I would also like to be able to turn on the screen without power button. It would be good if there was an app that could turn on the screen based on orientation, ie. face down screen off, face up screen on. However, from what I've read, the gyroscope turns off when the screen is off.

In my current setup (carputer) I'm using the fact that the screen turns on when the device is plugged into the charger to wake the tablet up.

you must be looking for this one

the app is called "Screen Off and Lock"

Is there a problem with your power button? Why do you want something like this?

If you have problem with your power button, maybe you can remap your buttons, so any colume button can be power on/off your device (I don't know how to do, just an idea. I'm a newbie :))
[About XDA developers] swbf2lord:
Ever since I joined XDA way back in '09, I've been stuck with the wrong time zone. I think it was because I was using my old Samsung Omnia, and it was so slow with web browsing, I was just trying to make an account without it freezing up, and didn't read everything carefully Anyways, I always assumed that XDA was based in Europe or something and that's why all the times were messed up. About 5 minutes ago I saw the "Edit Options" link in the User CP and realized that's how you change it. Even after 2 1/2 years, XDA still surprises me :D

Just curious as to how much ram is free for most people while idle. Use Android System Info, Widgetsoid, or something similar to observe ram after the device has been idle throughout the day. I'm not interested in people's attempts to maximize this number; I just want to know what it is, on average, without the use of task killers or the like.

Mine hovers somewhere between 300 and 370mb.

i merely studied the file, i'm no expert.

i just know intermediate stuff.

i didn't know what hpf was, so i googled it and found it is high pass filter so i disabled it.

that alone didn't do the job well, the rest was educated guess and i'm glad it was right.

difference may not be that noticeable on phone speaker but can be clearly noticed when using headset.

the experts can now tweak and sort out more stuff after.

here's a comparison of vids:

old is from default

http://www.mediafire.com/?1a0wcd0rdodadd3

new is from tweaked

http://www.mediafire.com/?aob456t4qoyz25c

attached zip is cwm flashable.

UPDATE:

vid recording of sgs3 placed on laptop playing music.

default BFLB:

tweaked BFLB:

http://www.mediafire.com/?63wzv2jd51bzy6o

NEW!!! Default BLG6/8:

http://www.mediafire.com/?se4ioy7x4206n1l

as you can see, tweaked BLFB and default BLG6/8 are pretty close. :)

the default BFLB's audio in vid was very bad, comparing it to default BLG6/8 there is a marked improvement.

samsung has indeed improved audio recording in vids now.

default vid starts around 2seconds, the tweaked at 6th second.

as can be seen on default, this phone is weak at picking up those between 32hz and 64hz.

if you can play the two vids and sync them, you'll see the tweaked picking up more bass than default.

app used in sgs3 is rta audio analyzer found in google play.
[Galaxy S III Android Development] eitama:
There is a notable difference between both videos, but as the sound source is just noise it's hard to say if this is a good or bad improvement with naked ear.

I will be making some test later with your mod, I hope for the best!

Cheers!
[Galaxy S III Android Development] radeonxt:
i have before and after vids of cars passing by just like gsmarena's. as this was where we all first noticed sgs3's bad audio in vid recording.

but sad to say my upload speed here is very slow and the files are over 100mb cos i recorded each over a minute to be sure.

all i can say is the vid with tweaked is better.

i've listened to both using headset to differentiate well, the tweaked one has more depth which many has complained the audio in sgs3 was lacking.

and there is less walkie-talkie effect scratchy noise than before.
[Galaxy S III Android Development] eitama:
You can use VLC to extract the audio channel from the vid files and upload only the audio files.

Then you can record 5 minutes on each, and be left with 5mb for each :)
[Galaxy S III Android Development] radeonxt:
i used mp4muxer, i extracted the aac audio in raw.

default

http://www.mediafire.com/?bbcjfj8j6zkmynr

tweaked

http://www.mediafire.com/?cns7j748i3y2uhj

the best way i can describe it is that the mic captures better now. it was windy when i recorded both a while ago, and only the tweaked version as you can hear captured the wind.
[Galaxy S III Android Development] JF-GINO:
Amazing! This was one of my biggest complaints about video recording with this phone. The dynamic range was cut with a high pass filter and you solved it. Good job and thanks for this!
[Galaxy S III Android Development] vandal4e:
there is definitely an improvement , but still cant record any bass
[Galaxy S III Android Development] dagrim1:
Haven't had the chance to experiment but I understand you completely disabled the High Pass Filter by using HPF Switch and set it to 0?

{ "AIF1ADC1 HPF Switch", 0 },

But another interesting line is the one above it:

{ "AIF1ADC1 HPF Mode", 2 },

Appearantly there are 3 or 4 modes for the HPF:

0 = Hi-Fi

1 = Voice 1

2 = Voice 2

(3 = Voice 3)?

Perhaps setting it to Hi-Fi (value of 0) instead of 1 or 2 (voice) is worth a try as well. I can imagine when the focus is set to voice a lot of surrounding sound is filtered out and Hi-Fi might be more 'general' or 'pure' but without issues of too much noise for the mic?

Will try it out some later myself btw ;)
[Galaxy S III Android Development] JF-GINO:
I tried setting it to 0 last night. Recording quality was about the same. Something I never noticed before. .. even in the audio recorder, or using an app life tape machine records with no low end bass at all.. .. hell even when recording the bloody radio. ... its a global problem with this phone on all recording levels. .. my sgs 2 does not suffer from this.. . Might be kernel related as all the options I try in this file still do not give me any thing lower then

0.5khz. .. pretty stupid limitation.. ..
[Galaxy S III Android Development] radeonxt:
it wasn't just hpf that i tried to tweak guys.

i did say in first post

i didn't know what hpf was, so i googled it and found it is high pass filter so i disabled it.

that alone didn't do the job well, the rest was educated guess and i'm glad it was right.

difference may not be that noticeable on phone speaker but can be clearly noticed when using headset.

just glad that many have confirmed the clarity,volume and such is better.

i'm hoping the experts will include tweaking this more along with their other audio recording fixes, since i can do no more further as i've mentioned i'm no expert and also too busy with business these days.
[Galaxy S III Android Development] dagrim1:
Ugh, yeah... thought I was able to read better ;)

Do you know if you have to reboot when changing this conf file? Or is it done on the fly. Might want to play around with it some more.
[Galaxy S III Android Development] FadeFx:
Could someone possibly do a recording of pink noise out of studio monitor speakers, so he could then do an analysis of the recorded frequency range?

–—–—–—–—–—–—–—–—

tapatalked from Galaxy SIII
[Galaxy S III Android Development] radeonxt:
welcome meltus.

yes i didn't even know what the hpf acronym was.

i googled just hpf and got many results, so i added what is hpf in audio and the search result yielded this wiki:

A high-pass filter (HPF) is an electronic filter that passes high-frequency signals but attenuates (reduces the amplitude of) signals with frequencies lower than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. A high-pass filter is usually modeled as a linear time-invariant system. It is sometimes called a low-cut filter or bass-cut filter.[1] High-pass filters have many uses, such as blocking DC from circuitry sensitive to non-zero average voltages or RF devices. They can also be used in conjunction with a low-pass filter to make a bandpass filter.

was about to search what the hell attenuate means but luckily inside the parenthesis it showed it means reduces.

so knowing the basic stuff that 0 would mean disable and 1 would mean enable, i changed it to 0.

then after that i tried recording with hpf value changed to 0, i didn't notice much difference.

the only time it made a difference like shown in those before,after vids was when i added AIF1ADC1L and AIF1ADC1R on camcorder's built in mic and back mic. i decided to retain the change i made to hpf to 0 since getting a few bass perhaps is better than nothing.

since i was just interested with camcorder, i just looked at what was in there. then i saw settings for built in mic and back mic, one was just L the other was R. so i figured one was used for Left and other was used for Right. the aif1adc was simply just aif1adc, i found an aif1adcL and aif1adcR so i tried putting both on built in and back mic because i was thinking builtin mic is the one on the bottom and back mic is the one on top.

thank you meltus, i noticed another thing maybe we can try to tweak in those mic settings and it's

{ "IN1L Volume", 30 },

{ "MIXINL IN1L Volume", 0 },

and

{ "IN1R Volume", 30 },

{ "MIXINR IN1R Volume", 0 },

how about we try playing around those and upping those volumes?
[Galaxy S III Android Development] radeonxt:
i use cwm manager and select flash update then select that zip file.

so it loads since it restarts after it finishes flashing.

its fast since it's only a 197kb zip file.
[Galaxy S III Android Development] radeonxt:
yes, there are many experts and audiophiles here in xda that have the knowledge and the gadgets to do this stuff.

i for myself can only use rta audio analyzer which can be found in google play.

the number of bands i chose in options is 20 - 1/2 octave.

then i played on my laptop black eyed peas let's get it started and place the sgs3 on the laptop's keyboard.

the thing i noticed is that 250hz to 16k range all get picked up and can reach about -40db.

the weakest pick up is between 32hz and 64hz.

my guesswork says the ones on the left side are for bass right?

center to right are mid range to high pitches?
[Galaxy S III Android Development] Meltus:
Ah, so it was the "AIF1ADC1L/R" lines that actually made the difference? That's interesting, I wonder what other lines we could add to gain more control?

I think that the Volume parameters will simply be microphone gain, so to achieve clearer results we could try lowering that value so the microphone distorts less. Or, the "AIF1ADC1" value could be something to do with the HPF and could perhaps control the cut-off value?

There's a lot we don't know, it's a shame Samsung didn't provide us with any documentation about it! :D

I also have a pair of ADAM A7X studio monitors so I'll do the "Pink Noise" testing, as suggested by FadeFx, with those later and see if changing the HPF mode value actually does make any difference.
[Galaxy S III Android Development] radeonxt:
yes AIF1ADC1L/R that made the difference.

can be clearly heard when we use headset.
[Galaxy S III Android Development] JF-GINO:
As for low end recording,

Changing AIF1ADC1 to AIF2ADC2 gave me low end roll-off around 200Hz lowest point at -30db was 163Hz.

What I did:

I recorded a few bass kicks, drops and rumbles from a few VST plugins, put the phone next to my Monitors (and the Sub) - recorded audio/video and then I used the linear frequency graph in Cubase to see what my recorded waveform was doing.

This is the Mod I tested :

Modifier "Camcorder" {

SupportedDevice {

"Builtin Mic"

}

Enable {

{ "AIF2ADC2 HPF Mode", 0 },

{ "AIF2ADC2 HPF Switch", 0 },

{ "IN1L Volume", 30 },

{ "MIXINL IN1L Volume", 0 },

{ "AIF2ADC2 Volume", 96 },

{ "AIF2ADC2L Mixer ADC/DMIC Switch", 1 },

{ "AIF2ADC2R Mixer ADC/DMIC Switch", 1 },

AND REPEAT FOR THE "BACK MIC"

I modded the values in Voice for recorder to match what I had done in Camcorder Modifier.

Try it, record bass from a sub and see - I got results (High-end was untouched)

EDIT::::::.........

This did not do what I thought it was doing. Turns out thaqt Sub frequencys where recorded below 300Hz, but up from 90 to 30Hz - there is a 'Scoop-out' so this didn't really do anything significant.

BTW - in AIF2ADC2 the ADC stands for 'A'nalogue to 'D'igital 'C'onverter ... no filter preferences there - but maybe switching it to a different ADC will give 'Full Range' processing???
[Galaxy S III Android Development] radeonxt:
yes i did try 0'ing or disabling those hpf in the enable parts last night and compared results.

wasn't sure since there is no noticeable difference and knowing laptops don't give out good bass as compared to speakers with subs.

and yes that's another one who has noticed that, from 32hz it gets better than nothing bass then onwards to 64hz the eq bar of rta audio analyzer for android shows it mostly stays at the bottom most of the time.
[Galaxy S III Android Development] jody2k:
Any chanse to tweak or lowering the mic gain? Im on festival now i could record some examples
[Galaxy S III Android Development] Meltus:
Yeah you should be able to.

There are volume options under the in-call and camcorder sections so I can only assume one of them at least refers to the microphone gain. Just reduce that value and you should be good to go! (Not been tested though)

I never got round to recording and comparing some audio samples by the way and I'm away this weekend so I'll try and do it when I get back! :)
[Galaxy S III Android Development] dagrim1:
Also wondering what the best way to test this is, recording wise... Guess I'll just play some nice music, play it loud and record it. (Sounds like fun, maybe not so much for the neighbours though). :)
[Galaxy S III Android Development] TSport-:
Work quite well

Thanks a lot for this fix.

I tested it today with some heavy bass music and now the bass is indeed recorded. Although I almost had to put the phone inside

the woofer to record a real punch :) There also seem to be no more clipping than before but somehow it sounds overcompressed

(low bitrate-ish) at higher volumes. I didn't notice this without the mod but I guess that can be addressed in the camera app.

Extract the rar file via winrar or any other zip manager

And u will have the desired file :)

you flash the zip file using cwm.
[Galaxy S III Android Development] saddameu:
nevermind, seems that it worked just by copying whats in system folder into original system folder from my phone, the meta folder seems somehow useless.You don`t need any cwm but at least now i know what is it now.You can clearly see the difference, the default recorder was so annoying.Waiting for supercurio to see if he can improve the audio recording even more.Thank you for this great fix.Here are 2 videos before and after the fix , they should go to the first post so that everyone could see the results.Note that if you are playing the videos on a laptop or some tiny speakers you won`t see any difference.

[Galaxy S III Android Development] radeonxt:
oh okay.

yeah you can do it that way for this since it's only one file.

i only recommended through cwm since it's automatic.

thanks for your confirmation that this indeed works in getting better audio than stock and is picking up/recording more bass than it used to.
[Galaxy S III Android Development] saddameu:
but take a look at the same recording with the galaxy s2, the bass is much better

https://dl.dropbox.com/u/70816091/20120721_183115.mp4

I just hope that they didin`t screwed the hardware and is just a software issue, this need to be improved more.

DEFAULT BLG6/8:

http://www.mediafire.com/?se4ioy7x4206n1l

-Worst: default lfb (for sure)

Now between tweaked and default lg6/8:

lg6/8 was less "high pitched" than the tweaked lfb.

I don't know the ACTUAL noise of the fan, so I can't tell which is best or worst.

However, there is definitely an improvement over the last non-modded stock - that's for sure.
[Galaxy S III Android Development] saddameu:
is nice to see that samsung did something for this, is an IMPROVEMENT not a fix.The bass is still tiny compared to my s2, a song have the correct base if I put my s3 at 2-3 cm near to my sub-woofer but on my s2 the song has the correct base at 2-3 meters.
[Galaxy S III Android Development] ididnt:
can someone tell me what happened to the audio on the following link. It happens on all my videos from S3

http://youtu.be/sFRihC2DVP0
[Galaxy S III Android Development] jody2k:
Yes tbe s2 was recording more bass but it could only record at low volume levels, the s3 hass less bass but can record at very high DB levels (above 120db) without too much distortion. The choice has to be made, as for the size of the mic you cant really have both you need a bass cut off/noise supression.
[Galaxy S III Android Development] saddameu:
yeah but in real life you go to a concert few times per year so I don`t care to much about this, the best way would be if we could have 2 options for more bass-normal sounds and less bass-loud sounds.
[Galaxy S III Android Development] pennzoilgtr:
i just done up a comparison between both LG1 and LG8 on both different phone. though i don't have LFB. but generally both LFB and LG1 are the same.

and LG6/8 is apparently less "high pitched" as mentioned by TotallydubbedHD

LG1 - http://youtu.be/Fw1u7diImNw

LG8 - http://youtu.be/GioSXbxbhcA
[Galaxy S III Android Development] jody2k:
Yes noticable difference, lg8 has more headroom and bass
[Galaxy S III Android Development] jody2k:
That would be great indeed i just hope that the mic isnt hardware limited
[Galaxy S III Android Development] pennzoilgtr:
yup.. preferred the mic from lg8 alot more now :D

i just felt that LG1/LFB felt too "noisy" when you speak infront of the your phone.. and LG6/8 sounds more filled and natural.

---------- Post added at 07:24 PM ---------- Previous post was at 07:18 PM ----------

in my ex motorola atrix, the video recording function has a feature for different mic recording mode. "Normal", "Concert" and "Outdoor". so Concert setting records at a much lower setting, so tiny that it has almost no distortion in a concert environment.. so i was wondering why a samsung flagship phone wouldn't include such feature in?
[Galaxy S III Android Development] radeonxt:
i finally had the time to compare LFB/LG1's stock rom's default settings and LG8 default settings.

haven't finished comparing both files as i'm halfway through, i have to pause and rest my eyes a bit to post this initial finding:

1. my trial and error is on the right track. samsung has indeed zeroed HPF mode in LG8's default settings.

2. my tweak to disable hpf was only for mic. samsung included also for headset in, my educated guess for that is when you are recording videos with headset inserted.

3. new line added in in call capture capture modifier which i think means the hidden voice recorder during calls:

{ "AIF2ADCL DRC Switch", 0 } disabled for mic and enabled for speaker.

and that's it.
[Galaxy S III Android Development] discophil:
