z1 Multitasking solutions ( fix) - Xperia Z1 General

Hello, as all of you know the Z1 has very bad ram management, and apps reload most of the time unlike other 2gb ram phones
i used ram expander ,worked very good for a month, then my micro sd died.
please everyone share his solution or alternatives and thanks.

I think too many people are blaming the wrong thing for the wrong problems.
No proper testers for roms... so the wrong thing gets fixed.

Kernel Auditor has Virtual Memory and LMK settings. If you want, have a try.
Anyway, is there any relation between Virtual Memory and Dead SD Card?

Not sure how Ram expander works, but it might just be those programs that create a swap file on the SD card - so i'm guessing that since data is constantly being read/written all the time to the external sdcard, it uses up the limited lifespan of the device. But it might just be a coincidence that this breaks the SD card

Yeah unfortunately SD cards don't like being constantly written to.

Yes it does. Nearly everything has its own lifespan. And in case of TLC Memory, it often happens.
However, since that TLCs are usually slow and not reliable, it shouldn't be considered as a main memory. There are some alternatives like MLC Memory.
And... cuz SONY Xperia Z1's SD Card Slot is even pretty slow, it is really slow compared with internal eMMC memory. It is definitely not for cache memory or virtual mem.

Speed or no speed.
SD cards don't like the abuse.
At hackaday we did tests with several SD cards to see how long different cards survived in a raspberry pi.
All of them failed in a very short time.
The constant reading a writing wrecks them unlike SSD drives that have RAM to help them cope with this constant write and erase..

Maybe i don't use the phone so much or don't have too many apps to put the phone really under stress but to me it really seams like the phone is flying. Or probably it's because i came after a samsung experience before i got the z1. I've never experienced app reloading until now, only an app crash, but it was because of the app (chromium for snapdragon).

Actually, I don't know that. No matter what I do, the available ram doesn't go below 800 mgb. I even turned off swap to gain speed and disk caching in Firefox. Believe it or not, but this also helps to lower CPU temperature by about 5 degrees.
Get rid of bloat both Google and Sony or better go for a custom rom.

have you tried some debloated and tweaked rom?

it's the same, i had lg G1 , G2, galaxy s4 and i could open too many apps and games without getting any reload, but on this z1 4 apps, or a game and 2 apps, and boom, reload ...,
happens on kitkat, lollipop too.
i swear on my optimus g, i can open asphalt 8, asphalt nitro, gta san andreas, with fb and messenger on background, and i still get like 400mb free ram.
each game consuming near 200mb ram on task manager

5.1.1 came with great RAM optimisations and they streamlined the system apps memory usage greatly. Secondly it is all relative to what apps you got installed that run continuosly. I just cant relate to your problem with my Z1 as I just had a few times it has run low on RAM (LP 5.1.1) and that was switching between photo album and heavy photo editor (Polarr) after half an hour.
About the games well.. Optimus G renders it in 1280x720 and the Xperia Z1 at 1920x1080 which requires more RAM for the framebuffers.

Z1 compact has 720p and its ram sucks like z1 and z ultra

I finished Doom3 on my sgs4mini....
I cant get past the second level without:
1. overheating.
2. auto close.

Just set up your phone new (Clean Install through PC Compain) you notice that most user are happy with the Multitasking management of the Z1 always include me too.
Just flash your phone new to a older software (4.4.4) debloat maybe increase the swap profile( I deactivated mine completely swap=0 and happy with multitasking)
Also
Flash new Rom
Try Custom
Try new kernel when open a bootloader don't kill you
Be smart optimize it.
Buy new phone or go again to Samsung.
But please stop crying here

How to add more ram to our tiny devices(Through SD card;) )

http://forum.xda-developers.com/showthread.php?t=683123
How to use Swap space on SD to increase ram on our devices so we can run more demanding apps.
swap is possible only with custom kernel, so it will not work for us
I believe that doixanh proved more than enough that custom kernel is not needed for any kernel modifications Still, we would need a module.
but i don't think that he should make swap module it will be better if he will finish this
Well, it's up to him what he wishes to develop
IMO swap is useless for Android. It has its own memory management already.
And it would certainly take a high class sd card, AND it would be harmful for it So next time we should just buy a phone with bigger RAM memory

But what do you need slow RAM for? RAM is very dynamic and since we already use app2sd it could even slow your device down instead of enhancing performance...
EDIT: Well, maybe it would be faster if you have a class 10 card...
Yeah SD is slow and putting swap there will be incredibly slow.

Yes, but i want this because you know that there are some applications that won't run on X8 because of it's low ram...so, i dont care about about speed, also, i don't use app2sd, so no slowdown, I am using Class 4 card
Yeah I know. Just my opinion

So, is there a way of using ram just for the ram consuming apps, to make X8 able to at least run them? (You already released an SD card speed fix, so it should go a bit faster...Can you help me, cuz i really like running RAM hungry apps and i don't have enough ram :|
No I don't know about that. Haven't tried swap thingies yet
for example, there are games, like dungeon defenders that requires 256 MB of RAM at the runtime (it's the requirement of unreal enginge 3 i belive). some guys have managed to run the game on LG swift, which is pretty much the same device as x8 when it comes to hardware. maybe it's not running too fast (although i saw some video where it was even faster than on some more powerful devices), and it's not quite playable, but some people might still enjoy it. and without SWAP, it's impossible; and it's just a one example.

RAM

I have rooted my Asus TF, Put on the H 3.1 os, used Clemsyn Blades kernel, running very nicely. I have rooted it, and uninstalled crap like facebook, books, splashtop etc...lot of useless bloatware is out...However here is the problem........LOW MEMORY....This machine has ram of 1GB, and only 800mb shows, so almost 200 for the GI, and out of that 800, about 400mb is always used, despite using various app killers, I think we should be able to get it to about 200mb used? anyone know where so much of ram is bieng eaten
My question to you great knowledgeable friends is;
1) how to get rid of more useless apps eating memory
2) does using a different launcher reduce ram eating?
3) is it possible to achieve about 200-300mb consistent ram?
This is an awsome machine, I think more tweks we can make is super. I have a Samsung GS2, I have removed most of the stock stuff on it and set up my ownlauncher etc. It runs with amazing memory, 500mb free, and awsome graphics interface. Less nonsense.

If you haven't done so already you could use Titanium Backup to remove more stuff (including system apps) since you're rooted. I would advise caution however in case you remove the wrong thing. Perhaps someone else can post regarding which particular system apps are safe to remove, as I haven't expreimented with this myself.

He could just freeze them first and play with the tf a couple of days and if there are no problems, delete them.
Removing junk isn't a bad thing to do, but in my experience, app killers do more bad than good in android. Other than in windows, you don't need tons of free ram to run apps smoothly. Android has a great ram management that fills your ram with apps for fast access, and closes the least used/needed when another app requests more ram. So if you use an app killer, your tf will have more to do with restarting the apps you just closed and your performance will actually decrease. Google it and you'll know what I mean.

As i said before, much ram usage isn't necessarily a bad thing. It only eats performance if a running app is badly coded and doesn't give its ram free when required. Then you better kill this specific app instead of autokilling stuff. Well coded apps won't eat your performance, no matter how much ram is used.

300Mb oof ram are dedicated to Nvidia Tegra 2. For this reason you read "only" 700Mb. Maybe in near future we will able to allocate more memory than 256Mb to our Tegra 2
memory usage doesn't mean too much now if the app/programe is properly coded, when needed, android should be able to release them on the fly......
same goes to my windows 7 machine, it's got 8 gig memory but the free memory always remains under 500M because the system is using them to cache most recently used applications.
Constantly clearing memory will not help too much, and believe or not, it worsens both the performance and the battery life..
but again, android is not as robust as windows in the terms of memory management, so it's not a bad idea to occasionally take a look at the actual memory usage but just don't go too excessive...
Screwing around with app-killers is never a good idea. Are you actually experiencing issues due to insufficient RAM? I've never had an issue with RAM on my Transformer. Android is much better at handling its memory than people are, let it do its thing.
And for the record, RAM is there to be used. It's the fastest memory a device has, so the more it makes use of, the better. If something else needs more RAM, Android will flush out something that doesn't need it.
I think app-killers are one of the biggest issues with Android, in that people seem to think they're necessary. Unless you actually have some app that's misbehaving or has a memory-leak or something, you shouldn't ever really need to manage your running applications. Just leave it all alone for a while and see how you go.

not at all. The machine is fast, its very quick and loads things quickly. The only time I had problem is using logmein, it crashed and said out of memory...I was a bit perplexed. I cleared a lot on my SGS2, and it was much faster.
Let me know any ideas, otherwise, as suggested, I will see how it goes
From my previous experience with Android devices, it's nearly impossible to increase the amount of free ram. I've tried, and only found one solution that I'll talk about later.
This isn't a bad thing. Ram is not CPU usage, and ram is going to use roughly the same amount of electricity regardless.
What android does is fill up the ram with programs that you will potentially use. That way when you want to use the program, it's already loaded in memory. When you load another program into memory, say a game, it will close apps to make room for the new app.
If you really want more memory, the closest thing is a swap file or partition. I use one on my phone, and it helps a good bit. Don't know if it would help the TF101, since it already has 1GB ram.
If you are still set on more free ram, try a program like auto memory manager (there is also another program very similar, has a blue fish for a logo but I forget the name). This doesn't kill apps in memory. Instead it changes the the when android closes programs in memory based on how much free memory is available and the priority of the program. I used it before on my phone with pretty good success, but now I use a swap file instead.
Right now I don't use a swap file or memory manager on my tf101, sine it runs great without it.
Thanks for all your responses.
I think this article should explain how Android 2.x operates. Even though the article is not about Honeycomb (Android 3.x), I doubt Google has changed how it manages memory in Honeycomb.

I guess its okay to use swap. Swap increases your ram and so you can preform better multitasks.
I think the con is that the phone gets slow if your SD card is not good. But i am really not sure on this one

SWAP expands your RAM, so when you have it, you can open more apps than than you could without it.
If You're not trying to run many RAM-eating apps at the same time, you're only wasting your SD space.
I close every app i don't need, so SWAP i useless for me. Also i'm using Dorimanx ROM, which when SWAP is enabled has no built in task manager. If it wasnt like that, i would probably have it, just in case.
About slowing phone down: SWAP will never work as fast as RAM, since it has slower access time than native RAM. It's just to keep everything going even if you ran out of RAM, maybe a little slower, but still.

[Q] RAM on I9505

Hello guys,
i can't understand where disappear 2Gb memory on SGS4 i9505. I use stock ROM, minimum one time per day i need clean memory through "active aplication" manager because phone unresponsive, it is same situation as on my old phone SGS1 I9000 (512mb RAM). Even all aplication cleared still used 1.2Gb RAM of 1.78Gb physically memory. This is normal or i need begin flash a lot of custom ROM's for find something useful that realy works??? What is better way?
Thanks in advance for answers.

Stock ROM is full of bloatware and stuff. This means you have a ****load of useless apps running in the background, and some useful ones too. You should root your phone, go to application manager and DISABLE all of the useless bloatware you never use (use caution though - some things depend on others. For example don't disable google services if you intend on using any of their things).
There are many apps out there which show you what's running in the background and taking most space. Are you sure your phone feels slower or it's just the RAM that worries you?
Keep in mind that apps keep running in the background so you can later open them quickly, so if you force close them the next time you open them it will be slower.

Yes, i feel that phone slower, i wait too long time, while i check RAM it is almost full, and after cleaning RAM phone is more responsive.
Ok, i'll try disable some services in background with root phone, thank you.
I'm still using mine on the unbranded MDM which came with the phone.
I will wait a couple more days, and if they will not release a BTU update, i will flash the DBT one.
Since i have the phone ~May , i never had those lags and redraws like i see here from some users.
I'm not rooted at the moment and if i use apps/games and i just exit them, used RAM drops to ~0.98, i never clear them from memory, but if i do then the used ram drops to ~0.87.

it saves a little bit of battery.
but setting limit is not so good for multi-tasking, some apps (not cached in the background) will take a little more time to open, maybe you will not notice that. so if you set limit for example to 2, open running app in setting and press on "show cached process", you will see only 2 apps are cached in the background

Yes, i did it, now on phone "Background proccess limit" is 4 app, but in any case during normal phone job 1.1Gb is used.
Simply i compare with my previous phone galaxy s I9000 that flashed with custom ROM on android 4.1 (comparable software) and i it perfectly and stable work with 512Mb RAM and 1gb (one core) proccessor. I don't play with games and don't feel high difference between two absolutely different hardware's & devices (i don't speak about screens). Old phone work very smoothly, it only uses half as much system resources relatively to new galaxy s4 i9505. Why i need use "Background process limit" option on newest device with 2Gb RAM, even think about it? What is payment for biggest high quality screen?

Lg d722 ram expansion? [howto]

Greetings fellow persons
I have a LG D722 and I wish to breathe some new life into this phone
I have heard that you can expand ram with the use of an sd card
Here are my questions
Does my phone support such a function?
IF root is needed, will it still work after i disable root?
Do i just get a 10 speed XXGB sd card?
What would be the best sd card to choose in terms of speed (that the phone supports)
What (free) app should i use?
If you need any additional info, let me know
Thanks

This is not possible. Even if it was possible, it would be way too slow because ram is way faster than an sd-card.
EDIT: You can use a SWAP file, but you can't use it as "Real" ram

I had the "real" g3 with the snapdragon 801 and 3gb of ram so I didn't had to do anything because it was a great phone for the price.
But, before that I had a really bad phone with only 512 mb of ram and I tried everything to make it go faster (overclock (witch make the phone really hot), "ram booster" kind of app (they don't make any noticeable difference), etc...) but I realised that we just can't do that. So, unfortunately, we have to live with it until we change phone.
That being said, you can always disable animation to help the device go faster but that's pretty much it.
Yep done that it helped a bit
I am using "root booster" it makes my device react quicker then normal, i noticed the difference right of the bat
And got rid of some of the bloatware, am currently researching which other ones i can safely remove
