I'll try and make it easier to understand. What he is saying is that right now we have something called zswap. This is different from normal swap. Normal swap is for when your device runs out of space in ram. In this even it "swaps" things stored in ram to your hard drive or flash drive. This frees up ram space but the problem is when you try to access something that's in the swap space on Your hard drive its very slow at least relative to ram because ram is ridiculously fast. What zswap does is instead of swapping to your drive/flash it instead cuts out a an area of your ram. Then when it needs to swap. It basically does the equivalent of putting the stuff into a zip file and sticking it into the reserved area. The advantage of this is that by compressing it and putting it into ram we can still keep the stuff in ram but it takes up a lot less room. The downside is that putting things in and pulling things out require you to essentially unzip and rezip it each time. Which slows things down and uses CPU cycles. Currently we use an algorithm called lzo to do this. Its pretty fast and compresses them down a good amount. He wants to try LZ4 which is much much faster, meaning we can pull things out and put things in at many times the speed, however it compresses them less so they take up more room when stored. Hope this makes a little more sense! :)
[Galaxy S6 General] LGSilva:
This is nice. May I suggest to take this to the original development forum on its own thread? That way it will be easy to follow any progress :good:
[Galaxy S6 General] Globalrebel:
Makes complete sense now. It is almost like the hard drive/ssd you can buy. (in a VERY HIGH LEVEL WAY) I'm amazed that compressing and uncompressing files continuously is faster then accessing the uncompressed files on samsung's new memory. I thought that was a VERY large push for them on this phone? The memory was supposed to be soo much faster in conjunction with the flash storage.

In any case, I really do appreciate the information/overview. I truly hope some good comes out of this as I notice constant re-loads and sometimes even re-draw on my launcher. I haven't had music drop out yet, but I'm sure its just a matter of time.
[Galaxy S6 General] monkeypaws:
I ended up going back to my nexus 6. Have to keep reminding myself that any fixes will get to my phone quicker than the s6 and if I have to wait 6+ months for a fix and google has released a few maintenance updates I'll never be up to date. It was an awesome phone but quick updates are my priority. Sorry for ot just replying to my original comment earlier
[Galaxy S6 General] Xileforce:
oh the UFS file system is ridiculously fast for sure and obviously speeds up swap if it has to swap to the flash. But the worlds fastest ssd compared to even a slow stick of ram will get killed. Ram is ridiculously fast. As in the bandwidth on ram is measured in gb/s and the bandwidth on ssds is measured in mb/s its not even fair really :( heres something i just read on a website "SSDs can deliver up to about 654MB/s while 1333MHz DDR3 in dual-channel mode can deliver up to 21.3GB/s" and we have ddr5 ram in this thing so that number is even more skewed towards the ram. Plus you have to consider that ram is literally designed for constantly moving things in and out very very quickly. frequent reads and writes are bad for the longevity of ssds especially. I was blown away when i learned how much faster ram is than an ssd years ago. Thats why some people create "ramdisks" on their pcs which is basically a hard drive that is actually in the ram so its super super fast. problem with ram is everything inside ram gets wiped when the power goes off....
[Galaxy S6 General] LNJ:
Are you sure it's DDR5?

I thought it was DDR4 for the RAMand GDDR5 for the graphics RAM.

Regardless faster than the DDR3 on the Snapdragon 810.
[Galaxy S6 General] Globalrebel:
This is awesome! Thanks EVERYONE for all the information and well thought out descriptions. I'm still crossing my fingers something can be done about this usage problem.
[Galaxy S6 General] Xileforce:
Indeed you are correct! Sorry I was just going off of memory it is DDR4 running at 1552mhz according to anandtech. No idea where I got ddr5 into my head lol
[Galaxy S6 General] Xileforce:
For whatever reason LZ4 is causing random reboots :/ I'm not entirely sure why ATM. Will play around with it some more.
[Galaxy S6 General] d3v1l.cr0:
Kind of surprised nobody is talking about battery improvements in this update. How does this usually work? Can we expect an improvement of any sorts when the update arrives? I'm new to the whole Galaxy ecosystem.
[Galaxy S6 General] Xileforce:
Usually you can expect performance and battery improvements. The android 5.1 update is quite big with many improvements and fixes.
[Galaxy S6 General] Jonathan-H:
All I want from the update is to remove the Sfinder and quick connect, and to allow an app like a game to stay in memory when you have 1gb of ram spare, without closing. I imagine the ram one will go unfixed as it always has in the past on Samsung devices. Memory leak and slowdown hasn't hit me at all which surprises me as every other Samsung i've had did this.
[Galaxy S6 General] mikeyinid:
What version S6 do you have?
[Galaxy S6 General] LNJ:
Tapatalk - > Chrome - > Facebook and then try Tapatalk again and it will redraw every time. I occasionally get TW redraws where my set wallpaper resets to a stock Samsung one.
[Galaxy S6 General] dwjp90:
Is it possible to change the zswap size?

Perhaps a significantly slower zswap will improve ram management?

Perhaps a zswap of 500MB.
[Galaxy S6 General] mikeyinid:
See the example script i posted, it reduces the size too ~500MB. But, I really didn't notice any difference. I went through services.jar yesterday and I don't see anything that would cause memory issues, nothing that stick out anyway. I hope it doesn't end up being a hardware issue, Samsung did move over to new storage and memory...

Any luck? I know [MENTION=3332811]faux123[/MENTION] and others have used lz4 in the past. Maybe look at their implementation?
[Galaxy S6 General] LNJ:
Coming from the M8, OPO and N5, it is ridiculous. Too bad it's not just a simple fix on the kernel side.
[Galaxy S6 General] mikeyinid:
The fact that samsung issued a fix update that didn't really fix it makes me wonder if it's even fixable.
[Galaxy S6 General] LNJ:
It's a software issue right? If it is then it's probably just a matter of time hopefully.
[Galaxy S6 General] JoeFCaputo113:
Soooo basically we are probably never going to see a fix from Samsung of this crappy RAM BS... Damn what a waste of great hardware in this phone.
[Galaxy S6 General] mikeyinid:
Who knows. I think it would have been fixed by now, surely. I mean, I'm sue it is software, but we have some pretty smart people here and if Samsung didn't/couldn't fix it, and community devs haven't with a kernel or framework patch, it definitely makes you wonder.
[Galaxy S6 General] Lockeskidney:
i hope this help. My S6 is painfully slow and im getting horrible redraw when going to home

Cant run Maps(nav), pocket casts via bluetooth together without crashing. Searching via maps is also painfully slow

i have 300-400mb free at all times
[Galaxy S6 General] iFlasher:
Hey. Maybe you can download a firmware from Asus Zenfone 2, and compare his services.jar with samsung galaxy s6 one.

The Zenfone is knowed to had a great multitasking experience, it can keep a loot of apps even in his 2GB version, and remember that Zenfone is in Android 5.0 and don't have any problem multitasking.
[Galaxy S6 General] Globalrebel:
If this is the case, I'll be selling the phone in due time. I can't believe a phone this expensive is having this bad of a RAM management problem.
[Galaxy S6 General] Cusa:
I have removed about 80% of the system apps from my S6 and it's blazing fast now. When I reboot my phone, I have around 1.6GB of free RAM and very little services running.
[Galaxy S6 General] mikeyinid:
You shouldn't have to remove 80% of the apps, and tons of functionality to get things working better.
[Galaxy S6 General] CQ7:
Did you see improvements in multitasking too? I hope so but i think you didn't. ...

Anyway i can't believe it's an hardware problem but of sure it's not simple to solve otherwise samsung would have already fixed it.
[Galaxy S6 General] Cusa:
Everything seems faster, from opening apps to switching between apps. I have also set the animations to 0x in developers option. Phone also reboots a lot faster now that there are very little system apps running in the background.
[Galaxy S6 General] iFlasher:
A friend tried before what you do (Remove a lot of system apps and bloatware), yes it gives more RAM and extra speed, but not solves in nothing the multitask problem.
[Galaxy S6 General] Cusa:
What issues are you guys having with multitasking?
[Galaxy S6 General] Xileforce:
Yesterday I experimented by completely removing Zswap from the kernel source. It made no difference. I have pulled a few commits and patches to the Low memory killer in my latest kernel release which should improve the way it decides on which tasks to kill as well as improving the overall performance of it. As for Lz4 I've used it without issue back on nexus 6. I have no idea why it's not working here. I'll keep at it though. Oh I also tried adding ksm and setting it to a ridiculous setting like scanning 2048 pages and having no sleep period so it was just constantly running and it didn't make much difference. :/ according to kernel aduitor from boot I have about 800mb worth of anonpages. I wonder if there is something here causing an issue. I attempted to add a patch which prevents endless growth of the anon VMA from upstream but it caused vootloops :(
[Galaxy S6 General] CQ7:
Anyway thanks for trying so hard.
[Galaxy S6 General] Xileforce:
I just made a dedicated thread for attempting to figure out the issue instead of continueing to clutter this thread.

http://xdaforums.com/tmobile-galaxy-s6/general/s6-ram-management-discussion-t3128229

I put it in T-Mobile only because that's the only device I personally own and can test on though I suspect the issue is the same across all devices.
[Galaxy S6 General] Hemant:
What apps have you removed?
[Galaxy S6 General] Experge:
Sincerely I don't multitask this much on my phone, so I don't notice.

What irritates me is that there's not option to deactivate the multi-window toggle that confuses with the notification pull down.

And the poor Bluetooth audio quality. The Bluetooth volume also behaves differently from the Nexus/stock, and it's worse (basically it uses the same volume for media/voice call as the Bluetooth volume, which makes no sense).
[Galaxy S6 General] 50103:
The Nexus 9 is plagued with similar issues too.Great hardware on paper ,but performance not so much.Poor battery life and heating issues plagued most users.

Subsequent software updates did squat to fix this.Finally had to get an idevice.Hopefully this does not happen to S6 and it gets fixed soon. :)
[Galaxy S6 General] KnownDominance:
Mine never had this in the first place
[Galaxy S6 General] Xileforce:
Idk if you guys have seen this here but I think we've come to a partial solution for the poor multitasking in this thread

[Galaxy S 4 Q&A, Help & Troubleshooting] Menkotucky:
Dont know if any one is facing the same problem.

Installed Lollipop in my S4 over the air, 2 weeks ago.

A week back, my phone entered into BootLoop mode. Phone gets re-started. I can see Samsung logo and it gets restarted again. I tried removing the battery and kept it back. Started working fine then.

Since today after noon, my S4 is in complete boot loop. Tried removing the battery and kept it back. Yet it is in bootloop.

Unable to enter into Developer options also. Please help

I hit the Power Button against a Flat Surface. It Vibrates and shows the Samsung Logo. But then it turns off.

Is the battery empty maybe?
[Galaxy S 4 Q&A, Help & Troubleshooting] Lennyz1988:
My guess is that your power button is faulty. Either try to wiggle it lose or replace it. It's really cheap

If it reboots in download mode and/or your recovery then it's your power button.
[Galaxy S 4 Q&A, Help & Troubleshooting] Menkotucky:
I tried it again with wiggling and hitting it a little bit.

it turns on automatically and then it turns off after some second again :(

Hey guys and gals I will be doing a full review in the coming days after using it but i did do an unboxing and first impressions of the LG G4 H815 in Red Leather....it is pretty damn sweet.

It's a little rough since i had a technical glitch during it but let me know what you think

[YOUTUBE]KntfJ-NAgMU[/YOUTUBE]
[G4 General] mcrane1981:
I was impressed when I got mine and saw the tan leather, but that red is even nicer!
[G4 General] jerflash:
Thanks! The tan one has the gold kept too right? You can pick up the red back for 60 bucks on ebay... It's pretty awesome
[G4 General] erwaso:
That red looks really nice! I got a case to simulate it lol
[G4 General] barondebxl:
I got the red one too and it looks absolutely fantastic. At first when i ordered it, i wanted the black leather one but they were out for a moment on ebay so i went for the red one. So glad they were out of the black one, this red one is the one to get.
[G4 General] jerflash:
This will be the first phone in a long time I will rock without a case of any kind. Feels to good in hand. Also can't bring myself to hind it! I will be getting a tempered glass screen protector just in case. The seller I got it from included a clear case that fits over the leather just in case I know i may be beating up the phone that day.
[G4 General] mcrane1981:
Yeah I've got the gold keys too! Think I'll be ordering the red today lol.

Do you see the "T" anywhere in your box?

Here is a pic taken with my Sony Z3 Compact that I may or may not sell. Still quite like it. Here is the LG G4 red leather compared to my BMW 4 series red leather. Both have German stitching so if figured it was a good fit... Hotness!

[G4 General] Chyeo1979:
Got the red leather too, absolutely sweet! If only the texture is like the black leather, should be able to withstand wear and tear a bit more
[G4 General] gtg465x:
The smooth leather actually feels nicer than the pebbled leather. It's a little softer, whereas the pebbled colors are sort of plastic feeling.
[G4 General] One Twelve:
Good choice this is the colour i'm most interested in. Not because i like red, in fact red stands out a bit too much and can attract attention.

But because it will look better than other colours as it ages. tan or black i can't see looking that good.

The smooth texture is a plus for grip. The gold buttons are a nice complement.

The other colour i like is the baby blue. Unusual colour to see in leather.

But you better have insurance.
[G4 General] jerflash:
No Insurance but the way the phone is shaped, the leathers feeling in hand, and how the devices is weighted...it does give you quite a bit of confidence when holding it. i dont feel like im going to drop it but i did feel like i was going to drop pretty much any glass backed phone i have ever held including my Z3C
[G4 General] One Twelve:
Good to know but it challenges my usual thing which is stick it in a bumper and forget about it. Can't do that with leather though so its one or the other.

user manual had this to say about leather..

[G4 General] yurushi:
Every phone I get I always have to buy a case for it but I felt confidence enough that I won't drop the G4 because I didn't drop my previous phones before. Just a few days ago on holiday I managed to drop the phone as I was getting out the car and it got hit badly at the top :(
[G4 General] Vto:

[Samsung Gear S] asidhowz:
Hi got the Gear S a few days ago and having a lot of fun with it..

Just wondering something, i bought my Gear s from a friend who purchased it in South Korea, its running latest firmware as far as i know as i updated the day i got it through the Gear app...

there is an app on the GS that has South Korean writing on it and a pic of a car etc I presume it is a navigation app of some sort because when i use the S-Voice Command to "Navigate to" it opens this app but its all in Korean and i havent a clue what it doing... is there a way for me to uninstall this app and set S-voice to use any other Nav apps i have installed?? itried uninstalling from the gear app but it is not in the list of apps..

S-Voice has worked perfectly for me on the Gear S and ive been using it quite a bit with great success except in the fact that for some reason Samsung have disabled it from doing some quite important things like setting tasks etc

oh yea one other thing, has anyone successfully used and installed NewsAce Rss App? i bought it last night and i keep getting a white blank screen when i try to sign in to Google on the app..

This truly is a smartwatch but could be so much better if Samsung allowed it to be.. its got plenty power etc so the lack of certain things is strange... real social network integration proper gmail etc etc Can anyone point me towards a File explorer that will let me view files on my phone.. would be great to be able to browse through folders and pick stuff i want ie proper music search of files i want to play and not just back and forth between last played etc!!

Im on a Note Edge..

Regards and thanks love this thing its awesome but again a bit artificially stunted by Sammy..
