[Q] Kitkat / Lollipop space useage - Nexus 4 Q&A, Help & Troubleshooting

Back on the old Nexus 4 for now. No idea how I managed with 8gb back in the day after enjoying 64gb with my htc.
I guess I'll need to be thrifty!! With the OS installed, it leaves about 5.7gb or there abouts. Give another 1gb or so to apps, another 1gb to various bits and pieces, it soon eats up.
I'm currently running the latest Pure Nexus. Out of curiousity what are the differences in the amount of space and Kitkat and a Lollipop OS uses? Is this simply negligable and nothing worth getting excited about?
Thanks.

[Q] Nexus 7 maintenance apps for Lags?

I just read this http://androidandme.com/2013/06/opi...-from-the-best-to-worst-tablet-ive-ever-owned
I was wondering about that as well; aside from continued use, the lags are more evident when it reaches the 9gb mark.
I have a 32 GB ram Nexus 7 and seriously; out of the 32 GB, we actually only have 27.5 GB storage.
I usually need more than 9GB of storage free space so i can have a buttery smooth performance.
Estimate 9+ gb to 10GB which means i have 17GB left to work with.
So far, I only discovered 2 worthwhile apps in battling this Nexus 7 predicament for non root users.
Clean master and Forever Gone.
Clean master is a great app for clearing files and releasing load from the 1 GB Ram.
While forever gone seems to work better than restore factory settimgs., it is somewhat slow and inconvenient.
Anyway, is there any other way to have better performance out of the Nexus 7?
Up to how many GB of free space you leave off before it starts to lag?
There was a discussion about this on AAA last week, but no real conclusions as to what might be causing it. One thing they mentioned was the possibility of the flash based storage "giving out". One guy commented that there are no real garbage collection routines present, so without a lot of free space, storage must be manually erased before being written to, and that can take a lot of time. This is why SSD's have garbage collection or trim routines running at idle to erase unallocated blocks.
It sounds plausible as our tablets are either being used or sleeping, with no real idle time for garbage collection to occur. Of course this is all conjecture at this point. I certainly see more lag in my upcoming 1 year old N7, but nothing like the unresponsiveness originally reported by folks filling up their storage, nor the symptoms described in the article you referenced.
But when mine goes belly up, I plan to move to an iPad. The tablet experience on Android pretty much sucks IMHO, and in the better part of the year in which I have been using it, it hasn't got much better. Of the hundred + apps I have on it, I can count on my fingers how many of them are actually optimized for a tablet.

[Q] any way to retrieve back the 1Gb RAM from GPU allocation?

Hello, I noticed that, from 4.1 to 4.3, ram dropped twice.
Now it's just a bit more than 1GB.
Well, I bought a device with 2GB RAM. I know, that's not completely wasted but allocated for GPU.
But... 1GB? On 4.1 we had 1.6 GB of real free ram, then 1.3 on 4.2, now 1.1!
And on kit kat? Maybe 512 MB?
Anyway. There is any way to get it back? Custom kernel? Custom ROM? No one tried this? I never compiled a ROM or kernel for android, so I have no idea where to start.
I think that's not an honest way of upgrading. 2GB was high end, and in android world would have been a lot of ram for a lot of time. 1Gb is just barely enough... It's already killing application, usually launcher or keyboard.

There is lots of information out on the internet for this very topic. I believe it has to do with more memory allocation set aside for GPU or processing.

I know the theory, I don't care why they did that.
It's like selling it for 2GB, then getting 1GB back, then... It's a 1GB tablet!
They should put 1GB for GPU and 2GB for RAM. You know, RAM, Random allocation memory, something that should be accessible from every application, not just locked there waiting for the GPU.
320, even 512 could be acceptable as a sacrifice for GPU allocation.
On PC you can even allocate 64MB on Intel chipset for GPU... And on PC you can have a lot of spare memory.
And on a tablet...One of the most powerful, and what should have been a top-sell for Google, you reserve a gig for GPU?
That's crazy. I almost feel scammed.
On topic:
Yeah, ok, but... If I'm not going to play. Can I flash a different kernel with some different init script?
I think that's something kernel-level. I didn't even rooted my Nexus 10, so I have not a lot of information, but it's not a common thing for tablet > 1920x1080 to allocate a gig for GPU. That's not right... I feel robbed this way.
I also feel the same way. On the nexus s forums there is a mod for kernels called bigmem, which takes some ram from some of the components and make it available to the system, for apps. I think the 1st ones who did this are the cyanogenmod team themselves, in one of their roms.
A kernel dev could do some mods to give more RAM to the user instead of reserving it, lots of phones have kernels like this. Also things can be removed from the ROM to free up more RAM to the user instead of it being taken by system services. I think this is also a lot of the reason we have less free now with Android OS version upgrades, because Google is adding a lot more services and these services take memory. We used to have 512MB of memory reserved for GPU, this was increased to 768MB in 4.2.2. I havent looked at the changelogs for 4.3 on this tablet but I dont think the GPU specifically got more reserved. That other 256MB lost over these couple version looks to do more with system services than GPU reservation.
That is my interest. Is anything available? I don't play a lot.
On an Android device, memory means future proof. Not totally, but a big part plays there IMHO .
1Gb is becoming low end, my galaxy nexus swap a lot if I don't remember to swipe away some application from the application preview button. And my galaxy nexus have 1gb - something like 230 MB allocated = almost 750 mb free. Not too far from 1100 MB free.
It will take a few application update, newer g+, Facebook, Google music and chrome et voila... You launcher will have to restart every time loading your 80 application, and the app will lose data swapping between applications (meaning that it was killed to reserve memory). It' s already happening and it' s sad, since it's a high end device.

I do not think anything is available now, everyone seems to be concentrating on adding features and functionality than slimming down and freeing memory. An example of what can be done is if you look in the GNex section of development there is a guy named mpokwsths with his "Mpokang kernel" that is removing things and slimming down the kernel to give more free RAM. I believe his thread says he is up at 772MB free on the GNexus now at boot. But no I dont think there is anything yet for the Nexus 10

The rumor is that KitKat will be optimized to run on low-memory devices down to 512 MB (the article mentions android 5.0 Key Lime Pie, but it's likely that's what's being released as KitKat instead) when it comes out in a month, again according to the latest rumors. Presumably it will run a lot better on the Nexus 10, but we'll have to wait and see. At least we'll get it within a week or two of release, :highfive: as opposed to the many months most non-Nexus owners have to wait.

Biggest problem with the 16GB G2 is...

Size! only have about 10GB available (pity there is no way to get into that other 6 gig) so after doing a nadroid (4gig) and Titanium backup (1 gig) with apps and things I'm left with only about 2 gig for movies etc which equals 2 movies at most, so yes size is the biggest issue, thats one of the reason I want to go over to CM or SlimKat (when they have stable builds... tried SK RC1 yesterday but its very 'buggy' kept freezing and rebooting my phone), cos the ROM size difference is quite big with stock based roms you can get away with about 1 gig, with CM/AOSP roms you can get away with about 300mb which is a nice space saving especially when space is limited like it is on the 16 gig G2.

You still won't have the full 14 gigs...

You can always go for usb host and those tiny micro usb flash drives.
But i agree, 10 gigs from device that cost so much is just horrendous
It could be possible to resize the internal partitions eg system, data etc but obviously a lightweight rom would be needed.

[Q] RAM missing?

Hi
I´m kind of new here but still haven´t found an answer why my Nexus only shows 1097 RAM instad of 2000? Even tried different hardware checker and they all tell me the same. Have I made I bad flash?

The 2GB ram on the device must accommodate both the operating system and graphics Ram before any apps are loaded. So what you see is normal. This is no different for laptops. Also the 16 or 32 GB internal storage shows less after formatting and Android OS plus Google apps (Gapps) are installed. At least with the Nexus 10 you have much less bloatware compared to other Tablets (eg. Samsung).

Thanks for you answer 3Dsammy.
I understand that you use RAM when things are installed, But I still dont get it. When I was on stock it showed in settings 2 gb RAM. And now Hardware info (app) System RAM 1097?. Same with Clean sweeper.

Nexus 10 has never shown 2gb available, I've had it since launch and I believe the most I've ever seen was back on 4.2 was about 1400MB or so, and it has gone down from there on each update. You never get what they advertise on the box, every single one of my devices has less than whats advertised, my Note 3 is supposed to have 3gb available, but really its only 2.38 after its said and done..
1098 is normal on 4.4.2 for N10, I've attached a shot from mine ... I can only assume most of it is being reserved for the GPU and its super high resolution.

Hi,
As already stated here, just clearing a little the information for you .
The Nexus 10 has a huge screen resolution, therefore it requires a more powerful GPU, even having a pretty powerful graphic processors which is the MALI, it's not powerful enough for the 1600p screen, so they allocated ≈1GB to the graphic unit to prevent any possible issues.
Also, there are some apps running in background, so it takes some RAM too.
Hope this clarifies a little ,

Thank for your help:good:
I did notice that with slim kat 4.2.2 I have 1647 ram available and with 4.4.2 slim kat I had 1099.
so I thought that Kit Kat uses less RAM but I don't really see it with those comparisons.

Is there a way of having the 3GB of RAM?

I saw this phone has 2.5 GB of ram and i read that it is because it has the other part for the system but i have also a Nexus 6 and it runs smoother.
This phone doesn't have better multitasking and i think it is for the missing part of RAM memory.
Moto X Pure has 700MB of Android OS
Nexus 6 has 478MB...
I have tried CM13 and Stock and truepure.
No.
That is not...
Just no...
Our phones have 3gb Android pre allocates as much RAM as it can the best solutions to your issue is just load a custom ROM if you go with asop based 6.0.1 it will mostly make this phone a Nexus
One way to look at it...
Why does your GB variant (16, 32, 64) not actually have that much available storage? The system is allocated some of this storage. RAM is no different.
As far as system allocation differing between different phones, there are potentially several reasons. Remember that the MXPE is not pure vanilla with Moto having some of their stuff baked in. This can make the difference. Also differences in Android version can be a culprit along with differences in any custom ROMs.
Some is likely allocated for the GPU, also there is zram (think swap in RAM or compressed VM, much faster than disk r/w), etc...
yes , i am with stock rom and just rooted , there is 2.5gb ram and free available always around 350 to 500mb maximum available , it does restart apps in 5 or 6 apps multitasking
