fine.
Anyways, enjoy till you get bored
Have fun! Jio jee bharke

Nope, only if you get carrier specific phones will they be (sometimes) locked. Generally this is for cheap prepaid plan phones....
And the Aus dollar isn't cheaper... That's why we have grey imports....
Did anyone who has his phone rooted, try SWAP memory? Making a 2gb partition on the internal storage or even a good quality SD card.
I remember this was a thing few years ago, but everybody just forgot about it.
I agree that 4gb is not enough. Really notice the phone e slows down when downloading in the background

Im fine, everything runs smooth. You prolly have to be a heavy user.
Who ever asked why Note8 has 6gb, thats an odd question to ask. After the last years N7 i dont think they wanted to take any chance and tried their best to give as much as they could. Although i still passed on it, 1500$ no thank you. Id rather walk around with my laptop.

Disable Ram Expansion for a boost in performance

Since android 13 upgrade (wasn't amazing before but certainly was much worse since 13) i've been getting really inconsistent gaming performance.
But not in a way that dipped the FPS -- as system status in games was showing good fps but the game felt jittery / laggy and overall very inconsistent.
Been driving me nuts to the point where i'd almost stopped gaming on it because it was so disappointing. Was going to send my phone into Oppo for warranty claim it was that bad.
Decided to try and be a little more analytical about it and look at the individual element scores on antutu and i saw my RAM performance was pretty bad.
Played with a few settings but nothing seemed to do much until i remember about Ram expansion (using storage as back-fill ram) and tried turning that off (reboot after).
Well, my antutu score has gone from 720k to 806k in normal mode and ~830k in performance mode (since antutu isn't recognised as a game to automatically do that)
Games are now totally smooth again, no lag. It's almost like a new phone.
My thoughts are that the android implementation of this either doesn't properly keep active high-demand stuff from swapping into this expanded ram or that android just doesn't handle the scheduling of this properly.
Either way -- for me its way more valuable turned off for overall performance and stability.
Did the same already some time ago, can not understand why in the first place. that a phone with this huge amount of ram already factory installed, would need another 3 GB of ram.

Technically it doesn't i guess... maybe for a ram constrained phone ... but then if it's costing performance cos of a bad implementation then it's a lose-lose position.
My phone is noticeably more consistent on performance with this feature disabled.
