[Q] CM10 Memory Footprint & Reboots

Hi,
I have a P1000 with CM10 (Humberos and Alroger) and I'm very pleased with this ROM.
It's such a difference if compared with GB that it really looks like having a new device.
There is one problem though that I'm not sure can be fixed: the random reboots.
I've dig a bit and apparently reboots are related to the lack of memory.
Analysing the available memory indeed I noticed that it easily goes around 50-70Mb which doesn't seem to be that much and probably this is the root cause of the random reboots.
I've enabled zRAM with a compression rate of 35% but this doesn't seem to have solved the issue.
So I'm wondering why nobody else is actually talking about this issue. Is the majority of P1000+CM10 users not having this issue?
Or it's just that we can't do anything about it and therefore we have to live with this?
In no way this post wants to be a complain. I'm just asking some more information to understand this issue better.
Cheers

Free memory is wasted memory.
This is not Windows which actively swap memory to swap.
if memory really is running low, the memory manager will kill inactive apps, not panic and reboot.

Hi Pryiana,
I'm not sure I got what you mean.
I'm not rebooting the system, it just does it automatically, that's the problem.
What I'm trying to understand here is why it reboots automatically.
Based on Alroger a solution to self reboots is to enable zRAM which is a kernel feature to compress data being written to memory to reduce the footprint.
Are you currently on a CM10 ROM?

I am on aokp jb using humberos kernel (forgot which date)
My point is :
the system reboots you are seeing, it is not because the ROM isn't providing enough free ram. It is something else. Maybe even because the memory manager isn't doing the right thing.
Maybe true that your attempt to free up more ram improves it, but it may just help to avoid hitting the real bug.
Anyway, I am not a dev.
Just a system guy.
I just want to say free ram is wasted ram.
In Linux systems, the kernel grabs as much ram as it can. Not free them.

OK, I see what you mean.
BTW, I can see from the cm10 thread that other people are having the same issue with the device restarting after a while.
Apparently 512MB are just not enough for Jelly Bean.

Err... Not true..
I am using AOKP JB for SGT7 by stimpz0r and no reboots for me.
Maybe cm10 not ready yet

use some troubleshooting tools to find whats happening, maybe some app runns wild for unknown reasons.
Check in development settings something with show cpu stuff, that can be handy for that. It shows cpu utilization etc. Any process nane there you can google.
if in doubt, go to settings, apps, running, turn some stoff there off, go to cached in same screen, repeat, go back and forth till you find the filthy process
at own risk off course.
its possible an app uses you data a lot and hoggs it, plenty of ways finding that out, like set everything to manual sync to eliminate.
check which apps use lots of data, etc.
Or root device, warranty now void, all own risk, get autostarts app and check those on connection triggered. Disable the buggers you wanna keep.
when culprit found, find developer thread or website and report the bug lol with proof its that app

Thanks for the info..will try these things out .

You mean on downloading and installing apps,right? Or your phone lag with data ON without any download?

New P7300 XXLQD

Has anyone noticed, installed the latest wave of European firmware? Sammobile has a Feb/Mar release XXLQD for a number of regions.
Curious to know what changed...
Sent from my GT-P7300 using xda app-developers app

I installed the feb update for nordic contries a week ago, and together with A1 1.8.3c, this one is super slick and smooth. Could be that it's no more smooth than other ics-versions, but in my head it is, and that's what counts.

Try another launcher. I use adw ex, which s really nice and smooth.
Sent from my GT-P7310 using xda app-developers app

The launchers from Play Store uses more energy(around 30-50% CPU).I have seen that touchwiz from Swiss rom uses around 15% CPU , is very good optimized(compared with honeycomb launcher).The lag problem is touchwiz specific( you can see that in Galaxy S4 hands-on on Youtube).

Does anyone notice specific improvements compared to the Nov/Dec releases (European XXLQ6)

I'm not sure. I think I've been on almost all of safarikings older ROMs (up to v.4.0.x.x). But as I said it could all be in my head. I do however notice that hitting the home button results in a silky smooth transition, whereas before it stuttered like hell (even with adw ex).

It is worth trying it? Im am currently in LP7 and I have to say that I am satisfied, however I notice that sometimes the tablet gets dark and it forces me to reset by holding the power button.
Despite that I got HDMI, phone calls (with its bugs on) and all necessary things I need.
Is it LQD more stable?

Whatsapp service gets restarted on heavy ph usage and then it looses internet connect

Hello
I am currently using cm 4.2.2 by bieltv3
The problem i hav been facing from the time i installed custom roms is that whatsapp, once it gets killed by android like when there is some memory intensive app, it gets killed.
It does restart bt unless i open it manually it doesnt receive msgs.
The service is active bt it simply doesnt receive msgs.
But once I open it manually it works flawlessly in the background unless it gets killed again.
I have removed apps like greenify and i never kill it by long pressing the home button.
Also i always have 85+ mb free ram.
This did not happen in stock rom when free ram was even lesser
Can anyone help me to fix this issue.
My 2g connection remains on 24x7 for whatsapp and i need it to be functioning all the time.
Thanx

Dude i have also tried 4.2.2 and have found similar kind of problems. I think this is the problem with the task killer. Try usin another Task Killer but dont forget to White List Whatsapp so that it does not get killed.
Also if you wana use stable 4.2.2 try out Spacecaker's SGS II Rom v 11.2 or S'Periance Rom.

Yeah I know but in terms of stability are actually lot better than 4.2.2.

Solved it partially by using memory manager app
Decreased the limit for background apps from 30 to 5
Whatsapp is much more stable nw

[Q] What is the advantage for choosing CM

What has CM for advantage above fw or other rom's?
Sent from my GT-I9070 using xda app-developers app

A clear difference is speed. No more lags in opening anything which is the major drawback of official jb.

How about battery performance. I now use dxamd1 with cocore 6.8. And I charge once a day in the nightly hours. And use my phone freqently the whole day

Battery is quite good for me. A good start considering the rom is not optimized yet.
Sent from my GT-I9070 using xda app-developers app

Battery life is amazing, considering cm10.1 is still quite raw. I've just plugged my phone in after 2 days.. 15% battery left. Some whatsapp, some messaging, some browsing, some music... the usual stuff. Wifi on 100% of the time.
So is speed, smooth as butter. The only drawback I was able to find so far is benchmark results... ran antutu and scored 5030 points, while the better stock JB roms are near or at 7000 points. Mind you, if I hadn't run that benchmark, I wouldn't have noticed there was a performance deficiency.. no lags, no hiccups, nothing.
If you don't use video recording, and don't mind turning the volume down then up during a call to solve the low volume problem... then yes, go with CM10.1 as it is right now, it doesn't dissapoint. It can only get better!

So wich cm Rom version comes out best out of the box here. And can i flash it over all fw versions?

I hope that the issue of video playback is resolved soon!!
That's the only reason I don't try cm10.1
I think it will be fixable, I remember the times when g5 cm9 didn't have hq acceleration

Well, there are a lot of CM10.1 nightlies... Have a look in the archive, I've personally had excellent results with the 20130621 one. Don't flash the latest 20130627 since it's corrupted (it weights 94 MB and a full rom is about 165-170MB)
From what I've read so far, CM10.1 works just fine if flashed over XXLQE firmware, but could have problems if using another one as base. I used polish XXLQE as base and it worked perfectly, apart from the two or three bugs CM10.1 still has.

I think cm 10.1 and pac 23.0 works well with any other base too. I'm using indian ddulp8 and got no issue at all. But better install from fresh stock firmware to avoid any problems.
