[Samsung Galaxy Nexus] schwiz:
I just got the Sprint Galaxy Nexus. I went into the security settings and enabled facelock. I clicked owner info and added my info and checked the 'show owner info on lock screen' box. But alas, the lock screen doesn't display my info. I thought maybe its because of facelock so I tried it with the pattern lock as well and that also didn't work. Anyone have any ideas on how to fix?
[Samsung Galaxy Nexus] TheMarvelous:
Was your battery kinda low when this was happening? I noticed that it only displays it when the charge is like about...20 something.
[Samsung Galaxy Nexus] schwiz:
ahh, it wasn't low on power, but if it is charging it doesn't show.

Thanks!
[Xperia Arc Q&A, Help & Troubleshooting] nagurvidyasagar:
I am trying to install CM9 on my Xperia Pro. When I flash with CM9 ROM, the phone is not booting up.

Then I have tried to install CM7.2 which is working fine. But in CM7.2 I found that phone volume is very less. I can hear the ring sound when it is in my pocket.

I bought ROM Manager Premium and then tried installing different versions (downloaded ROMs from XDA Developers forum and other websites, may be same versions with different file name) of CM9. Whatever the ROM I have tried, the phone is not booting. It is stopping at initial Free Xperia Project Logo. Even if I wait for 30 minutes, it is staying in the same screen. I have to remove the battery and restart the phone and then switch back to CM7.2.

I have attached screenshots of my phone details. Kindly help me installing in CM9 or any other ICS ROM on my phone. The worst part is, I cannot repair the phone using Sony Ericsson PC Companion as it says, phone cannot be updated because the phone contains modified software.

I am a newbie for Android. Please help me installing in CM9 or any other ICS ROM
[Xperia Arc Q&A, Help & Troubleshooting] shybby:
Hello.

I think that your problem is the different boot.img .

First of all you have to flash the new boot.img via fastboot (you can found it in your android-sdk folder. otherwise just download it.

After flashing this new boot.img (you can find this img in the *.zip file of the ROM)

you have to enter clockworkmod-recovery (at boot hold volume down or tap it some time).

Next would be deleting data, dalvic and installing your new ROM.

Hope this will help you.

[HTC One X] jfrock25:
I succesfully rooted my phone.

I went to install Android Revolution. I think I goofed.

I first dowloaded and ran the the Intsall boot.bat

I did not first put the Rom and SuperWipe on my SD card.

When I went to boot my phone backup it boots into the fastboot menu instead of booting up the phone. It does this everytime I restart it.

What do I do? I cant post in developers forum for help as I dont have enough posts.

I restored the backup I created in clockwork but my phone still does the same thing.

How do I know which RUU to download? Im in the US and purchased a International One X.

Alright -

I noticed it said the version of RUU in the fastboot screen at the top. I started the download last night and went to bed. Just woke up. Good news is I took a few days of work so I have one goal this morning.

Must get One X working again.

Wish me luck.
[Acer Iconia Tab A100] hahne:
I am looking for a notetaking app that works well with a stylus. There are several problems with the ones I have tried:

1. The stylus skips on the A100 screen, unless I use a lot of pressure.

2. My palm puts unwanted marks on on the digital paper.

3. I cannot find one that does OCR to make the notes searchable or convert them to text.

Am I dreaming to find such an app and use it with the A100?
[Acer Iconia Tab A100] goofball2k:
1. What stylus are you using? What OS are you using? I've found ICS has fixed the screen issues that I was having with not recording all the touches on the screen.

2. How do you get palm marks on such a small screen like the a100? I don't ever feel the need to put my palm down on the screen when taking notes.

3. I have only tried TabNotes but it doesn't have OCR.
[Android General] tehh4ck3r:
Just wondering, but why are a bunch of phones (like the One X, and possibly the Galaxy S3) with LTE versions for the US using different SoC's? For example the international One X uses the Tegra 3 but the AT&T version uses the Snapdragon S4. Why doesn't the US version just keep the Tegra 3?
[Android General] IAmAN00bie:
Something to do with the Tegra 3 not being compatible with an LTE chip? I think the carriers want a chipset that has integrated LTE. Not entirely sure why.
[Samsung Galaxy Nexus] sean1984:
1)correct

2)correct

3)correct

4)correct......it also backs up radio too

5)usually a good rule with tb is to only restore apps and app data, and not system setting an prefs so things dont bug out going from rom to rom

6)usually best to wait until dev updates their custom rom to new firmware(devs update rather quickly) better than unrooting then rooting stock rom only later to flash a custom rom that has been updated to latest firmware

7)most if not all custom roms are already pre-rooted

YOU PASSED!!! :D:D:D

[Off-topic] MountainDew Man:
I didnt find any other threads for this so I made one. Just looking to see if any DSM owners are on here, meaning if you own a Mitsubishi Eclipse 1989-1999, Eagle Talon 1990-1998, or a Plymouth Laser 1990-1994 post here.

1998 Mitsubishi Eclipse RS, picked it up last year in February for $850, with about 190k on it with a new timing belt, and clutch. Its still pretty much bone stock it only has a short ram intake and 3.5MM MSD ignition spark plug wires.Cosmetic changes are black painted center piece, GS wheels, aftermarket chrome halo projector headlights on the car when I got it, and pilot fog lights also on the car when I got it.

From day one to now.

Sound improvement? Do you have a git or something for us to explore?
[Nexus S Android Development] Windows X:
It should give cleaner sound and richer harmonics without oversampling and frequency locked loop as you get 4-8 times less latency jitter. I asked my sister to try it and she said it sounded more relaxed and easier to listen.

IMO, oversampling is bad as it caused aliasing and distortion of band. Frequency locked loop is more like trade-off as you'll get clearer sound at sacrifice of good transient response.
[Nexus S Android Development] DaXmax:

[Nexus S Android Development] Windows X:
Thank you. To be honest, this is my first coding in Linux and I didn't know it took me 8hrs to prepare env/source. All for changing few bytes of one file lol. Above post should give you some clues and I'm still in experimenting this one so let me test/check more to make sure its stable code for most ROMs/kernels. I may probably try few more on other phones like Galaxy S and Desire HD (does it have ICS source?)

[Nexus S Android Development] Windows X:
Glad to hear that. lazy isn't the best governor for sound quality wise though. Some powerful governors give fuller and more coherent sound. Let me know if you find something more to do with.
[Nexus S Android Development] bedalus:
There is no such thing as 'latency jitter', they are two separate things :). Latency is the delay caused by digital sound processing as the CPU cycles take time. A buffer is used to keep this delay constant.

Sampling jitter is caused by inconsistent clocks either at the input A/D stage, or the output D/A stage. Since we can't do anything about either of these stages without modifying the hardware, there isn't much we can do to improve the sound quality, apart from use better headphones and get the EQ right.

A smaller buffer is not going to affect sound quality, it will just mean the sound hits your ears a few milliseconds earlier.
[Nexus S Android Development] DaXmax:
Err, what governors has something to do with sound?
[Nexus S Android Development] Windows X:
Refined setups will readily reveal sound quality changes with changing latency. Its best to use lowest stable latency. A good programmer would argue that latency is a non-issue for playback. "Just set it to highest level as we get less context switches which is more efficient...". This is not correct for best sound quality.

At a software, firmware and hardware level, PCI prefers small payloads.

"Latency jitter" as in variations in latency was thought to be the cause for why latency affects sound quality. This idea has been scrapped.

From a Jitter viewpoint, when a soundcard's buffer is populated (whilst the other buffer is converted to SPDIF or whatever), there's a burst of electrical activity. The idea is to keep this burst as short as possible thereby reducing interference to the soundcard's XO, i.e. reduce Jpp. We achieve this by setting latency to the lowest possible level. Of course, using such a low latency would mean more frequent buffer loads. This is the ASIO frequency (or ASIO Hz). At 32 samples latency for 96k output, ASIO Hz is 3kHz. This is now periodic in nature and is digitally induced. We now have Periodic Jitter - the worst kind which exists for all digital playback systems. ASIO gives us control over this.

Higher ASIO Hz is preferred and you definitely want to avoid anything less than 1kHz. Why? A soundcard's PLL or PLLs down the chain will be able to further reduce this periodic jitter as the frequency is likely to be above the PLL's cut-off.

From: http://www.cicsmemoryplayer.com/index.php?n=CPlay.ASIOLatency

I wouldn't say cics saying no means no though. But I found his paper from music server research looks promising to give it a shot myself and I found it was true from my own tests also.
[Nexus S Android Development] Windows X:
http://www.cicsmemoryplayer.com

From cics' research, it seems many things we believe it won't affect audio/video performance are misconceptions. Well, for mobile it didn't cause significant result like PC though so you can overlook it but it's worth a try to change stuff with NSTools and such. I used to disagree stuff like his experiments just like most people. Then I took music in the ears.

Is there way to apply this mod by just editing smali?:)
[Nexus S Android Development] Windows X:
No because this isn't java compiled from framework. It's pure C++ code modification not Java to native code.
[Nexus S Android Development] apatal:
Looks promising.....if it actually works. I'll try it out later by flashing it over a Voodoo-less kernel like Franco's r4. Will let you know how it goes. Thanks for your work. Cheers!
[Nexus S Android Development] Windows X:
This works better with voodoo and I have Air Kernel 4.0 (Voodoo enabled) included. Flashing another kernel or additional tweaks may not work as expected. However, it still works better even without voodoo. I'm just little worried about performance/stability optimizations on other kernels/tweaks.
[Nexus S Android Development] apatal:
But I thought this already have the Voodoo sound module included? Doesn't that mean it should work fine for non-Voodoo kernels?

I do understand your point though, about not being able to guarantee optimum performance once we use the mod differently than was what it was originally intended for.

Cheers!
[Nexus S Android Development] DaXmax:
By the mean by that is, kernel is built with the mod. Its not a patch...
[Nexus S Android Development] kong:
FYI, I'm no sound expert or have any experience in sound processing at all.

From what I read in the first post, there is no change to the kernel. He just modified the audio library (/system/lib/hw/audio.primary.herring.so) to have less buffer size and latency.

I tend to believe that governor choice can affect the sound processing e.g. using different sampling rate to switch between frequencies.... but if you use Performance governor then this factor could be eliminated, I guess :P

BTW, I flashed the zip and tried listening to some FLAC files. Couldn't tell that I noticed any improvement. Only the sound is louder than when listening with default T132 setup -- but that could be just because headphone_amplifier_level in Voodoo was changed.

Anyway, thanks for sharing your experiment... This may lead to something very powerful in the future :D
[Nexus S Android Development] Alberto96:
Delete this, sorry :)
[Nexus S Android Development] :
The source you've quoted doesn't paint a complete picture.

Set it to a level where it doesn't glitch. But keep it low so you don't have to wait a lifetime before you start to hear playback. But that's not jitter, and has no impact on sound quality. Where does the author get this unsubstantiated assumption that latency affects sound quality? The two aren't connected.

This is just nonsense. It's not even possible to change your latency setting while playing audio. Unless he's trying to say that resetting the buffers size alters jitter, which is also nonsense. Sorry for the impatient tone, but I used to work as a sound engineer and I've no time for snakeoil.

We're not using any interconnects here...

So lots of short bursts rather than one long one? What on earth? Interference is only an issue in poorly designed interconnects.

The ASIO frequency? He's making up his own terminology.

I've never heard of periodic jitter, so claiming it is the 'worst kind' is hard to swallow. And I don't follow his argument about how the frequency that a buffer is filled is going to induce systemic interference. We're not talking about a huge power surge and associated EMP here. And interference and jitter are two different things anyway.

I'm pretty sure this is nonsense too, but too tired to research it right now.

Again, apologies for the tone, I care a lot about good audio, but mobile phones

will never be audiophile devices. Also, I'm really tired right now. :)

could you provide a graph ?
[Nexus S Android Development] wildestpixel:
This all rings true of the arguments posed by Supercurio himself.

I'm not going to debate on this although I do come from a background of many Vestax controllers and many different audio interfaces. Years ago when Intel defined the HD Audio codec specification (Azalia) to replace the awful AC'97 I had a lot of hardware level involvement on motherboards and plenty of prodding with a silly-scope.

And very quickly to cap - I don't get the theory behind this in the same way as Bedalus.

From explanation in

https://github.com/peteralfonso/pla...mmit/a1fee1161f403d8fba66a7d76d246a1c785a6d3c

So having less buffer size means more round to send buffer. It could be more responsive at the expense of power and resources consumption.

Anyway, it seems this patched library doesn't have direct dependency on specific devices. I'll try and see if it could be generalized patch for all devices.
[Nexus S Android Development] ADJack:
I tinkered with this yesterday. I can't say confidently what the changes were because I feel they may be placebo. But I'm fairly sure that the volume level was different. In terms of quality, I cannot tell for sure - only way for me to tell is to have 2 phones; one with tweak other without. But if this can be tested on paper that would be cool. Looking forward to future updates.
