N9 - low memory issue
 

Hi.

It seems that memory usage on my N9 gets unusually high from time to time. When I have only few apps running (2-3), available memory is just 20-30 MB and phone becomes laggy (usually there is about 400 MB of available memory). Restart usually solves this, but then after some time this happens again.


Anyone have similar problems?


I have PR 1.0 still, but should get 1.1 soon.

Re: N9 - low memory issue
 

I've got the same problem. It is said that PR1.1 solves thos problem, however it is not yet available for my phone which has got a Swiss product code, so I'll just wait...

Re: N9 - low memory issue
 

You can't just, close those apps?
Didn't notice any difference on PR1.1, neither did i really have problem with free memory.
I would not care about the available memory numbers at all, it works differently in linux side, something you see on Android as well. Totally different to Symbian where you need to keep the memory high and it will always translate to speed.


Of course i can get my phone slowed down by something like Nokia Maps that's probably one of the heaviest apps there is. I just always close the apps that i don't need anymore. You get the ability to fully control what's on live on the background, but this also means that you need to manage the apps running.

Because of that both Swipe UI/Harmattan and Maemo 5 have had great integrated multitasking to force people to go to multitasking view.

Re: N9 - low memory issue
 

On my phone, all apps are closed and only WiFi-connection is established - and 920 MB of RAM are in use (30 MB buffers).

Re: N9 - low memory issue
 

I hope so. :)

It should come very soon in my country, I'll let you know did update solve this issue.

Re: N9 - low memory issue
 

Closing those apps doesn't have any affect, only phone restart.


I wouldn't mind if the phone wouldn't become slow in low memory condition. :)

When available memory is high, phone works much better.

Re: N9 - low memory issue
 

Arnt meego firmwares available like those for N900, like cant they be just downloaded and flashed?

Re: N9 - low memory issue
 

Is there any app to see RAM memory?

Re: N9 - low memory issue
 

Yes, but I actually don't want to flash - I actually don't even have a Windows computer, so I will wait for OTA.

The easiest way is opening a terminal and executing "free -m".

Re: N9 - low memory issue
 

Pr 1.1 solved for me those kinds of problems. Just hang on there until it's available :-)

Re: N9 - low memory issue
 

Yeah, Resource monitor (Rsc monitor).

Re: N9 - low memory issue
 

Awesome! Tnx :)

Re: N9 - low memory issue
 

Is this normal?

I think it's using a lot of memory.

Re: N9 - low memory issue
 

I'm on pr1.1, and according to the resource monitor app, when i have nothing open, my phone is using 900mb of RAM. Therefore I only have 100mb free...

Is this normal? Phone seems fine nonetheless

Re: N9 - low memory issue
 

We are on the same boat. It feels normal, but using 90% of RAM with all apps closed is not normal.

Re: N9 - low memory issue
 

I can confirm that I am seeing the same thing and I am on PR1.1. I haven't experienced any lag but it is strange considering that 90% of the RAM is utilized without any applications running.

Re: N9 - low memory issue
 

In the same time, Symbian Anna/Belle use just 45% of RAM.

Re: N9 - low memory issue
 

Loan it from someone for a few minutes - u'd remember & love those minutes later... PR1.1 changes everything! U then have a lovelier N9 experience, including better juice from the same power-pack [I don't know how!].

Re: N9 - low memory issue
 

At least a part of the "used" memory might actually serve as a disk cache that will be flushed once an application needs more memory.

NOTE - What is disk cache: As reading from RAM is faster than reading from persistent storage (still true even for modern solid state drives, as the one used in the N9) the OS might decide the cache data when it gets reading request so that subsequent reading requests are served directly from memory, not from persistent storage. It might even read a bit "around" the files it gets a reading request for. Result examples: Launching an application for the second time should be faster, working with a collection of files should be faster once the first file & surrounding data is cached in RAM.

NOTE - Free RAM: It sensible to use all available RAM, even if there are no applications needing it at the moment - it still needs to be powered, even if not being used at the moment. Caches are good candidate for all this unused RAM as they generally can be easily flushed (they just cache data available from somewhere else for faster access) once the RAM the occupy is actually needed by applications.

Re: N9 - low memory issue
 

I think it's normal because there is plenty of free RAM memory and low percentage of swap memory is used.


In my case, only 20 MB of RAM is free and swap memory is used in much greater percentage. That makes my phone laggy :(

Re: N9 - low memory issue
 

Like i said on my previous post, this is normal on linux.

Linux uses any free RAM that it has for caching purposes. It will be reallocated when there's a process needing for it. Can't be compared to iOS, Symbian etc.
If your phone is lagging, that's a different thing, but don't worry about the RAM because of those numbers. It was the same on N900 as well.

Re: N9 - low memory issue
 

Same problem here , the phone runs out of memory too fast and reboots . Some people from nokia forum said it's hardware problem and a factory fault and many of them got a replacement . So I sent it to nokia care and now I'm waiting for it to be fixed or replaced .

I'm so dissapointed , nokia made only one meego device and that device comes with bugs from factory , shame !

Re: N9 - low memory issue
 

iOS uses all available RAM too.

Re: N9 - low memory issue
 

Yeah, my N9 had few automatic reboots and few times it just stopped working. :(


Do you have links to that topics from Nokia forum?

Re: N9 - low memory issue
 

OK. But why then phone becomes laggy?

How are your experiences? Do your N9 works without slowdowns all the time?

Re: N9 - low memory issue
 

Didn't you say you were still on 1.0?
Lag etc. is improved considerably with 1.1.
A few users already told you that earlier in the thread.

Re: N9 - low memory issue
 

Well it's no iPhone. Everything still seems to take its sweet time pretty much all the time.

Re: N9 - low memory issue
 

This is the link : http://discussions.europe.nokia.com/...ighlight/false

I think everyone who has this problem and sends the phone to NC should mention this link (topic) too . Maybe nokia will admit they made a device with a faulty hardware and replace all phones with this problem .

Re: N9 - low memory issue
 

Well, there is lag and there is "lag" :D


In general, my phone is rarely laggy. But in "low" memory condition phone lag is much more visible. I'm not so sure everybody experiences latter case, that's why I'm asking.

Re: N9 - low memory issue
 

Thanks. I'll wait for PR 1.1, if it doesn't fix this problem, I'll send my beauty to NC. :(

Re: N9 - low memory issue
 

When no live apps are running? No there's no lag.
When i put the heaviest app there is on the background, Nokia Maps or multiple apps, yes there is lag. Using PR1.1.

Hopefully you get it working. Wait for the PR1.1 at least or just flash it like me.
