I find it hard to believe a quad core cpu with each core capable of 1.9ghz struggles to cope with the resolution.

Blimey I've got way lesser powered desktops that don't have issues with such resolutions.

Tbh I don't have issues, but I know some do. Personally I think the lag comes from the big-little core implementation.

If it was just a straight quad core cpu then I think the performance would be much better at the expense of a little less battery time.
[Galaxy Tab S General] meduza:
[MENTION=4899305]ashyx[/MENTION] ,

I`m happy to read you feel a similar way :)

Btw. there are two different but very similar CPUs on the tab S, US end EU tab s versions have different CPUs. Maybe the reason for the lags can be find here... .

[Galaxy Tab S General] zavien3:
I guess it's all in the eye of the beholder. There's never been anything smooth in my experience with the Tab S. I've owned probably 20 different tablets from the HP Touchpad to the Tab Pro. This Tab S is quirky. I'm thinking maybe the Tab S in my hands doesn't perform because its still upset Samsung chose to make it golden diarrhea color.

I`m on f2fs now but can't really feel a performance improvement... . On my s3 mini and the retiered liberty tab one could really feel it after covering...

I am thinking of trying F2FS. I have a T700 running rooted stock (5.02) and the SkyHigh kernel (which is F2FS compatible). If I try F2FS, do I need to reflash the kernel, or clear cache, or do something else? Thanks!
[Galaxy Tab S General] meduza:
I was on SLIM when I converted. Formatted data & cache to f2fs, restored backup of data, that's it. Didn't reflash ROM or kernel... .

[MENTION=4662107]meduza2[/MENTION]: For some reaaon, the XDA app isn't letting me thank you or quote your post. I get "invalid thread ID". Never saw that before.

Thanks for your reply. I'll try it out when I have the chance. Other people have had very different experiences with F2FS, it seems. I'm curious to see what mine will be.
[Galaxy Tab S General] meduza:
...don't worry m8 ;)

I'm happy with f2fs since ART was available on KitKat... .

[Galaxy Tab S General] UpInTheAir:
Following this guide,.... and after restore your data in step #4 , I would advise to wipe at least dalvik-cache partition so SkyHigh kernel will re-optimize ART during next boot. Otherwise re-flash kernel and the updater-script will do it for you.
[Galaxy Tab S General] Windsor1959:
Thanks! I'll probably try it out this evening.

BTW, I'm really pleased with your kernel so far. I'll be on a learning curve for a while, but that's okay!
[Galaxy Tab S General] Windsor1959:
I did the F2FS conversion according to the instructions in the OP. All is well. My Tab S seems to boot faster, but I don't see a difference in how apps run. Now, I had frozen some bloatware and saw a performance bump from that. That could be one reason why I don't see a change here. I'll see how things go over time.

Thanks to everyone who helped!

Just flashed it myself on my T700, running IronRom V.2.1. Had to use latest kernel for it to boot, but otherwise, everything else seems fine so far.
[Galaxy Tab S General] corb06:
Unable to backup to SD-card... anyone else getting this error??
[Galaxy Tab S General] ashyx:
This is totally irrelevant to this thread.

If you need help with twrp you need to post in the relevant thread.

Your issue is likely your sdcard.
[Galaxy Tab S General] dapat:
Ashyx, is it ok also to covert the external sd card to f2fs once data and cache partition have already been converted? Thanxx.....
[Galaxy Tab S General] ashyx:
I wouldn't, there wouldn't be any benefit. The sdcard is basically storage only and not subject to constant r/wr operations. Not only that it may become invisible to the os and apps as the sdcard is mounted under the fuse file system.

Plus the kernel would need it's mount points modified to support it.
[Galaxy Tab S General] dapat:
Thanks for the info.
[Galaxy Tab S General] jalchemyst:
Does this process only change the rom? So if I switch roms or update, will I need to go through this process again? Or is the change permanent?
[Galaxy Tab S General] ashyx:
It clearly states in the first post only cache and data are converted and ANY rom can be used. :banghead:

The changes are permanent unless you reformat or you flash a ROM which does it.
[Galaxy Tab S General] dapat:
Ashyx, just for curiosity. What about if the 3 partitions are f2fs supported as a particular rom is intended for, e.g. cache, data, and sytem? Is it still not beneficial to make system partition f2fs even if a developer intends the system partition in his rom to be in f2fs along with the cache and data?

Thanxx....
[Galaxy Tab S General] ashyx:
There is absolutely no point at all in the system partition being f2fs.

The benefit of f2fs is its superior write speed. The read speed is on par with ext4. Seeing as the system partition is read only there is no benefit, in fact it's safer for the system partition to remain ext4 because it's a journaling file system and less prone to read write errors.

Its easy to recover a data partition that has corrupted than a system partition.

If the system partition gets corrupted you could easily find yourself in a no boot situation.
[Galaxy Tab S General] dapat:
Thank u so much ashyx for the info.....Thumbs up.
[Galaxy Tab S General] dapat:
Thank u ashyx for this guide I have converted to f2fs my t805 cache and data partitions.

I have here another Samsung galaxy note device in custom ROM. Now I want to clarify whether I can also convert its cache and data partitions . I have here twrp and kernel that support f2fs ready for flashing intended for my galaxy note device. To be clear, the ROM installed in my galaxy note does not support f2fs (data and cache partitions).

Now my query is: Can I convert cache and data partitions in my galaxy note with the help of flashing the kernel and and twrp which support f2fs? Is this what you imply in the op that any ROM's cache and data partitions can be converted to f2fs as long the kernel supports f2fs.

Thanks a lot!
[Galaxy Tab S General] ashyx:
If you have twrp that supports f2fs then all you need is a kernel that supports f2fs.

It doesnt matter about the rom as that will remain untouched.
[Galaxy Tab S General] dapat:
That's it...that's what I want to confirm. Thank u ashyx. You know what, you have been so instrumental in my journey to android ROMs from rooting my t805 with your autoroot to instructions on twrp. Hoping that you will still help more especially those who are newbies in the android world. You truly are a gem in the XDA community. ???
[Galaxy Tab S General] LazyT:
How the partitions are mounted when cache/data is only ext4 in fstab?
[Galaxy Tab S General] ashyx:
You have to add f2fs.
[Galaxy Tab S General] LazyT:
Exactly, and therefore your statement is dangerous - rom will not boot without this.

Just to warn people to check fstab first. Not every rom has dual entries for ext4 and f2fs... ;)
[Galaxy Tab S General] ashyx:
Are you purposely being facetious or what? :o
[Galaxy Tab S General] adroit_y2k:
Hello ashyx..changed the file system and loving it with the power rom on my t705!!

Speed and performance improved significantly!!

Thanking you!!

@ashyx can You write steps to add F2FS filesytem to an existing kernel?
[Galaxy Tab S General] glennza:
Does anyone know if LineageOS supports f2fs?

Otherwise, I would also like to know how to manually add it to an existing kernel
[Galaxy Tab S General] bluess57:
f2fs is a kernel feature , not specifically LineageOS.

The exynos5420 kernels built /using source from https://github.com/exynos5420/android_kernel_samsung_exynos5420

will have f2fs enabled (unless the builder turned it off).

The kernel needs to be built with f2fs support enabled,

i.e. your kernel config file, needs to enable (or have enabled) the F2FS configs

eg.

CONFIG_F2FS_FS=y

CONFIG_F2FS_STAT_FS=y

CONFIG_F2FS_FS_XATTR=y

# CONFIG_F2FS_FS_POSIX_ACL is not set

CONFIG_F2FS_FS_SECURITY=y

# CONFIG_F2FS_CHECK_FS is not set

# CONFIG_F2FS_FAULT_INJECTION is not set

CONFIG_FS_POSIX_ACL=y

The fstab needs to have/be modified to mount the partitions as f2fs

eg.

/dev/block/platform/dw_mmc.0/by-name/CACHE /cache f2fs noatime,nosuid,nodev,nodiratime,inline_xattr,inline_data,data_flush wait,check

/dev/block/platform/dw_mmc.0/by-name/USERDATA /data f2fs noatime,nosuid,nodev,nodiratime,inline_xattr,inline_data,data_flush wait,check,encryptable=footer,length=-16384,reservedsize=128M

Again the exynos5420 sources of branch 18.1 will have this, see->

hey folks. Samsung G3 d2tmo device running CM12.1 6/20/15 Nightly. i have been using CM for a while and i like it. i especially like the integrated blacklist. i am wondering if anyone has found the location of the data file, the list of numbers? i tend to try to keep up with Nightlies which means i also tend to wipe data and reflash from time to time. the 35 or so entries are a bit of a pain to re-enter. not critical, i love the work that has gone into CM and i love the way i dont HAVE to add google apps if i dont want to. also the dark material theme is great and life is good. i just wish i could find that file and back it up. while we are at it, the config data for all my email accounts would be great to back up also... hmmm...

anyway, any leads, let me know.

thanks

Still trying to find blacklist

I appreciate the lead. I went looking for it and did indeed find a blacklist file. Unfortunately it was 137 bytes of some other encoding, so unverified as my list of numbers.

I suppose, if I believe that this is the numbers, I could back this file up and stick it in place if I have to reflash a ROM. I'll copy the file for now and see how that works.

Thanks for the help. Any further ideas about how to confirm its a list of phone numbers, what the encoding might be, I would be happy to hear them.

[Security Discussion] setmov:
You can do it in a few ways.....

1.st.... if you have custom recovery, reflash a new rom! Done, your phone is clean!

2.nd.... if you don't have a custom recovery, you can use SP Flash Tool, and flash a custom recovey, then flash the rom, or, if you find a suitable rom online, you can directly flash it with SP Flash Tool.

3.rd.... if you don't wanna bother yourself with flashing.....then, here is a quick fix....

Install Titanium Backup Pro version

Enter Titanium Backup and find Time Service and Monkey Test

Freeze them

The buggers won't cause other issues

Hope this helped :)

Good Luck

Normal way of doing things on xda is sharing a fix if you have it, especially that you have such a wonderful track record here.

Why don't you guys ask for a raise from Tim Cook, so that you can polish a little (actually a lot) your trolling skills, so that perhaps one or two people can take you seriously for a change? And remember: never say 'i got a virus on our Android device' because it gives you up right there. Oh, and try to open a sleeper account instead of one which is 1 day old, this way you'll have more credibility. Cheers. :)
[Security Discussion] Nuh99:
Dear sir.

I don't even know what raise are you talking about ? I'm not trolling. I had this virus in my tablet and I also asked on some other forums but what I got is that I have to flash my device which I could not so I went into deep and with collection of information from here and different places I managed to remove it without flashing.

And as for sharing a fix I will definitely share it. Actually I'm not good in steps writing but I will definitely will try to write as how I did.

I am with Optimupro on this. It seems very questionable when someone or a few with all new accounts have an issue and then rather than posting the fix say email or pm me like they want to keep it a secert or its to special to post? Gives the grandious impression. Froma practical sense, why you a.person rather type it out or c&p it over and over for.each corispondance they recieve and require the person to wait for it to be on their schedule rather.than just post it in the forum its associated with??
