NoDo issues/comments

So NoDo is here at last....seems way faster and much better than pre-NoDo.
Things I've noticed that I haven't seen publicised -
Headphone button now hangs up a call, didn't used to.
Display driver seems worse for some pages (WPCentral page, Bing search pages - noticeable banding, even where there didn't used to be).
Switch from WiFi to non-WiFi much smoother (I used to have particular problems with this
Anyone noticed anything else or got the same issue with the Display driver that I have?
All in all a big fan but will look forward to any further driver updates that might get the display working to it's Amoled best!

- mine not saving camera setting such as wide dynamic range or antishake, also video resolution is not saved
But this were also in old soft

no problems here. everything seems to be improved

That's a feature. Microsoft is considering allowing the settings to be saved.

Am I alone with the display banding (really noticeable if you press the search button - the Bing 'Wallpaper' used to be really high resolution but now looks pants)?

Considering? They better allow it because it's the most frustrating part of WP7 for me. I want it in 720 as soon as I go into video mode!

That was like that before NoDo. I think it just depends on the wallpaper tbh. Dont think the quality is lower. But just not the right rendering.
Ive wrote to MS on facebook. On their feedback programme and questionaires and twitter about the camera settings.
Accordingly by alot of websites its a "feature" so incase you mess up settings it goes back to normal. I can justify this for all the settings except the quality settings. Damn why would you want to shoot in lower resolution when you can do it in 720p?

Isnt that OEM's fault for not getting the code right?
I wish MS just stopped mucking around and release their own damn phone. That way there will be no fall in quality as they will be able to control everything on the phone and do it, the way its meant to be done

I have noticed the same problem with display.
The most visible artefacts I have found in "Now" app. Waves the the top of the screen are corrupted with soime artefacts.
I have also noticed that photos in people tile are more bright than before update.

Again your just being picky. Ive seen the wave ripples for vibration before the update.
It shouldnt affect the display or anything else. Its just an OS update and not a firmware update (well atleast that was the case for me)
Ive said this alot of times before that the clarity of AMOLED screens isnt as good as LCD screens. Yeah colours might be nicer but its not as clear as LCD SLCD

I do not want to compare SuperAmoled (Oled) and SLCD (LCD).
I do compare a display issue which appeared after update to 7008/NoDo from 7004.
There was no display issue with firmware 7004. Al least I believe it because I had not noticed it before update.

I'm just saying that it was there already. And its amoled issue and not the OS as their two different things

Is there absolutely no improvement to the 720P capture? Is it still very choppy?
I wish Samsung would sort out the abnormally high shutter speed/white balance bug, so that the videos would appear less choppy.

Live mail folders still dosent update correct on my phone.

Is there a way to lower the screen resolution from 1080p to 720p?

I hear they lower the res from 1440 to 1080 in the G3 so is there a way to lower the screen resolution in the G2 from 1080p to 720p?
I couldn't find anything about it in search.

Screen resolution of an lCD is a physical attribute, it cannot be changed. You can change the software to renderer the image so you would get a lower resolution data to show, and since android source is available, it is technically possible. I doubt anybody tried, because our device has a adequite computing power to generate 1080p images. On the other hand, lg g3 has almost same power, but it displays almost double size image. For g2, it won't worth the lost of quality.
The issue is, since LCD will display it on its physical resolution(there is no other way), your image quality will be far worse than the down sampled version. For example, if you render the sceen at 720p, and show it on a 720p 5.2" display, you will lose ~%55 of your data, but since you render your source on this resolution, will be sharp, just won't have so much detail. If you display this 720p image in 1080p display however, screen resolution cannot be changed, so your screen will try to calculate the missing %55, and then show you the result. Since there is no original data, it assumes the missing pixels were like the ones around them, which means your result will be blurry.
As a side note, old tube displays does not have a resolution, they can support various resolutions. We used to set resolution to our taste between speed and detail back then.

enigmanp covered the technical aspect of it and I'll just follow up with my own personal experience.
I had a chinese android tablet running at 2048x1536 resolution, the same resolution commonly found in iPad tablets.
My Android tablet sometimes perform sluggish because of the high resolution. Even though the CPU was a quad core 1Ghz, it's still chinese and the GPU wasn't great either. So I lowered the resolution and everything was blurred and not sharp at all (due to the reasons enigmamp explained above). I DID notice an improvement in overall speed, but apps started misbehaving and it was all a huge mess.
Now the only reason I did that was because I found my tablet lacking smoothness/performance. I just don't quite see why you'd want to do that on the G2 since the CPU and GPU can clearly handle even the most intensive 3D games on high detail. Could you please explain?

So why it doesn't get blurry on the G3 then?

If it's to save battery, I doubt you'll see much of a change.
The GPU is working on a smaller load but most of the time it's running at 200 MHz anyway. But I'm no expert, I'm just telling what I know and what I've experienced. I'll head over to the g3 thread to read more!

Reducing the number of pixels would help you to save battery if you are using a phone with AMOLED screen, sadly it is not the case with LG G2. So even by turning the resolution down, you are using pretty much the same amount of battery as you would with full 1080p resolution.
If you want to go ahead with it anyway, there are plenty of apps on the play store which does this. Just search "resolution" in the play store and you'll find them. However I don't think this will help your battery life at all, nor do I recommend it.

Late addition
Well, when i found out this was an option i just had to tinker. I have a G2 that is my daily driver and a S6 for back up. I changed it to 900x1600 480dpi and it works just fine. The camera touch focus is a little off, but otherwise it is sooper smooth now. I also throttle the CPU down. So both together I get a good experience and decent battery life. I know this is a late response, but to anyone out there with root and some lackluster performance might want to give this a shot. I needed to reboot once to correct some keyboard skewing. I also adjusted the height of the keyboard to compensate for the change in real estate. Works like a champ, no real noticeable degradation in viewing pics or videos. I'm going to try this on my Nook Hd+. It needs a shot in the arm (no pun intended).

download terminal
write in terminal :
su [ENTER]
wm size 720x1280 && wm density 220 [ENTER]
new density: new resolution * current dpi / old resolution ( for e.g. 720*1280*480/(1080*1920) = 213), altough i tested, and it seems that 240 is the best (for me), but it looks awful, for me, so i will go back to full hd + 410 dpi
ofc root required )
anyway, please share with us if it will be any battery life improvement

[Poll] Wqhd or Fhd?

What are you using?
Did you feel much difference?

FHD for power saving under 15%. WQHD for everything else.
With a live wallpaper like "Solar System Your World" from Google Pixel, if it's FHD you can see the pixels moving.

There's absolutely no reason at all to run anything other than WQHD. Power saving are negligible.

Hello,
How did you manage to install that lwp on your phone? I found a thread on xda and I install the apk but I can not find the wallpaper later to turn it on...

Android 7.0 required. Install like any other app alongside Google Wallpapers from Playstore.

I use the Gear VR, therefore use wqhd.

I use WQHD simply because why have an AMOLED WQHD screen if you won't use it?
Also, what with the usefulness of fast charging, I've found the power changes to be negligible.

tried both, WQHD preferred, especially when you look at the icons and all other stuff on the phone

Yesterday my phone went into a constant reboot loop. I let it go until the battery died because I couldn't do anything else. When I charged it back up it went to a previous backup and lost all my customizations.
Now I cannot put it into wqhd. If I try it just crashes the settings app any advice?

I switch between the two and I've noticed something, I can't tell the difference lol they both look the same to me lol 2nd the battery ? dies a bit quicker running WQHD

The only real difference in battery life between the two is if you spend the majority of your phone usage time playings graphics intensive games. Without games the battery savings from FHD are negligible/nonexistent

For me , both the same . i've been tested and same battery and results .

well this thread is getting more exciting.. let's compare the battery life results between QHD and FHD .. or even with HD

Anyway to decrease screen resolution in marshmallow safely?

WQHD ofc as if you don't game the power saving is not worth to have blurry image. It's just too little of a difference + the phone feels faster/more fluid on wqhd. FHD is if you game more to have better framerate and battery life as the GPU will have a lot less stress. For general use either resolution is of a no problem for that GPU. Cheers!

So why does the power saving profiles want to decrease screen resolution? I'm currently testing, though. I really don't see any big difference in terms of quality between WQHD and FHD.

you will be able to tell more if your wallpaper is a picture you have taken with your camera and not just a bad quality one from Google etc
Wqhd is a lot better
Go to change your power saving mode and customise it
It will tell you even if you go down from qhd to just hd it will only save you 4 minutes of battery

Impact on battery life - FHD+ v.s QHD+

Hello,
I searched around this forum and didn't find anyone talking about this topic yet, so thought I would start one. Has anyone done any tests or observed the difference in battery usage between FHD+ v.s QHD+ screen resolution on their S8/S8+? Also, can anyone actually tell the difference between the two different resolutions?
Thanks

I can tell a very slight difference in resolution, my fiance has the same phone, so I set them to the two different resolutions and pulled up the same webpage. Next to each other the text is crisper, but not worth the hour and a half SoT that I lose for it.

I can see a clear difference when reading a pdf version of a tabloid size newspaper. Fonts are too fuzzy when using FHD but on QHD they look sharp.

On FHD+ I often notice the icons are fuzzy, they have blurred edges, et cetera. Did not notice any battery impact so far though.

If you want to see clear difference, use it with VR glasses, here even QHD is not enough, you can still clearly see individual pixels even in QHD and forget about FHD, the pixelation is actually distracting. As far as battery goes, I think it depends on a usage: If you play graphic intensive game I can see how rendering extra pixels can affect battery, but often this may be offset by higher frame rate. In more static displays I don't see how this should be making much of the difference, I think all pixels light up regardless of the resolution and it just takes more GPU power to process more pixels, but I could be wrong.

I noticed fuzzy icons on my s8 also however I am using a custom icon set and nova launcher. I was able to fix the fuzzyness by re-selecting/resetting the icons for each shortcut on my launcher. Now regardless of the resolution chosen the icons stay sharp. Maybe the same will work for you if you're also using custom icons that is.

For some reason, even though I'm the highest level tinkerer when it comes to that, I prefer to stick to the stock launcher and icons with the S8. So it was with stock icons.

I know this is the S8 forums, but I've been testing this for the past week or so on my S8+, and I consistently get an extra 1-1.5 hours of SoT when its set at FHD+ vs QHD+. I personally can't tell a difference between the two 99% of the time. Everything is still pretty sharp for me on Nova and a custom icon set (Vopor).
Still not sure which resolution to settle with. It's nice having the extra SoT, but I also feel like I should be making the most out of the gorgeous screen; even if I can't tell a difference most of the time lol... I get about 4-4.5hrs total SoT on QHD+, as opposed to 5-5.5hrs SoT at FHD+.

I have the Canadian Snapdragon version. I set it to FHD+ once and got about 1-1.5 hours more SOT. The text is noticeably more fuzzy, like it's always out of focus. I already get 6 hours SOT with WQHD+ so I just stuck with that.

You actually hit it pretty close. All pixels on the screen are used regardless. Just a bigger sample size with FHD. However, QHD will use a little more battery if you are changing the image on the display. For the fact that it has to draw that many more pixels each time the image changes. Which is millions of pixels. But I believe a lot of static image changing is done by the cpu and not the gpu. where gpu is used mainly for constant motion on screen.
But honestly part of the reason they have such high resolution is for VR. That and to make more sense of taking UHD pics and videos. Most people won't notice a working difference between the two through regular use unless they keep it really close to their face, or have very good eye sight.
So you will see it use some extra battery. Not a detrimental amount more unless you are a heavy user of games and whatnot. Or if you force GPU rendering, then you should see a big difference in battery

Hmm... yes, that is the dilemma for me as well. I could tell that FHD looks slightly more fuzzy compared to QHD. Facebook and Whatsapp apps showed more washed out texts when comparing the two, for example. Would be nice to get more feedback from the others

I am using QHD+ on the S8+, as it is a little larger than the S8. As a techie, using a display at non native resolution is unbearable Kidding, with pentile, you can not tell anyway. I am having good to great battery life and I like small fonts - so I do definetly see a difference and therefore amusing the higher resolution.

I set mine to HD. That's not an option in the poll though.

I enjoy the extra battery life so FHD+ ftw. And on the occasion when I do consume 2160p content on YouTube I simply drag down the quick settings/notification pane and change the phone from Optimized to Entertainment. No big deal.

Or someone with old eyes that can't tell the difference...

Whenever I go into phone maintenance and enable the battery saver thing it tells me I only save like 15mins by switching from WQHD+ down to FHD+ so that's doesn't seem worth it at all. Anybody else seeing the same... It actually tells me most of my battery savings (around a hour) would come from disabling the AOD.

Hmm all this time I've been thinking the difference between fullhd+ and qhd+ would be significant, guess il be changing it to the latter then.

Not even thinking about that lol just i can see the screen and its bright and great i dont care else

FHD+ is my way to go.
I've had it on QHD+ for the last 2 weeks but I never really found any difference and the "fuzzy" things got fixed when I changed the DPI so I have no problema at all. Even if FHD+ provides 30 minutes more of battery life I take it.

1080p Display???

Hey guys, so I'm sold on the OnePlus 5 in every way but there's one glaring con that has me on the fence here. My current phone is a Nexus 6, and I LOVE the size and QHD display! Now, I realize that they don't really make 6" phones much anymore....... but the thing that really has me unsure us the 1080p display in the 5. It's an upgrade for me in every way, but a downgrade in screen resolution. My question here, is there a HUGE noticeable difference in the 1080p panel when compared to a QHD one?

When I had the 3T the display was amazing. I'm my opinion 1080p for a device is solid. Doesn't drain battery like the s8.

I had a (casual) look at the OnePlus 5 yesterday and didn't notice the "missing" pixels when compared to my Nexus 6P. There is a good chance the OnePlus 5 will be next phone very soon.

Apparently the 5's screen has improved some what on the 3T despite being essentially the same panel?
I too am disappointed at the lack of a QHD screen but I guess it's a trade off between battery drain and price.

Yeah I'm trying to think hard on this one, it's smaller, has a lower res screen, and doesn't have stereo front facing speakers like my Nexus 6. Everything else about it runs circles around this device though. Decisions decisions.....
Sent from my Nexus 6 using Tapatalk

Having gone from Nexus 6 to OP3 and soon to OP5, I don't see the lower resolution as an issue. If comparing the screens of OP3 and N6 side by side, I'm having really hard time seeing any real difference. If I put the phone right next to my face, then yes I can see the pixels on the OP3. In normal use, there is no visible difference to me at all. So if you want to see the difference, then by pixel peeping you can see it. In real world use, for me at least the lower PPI makes no difference at all. The lack of stereo speakers when going from N6 to OP5 is a sort of bummer, but the performance and better battery life will easily make up for it.

i went from a n6p tp a op3t and didnt notice any problems with the screen, no different from normal use at all. i never regretted the decision to move...
The stereo speakers i do miss, but it is what it is

Went from a Nexus 6P and Note 4 to the OP5 and the display it just fine in terms of size and quality. I like it very much, great color balance, sharp and saturated enough for my liking.

Yes, the 1080 resolution is a major draw back for me. Because it's a pentile display the effective resolution is only around 800-900. It's not good enough.

Used my OnePlus 5 for a day, no issues with the 1080p display compared to my LG G3. Was expecting a decent downgrade, but honestly don't notice it at all and can't tell the difference.

Unless you frequently use VR, you will not notice the difference without looking closely. The display is the same one as the 3T because it's a very good panel.

S8+ in FHD mode still has QHD display matrix. So, this test shows how well Samsung "emulated" FHD display using QHD one and what is the gain from such operation. QHD display has to drive all it's pixels even if GPU would calculate resolution for FHD one. So, this test can be applied for S8+ FHD/QHD modes...
Regarding display resolutions, I am kinda agree with Apple "retina" reasons - as long at it more then 300 dpi it should be fine for looking at normal distance.

That's not true. In FHD mode on the S8 every other Pixel is completely turned off(the advantage of an OLED display where this can be done) so it is true 1080. You are getting all the battery savings a true 1080 display is getting.

Simple math:
Every other pixel of 1440 will give you 720 pixels.
Every 1 of 3 will yield 960 pixels - still not 1080.
Do you know how Samsung actually downscale 1440 into 1080?
If it will shutdown pixels, then brightness needs to be compensated by increasing current through remaining pixels... I don't have this information, do you?
PS: after looking on some examples (closeups of screen shots of S7 HD, FHD and QHD modes) I think that Samsung just uses zooming function to scale display resolutions and does not shutdown pixels. And if this is the case, my previous post still stands - all gain Samsung demonstrated by lowering resolution is just from GPU rendering lesser pixels.

Simple math:
Every other pixel of 1440 will give you 720 pixels.
Every 1 of 3 will yield 960 pixels - still not 1080.
Do you know how Samsung actually downscale 1440 into 1080?

Batfink is correct, it works by actually switching off pixels on the display. There's even an app on the Playstore that'll do the same thing if you have a rooted phone.

Any references to prove this statement? or arguments?
PS: sometimes ago, I had asked author of Battery Calibration app (distributed through Play Store and sure needed root) where did he get an idea that by deleting certain file in Android OS he will force battery re-calibration process... His reply was - on XDA forum in thread which was using reference to his application as remedy for battery calibration issue. See where I am going - one myth got dragged from place to place and later on many use it as a source of true knowledge without even testing/questioning it.

This article shows how the performance is affected by the resolution change....

I'm not saying the battery doesn't or does drain more, only that the resolution is actually changed because it is. It's really quite simple with an AMOLED screen to turn a certain amount of pixels off and it's a native Android thing to be able to do it.
It's the same as Android TV boxes being able to output at say 720or 1080.

This is a fact that resolution will affect performance (FPS). GPU has to render much less pixels in FHD vs QHD.
I am arguing how FHD got scaled to QHD matrix. Let's make an experiment, set resolution to even lowest setting like 720 - and if Samsung shuts down every other pixel then you should see black dots on white background. (because only half of QHD pixels should be lit according to your argument). And remaining pixels should double current consumption to keep up with overall screen brightness... is it what we seeing?
Maybe it's just like with PC monitor. Video card just scales lower resolution into HD monitor with high pixel count. So, I have 4k monitor but when I scale 800x640 resolution into it I see native pixels got combined into HUGE one and there is no black voids in between native white/lit pixels. Though every pixel on display can be controlled independently...

Yes, the 1080 resolution is a major draw back for me. Because it's a pentile display the effective resolution is only around 800-900. It's not good enough.

A QHD display drains very little more battery than a 1080 display...

Either ways they don't have that kind of technology yet. probably the 5T will have it. Lets nag the oneplus for QHD in the forums until they give it to us... Didn't they say that they listen to their community.
