i'm very disappointed with 4k video - Samsung Galaxy S8 Questions and Answers

Hi guys, have i got a faulty S8? I purchased it 24 hours ago to upgrade from my S5 , and mainly for a better video camera experience.
The S5 gave superbly sharp 4k video in all but the dimmest lighting conditions, though it was very jerky and showed a lot of rolling shutter jello effects.
So I replaced my S5 with the S8 after reading reviews and watching video samples, but with my S8 set to UHD, i'm finding the video looks more like HD as it's no where near as sharp as the S5
looking at grass and leaves in early evening light, they look mushy, whereas my S5 showed every strand of grass pin sharp.
So could it be i have a bad camera, or is the S8's UHD not as sharp as the S5?

I'm coming from a Note 4, and I feel the same way. I mainly bought my S8 for the great camera that was touted, but my Note 4 had much sharper pictures by far. I will make a post with some side by sides eventually comparing the 2. The S8s pictures are more soft around the edges, not as much detail, and with high contrast areas (such as taking a pictures in a car of the gauges, black with white letters) there is a lot of bleed from the white over the black, like a fuzz. Video also seemed better on the Note 4.

This is very dissapointing as I bought my S8 primarily for a 4k pocket size "camcorder" as my S5, though pin sharp, makes 4k video's too shakey and with constant focus hunting.
The S8 was touted as the best camera ever, next to the Iphone7 and google pixel, so naturally i thought that camera tech should have improved since 3 years ago when i bought the S5.
The biggest improvement is that 4k is much better stabilized and very little rolling shutter, but the image quality is just about the same as FHD, the sharpness if the S5 in 4k video is so sharp that i see every pixel is used individually on my 1080 computer screen, yet the S8 sharpness close up on my 1080 screen, you can see several pixels are blended as one colour, this is on the high detail items, as its very dissapointing if your a 4k fan like myself. I really don't understand why they rated the S8 camera so high for 4k, but having said that, I have seen a few Youtube videos of S8 4k footage and it does look really good, which takes me to my next question, what sensor do we have, as apparantly there are two different sensors fitted to S8 models, a Sony or a Samsung sensor, could it be that one is better than the other?
So i'm guessing theres no point it taking the phone in for repair?
I will try and upload comparison screenshots if this site allowes for this.

Post the video on youtube of the s5 and s8 as unlisted.

Problem solved!
Perhaps I jumped in too soon to report the problem of my 4k video, it turns out that the media player that i'm using on my pc is MPC-HC and this player automatically zooms in to a 1080 crop of the 4k video, I found this out by accident when I noticed that the playback looked more zoomed in than i remembered shooting the scenes, so by pressing the number 1 key on the numeral keyboard, the video zooms out to its full frame and now i'm happy to say that the videos are pin sharp from the S8 too.
Funny thing was that the S5 4k videos played at full frame on MPC-HC without having to zoom out and thats why i thought that the S8 was faulty.

Testing GRam and Camera

Hello Ya'll,
So I recently purchased the G2 from Verizon and a few things to note about the new GRam and updated camera with OIS. Maybe it's supposed to stutter/lag in this setting but when I play The Simpsons: Tapped Out, I see a noticeable lag when swiping across my screen in certain areas. It slows down noticeably as if it's struggling to process the graphics. I'll have to try it with more games but that's my 1st impression unfortunately.
For the camera, it seems that any sky or even upward shots with the sun just even slightly in the FOV destroys the picture. The white overtakes the picture and everything seems overexposed. If this is normal for a smartphone camera then no complaints. But just even taking a picture out my window without the sun seems washed out and I can barely make out the trees. The 1080p/60fps recording seems to suffer the same problems as the camera when indoors. The ceiling lights wash out everything and it doesn't even resemble anything close to 1080p. Maybe I have a defective unit?
If anyone else is experience this or I'm over estimating the phone's capabilities, please let me know so I can be content. Thanks in advance.

Camera exposure and response time

I find the camera takes darker pictures, especially in low light, compared to Note 5 (underexposed perhaps? Not a photography buff at all . Also, the snapping pictures in general seems to be slower vs. Note 5.
Any suggestions?
I currently have both 6p and Note 5 and truly find the Note 5 to have an all-around better camera. 6p but bad by any means, but tough comparing to Note 5.
Been comparing to a friend's note 5.
The note seems to overexpose a tad in lower light.
6p seems like it's a tad darker around the edges, but for the most part is a better match to what the eye sees.
Hdr+ balances everything out, and should be used whenever possible - like always.
It works wonders. This coming from an amateur photographer, well, I have been paid for my work, but I still consider myself an amateur - even after 35+ years of playing with cameras.

Agree with your assessment. Note 5 can tend to overexpose slightly in low light but overall I find Note 5 pics to be a bit clearer in low light. Even with hdr auto on both. Also agree the 6p tends to be darker around the edges. Biggest concern I have with 6p is length of time to focus/snap picture. Seems far longer than Note 5...

Only been playing with the new 6p for a couple days, but so far it seems pretty instantaneous.
Point, click, there's a picture - and in focus.
Been very very happy with the camera so far.
With HDR off the shutter is crazy fast, pretty much instantaneous. I keep auto HDR on because the HDR on this phone creates truly amazing results. If your phone is shooting HDR there is a little bit of a lag when taking a photo but not terrible. I'll take the slight lag of the HDR because the increased image quality far outweighs it.
As for underexposing images, I don't think there is any issue there. Keep in mind that the screen on the 6p is calibrated very differently than most devises. I notice images look underexposed on my phone's screen but on a computer screen or another device they look fine. I have adaptive display on so it is dimming the screen making the image look darker than it really is.
Look at the histogram of the photos if you want to see the dynamic range and the actual exposure info. In low light my 6p is very good figuring out the exposure. The histogram is obviously on the darker side if I take a photo in low light but there isn't any clipping at all under reasonable low-light. In extreme situations, like a photo in the middle of the night with only one light source, then the shadows clip but they would with any camera. What is really impressive is the lack of noise!! Usually when you have full black on a cell phone pic you get a ton of noise but the 6p is pretty good at just letting it go black rather than trying to overexpose.
The dynamic range with the HDR on is really impressive. Even extreme contrast like indoor photos with a bright window in the background won't clip in the highlights.
I am having a blast testing the limits of this camera.

Can you please explain to me the slowest shutter time of the nexus 6p with a third party app? Currently I have a Oneplus 2 and I can get up to 30 seconds which is a lot. My Oneplus 1 even had 60 seconds. Can I have these values with the nexus 6p or through a mod?
Thanks

HDR performance battle: Z5 vs. Galaxy S5

I've done some real-life tests of the HDR function, which has been very good on my Galaxy S5. Below are the S5 vs. the Z5. On the S5, HDR is easy; on the Z5, Superior Auto doesn't have HDR, but there's an HDR setting in Manual mode. The best I could get with the Z5 still looks (to me) worse than the S5, because you can see less detail, even if there's more light (you can brighten the S5 pics if you want, but you can't extract more detail out of an overexposed scene).
In the lamp+TV scene, look at the sine-wave like detail on the lamp cover. The S5 shows it without problem; on the Z5, you can barely see it if you zoom in, due to overexposure.
In the food + window scene, the Galaxy S5 wins again. The detail in the food plate is better, the spoon is less overexposed, and the foliage in the upper left corner is also better exposed.
Notes
1. Originals can be found in my Flickr album comparing the Xperia Z5 vs. Galaxy S5 camera performance.
2. Also, keep in mind this is a previous generation Galaxy S5. The S6 probably has even better picture quality.
3. The Z5 photos are badly distorted in the corners - the food plate looks oval, and the lap cover looks elongated too. Read more in the Z5 distortion thread.

Poor Low Light Video

Since upgrading from my Note 4 I've noticed that the low light video is terrible on my S7 Edge. It's like the lens itself is having trouble adjusting to low light which didn't happen at all with my Note 4.
As an example if It's very dark and the light is on there is a shimmering when videoing objects more than 3 feet away and it makes the auto focus go mental. I thought it might of been a fault with the camera/phone but my other S7 Edge is exactly the same and they were manufactured a Year apart. I've tried dropping the FPS to 30 from 60, unticked the video stabilisation and checked the memory card but nothing works so now I'm faced with selling it and buying something that performs better movie capture in low light conditions.

Moto G7 worse the G6 phones?

I have some concerns about the new Motorola G7 phones particularly:
Screen - The screen tends to have a blue/cool tinge, the overall display calibration is "off".
Camera - Colours can be washed-out, zoom has many artifacts & noise and poor dynamic range at night. Stabilization needs a lot of work (for both front & back) and overall sharpness/detail/colour could be better.
Does this mean the actual lens is of inferior make & quality?
Will a GCam port be enough to compensate for the otherwise poor camera image quality?
Need help. Thank you.
Unlike G6 and Z3 Play, you cannot change the color temperature.
However, you can install CF Lumen if yours rooted.
I did it on both G6 (compensate green) and G7 to keep the color temperature consistent.

For the screen, I usually use night light. Corrects it easily
I know our maintainer is working on a gcam port last I knew. If you have twrp you can always flash gapps with gcam
But to answer the thread title: no its not worse with more RAM, more storage, better SoC, etc than the g6

I haven't noticed where the screen seems to be blue, mine looks fine to me and other colors seem just fine.
As far as zoom goes this device does not have optical zoom, so of course it's going to be bad. May as well take picture normal then crop, it achieves the same thing. I think stabilization is amazing, definitely a lot better than the G6.
I use the Google Camera port and it definitely takes good pictures but I haven't noticed and differences between them. Night sight is amazing too.

I have a replacement screen and the video looks fabulous over my g4. That died. Get a case or you're going to be looking on eBay for a picture of the exact same ribbon cable printing for about 29 bucks. If the photo doesn't show same printing on the black, don't get it! Real on left, not gorilla glass 3 on the right. I used silicone on the very edges instead of getting that 3M stuff because this model of phone uses the REALLY thin stuff. Did my pic upload?
Absolutely NOT! I feel as though the G7 is USA's G7 Plus with those specs. Lenovo really screwed up not bringing the G6+ to the USA last year. My OG Pixel was trashed (throwing it at a concrete wall) and my closest option to purchase an Unlocked Device was at Walmart. All the devices they had on display were last years models and the very non-knowledgeable sales Rep didnt know what was in stock, so i said forget the display models and lets head over to the storage box and see what there is to choose from. When he opened the box, a bright light shined over and they're were about 8 G7s (non of which was on display). "Oh we cant sell them yet" WTF??? Go I got stuck taking a G6, but I was NOT a happy customer. Contacted Walmart Customer Support and 2 days later i returned the G6 for my awesome Moto G7.

I do repairs so I see complaints about color accuracy on devices all the time, but you can take devices straight out of the box and there will be variations because there is an acceptable tolerance otherwise they'd be throwing out so many screens. The ones that tend to get the most complaints are the ones at the edge of the tolerance.
3m tape is awful for screen replacement, we use the black Tessa tape, it's super sticky and doesn't like to let go.
