Does disabling fsync cause any problem??
What's the benefits?
+) Faster data transfer speed.
-) You can lose some files in case of a random reboot or something like thay (Not entirely sure when you can lose data)

Will i loose my data if i restart the phone manually?!
On what situations i will loose my data?
I'm so confused about that disabling fsync is good or not!

Random reboot.
Leave it enabled.

You can have one at any moment. Leave it enabled, you won't see a big difference.

So i've noticed it a few times now - whenever I finish up a long call (say longer than an hour or so), my Dream becomes extremely sluggish. I've tried killing everything reasonable with Advanced Task Manager but nothing seems to help. I'm usually forced to reboot.
Does anyone know what the problem could be, or a way i could fix it? Is there a better task manager i could be using?

I'm reasonable sure that taskmanager doesn't kill the phone service (I think it runs in the background, check under processes) try killing it manually from there and see if that helps at all.

Be warned though it might cause the phone to hang if its a needed process. So don't go "damn you hnocturna!"

Try increasing the CPU frequency.
Cpu is already locked at 528 with setCPU...
Is it possible that this is a hardware issue?
I don't think so, if its still a problem, try reflashing the ROM but with a wipe and clean a2sd. Start fresh!
Hello,
Is there a possibility to disable the delay that I have from the moment I press the unlock button to the moment the screen turns on?
At the moment I have 2.5 seconds delay from the moment I push the button until the screen turns on.
Am I the only encoutering this delay? didn't see a similar post anywhere on the web

My phone has the same behaviour and the "problem" (if you want to call it a problem) is also described in some german forums - so no, it seems that this is absolutely ordinary.
I had the chance to compare it with a I9000 and the I9000 will outperformance the I9001 at this point, but nonetheless for me it is not really disturbing or so.
any updates on this one? Can someone please help? It's driving me crazy
Hy
I've read about the same problem on a hungarian forum, but I don't have it, mine turns on in less then a secound.
I think if this is such a common problem, Samsung will fix it. Maybe write them a mail.
When the screen has been turned off for a long time, the first unlock takes a lot longer than the following unlocks. For me, I think the 'cold' unlock is 2.5 seconds while a 'warm' unlock is just 1 second.
But yeah, this clearly is a standard problem. Let's hope Samsung brings out a firmware update soon to fix issues like these.
Mine has same "problem". It seems that the phone is in somekind of sleep.
i believe that problem is fixed in 2.3.4. Try flashing that and i hope you won't have that problem...i mean this is how it works:
1. I9000 uses SGX540 which uses less ram for its vram so you have around 250mb+ free ram
2. I9001 uses Adreno 205 which uses a lot of ram for its vram so that you have about 120mb left only
3. Try using no frills CPU app using root and set the minimum frequency to 245 mhz or maybe higher...and you won't get any delays..
Unfortunately it is not fixed with 2.3.4 as I still have the issue.
I will try your suggestion with the CPU frequency

The standard value for the minimum frequency is 245mhz! But it would be stupid to set it higher, because this will of course drain more battery.
I set my minimum frequency to 122mhz (scaling: on demand) and I noticed no differences regarding the delays (like I said before, I do not have a problem with a delay of 2,5sec) - but I have a better battery lifetime without charging.
I will give both ways a try, but to be honest the 2 + sec delay is anoing for me.
Edit:
Even with 1.4Ghz as frequency there is a delay, not that long but still about 1,5 sec.

yup it will...then you should wait for a better custom rom with all those JIT and ram compress tweaks enabled and then you can enjoy the speed.
To be honest if you guys want your problems to be fixed, do support the devs as much as possible in this thread

Yeah but in my opinion setting up the minimum frequency is not an option, because it is a more battery draining setting.

mate, you can never have performance with battery conversations...it's inversely proportional.
1. Set maximum value to 1 ghz with minimum of above 245
2. Do a hard reset from going into settings -> privacy -> factory reset because i just did it recently and my phone's running much faster.
Just had a chat with a guy from samsung support and he said that there is nothing they can do.
There must be a tweak or something to decrease this delay

I did, one day it shut down on me twice. It turned out like you turn it off, but then I couldn't turn it back on, just after battery reset. Never happaned again since then.
You mean factory data reset by hard reset?

Interesting....what version of android do you have (also kernel)
Mine reacts slower if I leave it longer. (samsung explanation "It is because the phone is entering in some kind of sleep state"). When I said that Galaxy s2 reacts instantly the answer was that Galaxy S2 has a better microprocesor and has a different platform.. hmmm

well, i've done that a couple of time already without knowing it being a fix for random shutdowns...but really it's a bit annoying, it just turns off by itself..
You can see it here, the difference is huge:
https://plus.google.com/+JeremyCamp1337/posts/iDyPjEuEf51
The question is, will it be possible to turn it off or anything? (I doubt F2FS will help a lot with that.)
only the nexus 6/9 that ship with lollipop have it turned on by default and can't be disabled. the older nexuses have encryption off by default, you have to go into settings and enable it to turn it on. after i got the lollipop ota on my nexus 10, the encryption was disabled. I gave encryption a try just to see how it performed. what it does is reboot after you turn it on and runs an encryption program. took about 15 minutes or so with a 32gb drive. then it reboots back into android. performance was noticeably slower. only way to reset back to no encryption is to factory reset the device.

We don't need to turn it off. It's already off by default on the N5.
Sure it affects speed.. but I ran a 2012 N7 encrypted for ages (and that's already got speed problems) and it wasn't as bad as that benchmark implies... Few % difference, not so noticable. Is it actually testing real metrics like app startup speed or some kind of artificial read pattern?

Uff, it's good. I thought it gets enabled by itself without information...
Yes as mentioned, it will affect speed. When you enter the encryption password at boot, it doesn't decrypt all the files (that would take literally hours), It just allows you access to the files in their encrypted state. This means the files are decrypted "on the fly", or as you use them / move them / open them.
Encryption always has and always will have an overhead
Hm, I've got it enabled, feels good so far.
at leats its not forced on n5 no wonder why arstechnica have a sluggy and slow performance on n6 android L con n6 seems to be LAG and not lollipop hopefully google fix it by not forcing encryption or improving the algorithm

This. I don't know why this surprised anyone.
"Oh? Performing a mathematical operation against every bit of data before it is read or written affects performance? Really?!"
I'm just glad Lollipop didn't force it on with the N5.
Where exactly can you turn encryption on or off after installation of Android L? I can't seem to find it in settings...
U Can only turn it on, if u want to switch it off, a userdata wipe is the only way.

under settings go to security, then to encrypt phone. The only way to turn it off is to do a factory reset

I used to have full disk encryption on my OS HDD, and I am running it on my OS SSD. Performance impact was noticeable in the former case and not so much on the latter. But for N5, it made me wanted to smash the phone with a sledge hammer. Slowdown was just so painful for my setup/apps/personal use. My guess is that N5's CPU has no hardware support for encryption, and while a 300 MHz (maybe???) overhead for an Intel Core i7 is nothing, it's a huge chunk for current phones' CPU.
In short, as it currently is, I am happily running full disk encryption on all of my devices except the Kindle and N5.
There's nothing new under the sun...
BTW bbedward has modified boot.img to disable the forced encryption on N6: http://forum.xda-developers.com/nexus-6/development/disable-forced-encryption-gain-root-t2946715
So from what I've seen disabling the encryption speeds up the N6. Is it anything I would see in day to day usage or just something I can measure with system speed tests?
Is there any reason I would NOT want to disable it? I'm just a normally daily user who plays on Facebook, reads forums and texts.
Also do I have to wipe the phone again to turn the encryption off? Thanks!

again. this "speed" that you are talking about, is not your actual phone itself. your reading and writing to your storage is slowed down a little, your actual phone is just as fast being encrypted as not being encrypted. it just how fast it reads and writes to your storage, thats all.

Yes I got that part and that is why I'm asking. I guess I should have said will it make things like playing games quicker due to loading speeds? Like standard SATA Vs. SSD etc on a computer.
I decrypted mine and it does save big files faster such as when I do a backup. It really depends on what you want out of your phone. I disabled mine because it kept causing TWRP to have issues when rebooting.
hey so my s21 ultra which was working normal until yesterday started to lag out of nowhere ... the only thing that i did different in these 2days was gaming with my new clip on xbox controller and testing different games ,
I didn't install anything new EXCEPT that octopus key mapper and then Mantis gamepad pro but i didn't really set them up EXCEPT i just tried connecting my s21 ultra to my note 8 via usb c just to test if it worked but then note 8 ran out of battery like crazy...
It just looks like that app did it but i uninstalled all of them but still it is there...
any help? i don't want to reset anything !
Clear system cache.
Try in safe mode.
See which system apps are the most active, delete their data.
A user hidden setting may have been altered by a poorly written app, a possible rootkit etc or a hardware failure.
Factory reset if you can't find it soon.
does it lag in safe mode?
submit an error report on samsung members app > + button > error report if you think it's a software issue

That last line will make things difficult.
That would be the most foolproof software solution for a non rooted phone IMO. If you reconsider, I'd suggest a full hard reset.

Hard reboot or factory reset?
A hard reboot is fine. However a hardware issue may be present if this is needed.
Factory reset; it's always preferable to find and correct the root cause rather than doing a factory reset as the issue is likely to reoccur.
Exceptions; unremovable malware, rootkits, major firmware updates, old loads and altered hidden user settings.

Backup all critical data now.
Find the cause before it boot loops you.
These are typically the only warnings, if any, before a boot loop. This is not normal behavior.
See which apps are using the most battery, try force stopping them, clear their data, disable them temporarily if possible.
Disable any power management!!!
If using a 3rd party launcher or power management, disable it!!!
Try in safe mode.
Take all factory installed apks especially system apks back to their factory load versions.
Turn off all cloud apps including Google backup Transport for now. Turn off Google Firebase.
Turn off all Google, Samsung, and carrier feedback.
Try temporarily disabling Google play Services, clear it's data.
Reset network settings.
Clear system cache.
Try a hard reboot.

so i fixed it after going to safe mode and realizing that it was not the system apps, then i reinstalled that mantis app and uninstall it again to make sure if it was stuck or not also there was this app called : NET SPEED INDICATOR that was updated recently and was flagged as crashed in device monitor so i uninstalled it too and boom, the device was normal again.
so happy that it was a software issue rather than hardware or malware one since i keep close control of what i install and not and monitor everything it was surprising to see such things in my phone, after years of Samsung phone usage it was really shocking to see such behaviors on my s21 ultra with freezing and crashing non stop.
thanks for the help guys!
