Camera testing buzzing noise - Galaxy S II Q&A, Help & Troubleshooting

Hi it wont let me create a thread in general section so im making it here... Can anyone test their camera for me, mines makes a crazy buzzing noise when it gets hot heres how... Leave video camera with flash on for 15min or even use a flashlight app you can even play a high graphics game example mass effects/nova 3 when the phone gets hot open the camera app if its not already open record a video again wiv flash on, tap the back of the phone/camera it goes crazzzy...loud buzzing noise only happens when phones hot and camera app is open..can even happen without recording video just by tapping the back on the phine with camera app open!!!!

*audio recording clicks/pops*

The speed of the internal storage? Like what equivalent to classes for sd it would be?

nov 12: edited the title since this turned more into a discussion about the audio pops and clicks from the VIDEO CAMERA and VOICE RECORDING apps....may be a codec problem!? EVERYONE has this; let's bring it to HTC's attention! i currently have an open ticket iwth the escalations department to which he called me, and i sent him the links to my youtube showing all of the clicking noises in every video marked HTC Rezound:

let's bring this to their attention!!
Use Antutu or another bench, they tell you R/W speeds. About the only thing they are good for, lol.
sweet thanks...yeah i wondered what the speed is for that..figured maybe making videos on a faster speed may get rid of those pops and clicks..however i just did, and it didn't do **** lol
I haven't recorded any videos on my Rezound yet, still, lol.
I did a few more guitar videos today.. Same clicks and pops. Meh

Is it while focusing or zooming? Or is it just the sound is too loud entering the device?
Might be when sound is too loud. I don't notice any focusing going on but that's a damn good idea. I think we can turn auto focus off in video too. It's like a digital blip noise so i don't know what exactly it is
It also did it with an acoustic, which isn't loud at all.... So i think it does it irregardless of sound

I recorded a quick video of my puppies play fighting in my livingroom. The only "noise" I hear is my phone vibrating and the notification of Kenny Powers "Dollar Dollar Bills Ya'll" when I get a text mid video! I am pleasantly surprised by this though! My X2 would stop recording if I got a message of any kind. I like that this records right through it, so you can just put it on silent and record away!
hmm...yeah, here's the noise i hear:

very noticeable here; did this yest
I hear it... weird man. My phone doesn't ever do that, that I know of. I got a friend who can play about as well as you. I will see if he will let me record a clip to compare. Hopefully it is only hardware on your end.
hopefully its NOT hardware! hahaha i don't, wanna replace this thing
http://www.youtube.com/watch?v=b4aTQctjEm8&feature=youtu.be
there's the dog playing in the yard..it seems to be a noise that only occurs when clipping happens....but it takes little to NOTHING to clip the audio..i bet it's a noise cancellation issue
Well, if it is hardware then it is good because it isn't wide spread.

Do me a favor, play some loud music on a stereo and see if it does the same thing, that way I can try to re-create your problem on my end with the same method.
I just did a test of this, and mine makes audible clicking sounds whenever the camera is refocusing. You can test it on your device by getting a contrasting shot (use mine as an example) and then tapping the screen between the two points to make it refocus on the point you select.
http://youtu.be/gjmqDC9MLYc
sometimes when it refocuses, it doesn't make a noise at all (ideal). So maybe it's some software params making the lense try and adjust further than it can, or it might just be a camera problem..
eitherway, i don't take videos very often, so won't worry me too much.
That sign in the back gave me my laugh for the day!
that sign rocks hahahaha
but those aren't the same clicks i'm getting. i shall test with loud music playing and by pressing to auto focus...
CAN WE turn off auto focus on video? i know we can on pics, but howbout vidoe?

notice at 1:01 when i goto the subwoofer you can hear the squink noise destinctly..i wonder if low freqs are what make it squink?

Click to expand...
Click to collapse
Those clicks when the video starts while it's trying to focus on your laptop screen are the same as mine too.
I can't help but think the pop I hear at 1:01 is the exact same sound too...
Best test for the audio would be to lay the camera face down or something and hit record, and see what it gets.
Edit: on second thought, I think i'm hearing both types of clicks.
I wonder if the regular voice recorder has this problem too?
Edit2: sure does... i have a steady pattern of clicks on my voice recordings when recording my piano. they're like every ~2.5 seconds... and very predictable. especially on some of the youtube links posted earlier..

Maybe it's just a codec problem?
When i record as AAC_LC in the voice recorder I hear the digital blips.... not so much with AMR, but it's a less quality codec I think.
Edit 3: OP you should change the title of the thread so other forum members drill into it, i'm sure there's someone who knows what might be going on better than I do.
But from my vantage it sounds like a codec error. Hopefully resolved by an HTC update, or a future fix when we get perm root.
The video clicks during focusing I've researched a bit, and it may be related to how the software handles the camera functions, and could also be resolved with some updates... fingers crossed.
nice, good call. updated the title!
I have been unable to really root out the issue here with the camera lense making that noise as it tries to refocus... I'm assuming it's software controllable so some parameter in there somewhere would fix it. Guess we'll have to wait for root and a custom Rom!
anyway, I've tried some different camera apps, messing with the autofocus to see if it makes a difference, and they still all seem to make the auto-focus noise. I haven't found any market apps that do video recording however. Does anyone know of any?
I'll dig in the SDK a bit, but I bet the autofocus fuction is part of the ROM and not the software using the camera. In which case, different software won't make a difference. Just sounds like the lense is over-reacting while recording a video, causing the clicks in the video recording.
As for the blips, I'm definitely convinced it's a codec issue, since it also happens in the voice recorder which (I'm assuming) might be use the same codec as the built in video recorder app for the audio.
Case still open for now...
man, i'm having a hard time finding an app that does video, too. i downloaded the MIUI camera APK i found on here somewhere, but the video recording was like 1fps lol it was terrible, so i didn't even bother.

Microphone issue

Hopefully someone can help me with this issue.
When using the stock "Soundrecorder" tool i can record the first two seconds just normal yet right after that the recording-volume just decreases so fast that after one more second i cant hear anything anymore when playing back the recorded sound.
When i stop and record again same thing happens again. This is quite the issue also in Skype since ppl can hear me the first seconds and right after its like i turned the micro off.
Trying one thread bump again to get a respond from someone with similar issues before i hit a factory reset.
The problem is really something i have not seen on any other android device i own. You start recording speech and right after 2 seconds the rec-volume is NULL.
I mean there aint any settings for the sensibility the built in microphone records right?

[Q] Got phone makes clicking sound

Got a phone for my cousin,
when it came and I turned it on I realised when I put on camera and hit focus it made a clicking sound.
But thought cause I click the focus icon on screen
think i took some other pics without the focus but didn't hear the sound
my cousin now says that every app he operates the phone makes a clicking sound.
Has anyone else ever experience such?

[Q] Back camera makes weird noise

Hey guys i recently noticed that when i open the camera app or snapchat and switch to back camera the camera will make some weird noise like an engine and sometimes it just sounds like a "click" sound. If i open the camera app and it is already on the back camera it still makes a sound, so not necessarily when i switch. It kind of like as long as i start the back camera some weird noise will appear.
Does anyone else have this "issue", is it an issue, should i replace the phone etc.?
Appreciate any help
Same thing is happening to me. Did you got your phone replaced?
I got the same thing here. Doesn't affect video or pictures so I could care less

Internal audio record gone after update to emui 9.1...

Hi guys.
My JSN-L22 received an update tonight. I'm now on emui 9.1.0.217
I went to record a game this morning and the internal audio record option is gone.
The tick that used to be there to click it is nowhere to be seen, there's only the mic icon.
If mic is on it records mic, if it's off it's completely muted.
I've recorded internal audio around the 29th of July so it definitely was this update...
WTF I'm pretty livid tbh. I loved that inbuilt feature!
But I don't see any news about it on the internet, so I wonder if it's only me?
Please tell me of some 3d party app that will let me do this again :/ Does Mobizen internal sound record even work on the 8x? :crying: Goes without saying I don't have root >_>
Internal audio record is not gone
It's not gone actually. You just have to make sure that the mic icon on the upper left hand side of the screen is turned off. The system should automatically record the game sound.
In fact, This update allow us to listen to the game sound while recording it. While in the previous versions, the game sound is muted when you're recording.
