I need to know if there's some noise reduction settings which can make the pictures more clear and detailed and without noise

in settings->phone one can turn the noise cancellation for phone calls on, off or set it to automatic. what does automatic mean?
"On" refers to constant effort on the phone for noise cancellation, provides the best quality/effect.
"Automatic" means that the phone will sample the noise level at the beginning of the call and then apply that as the level of noise cancellation for the entire call.
The "on" option provides better quality but will drain the battery faster as it requires more processing power. The second one will provide some noise cancellation but not as good, but on the other hand it will also be the best middle point between noise cancellation and battery usage.
"Off" obviously just means off and won't require any extra effort from the processor and the battery.

this means that if i start a call in my house and go outside (there is a noisy street in front of my house) the cancellation does not get activated, right?

Where did you get the information on energy consumption from? i checked the manual, unfortunately it did not contain any valuable information about the noise cancellation.

it does not sound plausible to me that there is a relation between the aggressiveness of the noise cancellation and the requirement for processing power.
From page 53 and 54 of the manual:
To turn noise reduction on or off
When you are using the earpiece and not the speakerphone during a call, you can
tap Menu > Noise Reduction On to reduce ambient noise if the other party cannot
hear your voice clearly. When noise reduction is not needed, tap Menu > Noise
Reduction Off to disable it and save battery power.
You can also turn noise reduction on or off in the Phone settings. Tap Start >
Settings > All Settings > Personal tab > Phone > Advanced tab and then select
one of the following settings in the Reduce noise in phone calls drop-down list:
Automatically. Analyzes ambient noise only at the beginning of a connected
call and applies a certain noise reduction setting based on the detected
noise. However, when you move to a noisier environment during the call,
your device will not further decrease noise based on your new location.
Always. Always reduces ambient noise during the entire course of your phone call.
Never. Turns off noise reduction.
Notes
• If you want to change the noise reduction setting to Automatically, make sure to do this before starting a call.
• Noise reduction is not used when you have a wired or Bluetooth headset connected.
And actually the relationship between noise cancellation and processing power is logical. When it is on "automatically" it analyzes, then sets a level of noise cancellation for the entire call. If it on "always" or "on" as it appears on your phone, then it is constantly analyzing the noise levels, not just at the beginning. It is processing the noise levels, thereby requiring more processing power
Hope this helps.

damn i somehow missed that paragraph, thank you!
No prob. Now go and enjoy your phone and play with it some more

Buy a Captivate.
Where can I find setting for noise cancellation?
I know that defy has a second mic (near camera has a hole) but I cant find any setting for that and i dont know if it works.
There in not exactly an noise cancellation setting but an voice quality setting.
If you look in settings, call settings, voice quality , then you can select from standard, balanced, bright or extra bright.

thought that was bass control or something..
So will set it bright and see how this behave..
TNX!
The only bass adjustment i can see is for headphones and the external speaker in settings, sound & display, media audio effects , but it`s not for the earphone.

In Cyanogenmod 7 these settings are not visible, does anybody know if that means that CM7 doesn't support noise cancellation?

Thats a good question sir. Can anyone else report a decrease in voice quality on the defy? Does noise cancelling work for normal voice recording too?
It ends up distorted on normal recordings.. Instead you can record in stereo
Is there any way to disable the default and overly-aggressive noise cancellation that occurs when recording video? It's just awful and way too aggressive. Perhaps something in build.prop or other config files? I'm rooted and regularly flash roms, etc. so I'm willing to try anything
Example:
https://www.youtube.com/watch?v=1UVYWq_yZ0s
Have an issue where on most calls I am not heard very well. mic test applications and call recorders all do perfectly but just on calls.
After some digging it seems oppo users had a similar issue and it was caused by the noise cancellation mic. They had some success editing the build.prop file to disable noise cancellation and apparently adjust internal mic volume.
I'm not sure if zenfone 2 has this hardware or not but anyone have any ideas? Currently running cm13 and see now built in options to adjust noise reduction or tty or any such settings.
Thanks
There's noticable noise suppression in video recordings which really affect the audio quality. As much as I like it on phone calls, I don't always record voices when shooting video. The noise suppression really destroys the sound of the environment. Anyone know a way to disable it?

Only way which I think is shooting in manual mode and disable wind filter, and optionally use HiFi audio recording which will enable recording sound track in lpcm.
But I very much doubt that tiny mics of G7 are capable to correctly picking ambient audio of 10-20 dB volume levels. They're too tiny, you should rely on external USB microphone with much higher sensitivity
