I understand the Prime has a quad-core processor, along with the fifth primary core. I also know it has 1GB of RAM.
My question is this, whenever I'm downloading multiple torrents, I can barely use any other applications. Everything is slow or stops responding, then just force closes, or reboots.
Is this normal? With this much processing power, I thought the Prime would be able to handle multiple torrents and app usage. Am I wrong?
Mine does the same thing. Its so annoying that I can barely do anything if I'm downloading a torrent. What torrent program are u using? I'm using aDownloader
I'm using aTorrent. I haven't tried any other ones, but now I might just to see if it's the app causing the system to slow down to a halt/crash.
Yeah that's why I asked. If you were using the same app as I was then I would be suspicious of the app but we are using different programs so I doubt its the cause.
Yes prime does have 1gb of memory BUT only like 500-650mb or so is available to use for apps n multitasking. The rest is being used by Android OS itself to run system processes.
well when downloading large files like movies which i bet you are it takes a lot of resources!
Downloading multi torrents your maxing out the read and write if the internal memory causing everything to slow down to a crawl. Has nothing to do with the CPU.
Thanks for the clarification! Does make me feel better that it's not an issue with my Prime. At the end of the day, I'm still happy that I can even download torrents directly to my Prime.

QFT...if you're able to, save to the SD card rather than internal storage

Are you referring to an external micro sd? I'm only asking because the internal storage on the Prime is named SD Card.

How much memory do you guys generally see as "available" when you first start up your phone. I generally have 160-180mb of supposedly "used" memory. This is after a root and almost all possible bloatware being removed. Normally I would just figure it'll be freed up when I need it but I have had such issues playing Dungeon Defenders which is memory intensive. Sometimes it plays smooth as a champ, other times it stutters a lot. Other times it freezes during load times.
So is all that memory available and it'll just free it when it needs it? Or is that number unusually high?
Oh also my comic book viewer will force close sometimes on some images, even with its options set to use less memory, and I don't think it takes hundreds of MB of ram to open a zipped 500kb image. Then again I could be wrong.
Memory is used differently on Android than on your PC. Just because you have 100+ megabytes of available memory doesn't mean an application can use all of it. Each app has a hard limit of how much RAM it can use, which I believe is around 16mb but differs from device to device.
If you experience issues when running a game I would check to see what background services are running at the time that could be using up CPU cycles.
Hi when I download highspeed content from the browser or download torrents to the prime, is unusable, and often stop responding until the download is done.
It dont even need to be faster then 500kbp for this to happen, so it seams to me that it is a problem with the disk speed, dose any one else have this problem, and do any one know why this happens?
The internal memory in the prime, cant possibly be that slow?
There is an I/O issue for the Prime. It appears to be a software issue and not hardware (good news!). So, the best solution to do, is download those files directly to a micro sd or regular SDXC card for the keyboard.
For example, if I download a large torrent using aTorrent to the internal flash memory, my Prime becomes extremely unresponsive. If I download the file to external storage, it will not slow down the system.
Hopefully this will be fixed soon. With the new .13 update, flash memory (there is no disk) performance is up as well.
After googling and searching alot, i didnt find my answer
so hope someone can help me here, and this will help others too.
so install apps on SD Card or Internal memory ?
The internal phone memory is generally of a lesser amount than the amount of the memory you'd have on a SD card. You cannot really change the amount of internal memory you have on your phone but you can always get a new SD card with a larger storage capacity.
So when you have apps that need a lot of space it is better to have them installed on the SD card.
will installing more apps on internal memory make the phone run slower ???
I don't think it will make the phone run slower, but you'll have lesser storage space for your other data which is stored in the internal storage like your contacts etc.
i have an HTC Sensation XE running on Darkforest ROM, this is my RAM (pic) how can i increase the free memory, thats the max i get around 180MB free
View attachment 1034360
Can I know why you wish to free up the RAM? In most cases you really don't need to because the OS manages that quite efficiently. It will free up the RAM and make room for the running applications whenever it needs to.
cuz in some apps after opening them for a while and try to close this app the phone restarts, so i read that its cuz of low RAM
please correct me if am mistaken
180 mb is a lot of RAM for a single application to use. And as I said, the OS, is pretty good at managing it. Although I cannot exactly tell you why your phone might be restarting when you close some apps, I don't really think it would be cause of the low RAM.
I checked my phone and it had about the same amount of RAM occupied as yours(i.e. 2 thirds of the total capacity). Then i started a game called Fruit Ninja which uses 3d graphics, which should need a lot of RAM. Then i pressed home and checked the RAM usage again. Even then the RAM usage did not go up by much.
You should try to verify this on your phone too. Check the amount of RAM thats being used. Then start the application thats causing the problem. Press the home button and check the RAM usage again.
An app will probably run quicker from internal mem because flash storage is much slower, but youre'e limited by space constraints.

Well it might load into the RAM quicker. But I don't really think there is much of a difference in speed while its running. Unless there are a lot of loading and writing operations.
Pay attention to one thing: internal storage and ram are not the same thing.
Ram is commonly allocated on a high speed journaled partition and it is 1000 times or more faster than both the internal emmc or the external SD (that'd why a swap partition is not as fast as real ram).
Just for the I/O parallelism, an app installed on the external sd could very likely run faster than one that resides in the internal emmc. Anyway, it also depends on the class of the external sd, though the class counts only when writing sequential data, while reading could even be faster when using a lower class SD.

Doesn't an application get loaded into the RAM first when its started? So would its execution speed still depend on the sd/internal memory?
I thought that would come into the picture only when theres some kind of read/write thats happening to the sd/internal memory...
Well, if it is true that any app run inside the dalvik vm and such vm is able to run simultaneously multiple apps in its sandbox, I suppose that any app could need to access its installation files and its stored data while running.... I am not sure, anyway, it is just what I believe it could be.
To be true, my supposition mostly derives from what I've experienced with chrooted linux, which run faster when the .img file is stored on the external sd.
Anyway, if it should be as you say, the app's speed would be totally independent from the support where it was installed.

That is what I exactly meant. Although it differs from case to case, an application typically loads all the stored data it needs at the start. And then throughout the execution of this application, loading/saving of data is generally rare.
Of course this is a very generalized statement and such things are handled differently by different applications depending on how they were implemented and what they are intended to do.
Consider for example a game. The game would load all the textures, images, music it would need for a particular level. Then throughout the entire period of the level the game wouldn't need to load any data. It is only when some different support data would be needed by the game, or if the player's state is to be saved there would be a read/write operation. At such a time only would there be a need to access the sd/internal memory. So it really doesn't make the difference of where the game is installed very noticable.
Now on the other hand if you have an application say an Image viewer application which loads an image from the the sd/internal memory every time the "next" button is pressed. Then, maybe you'd have a noticable difference based on where the image is being loaded from. But even typical image viewers implement some sort of image caching to reduce such excessive loading.
Widgets
I had a problem where apps that used a widget option did, not give that feature anymore when the app is moved to the SD card...
Hey guys,
My phone was quite fast and responsive when i first bought it. But now aftre 9 months of use i have found that it has slowed down. I shifted from GB to ICS but that hasnt made any difference. The load up of contacts takes especially long.
I was woundering if like in computers we defragment the HD do we need to do the same on phones ocasionaly.
Please let me know if there are apps for this or any solutions.
If u do this u can break ur phone

if your device has become slow, you might want to think about performing a wipe / factory reset every once in a while. also, delete contents from your sd card, apart from music, videos and pictures.
defragmenting from a pc won't help, but also won't break your phone.
The filesystem that Android uses doesn't fragment like Windows' one does, therefore defragmentation isn't possible. You could try clearing up some space though. E.g. deleting apps, music, photos etc.

do like mine..
You can download DX Tools Optimizer from Playstore
It's free & has all of the answers of your asking about..
Go thru w/ it & u'll find much fun tools u'll need..
But don't forget to press thanks...

only half true. sure, the filesystem on the system partitions can not be defragmented, but they are not directly accessible from a windows pc anyways, i believe the op was talking about /sdcard/ and the external_sd/ or /emmc/, which usually are formatted in fat32 and can be defragmented. if he copied several things simultaneously, it might even be fragmented.
Check the free space available on the internal sdcard - my Wife's GSII had a similar problem where it would almost grind to a halt. It turned out the sdcard was full, and transferring the photos/videos off the 'phone returned performance to normal.
Thnks all. I think they are good suggetions and i will try them out and let you know the result.
Hi everyone. Sorry for starting a new post, but I looked and I wasn't sure where my question fit in. I'm using Link2SD on my kids' tablets and overall it works great. I got really fast (SanDisk extreme) micro SD cards for black Friday and the games run faster than with tablet memory. One thing I'm trying to figure out is why, even though I have both tablets set up mostly the same, one of the tablets has a lot less free space showing. I do have about 400-500 MB more of apps on the tablet showing less free space, BUT it is showing 4.0 GB free space vs. 5.8 GB free space on the other tablet. Why would this be (1.8 GB difference) if all else is the same?
Is it something to do with dalvik/cache? Speaking of it, is it safe to wipe the dalvik/cache through TWRP now that I have Link2SD set up with 30+ apps linked? Do I then just relink the dalvik files after rebooting? Or do things get messed up? I'm hesitant to do any of that because I have everything working well now, except the free space issue.
Or, if I multi-select and then choose to relink everything (apk, dex, internal data), could that help? Everything appears to already be linked correctly, so would relinking mess it up? Also, as a side note, I don't have any lib files linked as I have found that in the past it did mess things up for me. It would cause some apps to re-optimize at every boot, I think because the lib files wouldn't relink, even though I enabled it in the Link2SD settings. So now I stay away from that and all else is good, except this free space issue.
Any ideas on a solution? Is there something else taking up free space that's not listed in internal or system memory? Maybe downloaded Google play books? Or are they listed in the app data? Is the free space shown not correct, and it's actually more? I just can't figure it out. Any ideas would be great. Thanks!!!!
Here are the screenshots. You can see 5.76GB vs 4.07GB, but only 6.94GB vs 7.34GB for internal space difference. Why?
