Can sombody answer this q about memory ram ? - Lenovo P2 Questions & Answers

why 4GB Ram is showing 3,5GB ....and system take 1 GB to have only less than 2.5GB to use
in percentage the system take 40% of the Ram ....and let u have 60% of use ..
i think this is a little bit high ...

Basically, when you start an application, all the functioning parts are transferred to the RAM and is executed and run from there. This makes it easier for the processor to transfer and exchange data. However if it had used the secondary memory (internal memory or SD card) the data transfer will be slower and thus slows down the entire process.
Similarly, the system has some core functions that are needed for the device to keep running. These critical files are stored permanently as soon as your device boots up. After which, all other apps gets booted up.
You can get some part of that 1 GB memory taken by the system if you could uninstall some of the unnecessary system apps like bloatwares.
This is same across any device. Hope I cleared your question

A full ram is a well used ram.

[Q] Internal phone storage - cant use available free space

Can anyone shed some light on this problem (or perhaps suggest a fix).
My HTC EVO claims aprox 40MB available space of internal phone storage.
(Menu > settings > SD & phone storage > Internal phone storage)
When my phone has about aprox 40MB I begin to receive "Low disk space" notification. Furthermore, I cannot install any other app.
The problem here is... if i have 40MB of available space then i SHOULD be able to install (afterall I have 40MB free).
Is the reported 40MB erroneous? Perhaps this 40MB is reserved? If it is reserved, for what? And if it is indeed reserved for something, why is it reported as 40MB free?
Perhaps others have run accross the same issue with a different reported space available (mine was 40MB. others may have other values).
There are threads with a seemingly similar issue (disk space being eaten up and memory leaks), but not quite the same as this one (unable to use free space availabe).
Please advise.
Edit (added more info)
Some additional information to what ive posted above....
I am running Froyo (2.2)
Kernel 2.6.32.15-ge2fb08e
Software version 3.29.651.5
This problem has occurred when I had 2.1 (before froyo OTA update).
This problem occured when I have Froyo
I rooted (sucessfully) last night, and the problem persists.
If I am at aprox 40MB, if I remove an app to free up some space (lets say 10MB), which would put me at 50MB free the I can continue installing apps again until i reach about 40MB. Then i get the "low disk space" notifications and cannot install any additonal apps again.

Why dont you just use darktremor apps2sd?
Sent from my PC36100 using XDA App
thanks for the quick reply futuristicstyles.
The issue is not being able to free up additional space. The problem is that the phone is reporting I have space available (40MB), but when I try to use that space it wont let me.
until the experts chime in, i think it does have to do with memory allocated to the os that may include space reserved for cached files, mail attachments program usage, ect. or it could be a buffer memory when the developers designed it.

Welcome I use to wonder the same thing I think the phone does that so that it wont slow down or start force closing like winmo phone when they get full it starts freezing and, moving like dial up. Thats why i think the phone does that
Sent from my PC36100 using XDA App
But dark tremor is a great alternative i have over 200 apps installed and my phone us still on top of the quadrent no lagging what so ever only when rebooting has to load apps from sd card

Thank you all for posting.
Just checking if there is any additional advice or suggestions?
Also, has anyone else noticed behavior?
I agree with everyone else in that it's probably reserved for cache. Normally the phone uses /data for dalvik cache. Custom kernels and ROMs sometimes have a script that moves the dalvik cache to the cache partition, freeing up space in /data which I might suggest to you in this case.

[Q] Any fix for system instability after moving too many apps to SD card?

I have seen several conflicting threads on this, but no clear solution. Basically, the problem I have is that if I move more than 50 or so apps to my SD card (I have heard others complain about the problem manifesting at around 70 apps) a race condition occurs during the card scan, which since it doesn't complete before a timeout, causes the phone to soft reset (basically reload just the top level OS above the continuously running kernel). These resets then continue to occur at semi-random intervals, such as every time you try to access the memory card. So far, the only fix I have is to delete apps from the SD card, and it really doesn't matter which ones they are, only that above a certain number, the system becomes unstable, and I presume it is because the system cannot index all of the apps fast enough. I can't believe the stupid Samsung engineers never thought of fixing this.
Anyway, I am running a stock, rooted kernel, stock ROM, but the internal memory is nearly full with all of the large applications that for whatever reason cannot be moved to SD. Does anybody have any viable options?
I have heard of some people using app2SD. I have heard of others remapping their external storage to sd_card with the USB storage mapped to sd_card/external_sd. I tried replacing my memory card (Sandisk, 16GB, Class 2) with a brand new, out of box (Sandisk, 16GB, Class 6), and I am still limited to the same number of installed apps. I'm not sure, but I think the number of active widgets on the desktop may also be a contributing factor (all of my widgets are stored to internal memory).
I have about 180 apps on my phone and have never run out of room; what do you have on there that takes up so much space?
if its data, then move that to an external sd...

Well, first of all, I've never removed the Sprint bloatware. I also have the Amazon App store and (on the assumption that my SD card still has gigabytes of storage) pretty indiscriminantly "purchase" and install Amazon's free app of the day, plus all the other apps I've gotten from Google Play. By latest count, it is around 360 apps, and that was after I deleted several large apps that for some horrible reason couldn't be moved to the SD card, including PoolBar (50MB+), Android Phrase Book (26 MB+), some other tennis game I got from Amazon (20+MB), none of which gave you the option of offloaded to SD. About 110 of the apps were games, 25 utilities, 24 media apps, 20 social networking apps, 19 shopping apps, 17 travel apps, 16 PIM apps, 11 photo manipulation tools, 11 internet apps, 8 maps and navigation, etc.
Complicating matters, Android has a /data/data directory which has soft links to all the applications installed on your system, regardless of whether they are installed on internal or external memory, and each link must be the filesystem minimum 4KBs each. Looking at root explorer, I see that this directory alone is over 300MBs of internal storage.
well, the answer to your problem is easy; get rid of 1/2 the **** on your phone that you never use, and you will be fine!
if you don't use it every day or at least once a week, its gotta go

I can't imagine ever installing that many apps, but whatever... If it we me, I would start by trimming off anything you "know" you have never or will never use. After that I would concentrate on putting the biggest apps on the SD card and the rest on the internal. I have 122 apps installed on internal only with much room to spare and I am sure there are things I just will never use. LOL

It really isn't hard to use a bunch of apps, particularly with all the websites, including this one, that have their own viewer apps (or Wikipedia, urban dictionary, etc.). Anyway, I have all my apps in folders so it still only requires 2 pages of apps. I think it is stupid that they designed the operating system so that you would be app limited, even with an unlimited amount of storage via the sd card slot. I hope this is one feature they fixed in ICS. A much better strategy for exploiting the multilevel memory architecture would have been to allow the user to install ALL nonessential apps to the SD card by default, eliminating the need for soft links in internal storage, and then use the internal storage as a nonvolatile app cache with an LRU replacement policy. This would then give the most commonly used apps the performance benefit of running from internal storage without the user having to go moving crap around. It would actually be very similar to what Intel is now doing with solid-state drives as a hard disk cache with the new Z68 chipset.

[Q] How much app storage do you use?

I have noticed that when I first install a new ROM--GB, ICS, or JB, doesn't seem to matter--my phone runs lickety-split fast and is wonderful.
Over the course of a few days, though, it starts to become sluggish and laggy. When it starts to get extreme, the OS will frequently pop messages about "xxxxx is not responding. Would you like to close it?"
The only possible correlation I can discern is that this sluggish behavior seems to get worse when I install more apps. I am running the EXT4 unlimited data mod, and typically have ~200MB free in the /datadata partition. I think I start seeing the sluggishness when /datadata free space starts dropping into the 400-350MB range or so.
Have other folks noticed similar sluggishness? Has anyone else figured out what the trigger for it is, and how to avoid it?
I'd be curious to see people respond to the following questions:
1) Do you perceive your Inc to be generally "fast" or "sluggish"?
2) How much free space is in your /datadata partition? (Does anyone _not_ run the unlimited data mod these days?)
Thanks....

I think mine is mostly fast. It sometimes bogs down, but usually recovers without reboots or fc's.
I am using the ext4 mod, and i have 243.44mb free in data/datadata at the moment.

I do not use the unlimited data mod, I have been managing with a 150Mb /datadata partition. I don't use Facebook or Chrome, I know Chrome is a huge space hog and I've heard Facebook is too. For me the biggest downside of not using the nodatalimit mod is having to keep a decent number of apps on the sd card (some apps, when moved to SD, take their /datadata junk along with them), which makes mounting and unmounting it pretty slow, also slows down boot times. I rarely unmount the sd though, I typically copy stuff to and from an SMB share on my desktop computer - but I digress...
1. My dinc is pretty fast. I have seen more of the slowdown you describe on other people's phones and on my own phone with ICS/JB. (JB was especially bad when we had the bug where the CPU max frequency would get stuck at 614kHz). I ran Ice Cream Senseless for several months (which is GB/Sense themed and stripped), often saw uptimes of over 200 hours, and had zero problems with sluggishness or FC's.
2. Currently my phone storage partition shows:
/data 748M total, 223.7M used, 524.3M free
...and my /datadata partition shows:
/data/data 149M total, 117M used, 32M free
Titanium Backup gives a nice breakdown of how much storage apps are using, though it takes a very, very long time to calculate it.
the biggest space hogs for me is email(i have 4 accounts), facebook and a few you don;t have control over like Google Maps, Amazon App Store, Text messages, ect....So for me, I was easily exceeding 70-80 MB out of 150 for just data. Hence, once you get to below 20-30 mb free, the phone becomes unstable and in danger of going into a boot loop. I was able to use APP2SD Pro App to delete cache files occasionally but that was getting to be a tedious every day task.
Right now I at about 240-330 free of 750. About 70 MB seems to be stuff the Google Play Store caches so I have to clear that occasionally.
One thing I wonder if people are keeping track of-the Dinc and alot of older Android devices have only 512 mb of RAM. Some are worse and only 256mb. Installing programs even if not in use seems to load the programs in memory. if the memory manager does not kill these efficiently, you might get slow to sluggish behaviour. I am running OS Monitor on my phones and it does report that I have only about 45 mb of RAM free. the worst seems to happen when you are switching between apps alot-I think it;s possible for a 2nd or 3rd instance of a program to get loaded in memory temporarily. So I have removed as much from my installation as possible-stuff that should be benign like GMAIL just to prevent it from loading.
I don;t know any of this to be a fact though, I am just an end user sharing my experience.
Just an update on storage space issues, I recently installed a bunch of apps that had to reside in the phone memory. Checked in App2sd and it said I consumed about 600 of the 749 mb. I uninstalled the unnecessary stuff and cleared the cache. So I am sitting on 280 mb free now.
Without the low space fix ext4 mod, this would have been a FATAL situation resulting in a boot loop and needing a complete wipe and reset.

[Q] Anyone know why my data/data folder keeps freaking out?

Was getting low storage error and moved a bunch of apps to sd card and my data/data folder showed I had like 80mb free and error went away. Couple days later error came back without adding any new apps and I was under 15mb free, figured this was weird and restarted my phone and it went back to 78mb free.
So what could cause this? Is something not clearing out right here on its own? Btw I am on a stock deodexed rom.
if you don;t install the EXT4 fix, the stock configuration is for the Data partition to be a paltry 149 mb. That can get filled up pretty quickly-mostly by apps like the messaging app, Google Maps and anything else that needs to stored data in this "high performance/secure" location. i put it in quotes because it;s the "official reason" for doing this but I think it;s crap. in reality it;s a design flaw by HTC that never got fixed. also, files from the Playstore get cached to this partion which is why the free space available can jump up and down. there is only so much moving apps to SD Card will fix. the problem is certain apps accumulate data over time.
If you do install it you will have 749 mb available. if you have a rooted Dinc, I think there is no reason not to install it. then again I am not certain if your ROM is compatible. I hear that Touch of Blue has this fix integrated into it if you want to stay on Gingerbread.
this thread probably has all the info you need

Thnaks man but it's not that, something is just "wrong" with it lol.
It will say I have close to 80mb free and just a few hours later be full. I noticed If I go into Titanium Backup and do some stuff (like removing orphan data) or something it seems to fix it and the low on storage space error goes away and frees up like 60-70mb instantly. This never used to be like this.
Wonder if it's just a sign of an aging cpu or phone not calculating how much free space is there properly.
did you install the fix? if you did not, then do it. the Dinc is a very well known device. Us users have beaten this device to death over the last 3 years. there is not too much new going on. it could be possible that your device is failing and if it is, get a new one.
before I rooted my Dinc, it was a daily struggle for me to keep this partition from filling up. for me the combo of data being consumed by Amazon App store, Google Play store and mostly my email client with 4 email accounts. 149 mb is just too small.

Not enough room to update apps?

Hi guys, in the last few months a strange problem has started appearing on my n7100 with 4.1.1.
It won't update apps, often when the apps are 20 mb+, but it happens with smaller apps too. It says there's not enough room on the device, but the whole time I've had around half a gigabyte on the internal memory, so I can't see what the problem is. Right now it says I have 660 mb free on internal, and 1.35 GB on the sd card.
Sometimes it has helped deleting some apps, but the problem comes back.
Any ideas?

You need like around 500 MB for your other apps to work .. Some apps will write and put files in your internal storage so they can function properly .. You have to delete some of your internal storage ..
You can't put apps in your External SDCard (unless you use some of the apps that makes it do that)..
BTW, update to 4.1.2 it might be the problem
Sent from my GT-N7100
That seems a bit ridiculous to me, when already the effective space is 10.36 GB. I would think that the space it needs to perform, was included in that. My old Htc desire was able to fill up till the memory ran out (which admittedly was very quickly).
No no, I know that, just wanted to give a detailed overview.
I would update, but with all those battery consumption problems I've been hearing about, I'm waiting for the next update, and then I'll see what people are saying.
