[Q] [Question] Why is Galaxy S lagging?

Hi, I've seen a couple of lag fixes out there and they seem to be working well. But why is it lagging? Slow rom/internal memory card? Bad FAT32 filesystem as one of the fix developers said in a thread?
I am curious about this because if it's hardware problem then I might wait for a bit longer before upgrading my phone and Samsung may be already working on it, but if it's just software then I like to get a new phone now (from my good old E71)
thanks a lot!

While the 16gb hardware is slower then the 1gb rom used it is not why it is lagging..what is causing the lag is Samsung decided to use their proprietary RFS file system which either does not work well with Android in general or has too big of a footprint aka inefficient thus causing a bottleneck of the I/O

cheers, then what about the leaked 2.2 ROM? Has Samsung done any improvement in the I/O performance at all?
I really like this phone but the laggy issue is annoying.

Well looks like not all galaxy s are lagging. You can find many people on forum without this problem. I'm one of them. 55 apps, adw, no task killers and no lags at all.

i'll disagree with the lag
i'm still using the stock ROM on mine, and i don't experience the lags some people are having.
i can browse fast, switch apps fast, play audio/video fast, launch GPS app fast, and get a lock fast even when the car is moving on the road already
i do leave stuff like Fring running in the backgroup for my IM and video calls, meanwhile the music player plays via Bluetooth to the car Deck or BT headphones, and using GPS to check my route for speed, traffic jam, etc.
email is constantly syncing, set to auto sync every hour
if i want to check the weather it loads up instantly

thanks a lot, you guys. But which Galaxy s are you using? Maybe there is a superior version or....I am in the UK so probably the international version?

i have the uk version, bought2 weeks ago. I noticed little lag, nothing major at all.
I decided to do the lag fix and the phone is now realllllyyyy fast with no lag

UK version from o2

yes UK unlocked version is the international version, the same one from HK, and Singapore and many other countries from the old continent.
Except Korea / Brazil / China / USA they have their own.

I'm finally getting 0 lag too now I flashed to JM6 (I got lag on every other firmware). My Compass works for the first time too. I haven't tried GPS testing yet but my hopes are up. You may want to give JM6 a try.

afaik recent firmwares (jh2 for ex) have a fixed RFS driver that doesnt lag up and fragments, whatever the real technical reason is why Rfs is slow on first generation firmwares, so the "not all get it" isn't really just "luck" stuff.
actually this regular "my phone dont do this ur just unlucky" is just some form of disinformation that is pretty much annoying.
you can check if you get 1500+ in quadrant, you don't have the issue (and IO tests go through quickly), otherwise, you do

The stock galaxy s only gets about 800 in quadrant, but that score is only bettered by the nexus running froyo. It scored better than nexus on 2.1, desire and a gamut of other phones. But I do not read about these phone owners gripping about lag or need to go above 1500 in quadrant. Why?
Frankly, I have done the lag fix and my quadrant score is now 2137. But I do not feel any significant difference than when it was only 800. In other words, I dun feel that the phone was slow before the fix.

thanks everyone, I've got to say this is the most helpful forum I've ever been to.
gonna call Three for a upgrade offer

Umm.. Don't take Quadrant for gospel. You could dump most of the OS on RAMdisk and you'll get awesome scores. We need a few test cases to ACCURATELY demonstrate the problem reliably, because quadrant only tests a few cases...

After installing the lag fix I noticed things were hanging more than normal. Un-installed it and things are fine again. Not sure if it was just something I had installed or what, but my phone still feels as 'fast' as after the fix.

yay!!!!!!!! i found my very first lag today
i had running media player over BT, GPS copilot, GPS mytracks, video Fring, and got the super mario running in the live wall paper
everything was able to funtion properly with some delay of course, with the exception of mytracks and media player
i'll try to reproduce the problem and see if i can pinpoint which of the 2 program is causing the lag (mytrack vs samsung media player)

Quadrant scores really have **** to do with everyday performance for the majority of people. You can post up 2300 in Quadrant and still experience lag during normal use. Think of it like 3DMark vs. Actual game performance on a PC.
Every phone is susceptible to the lag problem as every galaxy s uses Samsung's proprietary rfs format. Also, Crapwiz is part of the problem. The sooner Samsung and other manufacturers get their heads out of their asses and offer their products with stock android, the better. Give people the option of using Sense or Crapwiz but dont force it on them.
It speaks volumes to the quality of Samsung programmers when Launcher Pro is smoother while running on top of Crapwiz than Crapwiz by itself. The sooner the ASOP ROM is finished, the sooner the phone becomes more pleasant to use by those of us who dont need shiny things, facebook/twatter and iphone ui clones waved constantly in front of us.

Personally, i noticed slight lag.. very very slight lag or hanging when opening some apps for the first time.
However after upgrading to JM1, i haven't noticed that at all. Not saying it is solved. This has just been my experience.

We don't know thats the cause.. Someone said the reason RFS was slow is that "it doesn't buffer stuff" before.. But never seen confirmation. So anyone have actual proof its RFS?

I was on the stock firmware DJF4 and this has lots of lag. I have about 200+ apps installed and it usually takes a long time to boot up (esp Appdrawer). And after using awhile with it, even opening phone/messaging/contact lags 2-5 secs.
I upgraded to the official DJG4 yesterday and now the phone performs much better and battery life has improved (i.e. the standby time increased 30-50%) with the same apps/configuration of the old firmware.
After 36 hours with the new firmware, I daresay the lag issue is now gone. The DJG4 firmware also comes with handy task manager. Free RAM now seldom goes below 60MB. I tested by opening 20-30 apps over and over and there is still no lag. And I dont even have a auto-kill task manager running.

Speaker volume too low

I'm praying for someone who can solve my problem.
I LOVE my n1 but I dont hear it when Im outside home.
I surfed tens of forums searching for the solution and there is no dsp manager or lvh that has been able to solve the problem.
can someone help please?
p.s. i heard that maybe cyanogenmodded rom on gingerbr could solve the problem but i heard also that it uses dsp manager which wasnt working on my n1

Are you using a custom rom?
Most custom roms have an audio boost over stock. And maybe that DSP Manager would only work if the ROM supported it, so that could be why nothing has worked sof ar if you are on stock.

I think you're looking for the vibrate option

the audio boost is present in most custom ROMs such as cyanogen. so you really should have no problem if you use that. i know my volume has increased very well using cyanogen so i dont have any complaints anymore.
i do remember in cyan 5.0.8 that the audio hack was TOO loud and people complained, so the dev's reduced it to somewhere in the middle. perhaps you can go try that old ROM and see if that helps just as a test. if so maybe you could edit your kernel to match that old hack? might be a lot of work though...

i'm using one of the gingerbr roms from this forum
so you'r suggesting me to wait for the cyano's gingerbr?
p.s. today i bought an ideos for my old father ((( its LOUDER AND LOUDER than my n1 (((((

Unfortunately, you will have to live with crappy HTC speakers I am afraid. Rom's don't have a significant difference - I mean it will still sound crap :/, I don't know why HTC keep doing this.

dont say me so! please! i heard about people who solved and had to REDUCE volumes beacause the loudnes made the speaker clip instead!
i wanna clip my speakeeerrrrr!

Try enomthers Official ROM with the AudioMod kernel. I now run my incall volume at 50% where on the stock ROM I had it maxed all the time. The speaker phone is actually useful now as well. Besides this excellent perk its also a very fast and stable ROM with lots of features that I've found I can't do without. I ran a Gingerbread ROM for a week and was so happy when I switched back.

do you know if it's possible to flash only the audio hack? i'm just running stock cyanogen 6.1.1 and i would like to play around with the audio hack. can i flash it somehow, or does it have to be built into the ROM? and also, i have a build environment set up, so could i just play around with the kernel code for the hack, and compile my own kernel for testing it out?

Can anyone suggest any 'good' solution? kernel or otherwise to fix this $#@$# 'bug' of low in-call volume in Nexus One??
Would really appreciate all the help!

24bit 96khz audio playback

Just curious, can the Dinc play 24bit 96khz audio (or 192khz even)?
My failpod cannot, and when i upgrade i was going to turn my phone into a iTouch basically. So i want to make sure it can play my files.

I have never thought about it. Good question.
I really doubt the stock player does anything of the sort, as the mass population appears to want higher compression and lower quality.
I just looked at Neutron Music Player in the market (evaluation trial). It seems to do 96k, but does not mention 192k (in FAQ on website). I poked around the forum a bit... it sounds like high frequency sampling will burn through the battery really fast... and that makes sense. For high frequency sampling, it says you need a 1 ghz processor. Therefore the Dinc should be able to do it.
But, I've never used the app and I don't know what I'm talking about... this is just what I read in the last couple of mintues.

Not to concerned about battery life as i have the extended battery, and once i have my new phone (which is when this will be my dedicated itouch) i plan on building either a GB rom from Cyanogen, Or a ICS rom from AOKP without phone capabilities. should help battery life when it's not always searching for towers

High Audio Latency In Galaxy S6!

MODs feel free to move this thread if this isn't the right place for it, and I'm sorry if it isn't
Q: What is audio Latency?
A: Audio latency is defined as the time delay that a signal experiences as it passes through a system. On a mobile device, this is deeply related to how long it takes between tapping on a screen and receiving audio feedback.
Q: Why should I care?
A: Low audio latency can be the difference between an immersive gaming experience and an unpleasant, disconnected one. Too long a latency and a device can begin to feel strangely laggy, even if every visual animation is snappy and responsive. It is especially important — essential, even — for recording and composing music, since slow audio feedback can easily throw off even the best artists and destroy their creative process. Low latency is absolutely fundamental in a modern operating system, and it's been absolutely terrible on Android.
Unfortunately, iOS has always been way ahead of Android in terms of audio latency. Even iOS devices as old as the iPhone 4S (and much older) have average latency levels of about 7 ms.
Nexus 4 running Android 4.2.2 had an estimated audio latency of about 195 ms, and the upgrade to version 5.1 brought that down to just 58 ms.
Speaking of Marshmallow, The Nexus 9 saw the largest gains, dropping from 32 ms in Android 5.1.1 down to just 15 ms in 6.0
and the Nexus 5X and the Nexus 6P both have very acceptable levels of 18 ms.
Now , The thing whcih worries me most is my Galaxy S6 (920-I) has an audio latency in range of 140ms-160ms running Lollipop 5.1.1 (on several trials)
My device status:
SM-G920I
Rooted,
ROM- Xtrestolite 2.4 (deodexed)
Hacks- Wanam Xposed, ViperMod, Dolby Audio.
So I dont know if all these modifications are what afftecting my S6's audio latency. So I request all those who are interested to measure their device's latency and reply back here . Especially those on stock rom unrooted and all.
Please also include your device status too. even screenshots if possible. and also share if you've had issues regarding to this latency(in games may be?).
Q: How to measure ?
A:There are several ways of measuring latency, and a very useful and easily understood one is called round-trip latency. Round-trip latency is calculated by inputting an audio signal into a device and measuring the amount of time it takes for the signal to exit the output

I'm getting 40ms on my S6 G920I unrooted, stock ROM. I ran the test twice and got the same results. Difference may be attributed to buffer size and the audio mods you may have installed on your phone. I will try with my HTC M8 which is rooted with V4A and Dolby Atmos installed.

your rom have sapa? with that i've 38ms of latency in stock rom

My HTC did much worse. Disabling V4A and Dolby Atmos did help a bit though. First pic was with all effects on. Second pic was with all effects off.

40ms here too with viper and adreilux hardware EQ

I'm getting ~150ms on a g920i with Xtrestolite 2.4 without any audio mods. I think it's the rom since others are getting ~40ms.
Probably more to do with the fact Xtrestolite is using an older samsung base.

I doubt older base is the issue. It's not like samsung figured out how to reduce the Latency by more than half in just months When it took google so much time [emoji6]

Your right this is not good...High latency is mostly a issue of the internal DAC i'm sorry to say if thats the case this is not solvable.
I hope for you guys its just a software problem is some way but the availble audio mods dont have any effect on the latency.
For the op: Try a full clean whipe and total factory reset

1080p lag

Currently using THOR 1.5 rom with the patch fix and didn't click HD Lag Fix, but there's no 1080p 60fps playback available. Last time i tried the ROM, I did click on it but 1080p60fps still didn't work. I'm having difficulty understanding whether or not ROMs actually support 1080p60fps playback, or if i should just flash stock lolipop rom+a good kernel. On a side note, if anyone has done that which kernel did you like most? Any help relating to anything i've said here would be EXTREMELY helpful. Thanks!

I kinda doubt 1080 with 60fps works on this hardware. Others have asked about this too, but I've never seem a definite answer.
But I'm pretty sure 720 at 60fps should definitely work.

Yeah i'm entirely up to date. You've helped me before, and thank you very much for that, so i'm interested in what ROMs you use. What kind of battery life do you get with it and what battery does your S4 have? Sorry to get off topic, want some info from someone more experienced with this kinda stuff.

My S4 is on complete original state (except for the software), so that means it has the original battery. The battery is 2 years old so I'm pretty sure it has lost some of the storage capacity.
Anyway, I usually don't let the battery go below 50% (heard it's bad for it). The SOT from 100 to 50 is usually around 2 hours. Do note that I'm referring here to constant use, not accumulated use.
When I download stuff my SOT is 1 hour, from 100 to 50.
So if we extrapolate the numbers we would get 4 hours for 100 to 0, which is pretty average for the S4.
I've been a long time user of JDCTeam ROMs. But currently I'm looking to see what Slim6 offers.
I don't have any kind of battery tweaks applied.
