DPI change? - Droid Ultra Q&A, Help & Troubleshooting

Has anyone used a program for the droid ultra?
Sent from my XT1080 using Tapatalk

I used Xposed with App Settings Module. I didn't change the dpi setting, I changed the Screen (dp) setting to 320x480 which gave me 5 columns in the app drawer. I don't know what you are going for, but it works great for me.
edit: As it turns out, you will also need to set dpi to 300 to get the 5 columns on moto launcher.

I set my dpi to 280 in the build.prop (stock is 320) and used app settings to change the dpi back to 320 for the camera and active display and it worked great. However, I don't know what it is, psychological maybe, but my eyes strained immediately after setting it at 280 dpi and I've done this 2 times and both times I ended up setting it right back at 320. The Moto X is also set at 320 dpi and I felt the Maxx was not taking advantage of the bigger screen since everything is just enlarged compared to the Moto X and the only real estate gained is from the nav buttons being capacitive on the Maxx. I would like to compare the Maxx to other 5" screens to see how they take advantage of the bigger size (maybe the fact the Maxx is 720p might present a disadvantage compared to the competitors). At this point, the only advantage to the Moto X is the bigger battery but overall, the X is much better as a daily driver, especially if you like the one hand experience which is extremely comfortable/ natural with the X because of the small size and light weight. The 2013 Moto X is growing on me more and more, might have to switch out with the wife pretty soon. LOL

htc sensaation resolution

i just checked my htc sensation roted resouktation and it shows that my screen 240ppi rather then what it states on htc phone
Display Type S-LCD capacitive touchscreen, 16M colors
Size 540 x 960 pixels, 4.3 inches (~256 ppi pixel density)
source from http://www.gsmarena.com/htc_sensation-3875.php
and a screen shot of showing that it is running 540*960 at 240 ppi rather then 256
i need to know if this is only happening to me or your phone have the same ppi
please reply to me anyone
beside i just wanna know i'm not really worried about the ppi thing but i want to know if this is only happening to me or other people have the same thing.
i'm using lcd resolution app from market its free and only require root.
my phone is set at the same 240 ppi

i wonder why they had to lie about the ppi thing.
HTC have not listed the dpi on this phone as 256.... GSM arena can say what ever spec they want but it doesnt mean it true. The optimum dpi for that display when its sold may be 256 or may not but either way all HTC roms are set as 240..
all that prog does is change the entry in the build prop file

in the software you can actually change the resolution but i thought lets just stick with 240 thing.
The software is telling you dpi, not ppi. A dot can consists of more than 1 pixel, and if you set the dpi so that each pixel contains more than 1 dot... it can look weird.
Changing the dpi setting can increase/decrease the font and various graphics on screen. That's why many of the 5- or 7-inch tablets, although only have WVGA resolution, display more stuff on screen than many of the WVGA phones. They simply scale up the dpi setting. Of course setting it too high on a low ppi screen will make everything looks crappy.

Skyrocket DPI

What do you think is the reason that Samsung puts such a beautiful high res screen in the SGSII (Skyrocket of course) then sets the DPI to 240?
Coming from my Atrix, everything looks HUGE and not just because the screen is bigger.
I have installed a utility that I can use to change the DPI to 180, which I like much better. Some apps don't like it, like the phone app doesn't size appropriately etc.
I'm just curious as to why they limit screen real estate like that?
I actually like the big icons. Easier to see looks lezs cluterd. Mabye the thougt most people would prefer it that way. Bigger is better. I wish we had a 5.5 inch display
if the icons were any smaller they would look blurry and underscaled on the SR, cause your Atrix i believe had a qHD 960x540 screen and the SR has a 800x480 which has a lower dpi and keep in mind the icon PNGs are 72x72 and they are displayed as 72 pixels wide on both of the devices, and the Atrix is 60 pixels wider and 160 pixels taller so icons are going to appear smaller than they do on the SR cause of the extra screen real estate

[Q] Pixel Density SkyRocket and Infuse are different

Hi,
I have a Samsung SkyRocket and Infuse both are set at a HDPI of 240.The Infuse has a DPI (dot per inch) width of 234.46153
and DPI height of 236,27907. The SkyRocket has a DPI width of 160.42105 and DPI height of 160.0.
Since both phones are set at a HDPI of 240 I am assuming that the Infuse has a better screen than the Skyrocket? I thought they were suppose to be the same screen? Why are the dot density different?
Looking at both phones, the Infuse has much sharper and illuminated fonts.
Thank you for any useful information in advance,
Giovanni
DPI is length (in X or Y direction) / amount of dots (pixels - for ppi).
If both screens have the same size and same proportion (which means equal X and Y sizes) - it means both screens have the same actual DPI.
That is, unless one of the screens is Pentile and the other isn't - which is not the case here.
You can see in specs that both screens are approx. 207ppi (pixels per inch). This is physical measurement, HW.
Whatever is set in SW - can be changed.
Hi Jack,
Thank you for your response. What you say makes a lot of sense.
Would you happen to know? Why is it that Pixel Density (dots per inch) is much lower on the SkyRocket after a factory reset? The app that I'm using is Screen&System and is showing a DPI width of 160.42105 and DPI height of 160.0. for the SkyRocket. Is there anyway
to change that and make it the same as the Infuse's width of 234.46153 and DPI height of 236,27907? Both phone's
are set at a HDPI of 240 already.
Thank you for your help!

Since the app can't physically measure a screen, you'll need to know where the measurement comes from to see why it's shown as it is. Maybe it's another setting in build.prop, maybe something else.
Thank you for your response. Would you happen to know? Is there an app out there where I can verify where the measurement is coming from? I think I may have a defective screen with my Samsung SkyRocket
Thank you as your responses are much appreciated.

[Q] Can the resolution of this phone be changed?

Hello! Was wondering if there was a way to change the resolution of the S6 from QHD down to 1080p. I've found the Nomone Resolution Changer, but I was wondering if there was a more trustworthy way about getting the resolution to get to 1080p. Long shot, but still! Recommendations, please?

Actually I was wondering the same thing until I remembered the fact it has a small battery and a 5.1" screen that really doesn't need the QHD resolution with such a small battery + screen
There are some apps available to change the DPI, i know that skydragon roms come pre baked with a DPI changer, but this will require root.

But that's not how it works. The phone will still have the same qHD screen, and will still have the same amount of pixels, and require the same amount of power. You're basically just changing the DPI to make everything larger, using 4 pixels to display what 1 used to.

No he actually wants to change the proper resolution, not DPI.
Less resolution = Less processing power required = Less battery spent.
That being said.. OP no there isn't a way

Right, that's what I meant. You can't change the DPI (which would what he'd be doing) and have it magically change the physical number of pixels used.
No that's not what he's asking. He's asking this much like a TV. Instead of having it be QHD he wants it to display in 1080.
It's a clever way of thinking but that wouldn't help really. It'll still have the super pretty screen just everything would be smaller. Even if there was a way

But that's the point: Even if you wanted to display in 1080, you still have the same amount of physical pixels in the screen, and the same amount of power needed to light them up. Unless, of course, you wanted to only use 1920x1080 pixels, at which point only 25% of the display would actually be lit up.

You're missing the point.
First of all, lowering the resolution would make everything appear larger. You have to lower the DPI setting in build.prop to scale things back down to the same size (or lower).
Secondly, lowering the output resolution will save battery power and increase performance because the CPU and GPU are working less. This is fact and just how computers work (the screen is not the only power draw in a phone). The amount of physical pixels in the screen is irrelevant because that will draw the same amount of power regardless of what the resolution is. (However, since the is an AMOLED screen, it will draw less power when displaying blacks due to the nature of the technology. Not that this has anything to do with the resolution discussion.)
Thirdly, the amount of power you will be saying varies. Mostly you will gain performance and power-savings while playing 3D (rendered) games. The GPU will be able to perform at a higher framerate as well as save you power. This is tested and true, although some applications will be glitchy due to poor coding. The amount of savings while on normal screens is subject to the efficiency of the SoC. I am not sire much will be gained here. Performance in these screens is said to be slightly increased, although I believe this phone probably has snappy speeds already.
Lastly, if you do this there may be a visual issue that could get on your nerves. Since you are altering the 1:1 resolution of the pixels, a blur will naturally occur. Since the screen is relatively small for the amount of pixels in it, the blur will be minimal and you will hardly notice after your eyes adjust to it.
Using Resolution Changer Pro (free app) you can set res to 1080 and dpi to 480 for a significant improvement in gaming performance. (phone doesnt heat up like frying pan anymore)
Difference in quality is completely unboticable.

Hello Thoth33,
I used Resolution Changer Pro, but it didn't change the resolution!
What do I do wrong? I use Android 6.0 beta on my Galaxy S6 (SM-G920F).
It even tells me that it gets root access!

Solved the problem via Android Terminal Emulator!!
i changed the resolution on my Galaxy S6 Active from QHD to just HD!! Did some graphics benchmarks and the results are more than 2 times those of QHD.
Oh, and I did this without ROOT.

How to do it without root?

You can do it via adb.
These are the 2 commands for both screen resolution and dpi
adb shell wm density (insert dpi here)
adb shell wm size (insert resolution here) && adb reboot
The reason for using both commands is that you have to use the correct dpi with your desired resolution and screen size, so that the icons and UI is neither too large nor too small, otherwise, the UI will crash
For example,
For Galaxy S6,
If you want 1080p, you have to choose 480 dpi as that is the correct dpi for a 5.1 Inch diaplay.
If you want to go back to QHD, just repeat the same commands with your stock dpi and resolution, which are
640 dpi
1440x2560 resolution && adb reboot
I did it via adb because currently there is no root for the S6 Active.

1080p as standard !!!!!

Yup, this was pretty obviously stated and samsung did tell people. You can turn the resolution up if you require also.
1920/1080 is 1080p....so 1080P+
:laugh:
its a little more than 1080p. Also I speak from experience that you can not tell a difference unless you are looking for it. It is the same screen resolution on the S7's with nougat.
Yep it is. Lets not blow this out of proportion people if you want QHD+ its in the settings under display.

I couldnt tell on my oneplus 3T, the screen was great.
QHD on a phone is overkill. It's a nice-to-have if you're trying to watch a movie, but other than that it's purely excessive. If someone showed you a 1080p and a QHD display on the S8 or even the s8 plus, I can all but guarantee you wouldn't be able to tell the difference. I sure can't with my S7E.
The problem is not that 1080p looks bad. The problem is that this display has a set number of width and height pixels which is defined as 2960 x 1440. So if you want to display a picture which is 2220 x 1080 in a display which size isn't a multiple of the picture you have to interpolate. You somehow need to have just 1080 pixels in a row where there are supposed to be 1440. Why don't they go with 720p instead? Well I guess it would also look shi**y :/
Just my thoughts, I have never seen a S7 or S8 display.
EDIT: I just think about this from a delevoper perspecive. The developer thinks: Let's make a black 2px line there -> it's a 2px line.
Because you cant fit a multiple of 1080 in 1440 the interpolation would make a 2,66px line. As you know you cant color 0.66 parts of a pixel black. So most likely the whole pixel will be black which results in a 3px black line where there should be a 2,66px line. As this happens with every pixel of the display the image won't just get inaccurate but also the GPU has to do some very unnecessary scaling work.

It's the same as changing the resolution of a computer or monitor display. The interpolation isn't the issue, every manufacture has that down pat. 720p would make a noticeable difference, even in basic browsing and function. 1080p is enough that on a screen the size of the S8 or S8+ you wouldn't be able to see the individual (or interpolated) pixels.

I didn't say that this is not the same. But when I buy a 1080p monitor, I use it in 1080p because thats what it is intended for. You won't see pixels on a 500+ ppi device. But the image will be totally unaccurate and that's not what I generally like to look at. I just tried this in photoshop and the effect is even worse than I thought and demonstrated by that example picture in my last post. Here's what it'll really look like. You want to look at this? Of course it will be very small pixels but do you really don't mind?! I know I do.

That's not at all what it will really look like. Doing something in photoshop is not even close to how it will look in real life. Please look at the phone before you assume what it will look like. I just switched my phone from 1080p to QHD and back again, and I literally cannot tell the difference, even with my face pressed inches away from the phone.

You can't negotiate with the pixel science
Most likely the pixels are just to small to see a difference but I will take a look at the phone when I get it to judge wether switching to 1440p or not

But don't forget these OLED panels use a diamond pentile subpixel arragement, so the interpolation isn't quite the same as a traditional RGB LCD monitor.
It's REALLY REALLY difficult to tell the difference between QHD and 1080p on the S7. At more than about a foot, it's nearly impossible to tell. I know what you're saying, I hate running monitors at non-native resolutions.
If it bugs you that much, just change it.
If lower resolution gets me another 1hr SOT per day, I'll drop all the way to the bottom. Can't tell the diff.
I just changed to 1080 p on my S7E (was at the highest rez setting). Really can't see a difference. Icons and keyboard are a bit larger. Texts are a bit bigger. But as far as sharpness, look of the display, not an issue. Just going to test and see if this makes a difference much on SOT or not. I can always change back to the highest rez setting if I want - takes about 30 seconds to do.

I use Nova launcher, Swype and Handcent texting app. It changed the size of icons, the size of font, the size of the keyboard and the size of the texts (the bubbles and text font). It did increase the size on all of those. Also increased the size of the quick settings, etc. It's not a big deal, but it did increase the size of things a bit. Has caused no problems so far otherwise.
