Rom Size worries

Need some reassurance...The Internal MB free is the space I need to worry about as the phone uses this as its memory. I have a few apps installed already, but was curious if I need to worry about the system Rom size.
Mine Reads:
System Rom: 367MB (9.94 MB free) (Kingsrom R 6.1)
Internal : 448 (323 MB free)
SD Card: 15.9 GB (10.2 GB Free)

Your running kings from it takes up slot of space if you want space flash another rom hehe

The Internal space is what the Apps are installed to anyway correct?

Do a search for APS2SD.
It's very simple to partition your SDCard so you can run that.
Here's a good guide:

Unless you're adjusting your partition sizes (which I believe most people don't do), it really doesn't matter how big or small the ROM itself is, as long as it fits. It goes on a separate partition (/system), which is a fixed size. With few if any exceptions, files don't get written to /system during daily use of the ROM. Your apps and data get installed to /data, which is also a fixed size partition. Having space free in one doesn't help you with the other. So the extra data in /system just sits there unused.
There are ways you can adjust the partition size, but I think there are some downsides to doing that -- I don't know off the top of my head what, but there must be a reason it hasn't broadly caught on. You can also manually move apps into /system, but if they get updated you have to remember to move the updates back again.

Internal flash size

Does anyone know why our reported internal flash size is only 2GB when the phone is advertised with 4GB?
'dmesg' output:
Code:
mmcblk0: mmc0:0001 SEM04G 2.28 GiB
system+data+cache along with other smaller partitions roughly add up to this figure.
hboot and radio are roughly 25MB and 1MB respectively in size.
I found this which would mean the capacity is halved for better reliability, but in that case I don't think they should advertise it as 4GB internal storage phone...

1st wrong section
and why ua worried about their advt?
it's probably a marketing strategy i think
and obviously there has to be a reason gr this
some of the storage is used by Android os

If this is wrong section I apologize, mod please move it to the correct forum.
The android partitions are usually (sorted by size):
system
data
cache
recovery
boot
misc
The lower levels of the phone usually use (normally hidden from android):
bootloader (hboot)
radio
other proprietary stuff
Feel free to check partition sizes on any android phone.
My previous devices were HTC Desire (bravo) and HTC Aria (liberty) which both had 512MB nand chips and my point is that I expected much more space available to the user (me) from a 4GB phone, knowing how much space android takes. If it was at least reserved for future use (bigger ROMs etc.), I'd accept that, but not just halved like this.
"some of the storage is used by Android os" is true, Android OS uses ~980 MB on system partition on my stock ROM (a load of bloat/features ). You have about 1GB free on data partition. The remaining 2GB is missing (i.e. we have 2GB internal storage phones).

[MOD][TWRP][RECOVERY] Reclaim the whole free space of your system partition

Hello,
many users complain that since lollipop their system partition size doesn't reflect the actual system of the block device. Therefore, they can not install some extra in this partition( busybox, big gapps packages,etc.).
This is due to the system image size specified when building the rom:
One of the parameter of your system partition(which has been hardcoded in some config file, I.e. BoardConfig) is its size, but if the block device(i.e. the part of your internal storage that will be mounted for the system partition)'s size that is mounted is larger than the system partition's size than you will loose some space.
TWRP has included this feature into their recovery from 2.8.7.0 and onwards ! You don't need to get my flashable package if you got a newer version than this.​
Fortunately resize2fs executable allows to modify an ext2,ext3,ext4 partition size:
linux man page said:
The resize2fs program will resize ext2, ext3, or ext4 file systems. It can be used to enlarge or shrink an unmounted file system located on device. If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel supports on-line resizing. (As of this writing, the Linux 2.6 kernel supports on-line resize for filesystems mounted using ext3 only.).

This package simply resizes your system size to match the size of your block device size.
It does not alter your partitions table just reclaim the unmounted space.
Instructions:
Boot on a twrp 2.8.x.y TWRP recovery
flash the package

Lets see if I understood this correctly. Currently in Lollipop the system partition is smaller than the block where the partition resides? And if the partition size doesn't match the block size, you will loose the remaining space on the block? The remaining space on the block is not available to any other partition?

That's correct. Your system partition is mounted with am 800 mb allocated space. Depending on your ROM ypou might loose some space.
Here I got 437 mb of free space .

Tried it and my system partition went from 643.7MB to 787.9MB in size on Lollipopalooza. That definetily helps with installing gapps as last time I had to leave off quite a few apps to get it to fit. So just to make sure, this extra space isn't taken from any other partition? It just made the system partition use the unallocated free space on the block?

Which app do you use to see partition sizes? How can I see what it is vs what it should be? Thanks.

Exactly.it corrects some internal ext4's variables that represents the size of fs to match the block's

There are plenty out there . I use fx embedded filesystem's analysis

Excellent! I have one more question. As we know, modifying the system partition means that otas will fail. So if before I had to uninstall say Play Movies to make room for busybox, then I'd have had to reinstall it if I wanted to flash an OTA. With this method, the md5 signature of system isn't altered, and therefore otas wont fail, right?

You are on aosp ?

Best way is either issue
df in a terminal console or install this app

It will display the actual filesystem size .disk info display the size of your ssd

Thank you very much for your mod.
I want to try it but I'm a little bit afraid. Do I lose any data? Will this affect the installation of other ROMs? I'm on stock now but I want to try some custom ROMs to decide. Do I have to use your mod every time I install a new ROM?
Thanks in advance!

You won't loose any data it will adjust the size of ext4 fs to the actual physical size of your partition.
Flashing a new lollipop ROM flashes a new system image which specifies the image size.
Our device system image size is defined here https://github.com/CyanogenMod/android_device_samsung_manta/blob/cm-12.0/BoardConfig.mk#L64
685768704 is 654 megabyte but your mmcblk0p8 partition mounted on /system is 800 mb.
Until this is fixed. Will open a ticket to increase this value but there are maybe few reason google chose 654.
And yes you must reflash it each to flash

If you replying to my question then I didn't do anything. I'm asking I should do it.
Is this only for CM based roms?
Thanks

I installed the app you said, but I didn't see any unclaimed space. Is your mod for stock ROM as well? I seem to have 644MB of space on the /system partition.

Well the maximum space you system partition can get is 800mb. The system of je partition number 8.
Thus you are looking space.
The resizes just fixes that

Yes, if your system partition is already 800MB in size then you're already using the whole block.

Partition resizing

I have 1.8GB of free space on my SYSTEM partition. Is there any way to shred that down so I can have more space on my DATA partition?
I'm running cm12.1 on my t805

As far as I know it is not possible because system partition size is fixed in source of the ROM. Theoretically it could be done but I am not sure if custom recovery also needs to be customised like ROM? I think best solution would be to buy large sdcard (64GB) ?

It is somewhat possible to resize partitions by adjusting the parameters in the pit file.
However how risky this is for the sake of what, 1.5gb, I don't know?
The better option, if you don't want to waste that space, is to use it.
Move your apps from user to system apps.
Its easy enough to do and can be accomplished with little effort using apps already available and with the bonus of gaining the extra space on the data partition.

Thanks guys. I just moved some of my bigger apps to system partition.

[Question] Resizing partitions with TWRP

I have a brand new G3 (D852) with Koodo that I just got 2 days ago. I've rooted, installed TWRP and flashed a few AOSP roms. Not a fan of any manufacturer UI, even though LG's is very minimal, so AOSP it is. I noticed that my system partition has more than 1GB of free space after everything is flashed and good to go. I also noticed that the latest TWRP (2.8.7.0) has a resize partition option inside the Wipe section. What I want to know is, how can I use this to resize the system and data partitions so that 1GB+ isn't being wasted and unused. I'd really like to get that 1GB+ added to my data partition for apps.
I've tried using it. The only time it didn't spit out an error was after I wiped the system partition. It succeeded in "resizing" it after that, but it didn't change anything. The system partition remained the same size.

This it why the option is there:
resize2fs feature: On some devices like the Nexus 6, the factory images include a userdata image that is the proper size only for the 32GB units. If you flash the factory image to a 64GB Nexus 6, the data partition will appear as if it only has the free space of a 32GB device. Using the resize2fs option, TWRP can resize your data partition to take up the full space available. The resize2fs may also be useful to resize system partitions on devices where custom ROM system images don’t take up the full partition space. Lastly, resize2fs may be useful in some cases to reserve the proper space at the end of a data partition for a full disk encryption key, should your partition be formatted incorrectly for some reason.

Thank you for the reply
If I understand you correctly, the feature's original intent is to resize /data partitions in the event the rom/system image treats a larger storage capacity device as a lower capacity one, ie. 64GB device is treated like 32GB so /data will only reflect 32GB minus (system image install size), wasting 32GB and leaving it inaccessible to the user.
However, it also seemed like you were saying I also could use it to resize my /system partition to a smaller size so CM12.1 (with it's ~900MB install size after Full TK-Gapps) will only leave ~50MB to ~100MB on /system instead of ~1.5GB. However, the question remains. How do I do this and can I reallocate the ~1.5GB to the /data partition for apps and internal storage? If this can't be done then I see no point in resizing /system to begin with as it will still be inaccessible to me as the user.

I read a few things online and it seems you need aan unlocked bootlader, the G3 bootloader is not unlockable, so you are probily out of luck maby you can ask in the Q&A thread of the rom you are using.
