Does the Presidio Grip rise above the camera bump? Thanks.

---------- Post added at 07:01 AM ---------- Previous post was at 06:46 AM ----------

A negative with the Ultra's main camera setup is that it uses phase detect AF (PDAF), as compared to the S20+'s Dual Pixel AF (DPAF).

DPAF:

https://www.gsmarena.com/samsungs_d...e_canons_dual_pixel_auto_focus-news-16805.php

Source of Ultra's use of PDAF:

https://www.dpreview.com/news/19883...tphones-with-up-to-108mp-capture-and-8k-video

"S20 Ultra takes the entire setup to a whole other level; it offers a 108-megapixel F1.8 main camera with a whopping 1/1.33" sensor, the second largest sensor size we've ever seen in a phone (right behind the 1/1.2" sensor in the well-respected Nokia 808 41MP camera). This sensor foregoes the speedy dual pixel AF of the main cameras on the lower end modules, opting for only the lower-performing sparse phase-detect AF".
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] VZTech:
Well that could be a real issue. Maybe Samsung can't fix the auto focus due to using pdaf? That would suck.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sabesh:
Samsung has said that they'd fix it with a software update. However, I doubt that they can actually "fix" it, as PDAF is what it is. Maybe they can improve it, that's about it. This review has an example of PDAF issues:

https://youtu.be/SRkK6lKu3cw

Anyways, I've dealt with PDAF systems before, and know some work arounds. For most people who just point and shoot, PDAF will be frustrating at times.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] VZTech:
Well, thats what ALOT of us do. This could be a serious dealbreaker. Losing shots because of autofocus would be a joke on this phone. I was going to keep my phone after debating just cancelling the order, but i'm thinking of possibly just sending it back when it arrives. We really don't know if samsung can fix it with SW.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sabesh:
Well, were you able to take good shots with Galaxy phones prior to S7? Or, have you recently used any phones other than Samsung? If you got good pictures with either of these 2 scenarios, then you are good with PDAF.

AFAIK, only Samsung phones and Canon cameras use DPAF.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Jairus24:
Samsung already fixed the accuracy of the auto focus especially in low light, update is already out in Korean variant: https://youtu.be/TRYwiiGnrVw

As for focus speed, it will never be as fast as dual pixel AF; it must be really hard to put two photo diodes in that small 0.8 micron pixel size and different bayer arrangement to make DPAF work. I read that Sony has a solution though, they will use 2x2 On-Chip Lens Solution in their next quad bayer sensors.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sabesh:
Excellent! Yes, PDAF speed will always be slower than DPAF, at least with my experience shooting with my Sony A7R III (PDAF) and Canon EOS M6 (DPAF). For me, for phone usage, accuracy is more important than speed, as I won't be shooting sports, moving kids etc with it.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] VZTech:
Well hopefully they can make it quick enough. I guess time will tell.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Paul_Deemer:
You really do sound like your not at all enthusiastic about your purchase. It also sounds like the cameras are your main selling point. So make easy on yourself and cancel your order Today. ;)
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cpufrost:
Not so fast there!

I tend to be pessimistic about things rather than build them up as I'd much rather feel excited than disappointed. It's not really about the cost. I'm sure if I really did experience remorse and didn't want to deal with either fees or hassle of return I could sell it especially considering the *possible* shortage in the coming weeks/months.

There's always hope. I'm counting on the fact that pro mode is available in video. And 8K capture actually is useful for getting good STILL images. "Spray and pray" is a fact of life in action photography and simply a dream on a phone. Until now. The 100X zoom is so much easier than reaching for my spotting scope in the morning to see what lies in the pasture as I always have my phone in hand after getting up. Then there's 5G.

I checked with VZW and my plan would work with their 5G when I happen to be in an area with coverage which is probably 1% (and I'm being generous!) of the time. Not that their LTE is lacking, I've seen nearly 300Mbps down in Annapolis MD which blows TMO's "fake 5G" out of the water. I have both TMO and VZW and it would be funny if I had both variants of 5G at the same time, assuming I don't have to switch out SIM cards but I'm not holding my breath on the US Unlocked version supporting esim and physical sim at the same time like my XS Max and 11Pro Max currently do.

I buy a lot of phones as you probably figured out by now. This is no different. I don't plan on canceling, it only crossed my mind out of frustration and retaliation based on the Samsung store's ridiculous non existing notification system that my preorder was cancelled. So instead of getting the phone in hand 40 hours from now it's more like 350. A paper cut stings but when you dip it in brine it hurts a hell of a lot more. ;)

But mainly the fact is I never favor something over another without actually owning and using the device so I really need to have it. Will it be a POS? Highly unlikely. I've owned every Samsung phone since the Galaxy S and TBH the only one I truly hated was the S2 Skyrocket because I needed to find a battery charger by lunchtime or I didn't have a phone. Yeah, it was that bad.

Bringing back unlocked bootloaders would probably be as wishful thinking as bringing back Elvis or 8 track tapes (OK that's pushing it but you get the idea!) but it would be awesome if that would happen.

I still have my Exynos S9+ 256GB Duos sitting in a drawer. Its still usable so perhaps I should custom rom that one and be done with it.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Davey Dual Sim:
No, and the reviews I'm seeing are saying the cAmera is a major step forward, but needs a software update, which I'm not that fussed about
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sunmybun:
there is no such thing as fake 5g except for att's "5G-E"

tmobiles 5g is based on lower frequencies but with much less spectrum. but they also have mmwave holdings

whereas verizon have huge number of mmwave from the auction.

5g has to do with the new implementations and NR

so stop bashing other services.

i did have the galaxy s2 also. i did buy couple batteries to so i can cycle them evenly without losing capacity as much as just using one battery.

s2 wasnt great in battery amount but wasnt many smartphones at that time also?

technology has changed alot.

for someone who owned alot of phones should know that phones are not always perfect.

i also think many people who have problems with samsung store are not entirely true about their preorder time. people do cancel their orders and change so it may effect the stock available.

i know for sure that when i preorder through samsung, it went as planned most of the time. maybe im just lucky most of the time
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cpufrost:
I call it fake 5G simply because it has no real perceivable benefit over LTE. But it's Tmobile and they are quite horrible service wise in my area so why am I not surprised in the least.

Maybe peasant 5G would be a better term as truly fake 5G, as you mentioned, is AT&T's so called 5GE.

And TBH, again IMHO, 5G is a SHAM simply because it would be better to have LTE coverage EVERYWHERE when it's truly not. They are spending BILLIONS on this when they could just build out LTE with more backhaul bandwidth. The only good thing with mmwave is perhaps the highest density environments such as stadiums and perhaps convention centers.

To get multi gig coverage everywhere is going to require radio hardware (antennas) literally on every single power, light, and flagpole everywhere. I live in a rural area so it wouldn't even reach my home outdoors.

But if they want to run the backhauls in the utility right of ways here, I'll give up some land for some poles and an uncapped 10Gbps handout with a block of static IPs. ;)

Everyone is complaining about the price of the phones. Remember the S10 5G and how expensive it was? Well when you have 5G hardware (whether you need/want it or not!), you have to pay for it.

Imagine what an iPhone 12 Pro Max (or whatever they call it) with 5G capability is going to cost! Especially with 512GB or more storage.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] _Dennis_:
5G is about more than speed. Lower latency and better use of available spectrum come immediately to mind.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cpufrost:
Yes you are correct.

But what people want is what matters most. Speed.

Even though it doesn't really feel that much faster. Or does it?

Wifi6 gets 750up and down at work and it doesn't seem all different than LTE.

Of course if you download multi gig files, movies, et al Of course it makes a huge difference!

I tend to favor symmetrical speeds and current 5G cannot deliver that. So that 15GB 8K video file is going to take forever to get to my dropbox. Still. ;)
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] _Dennis_:
Current 5G uses 4G as upload (on Verizon, not sure about the rest).
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cpufrost:
Right, that's my point, upload is unchanged and that matters most when driving home from a gig with 100+ GB of footage. The phone is smoking hot too!
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] _Dennis_:
Yes, but when I'm trying to download 10 hours of movies before a flight, downloads speeds are more important.

Usage determines what speeds are most important.

I would argue that while speed is the widest known advancement from 5G, the other advancements are more important in the long run. Lower latency is absolutely needed for the Self-driving connected cars that are the future. Better use of spectrum means more throughput for everyone.

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] 3Shirts:
My most trusted tech review site is TechRadar. They have a review but are holding off on calling it final and giving a score because Samsung have told them that early review models have some issues which will be fixed before launch. They've given a deadline of 6th March since people want reviews in order to decide whether to buy.

That seems a fair approach; Don't write off the pre-release firmware but, equally, don't review based on some hypothetical 'fixed' version which many never happen.

I have a S20U with the March 1 update. I regret it due to the camera issues (which I don't think Samsung can mitigate much without A LOT of work).

Hopefully the mysterious Note 20 uses a similar camera array & Samsung is forced to work on the software very hard to prevent another bomb.

What are the work arounds?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sabesh:
Sorry, not work around per we, but technique. For moving objects, PDAF tends to pick the closest point while tracking. It's better to adjust the AF point manually. Same with low light situations. Once you start doing this, you'll get the hang of where to put the AF point in different situations.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] _Dennis_:
His review was 95% good things to say, only bad things were price, 8k and 100x being not particularly useful (though they help make 30x and 4k better), and autofocus.

I find it amazing people pick the few things that could be better (especially the 8k/100x stuff, but to a lesser extent the autofocus) to be mad about even though they have few practical effects. Autofocus is nice, but tap to focus is better (you as the photographer get to choose focus).
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Djapatos:
Waiiit..are they saying tap to focus works fine? I m good then if thats the case. I have an old habit of always tap to focus lol
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] waqas.sonic:
I was comparing it with his S10 review, which changed the game at that time. I understand the positives but I really wanted this to blow over the competition, but it is what it is, still getting mine.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Illrigger:
Bear in mind that the Ultra is not really a successor to the S10 - the S20 is the successor to the S10, and the S20+ is the successor to the S10+ - the early idea that the S20 is the successor to the S10e just isn't accurate when you compare the three. Both of those still use DPAF and should be just as fast and good at AF as their predecessors.

The S20 Ultra is a whole new beast, with a whole different audience - it's a high end device for people who use the phone in a more professional or enthusiast role, rather than just pulling the phone out and snapping a selfie or quick shot of friends. The Pro Mode options make that pretty clear, with ISO settings from 50 to 3200, shutter speeds from 1/12000 to 30 seconds, and granular manual focus and white balance settings. You don't expect to whip out a DLSR and immediately get a pic as fast as you do an iPhone, and you don't pull out an iPhone expecting to be able to tweak the shot like you can a DSLR. The Ultra is kinda between the two ends of that comparison.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Zirox:
I have no idea what reviews you have seen sounds to me like this is just a trash talk post.and all the so call reviewer are pretty much dumb and hungry for money because it's not final software Samsung said a fix for the autofocus is on the works.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] _Dennis_:
The thing is, with the S10 and S10+ the refrain was "nothing major changed" seems like with flagships, there will always be a problem. The S20U send to get great reviews, except it's "not worth the price" and the "autofocus isn't fast" with a smattering of "I don't understand shallow depth of field" on a few reviews. I'll play with the phone, and return it it I don't see the difference between it and my note 10.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] 3Shirts:
That's kinda ridiculous. No-one uses a phone, any phone, for professional photography! Suggesting it's closer to a DSLR than an iPhone is ridiculous and if it sits in between then it's really the worst of both worlds, surely? Too slow for quick auto shots, and not good enough for fiddly 'pro mode' shots. If that actually is the aim of this phone, they have made a huge mistake.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Illrigger:
That's a false flag. People don't use phones for pro photography because phones aren't good enough for professional photography, not the other way around. You think pros LIKE carrying around 20 pounds of camera gear everywhere they go?

Samsung shot their entire launch event on S20 Ultras, so they certainly are confident in that use case and are aiming the product that way.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] waqas.sonic:
I understand where you are coming from, but I would bet that 9/10 pro photoshoots will not be shot using S20 Ultra. Sure it sits b/w the two but a phone, generally needs to be good at point and shoot, that's one of the major USPs of carrying a really good phone camera (at least for me).
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] 3Shirts:
Yes but phones will never be as good because dedicated pro cameras will always be improving too. Sure the S20 Ultra is better than a 10 year old DSLR (maybe) , it's not better than a 2020 model. And next years phone won't be as good as next years DSLRs. The gap isn't going to close because a convergent device can't possibly outperform a dedicated one.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shollywood:
Huh? If you release something and tout them as "features" or "game changers" over competitors, then they should work. Obviously those features are going to be reviewed. Why would anyone review or read a review of a feature , chipset, etc. that has been reviewed many times already because it exists in several devices?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Illrigger:
It will be more like 1 in a million photo shoots, as a phone with a "prosumer" camera array is an emerging market waiting for customers to find the best use case.

If that really is what you care about, you should get an S20+, not an Ultra. That's what my original post is all about.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] _Dennis_:
Clearly I meant the reviewer should just throw the phone on the ground, call it a smashing hit and move on.....

Or you could, you know, review the phone. Anyone who is shooting 8K or 100X is doing so for a very specific reason, and should understand the limitations. The fact is, 100x and 8K provide headroom, so the 30X and 4K look better than competitors. Do you see many car reviews complaining that a car is throttled at 100mph even though the speedometer goes to 120mph? No, because the reason you have a bit more on the speedometer is to keep the "normal" range of speed in a easily seen part of the speedometer.

The SD865 hasn't been reviewed before, this is the first phone released with it.

The 120hz screen hasn't been reviewed, and only what, 1 or 2 other 120hz screens have been released?

5G on all bands hasn't been released before, granted that is much harder to test because carrier limits.

Was expecting that I'd likely return my Ultra based on this kind of chat.(Every phone release has this kind of chat)..... but there is no way in hell that's happening.

My LTE and 4G are noticably better on T-Mobile here in downtown Chicago than my 10+.

Loved the Note camera. Love this way more...but for the life of me every 'regular'' photo is better than 100mp. Loving zoom to 40.

The HZ choice is REALLY disappointing here. Ridiculous. Counting on that fixed.

Biggest power user on earth, but the battery was at 10% at 6pm with heavy use since 6am. 60mhz. Lot of work stuff.

[Huawei P30 Pro Questions & Answers] ypocat:
Hi Guys,

in EMUI 9 it was possible to change zoom level by dragging/sliding your finger over any side of the camera screen -- i.e. not limited to the side which is showing the actual zoom control.

After flashing to EMUI 10, I can only zoom by dragging/sliding over the actual zoom control.

This is terrible because in the landscape mode, the zoom control is always displayed horizontally - and thus not reachable by with the same hand which is holding the phone (single-handed camera operation).

For me this basically kills the usability of this phone (and the upcoming P40) to the point when I'm not using it anymore as my primary. (There's always something else in my other hand, e.g. dog leashes.)

On S10+ the Camera is perfectly usable in landscape in single-handed mode (right hand).

Anyone else experiencing this? Any remedies?
