P20 Pro video footage dimming issues - Huawei P20 Pro Questions & Answers

Hi
I bought a new p20 pro recently and noticed that, when I record footage, the picture goes dim and dark when i pan or move the scene (even slightly) and the bright, and then dark again. That means that when I play back the footage, the brightness level constantly shifts and changes, making it highly annoying and at times the picture is dim enough that its a struggle to see anything (yes even in broad daylight).
Is there a way to turn this dynamic brightness shifting off or is this a faulty phone?

Hi, did you ever get a reply elsewhere or found the solution somewhere?
My wife's P20 Pro has the same issue. We always accepted the way it is, but only know i thought of finding a solution to it...
Hence curious if you managed to fix it?

TyTN II choppy/laggy main camera but fast/quick 2ndary camera?

So I was playing around and I noticed that when using the main camera it was really choppy, but when I used the secondary camera it was fine, this is for both photos and videos. But out of fluke one time today the main camera had no lag...
So when recording video it's really choppy and photos if I move even the slightest it blurs =/ it's not quick refresh at all.
Using the secondary camera it seems to be very quick and recording videos is fast, not choppy at all.
Any solutions?
After some quick searches I Found this is a common problem...but doesn't answer my question how I got it to work perfect under the same conditions (I was inside the whole time same light conditions)
*shrugs*
The primary camera lags because it shifts into night mode when there is low light so as to get as much light into the lens. Trust me, try going outside when it's quite bright or something and the camera will be sooth as silk
Some people hate this feature though. Not sure if you can switch this "quirk" off so it only happens manually.

That's the funny thing though...it was perfectly fine after this 'glitch' happened haha...in the same light conditions, I'm trying to make that happen all the time

[Q] light sensor / auto brightness

HTC's website says the HD7 has an "Ambient light sensor".
When I have the Brightness settings on "Automatically adjust", I do not see any changes to the screen brightness. Darkness and sunlight have no effect. Curious to know if others are having the same problem or if my phone is faulty.
Thanks
If I set mine to Automatically Adjust on either low/medium or high settings it does adjust according to ambient lighting.
Have tested by holding up to a light bulb on all 3 settings and have noticed the changes.
Thanks for your reply.
A bit more experimenting with a LED torch and it does seem to be working. The curve is not as I would like though. I would prefer the screen darker in darkness and brighter in the light much like my old iPhone. I was in full sun today and the screen still wasn’t full brightness. So with it on High and Auto off, the screen was brighter than when on High and Auto on. So Auto was bringing my brightness down to what seemed to be about medium levels making the screen a bit of a pain to see. I want full brightness in sunlight please. I am sure others will prefer this default setting though, especially those concerned about battery life. Hopefully a future software tweak will allow sensitivity and brightness curve adjustments. Until then, I will stick with the "high" setting and Auto off.
Thanks again.
Have same problem.. Automatic light have no effect on my HTC HD7 (unbranded, with and without nodo).
I totally agree, with me its more of a problem in the darkness. It is way too high when it is completely dark and its more obvious when I switch it from auto to "low" as the screen does become much darker.
Its something with either HTC or windows as my old touch pro 2 had the same problem, in complete darkness the screen would never go lower than 30%...
The light sensor on my hd7 never seems to work..they should implement the way it is on the iphone

Is anybody know is there light sensor available physical on HD7?
Heared on HD2 it work's fine. If it software issue then MS mast fix it.
yea my phones ambient light sensor doesnt work either i see no changes with the auto setting on.
Auto-Brightness works fine over over here - o2 debranded with NoDo update.
When i take the phone out of my pocket/case in sunlight, i notice about 2 - 3 seconds after I unlock it, it gets noticeably brighter and when comparing to "high" brightness without auto it's exactly the saem. Agreed though i would like it to be dimmer in complete darkness (in bed, for example).
I am curious if there is a registry entry that I can change to help with the highest and lowest settings. If I turn on auto it does adjust it slightly when I am inside, but when I am in the sunlight I can hardly see anything. If there is no light also it is still what looks like a medium setting making it very bright. I hope we can figure this out, it isn't a big deal but still BTW I am on TMOUS with NODO

screen not so bright on high

So I noticed that the screen isn't as bright as my Note 4 on high brightness , however when I have it set to auto and I'm outdoors it's night and day difference. It's much brighter under auto, even makes my note 4 (on high) seem like it's on medium brightness . Does anyone else notice this? Anyway to make it bright like this all the time? Because full manual brightness seems like medium brightness compared to other phones. A bit disappointed

That was already discussed in many reviews
Sent from my SM-G900F
Correct.
Manual brightness only goes to something like 450 brightness, but auto can go to 750.
No way to change that. Was mentioned in multiple reviews.
I was at the beach today and everytime I'd look at my screen it would start out really bright and then dim to like 90%. I wouldn't be able to get it bright until I locked it again. It was very annoying.
There is an issue with the auto bright on the Edge. Not sure if it is the same on plain S6 though.
There is? Mine seems to work as I would expect...
Yeah turn auto off and the phone will still dim in dark rooms and bright up if you shine a light into it. Also the Edge does not appear to be as bright at max as the standard S6.

Question Slow motion bug(solved)

Hi, when I use the slow motion , the whole display starts to flicker, but still works. all the other camera modes are fine.
Is that software issue?

The display is flickering while recording, or the video when playing back? I just tried, I don't see any flickering while recording. But if it's in the recorded video, what kind of lighting are you in? I recently tried to take a slo-mo with my S20, and had significant flashing. It was at night, I figured it was due to the LED lighting flash rate being slowed down.

Yes, i would suspect this. Unbeknownst to the average person, LED lights tend to flicker A LOT. They do this at a given harmonic of the line frequency. If you're in the US then the LED will flicker either at 60Hz or 120Hz. Most people can't see this at full speed as the light has a bit of persistence and we're geared to see smooth motion. But, when you slow it down you find that at 240Hz or 480Hz the video is now fast enough to catch the dark patches in between the pulses. So, the video seems to strobe. Not all LED bulbs will do this and those that do won't all do it the same. But, it's there, you just can't see it. Keep in mind when shooting video in other modes this could still happen. At 60Hz or 120Hz video even though it's full speed you are still potentially capturing some frames in between pulses. This could cause a sort of beat frequency to appear. So, if anyone is having that problem when trying to shoot video your options are 1: do it in the sunlight. The sun doesn't flicker. or 2. Get a constant light source. Fluorescent bulbs have greater persistence as do the old incandescent bulbs. Professional lighting will be consistent too. But, $4 LED bulbs are going to SUUUUCK for slow mo video.
Yes. You were right. The problem was the led bulb.
That was interesting.
Thanks guys

Question Screen tint, mostly at low brightness, and a bit jumpy brightness change when adjusting brightness manually – is that a hardware defect?

Hey. I fixed the issue with my new 8gb/256gb Redmi Note 10 Pro from the previous thread, but now I noticed something else. Dark grey areas get tinted rather noticeably at low brightness, but also for some reason at a couple of additional brightness points along the brightness slider; it is more noticeable if 120hz is enabled, and at minimum if Standard color scheme and 60hz are used. Also, it seems the brightness dips about two thirds up the brightness slider, so the screen seems to flicker in brightness when manually adjusting across that brightness point; it's currently night here and I haven't checked if it also noticeably happens during auto brightness at daylight.
So regarding the tinting – I found other people mentioned it, some claiming it is "normal for AMOLED screens", but some RN 10 Pro users then said their screens don't do that and actually the AMOLED screen on my older 9T didn't seem to have this issue.
Regarding the "jumping brightness" – I'm not sure I've seen references to this, but either way it also seems a bit like a hardware issue with how the screen handles different currents.
What do you think? Does it sound like I should ask to replace the unit? I'll also mention I saw Netflix very occasionally stutters, although that would more likely be related to software optimization.
