I'm sure many people like me are aware and annoyed by the extremely limited amount of RAM in Nexus S (512MB but only 300+ is usable), I have searched all over google for a solution to increase the amount of RAM available and came up empty (I tried swap file applications but they just broke my system's SD card partitions causing a complete reset).  I wonder if there is any hardware solution to this problem. Is it possible to swap the chip out for a bigger capacity one? I realize that it is not as simple as swapping out PC RAM from a dimm but I haven't seen any schematics for the chip layout on the ARM boards in the smartphones so I really hope that it is somewhat possible to increase the amount of RAM on the board.

Currently, my internal storage is running low on space.    What can I do besides moving applications to the external memory, as to free up more space, but preserve my current applications and avoid uninstalling?  (Some of them won't be moved)

Is there any method for using Android applications on a computer, because I found  tutorial but my laptop just has 1 GB of RAM and works very hard. I want to use WeChat on my PC because I like it very much.

I would like to know whether there is a way to tell Android to install applications on the micro SD card by default instead of having to download applications to internal memory first and then having to move them to the SD card manually.  Thanks

I ran into something a couple of weeks ago that I'd never seen before: A filesystem (ext3 I believe) installed to a storage device without a partition. In essence /dev/sdb was the entire filesystem. I know many filesystems can be extended into empty space, so doing this allows extending without dealing with LVM or some other kind of volume manager, but are there any other advantages for setting up storage this way?  The specific case I saw was as the ephemeral data volume for a number crunching server, the boot and root volumes were traditional partitions on a different storage device entirely. -

I am following this tutorial for moving apps to sd card.    But My Default Location is not changing. And My Phone Memory is full and unable to install new apps.

What are the possible difficulties occur if I use external SD card using Format as internal storage ? I have checked this link:   Here are some doubts:    Does internal storage space increase, if no why? Whether any memory problems with TWRP, Titanium backup? What to should I do, If I need to switch with another SD card as external OR restore to earlier? What will happen, If I accidentally boot device without SD card? What to do after upgrade? (upgrading to higher android versions OR to lower android versions ) Will this action improves performance?

I have an Ubuntu virtual machine running in VirtualBox 2.2.4, and I created it on an 8gb virtual disk which is too small.  So, I am trying to increase the size of the disk.  So far, I have done this:   Created a new larger virtual disk Added the 2nd disk to the machine Used CloneZilla to clone the first disk onto the 2nd disk Removed the first disk Booted up off the 2nd (larger disk)   But now I'm still stuck with an 8gb partition on my new 100gb virtual disk.  Whats the easiest path from here to having a 100gb partition? :) I gather GPart can resize partitions, but it doesn't seem to support LVM2 partitions, which mine seems to be.  thx   Alex

I have a 16 GB Samsung Galaxy S3 phone - 5.05GB of which is being taken up by thumbnails! Can I move these to my 32GB SD card?   I have tried DMR (duplicate media remover) and that has detected duplicate pics and videos but stops when I try to delete them.

I try to run Android from SD-card. This card is prepared. There are partitions: boot(FAT32), rootfs(ext4), system(ext4), cache(ext4) and usedata(ext4). Boot partitions has files to run u-boot: MLO, u-boot.bin and uImage. To run it I use commands  mmcinit 0 fatload mmc 0 0x80000000 uImage setenv bootargs 'console=ttyO2,115200n8 mem=456M@0x80000000 mem=512M@0xA0000000 init=/init vram=10M omapfb.vram=0:4M androidboot.console=ttyO2 root=/dev/mmcblk1p2 rw rootwait rootfstype=ext4' bootm 0x80000000   Than I see how Linux starts. But after few seconds on step of loading rootfs I see an error message  [    4.015655] EXT4-fs (mmcblk1p2): couldn't mount RDWR because of unsupported optional features (400) [    4.036499] sd 0:0:0:0: [sda] Attached SCSI removable disk [    4.079986] List of all partitions: [    4.083801] b300        31162368 mmcblk0  driver: mmcblk [    4.089660]   b301             128 mmcblk0p1 f9f21f00-a8d4-5f0e-9746-594869aec34e [    4.097839]   b302             256 mmcblk0p2 f9f21f01-a8d4-5f0e-9746-594869aec34e [    4.106018]   b303             128 mmcblk0p3 f9f21f02-a8d4-5f0e-9746-594869aec34e [    4.114288]   b304           16384 mmcblk0p4 f9f21f03-a8d4-5f0e-9746-594869aec34e [    4.122436]   b305              16 mmcblk0p5 f9f21f04-a8d4-5f0e-9746-594869aec34e [    4.130676]   b306            8192 mmcblk0p6 f9f21f05-a8d4-5f0e-9746-594869aec34e [    4.138916]   b307            8192 mmcblk0p7 f9f21f06-a8d4-5f0e-9746-594869aec34e [    4.147094]   103:00000     524288 mmcblk0p8 f9f21f07-a8d4-5f0e-9746-594869aec34e [    4.155334]   103:00001     262144 mmcblk0p9 f9f21f08-a8d4-5f0e-9746-594869aec34e [    4.163574]   103:00002   30342128 mmcblk0p10 f9f21f09-a8d4-5f0e-9746-594869aec34e [    4.171874] b310            2048 mmcblk0boot1  (driver?)

is known as a “systemless” root method. It’s essentially a way to modify the system without actually modifying it. Modifications are stored safely in the boot partition instead of modifying the real system files.   I have looked around but did not find a sufficient explanation as to how it actually works. How is the root access gained and maintained? What exactly is the role of the boot partition and if it integrates with the system partition how it does it? A really detailed description of how it works lacks from everywhere I searched so it would be really highly appreciated.

Construct an 8k X 32 ROM using 2k X 8 ROM chips and any additional  required components.  Show how the address and data lines of the constructed 8k X 32 ROM are  connected to the 2k X 8 chips.  I tried to solve it but I am not sure if I got the correct answer. Could anyone check my drawing and correct me?

Is there any way that I intentionally grant root permission to some app? Not automatically via SuperSU when a specific app asks for root permission, but in a way to pick an app via some tool and grant it root permissions.   For example, I add my favourite text app to the approved list and then I can open root files via that app.

If I want to add more RAM to my computer, how can I buy something compatible? What kinds are there? How do I determine which kind my computer will accept and how much I can add?

Background:    I put in a friend's SD Card to format it because it was having problems. Then I put mine back in and I think my phone formatted my SD Card. I had a ton of pictures on there that are now gone! I put the card into the computer and there's only 2mb of cache files on there and none of the original directories.   I already tried the following freeware recovery applications:         Neither of them were able to retrieve any files. Undelete took 1minute to scan for files and came up with 0 files.  Recuva took 10 minutes for their "deep scan" which doesn't seem thorough enough at all for this 8GB SD Card. I need something that's a lot more heavy duty.  I don't mind paying for an application to get the data back if necessary...   Questions:     Which application can I use to recover my deleted picture files from my 8GB HD Micro SD Card?   Why did Anroid format my SD card?   How can I tell if it's a phone problem, data problem, or SD Card problem?

After upgrade of any app - apps move back from SD Card to phone memory.  After that, to save phone memory, I have to move upgraded app back to SD card.   Is any possibility to avoid this because it is very annoying?  I have Android 5.0.2 on Motorola E second gen phone.

One of the main advantage of rooting is removing bloatware [I guess]. Is removing unwanted brand-based or operator-based app any different from disabling it from All Application in Settings? I don't find any improvement in memory too since these apps were pre-loaded in OS and you can't use those space any way.
