It is nice to see OIS on the Note. I assumed it was hardware, but I noticed the option for stabilization becomes disabled when shooting 4K video. This led me to believe it's software and performing stabilization via software for 4K would be too much for the phone. If hardware, why is stabilization turned off for 4k?
Pretty sure it's hardware since that's how it works for Canon (IS) and Nikon (VR) lenses.
Pentax has it as part of their camera bodies instead of their lenses, but it's still a hardware feature.
And it could be that they allow OIS to be deactivated during 4K video since if the phone is placed on a tripod, the OIS can get in the way, but I'm not sure tbh.

I know there is no optical image stabilization but what software stabilization ? Its more handy for video than stills for my use.
It is using optic-flow-based image stabilization
That is about all I know.
I don't understand the hype with optical image stabilization. The Note 5 has it, and it's so bad that it makes video recording almost unusable. Basically it creates this really nasty motion-rocking effect that distorts the video, ruining the shot.
Optical image stabilization should stay in DSLRs where the lens is decently sized.
I really hope the Nexus 6P does not include it, or if they do make a toggle to turn it off for video.

I think it's been shown that it helps with night shots. Less blurriness.
I found this a few weeks ago while looking for details on the new fangled closed-loop actuator. It was from a presentation given by Sony in Taiwan. It's in Chinese (use Google Translate), but the slides are in English.

The closed-loop actuator should be just used to detect the motion direction for the video software stabilization, not really acting like an OIS to actively cancel the vibration.

It definitely cancels vibrations. Check out this video. The dash of the car is vibrating like nuts, but the video is buttery smooth.

What's not clear is whether the actuator is being used to stabilize picture taking. The only thing I've read is that the actuator helps make the auto-focus faster and more accurate for pics. I assume if it were software-only, then the frame would be cropped, and the border would be used to "adjust" the image. I don't think that's the case... could Z5 owners verify?
I believe Timaustin2000 said that SteadyShot doesn't work in 23/20 MP manual mode (please correct me if I'm wrong), which would lead me to believe it is disabled for 23/20 MP SA as well. That would explain why some pics look "smudged" in 23/20 MP.
Any Z5 owner want to comment on how SteadyShot is working for pics?

The video enabled the Intelligent Active Mode for software video stabilization which helps from the actuator but isn't an OIS still because it does cut the FOV. If it is a truely OIS, Sony will advertise it. Actuator isn't any new stuffs. Sony been used such actuator for a long long time in some old DV tape camcorderor small FHD camcorder like TG1(which I had one).

As a result, the volume of entire optical system including the actuator is significantly reduced, namely "a 75% reduction from the existing models," according to Osano.
The steadyshot won't actually work for photo bcoz both 23MP/8MP got the same FOV. The actuator is mainly designed for detect the direction and hence, might got a bit helpful for video focusing as well.

Ah yes, you're right. I remember seeing that the FOV is narrower when taking video, hence the "hybrid" stabilization. But it still doesn't clarify what SteadyShot does for pics. I had assumed the actuator system was derived from the Alpha series, which is sensor-based, but it might not be the case. Looking at the block diagram, the actuator sits above the sensor, nor does it use a floating lens of a traditional OIS system.
It looks to me that the actuator is used as a shock/shake suppressor rather than precise lens compensation. Not enough info to go on.

Sony said they are considering to implement OIS in next year. The actuator comes with the Z5 lens but the Sony TG1 actuator is also located in the optical system. It needs some of shock/sharke suppressor to calculating the direction but if it is an OIS, it actually need a much larger space for the lens or sensor to "move". On my S6, I can see my lens moving on the back, it is a lens-shift based OIS.
I've read the video stabilization option is software related and some have turned off on the s6 to only utilize the OIS hardware. What is the best setting for our S7 edges? My last phone was the S4 this camera is leaps and bounds over that but I've noticed if I shake the phone a bit while recording video is does seem to show that in the video on playback. I've never owned a phone or camera with OIS so is OIS just for small hand tremors or something ? Thank you!
ois is for stabilizing the photo or video but it's not completely fool proof. You can take 2 videos one with ois on and another with it off. In my testing the one with it off is more shaky while the one with it on makes the recording look more fluid if that makes sense. Shakes are still seen just not as jerky or harsh.
I personally like it off (just OIS, no EIS). Turning software stabilization on did make the video slightly smoother, but it also caused some edges to appear odd (fuzzy / jittery).

Thanks Buddy
Also wanted to know how to change these Pre set options
I have pointed it with the Red Arrow
I have been wading through all the YouTube videos trying to get an idea if the ZTE Axon 7 will be my next phone and I find this
I am totally suprised at how good the OIS / EIS is working and it looks to me very similar to the S7 and iPhone 6s+ stabilisation.
If anyone has the phone please let us know what you think and if you can post some video capture in 1080p that would be great to.
The autofocus seems lost too often in this scene...

It does. Software issue so could be fixed ? But how about that ois
How many axis OIS and EIS are these?
Is EIS part of camera unit or is it ZTE development?
Does EIS operate in case of 4K and/or 60fps?

I don't know as in the UK it's still not released yet
OIS is hardware and EIS is the electronic image stabilisation in the software. It looks floating like an iPhone or Samsung s7 but I would compare it more to the iPhone 6s plus but as someone already commented it is hunting for focus too much. Let's hope we can lock focus at least until they release the promised updates.....lol. Zte updating a phone. I think we will have more luck with custom roms if they unlock the bootloader!
The OIS is performing so well wow. Some of the other videos show really bad performance, wonder if its part of a new update?

OK it is clear that EIS is software solution for the problem. I don't know too much about phone cameras but look at this article.
http://www.androidauthority.com/sony-announced-imx318-cmos-image-sensor-673495/
It is just about camera device alone and it says "the IMX318 supports 4K capture at 30fps and features electronic image stabilization to reduce camera shake and lens distortion", which means for me that software is included in the camera itself. Or?
Regarding axis I read the following meanwhile "The back of the Axon 7 is where you will find a 20 mega-pixel dual OIS rear camera".
http://www.gizchina.com/2016/08/08/zte-axon-7-first-impressions/
I suppose that dual is the number of axis because A7 has only one rear camera.

The phone has both OIS and EIS, that's why the "dual OIS" part should say "dual IS". Both OIS and EIS mechanisms are built into the sensor module, but while EIS is performed on the sensor, the OIS is performed by the SoC taking the reading from the 2-axis gyro (haven't seen any specs indicating more than that) and driving the (most likely VCM) motors in the module.
The auto-focus hunt in the video is too much, hope it can be locked, it made me nauseated
No info on what sensor it is now that is interesting. Knew the glass would be cheap but that's the way it goes on a cheap phone.
Overall looks quite good to me compared to the op3.
The pocket now review found that OIS is not so good and if you enable EIS, it gets worse. In the end they called it ambitious but flawed.

My main problem with the camera are hand-held 4k videos that would require some shake reduction.
I understand that the latest US ROM may have better shake reduction: Camera
Camera image processing algorithm enhancement, like anti-shaking, HDR etc.
How do you record hand-held 4k videos? Do you use a third-party camera app with shake reduction?
Thanks.
The stock camera app seems to work and handle shake reduction pretty well.
