OP3 VS OP3T camera and others - OnePlus 3T Questions & Answers

Few examples from gsmarena, it looks like the 3T is noisy, and even much more at low light
The ISO is 100 (vs 160 on 3) and same 1600 on low light, but it should be more smooth and sharp.
Why is the camera shots are that different?
Did you notice it on daily use?
There is any other issues on 3T over the 3? (on screen, lagging, battery life, multitouch etc)

HTC One Camera Quality

Hi,
I am considering buying HTC One but there is just one thing that makes me rethink my decision and that is the 4MP Camera. It's a stunning device but I am a bit skeptical considering the low megapixel count of 4 in HTC One. People who have already got the phone and also people who have researched on the imaging quality of "The One", please shed some light on the camera bit.
I know it is good for low light conditions but are the daylight photos good enough if not the best that GS4/ iPhone 5/ HTC One have to offer.
Thanks a lot!

Daylight images are good, but maybe not as "good" as the GS4 purely cos of less details from the lower MP sensor. HTC is probably one update away to perfecting their metering and auto-exposure, but it is still very good and don't forget really really fast
Megapixels are not a measure of image quality. Never has been, never will be. Higher MP just means bigger prints.
The size of the sensor determines image quality. The One camera takes better photos than my 8MP Nexus 4.

That's cos the Nexus 4 had a pretty meh sensor I'd say stock S4 camera app is about as good as modified HoX camera For low light, nothing really beats the One though

Yep, there's been an arms race, so to speak, with manufacturers trying to compete with one another over buzz words, "megapixels" being one of these. The Anandtech HTC One review by Brian Klug covers in excruciating detail the tradeoffs HTC made with the camera hardware vs. marketability

To be fair and honest, I find the shutter speed to take long sometimes in natural and incandescent lighting indoors. I could be sitting at the dinner table and be underneath our ceiling fixture and the picture would be a little out of focus or take too long when the lighting is good. I'm assuming this can be fixed with software tweaks. It's almost as if the sensor takes in too much light sometimes, as I find myself having to turn on the flash manually in some indoor shots.
The positive side, the PHONE takes great pictures in outdoor lighting and even indoor with the right lighting or flash. The colors come out more natural and detailed than my wife's S3. Compared to my old Inspire, the One is 100x better.

I've just been reading a thread on the S4 forum about the lag on the S4 camera. It can take superb landscape pictures in bright light but it struggles with moving images.
The One on the other hand is extremely fast which translates into, for the most part, images with no blurring. And of course low light pictures are far superior which is what everyone raves about.
It really depends what you want from a camera. I, like you, was worried that 4mp would be too much of a downgrade. I then started to think how I actually used my camera. I predominantly take pictures of my family and friends, kids playing in the park etc. I rarely ever view the pictures I've taken on a device that has a better resolution than 1080p and don't crop images often.
A 4mp camera is far higher resolution than 1080p.
As soon as I started snapping my kids, often indoors at dinner times with only fluorescent lighting, I was happy I plumped for the One. It really is astounding how fast it is, and the pictures look lovely on the phones 1080p display.
I would much rather have lower MP. pictures I can use than constantly having to delete blurry higher MP pictures.
Best thing to do? Check out both forums. They are a far more accurate representation of performance than reviews.

Thanks for your reply
Does cropping render the quality very low?
Something to add, is that if you take low light video (night clubs, bars, dimly lit rooms etc) the video framerate will fluctuate between 17 and 30fps, causing it to look choppy. That is the only thing I hate about the One at the moment. Choppy video in low light. The galaxy s4 (and my old s3) do not have this issue

It's just different companies prioritizing different things. The One tries to get in enough light regardless of what it has to do, and that means fluctuating frame rates in low light video. The S3, S4 and Lumia do different things in where they force 30FPS, but in return you get much less light in, making the video darker. But the phone is still plenty new, and we can all hope that HTC would give us an option for what we want, shutter speed priority mode please

Yeah, my issue is that they prioritized something that I'm not used to lol but yeah, hopefully that issue can be fixed
Speaking of the software, if they're gonna include Zoe and all that, I wish they'd provide a Highlight studio of sorts where you can choose the transitions/music/frames etc on the phone.

Currently I have Galaxy S4 and I am thinking of returning it and going for HTC One. The camera is the only thing holding me back. I am super confused.
Could you please direct me to the two forums you have mentioned, being new I am unable to find them.
Thanks for the help.
Is it really 4 Mega pixels??
I thought it was 4 Ultra Pixels??
Surely that different?
"Ultra Pixel" is a marketing name for this sensor, it's still a 4MP device with bigger pixels to get more light and reach the f2.0 limit. Not more only bigger.

It's 4 Megapixel in resolution, but the sensor has more than 4Megapixels. They extra pixels are used solely to capture light, and that's why it has very good low light capabilities
Here's the technical explanation of this ST Microelectronics CMOS Sensor:
The Camera
The HTC One bucks the trend. Based on the 1/3″ form factor of a camera module and today’s state-of-the-art 1.1 µm pixels, all the latest competitive phones sport 13 Mp resolution. HTC has gone with a larger 2.0 µm pixel (confirmed) and a 4 MP sensor. They are pitching the low light sensitivity as a key feature. The device is a back-illuminated sensor fabricated by STMicroelectronics with die marks 58698A. This is the first BI sensor we have seen from ST.The camera uses the IDG-2021 gyroscope by Invensense for motion stabilization. It is a dual-axis gyro with high resolution ADCs designed specifically for optical image stabilization.The secondary sensor is a 2 Mp, 1.4 µm sensor by OmniVision with die marks OV2A9BA. It is a nice secondary sensor that we have seen before in other phones.

The moving video is fantastic with the optical gyro.always smooth videos.
And takes great night shots with longer exposure cause it's easy to get a steady photo.
Why does mine say pn071?

Personally I love the 4MP cam in the One. I came from a long line of iPhones and although they're not perfect, I realized that the most I was going to be doing was hold these images for viewing on my computer, sharing at times. Between the 13MP GS4 and the One I thought it was an easy decision to get the One. I just don't see a need for 13MP size picture files laying around in my computer taking up space.
Now I'm just a normal consumer from a photog perspective. I have a graphic arts background, but I rarely perform treatments or heavy manipulation on my own photos. Take some shots with the One demo at your local store. You'll be amazed at the clarity, especially when zoomed in.
So, i used this device for over a month and so far the camera works great to me, i compared it to other phones i got in touch like iPhone 4s, Note 2 and the S3, video recording is just great on HTC One, it just works better in my opinion, great clarity, good autofocus.
As for photos, it's great, all the photos on 100% zoom look bad, but the HTC One photos look modest at 100% zoom so i don't really think camera is a deal-breaker, it's a great camera the thing is HTC opted for a more revolutionary camera and so far i think they've done a pretty good job.

Front Camera Quality

Hey everyone,
Is someone able to speak to the quality of the front camera on these? I have the HD 8, the front camera is advertised as "HD" (probably 2 MP) and performs surprisingly well.
I'm curious about the quality of the front camera on the 7. It's advertised as VGA, so probably .3 MP. I've used some of the low end Dragon Touch tablets with .3 MP front cameras and the quality is *terrible*, it easily took 5+ seconds to focus on anything. But part of that could be the camera app, the manufacturer of the sensor itself or something else to do with the quality of the hardware.
At $150, the HD 8 isn't prohibitively expensive, but it would be nice to get away with the $50 7 instead. The main functionality I'm looking for is whether it's able to focus in and scan a QR code (version 2 density) quickly.
Thanks!
Just tried it. The front camera takes the photo fast enough, but the image is very smudgy and a bit too high contrast. It's VGA. It would be ok for video chat in a well lit environment but not for much else. If you're one of those 'selfie' types, you'll want a different camera. :laugh:
The 2mp camera on the back seems to be a bit better, but then it should be. Needs to be changed to 4:3 to use the full sensor, as it defaults to 16:9. The HDR mode improves picture quality by a fair margin. Especially unintentionally overexposed ones. As with all these cheapo cameras you will have to hold the whole device still to get a clear shot.
Neither camera is anything special and I'd say both are below average. The 1.9mp camera in my Samsung Gear smartwatch is leaps and bounds above the image quality of this Asus Fire tablet and it's 2 years older with a similar lens size.
The app for the camera does the job but is very basic with few options to change.

From U11 to Honor Play - worth it?

I am on the P20 pro, and one of my family members is on the Htc U11 - for those of you unfamiliar with the phone, it's a snapdragon 835, 4 gigs of ram, waterproof with quite a good camera and quite a bad screen.
They enjoy notch like phones, and they are on a budget. I am thinking of getting them the Honor Play - I feel the battery will be better, so will the screen. The proc is more or less the same; I guess what worries me the most is the camera, or anything else I might not have thought of.
Anyone here can advise with cons and pros? Thanks
Everything other than the front camera is amazing....
Front camera just white washes everything, basically contrast is non existent... And if you are not a white, you will look like an... Em..... irish black person (pale brownish color or something)
Front camera has good quality images but color reproduction is simply subpar... Its a software issue as the same camera is used in Honor 9n n it produces 10x better results!
Overall front camera is 1/10...(compared it with a 2013 galaxy phone n it had better color reproduction than play)
Everything else is 9/10
Well, in my opinion, I go for an exchange for the U11, yes Honor Play is very good at nearly everything, fast and never laggy, I really love the screen, even not being Amoled contrast is really fair, it's a beautiful piece of hardware and software, but 2 essentials points for me : camera quality is really lower, and it's not waterproof at all (a friend had his Honor Play felt into water for like 3 seconds and sound died + screen flashing now). For the price it's very good, but not sure it worth it to change from U11 which is, still in my opinion. But yes battery is good with some easy tips, it can survive easily a good day, and before the last update I was at 2 days for average usage.
Based on what I saw, U11 and G6 were at pretty same level in camera (but U11 much expensive, it's why I didn't take it), and I can say I often regret my G6, so now if waterproof and picture quality is not that much important, go for it with no doubt
There is no waterproof smartphones out there in the market. There are only water resistant phones and that shouldn't be an issue if you are not IP67 -69 enthusiast. The camera might not be on per with the best out there but the quality is not that bad. Indeed, I get good results from it during the day .
In my view I would go for Honor Play as the first choice and it's new compared to U11.

Pixel 3 worth upgrading to Pixel 5?

Hi guys,
Have a question for those who have access to the new Pixel 5. I'm currently using a Pixel 3 and am considering an upgrade to the new Pixel 5. But I'm concerned with the Snapdragon 765G that they have decided to put into this phone. From my understanding the 765G performs slower when compared to the 845 found in the Pixel 3. And even the camera sensors are the same between the 2 phones. So I'm just wondering if the upgrade is worth it or if I should wait for next year.
Has anyone had any issues when it comes to the processing speed of the 765G?
Obviously very early doors to try and compare them but...
I have a pixel 3xl and the pixel 5.
Feels the exact same for everything I've tried with it with a couple of exceptions.
Pixel 3XL is slightly quicker opening the edit menu on portrait shots.
Pixel 5 is definitely holding more apps in RAM so less time spent relaunching apps
90hz screen is lovely and makes it feel like the pixel 5 opens and processes things quicker. In reality it's taking the same time, just looks better doing it
Not tried anything more challenging yet like color grading 4k video yet, but I'll try it out later
Pixel 5 camera is better in low light, especially the portrait shots. The wide angle also looks great nearly on par with main shooter

No lag taking photos at all took loads earlier without issue. Just a bit of delay in the photos app to process. Same as pixel 3.
I have a Pixel 5 now and I have my old Pixel 3 still here.
What can I say?... The only things I like about the Pixel 5 better are better battery life, more RAM and aluminium body.
The screen is not brighter, it even seems to have a more yellow-ish tint while the Pixel 3 display was just bright white (side to side comparison with full display brightness).
The speakers are awful, especially the one under the glass. It sounds so tinny and has very low volume, I have serious problems hearing the caller when it's getting a bit louder around me. The "stereo speakers" are a joke when watching a video. compared to the down firing speakers the one under glass is barely audible.
The full screen display is not very convenient for daily usage imo. I always tend to "hold" the phone on the chin bezel with my pinky finger and it happens often that it touches the screen and closes the app or changes to a different one.
As good as the P5 feels in the hand, and how good the camera is..... I like my P3 (not xl) more in the end. I even like the P3's bezels more than the full screen of the P5. (and I still didn't get over the punch hole for the camera)

Interesting to hear about your screen brightness. My P5 is quite a bit brighter than my 3XL when both on max brightness. Both are white with no sign of tint. Maybe you have a bad panel?
Speaker under the glass on my P5 is also poor.
I get the bezels points I had gotten used to having the chin and the notch to hold onto!

After some more testing I would say that the P5 doesn't have a slight yellow tint but the P3 (not XL) has a blue tint. I think now the P5 display looks a bit more natural.
Surprisingly both displays look the same in Nightlight Mode.
I just hope there will be an update to fix the speaker's low volume.
The 90Hz display isn't a big deal as I thought. I can use my P3 without even noticing the difference in normal usage (of course I notice it when I look for the differences). I think the P5 would be fine with 60Hz, or they should've gone for 120Hz.
Battery life so far is fantastic. (compared to the P3)

Can't see them changing the speaker volume much to be honest.
On screen refresh I guess everyone is different. My P5 is a lot smooth than my 3XL when scrolling Twitter. If I compare the P5 to my friends S20 on 120hz I can't see a difference. On my PC though I can tell the difference between 120 and 144hz! Maybe the size of the screen makes it less obvious to me?
yes, when using side by side it's absolutely noticable.
I wanted to say that it's not that important to me when it comes to normal daily usage, because I just don't notice it anymore (or I don't give it attention anymore after a while).
I also have a 144Hz display for my computer, and that is a difference you can always tell, without having a 60Hz display side by side with it. But I think the G-Sync (or any sync technology) here is the more important feature.

Absolutely couldn't agree more with everything you said.
If my pixel 3 didnt have a broken camera and charging port I'd keep it.
Battery lasts about twice as long on the PIxel 5 - I miss the "blue'ish" screen and "2-button" mode though.

Question How will the S21 Ultra camera stack up vs iPone 12 Pro Max / Pixel 5?

Last summer I purchased an Xperia 1 II which I really liked for a lot of reasons - the screen, form factor and feel were all great. Unfortunately, the camera was not up to much and really struggled in low light conditions as well as capturing moving objects. As a camera is one of the top priorities for me in a phone, I made the switch and got the Pixel 5. The camera on the Pixel is brilliant and I am happy enough with the phone for now but the small screen and medium-range specs are definitely a shame.
Having seen some brilliant reviews of the S21 Ultra, my interest has been piqued and I am considering pre-ordering. I am also conscious though that reviews often don't really give a thorough, in-depth review of camera capabilities in different everyday situations (often just focusing on headline specs and flashy new features). Having read the S20 Ultra forum, I noticed a lot of negativity around autofocus, images in low light conditions, images of moving subjects and video quality. This goes back a way but having previously had S6 & S7, I thought the cameras were OK but often a little unnatural/beautified.
Does the S21 Ultra appear to be rectifying these issues and will the camera/video quality be on a par with the likes of Pixel 5 & iPhone 12 Pro Max? For the price of the phone, I would really expect it to be very top end.

I know this is very rude of me, but I didn't read, too long of a message lol, and I'm so tired rn. But if you want good camera reviews, you can check DxOMark.
It's my reference for cameras.
Here's the S21 Article
I've read/watched a ton of reviews, many of which offered direct comparisons to the iPhone 12 Pro Max, and a few also included the Pixel 5 (not as many, as it's not considered a top tier phone any more). They all seem to be very capable. If I were to try to average all the reviews and build a consensus, I appears they are very comparable in standard everyday shots. They trade blows here and there, but generally very similar. The iPhone still wins in portrait shots. It also seems to have a slight edge in video. Night shots are tougher to judge, some had the iPhone ahead, some the S21. The S21 was the CLEAR winner in macro and zoom, as well as features. It seemed they generally gave the overall win to the S21, because the categories where the S21 won it did so with greater margins than the iPhone, where it's wins were tighter. And also because the wider range of capabilities made it a more flexible camera. But if the extreme close and extreme far don't fall into your typical usage, the iPhone would probably come out ahead.
It's also probably worth mentioning that Apple is generally pretty polished, and the iPhone 12 has been out for a bit. It's not unusual for Samsung to be a bit rough at release, and take several updates to tweak things. The two phones probably aren't at equal levels of maturity. Being an S20U owner, I can confirm there were definitely some improvements over time. The S20U camera setup was a complete change from the previous generation, while the S21U is more of a refinement on that. So it may not have as much room for improvement as the S20 did. But there's probably a decent chance that it might close some gaps where the iPhone wins, and/or increase some leads where the iPhone loses.
The differencies are minimal. Really. It is like chicken soup vs tomato soup. I did buy S21 Ultra due to the pen. S21U has clearly better camera than P30Pro. But S21U vs i12pro/i13pro vs Pixel 5/6 ... c'mon. If you like to have the best possible photos buy Vivo x70Pro+
I have S21U and wife has Iphone 13PM. Both has pros and cons. From my day to day experience, this is what I found, comparing S21U and the iPhone:
iPhone pros:
- Very fast shutter speed on camera.
- Sharper video overall, especially for night videos.
- camera app very optimized. Everything feels so smooth.
- better camera focus for indoor photos.
iPhone cons:
- white balance is so bad. Every photos turn yellowish, white sometimes turn into blue.
- too much post photo processing, especially true in clouds. Normal cloudy days turn into storm looking clouds.
- over sharpening. Took a photo of wall calendar on the wall, everything else seems bit blurry but the numbers are sharp (not in a good way, like a Photoshop overshaperning).
- portrait photos not as capable as S21U. Hardly take a clear portrait photo of moving kids (1 clear shots out of 6 shots).
- lens flare. Haven't tried night shots yet with the main cam, but the selfie does has this issue.
- no zoom 10x. Once you have this, you will want them on your phone.
- very dimmed videos at night.
- stabilization not as good, very noticeable on 3x lens.
S21U Pros:
- very versatile camera system with 3x, 10x zoom lens.
- white balance most of the time is correct - true to life
- 108 MP shots are a great option to capture extra details
- top notch stabilization on videos and photos even for zoom lens
- portrait photos are better than the iPhone, capture less shaky photos for moving objects with a better blurring object identification.
S21u cons:
- slower shutter speed. Not very usable when taking moving objects indoor
- indoor focus sometimes off, need to click the screen to focus the object.
- camera app not as smooth as iPhone
- color sometimes can be not as true as real life
Those are what I have found so far on my daily basis.
