Screen resolution - stretching?

I actually realized this since the first day of using the tablet... I noticed that the screen actually got stretched when you set your tablet in landscape mode and squished in while in portrait mode.
I suspect that the OS is running at a wrong native resolution... Does anyone have similar observation?

Yep, me too
I noticed the same issue. Circular icons look especially bad. Funny enough, the tablet on the packaging also has a distorted screen. In Youtube, videos have black bars on the top and bottom of the screen. This shouldn't be the case, as 1024x600 is a 16:9 aspect ratio, and videos are typically 16:9.
Code:
adb shell dumpsys display
contains the following output:
Code:
mPhys=PhysicalDisplayInfo{600 x 1024, 59.670002 fps, density 1.0, 177.209 x 171.115 dpi, secure true, appVsyncOffset -5000000, bufferDeadline 22758840}

Yup, installed luna icon pack and looks horrible. Same as letters in Google keyboard.

I was just getting on to post about this very thing. Here is an image comparison I put together showing a screen shot side-by-side with a photo of the screen:
https://drive.google.com/file/d/0B0Z0bpkQXwBFR1djTnJLSGlsTkU/view
According to the images I pulled, the nominal screen resolution is 600x1024, which is also the hardware spec. But the actual image you see is the same aspect ratio as a display with a resolution of 600x1080. This suggests that the display pixels aren't actually square. I tried a couple of resolution changers in the Play Store but they just scale the display without addressing the issue.
I found an old Google Groups post asking about a cheap tablet with non-square pixels, and the answer in 2012 wasn't very encouraging. I wonder if something could be done through an Xposed module?

I lowered the dpi to 150 just to test and same result...

Also, this line from the display dump above similarly seems to indicate non-square pixels:
Code:
density 1.0, 177.209 x 171.115 dpi
Anyone know how to change horizonal and vertical dpi independently?

Apparently the dpi is 160 normally.
You can set it higher and the icons will look less stretched but the dpi seems correct.

Yeah, this is sadly typical in cheap chinese tablets. What really surprises me is that almost nobody talks about this, and most of the people don't even notice it even after pointing it to them
I've also noticed that this screen has what I think is a slow redraw rate (i. e. painting line by line from the top) which cause funky scroll effects, especially in dark backgrounds in portrait. Grab the tablet with the buttons on top and scroll quickly in the Kindle Store and you'll see it

I watched a video on the Fire for the first time, and while this isn't exactly a scientific test, the video did not seem stretched out or distorted to me. I tested with a second video and it too seemed to display with the correct aspect ratio. If so, then that suggests that the display, controller, and drivers are all capable of rendering an image that is not distorted, and that it may be an issue with the rendering of the Android UI.

Up, i would love having a fix for this.

Mine doesnt seem to show these problems? Is it just a some devices problem or am I missing something?

Just got one of the $50 Fire tablets delivered and this is one of the first things I noticed. Look at a circular icon when it's in portrait and when it's in landscape and it's really obvious. I noticed it on the Pinterest icon.
If this really is a hardware issue, I don't suppose there's any way to fix it? If not I'll probably return it and get my money back.

Idk.. I don't really notice it maybe it's just my perspective the seem good to me.

It didn't jump out at me, but yes, the screen is definitely wider than 1024/600. Maybe it is 16:9.
I did notice the weird scrolling. Perhaps it's refreshed in some interlaced fashion?

I've noticed that some people just don't see it. Coincidentally in my case it was the same people that watch 4:3 content stretched in their 16:9 TVs and are happy with it

^^^ This!
The incorrect aspect ratio is really distracting. I hope there's a way to fix it now that custom ROMs are available.

Hey guys! Does anyone else have a problem with scrolling. When I scroll down a page it looks like the left side is scrolling slower than the right. So for example, if you scroll down on a page full of horizontal lines or text, all the text slopes to the right until the page stops. I'm not sure if this is normal because the tablets so cheap or if its just mine?

It seems "normal" for this tablet, sadly:

Can't complaint it's rather solid for it's price imo.

Aghh glad its not just mine then. I'm loving the fire! Though it was going to be rubbish but really surprised!

Dialer/Call Screen mods/fixes

After recently rooting my J7, I've decided to use one of the resolution changing apps to give my phone a 1080x1920 pixel faked resolution, with a dpi of 280. For the most part, it works. Some built-in apps such as the camera or even the touchwiz launcher (seems some UI elements used hard-coded numbers to define regions, or in case of the camera, the view is almost a quarter of the screen with black around the edge, and the touch input is offset to a different corner.
All else seemed good, until I realized another major flaw - the call screen - it works, however when trying to pull up the keypad when in a call, it only displays a single, gigantic 1 button. no other buttons are available. Button-based menus are of course now impossible to navigate... unless every button to press is 1, 1 and 1. And then 1.
Can't take pictures of it now as the resolution change causes an issue for screenshots - I'll need to get a screenshot app for this, but ultimately, are there apps that replace the call screen? I thought a dialer app would fix this but the one I have only replaces the text/call/contacts apps, not actually calling. I'd prefer there to be an app that can replace it, as it seems most third party apps are almost never hard-coded to a specific resolution, meaning I'd imagine it should work on my modded phone.
If more explanations are needed I can try to provide some screenshots as needed when i'm done. I'm really hoping I don't have to reset the screen. I love how everything works otherwise...

Install Google Phone apk and set it as the default dialer app.
It also replaces the incall screen

Awesome. It worked like a charm. Thank you so much!

disable portion of screen with camera

is it possible to disable the entire horizontal area with the front facing camera on it, so that you don't lose out on a portion of your viewing experience? kind of like the notch / no notch options in other phones

So to avoid losing a very small part of screen? You removen 3 times+ more screen? ? Seems counter intuitive

Like someone else mentioned I don't see the reasoning behind that, but you could possible use another launcher like Nova and have the permanent status bar across the top.

The justification is that one is more distracting than the other.
I'd rather take the hit and have a smaller screen (lose 0.2 of an inch) than have video gain 0.2 of an inch but be hampered by a pill sized cutout that obscures video. It is a massive distraction. Arguably worse than the notch because at least that was flush at the top.
The question is whether we have the opportunity to control placement in software. If so, is that native support in android or would that have to be a custom feature via different launchers?

I doubt it will be native support and it will require another launcher.

LOL, Thanks, good to know. That surprises me since that cutout was a Samsung feature and Samsung isn't big on hiding their features.

Camera depth of colour changed since upgrade to emu 10

Hi
can you help.
Since upgrading the depth in colour on the camera is very poor.
I sell vacuum cleaners mainly online and used to love how the pictures came out. Now they look very weak in colour with no depth.
I won't lie. When i first got the camera I can't remember if i made any settings changes but I have been playing around with it and can't seem to re-create it.
One thing I used to touch the screen to focus on a point and the picture used to darken slightly which looked good. Also it was a circle. Now it's a square and the picture goes lighter which I hate.
Can you guys help..?
I did try to roll back to EMU 9 through hi suite but it won't give me the option. I did enable HDB etc but it still does not give me the option. If you guys can't help with the camera settings, is there any other way to rollback..? I don't care about security etc and new features, the main use was for the pictures.

Hi,
I was wondering if you saw the option to revert to factory settings in camera when you open settings? Try doing that?
As for darkening the photo, when you touch the place you want to focus, the little sun appears on the side of the square. Try swiping up or down to lighten or darken the photo.

Do Front Cameras Reduce Notification Icon Space?

I'm considering picking one of these up (refurb) and I've never had a phone with notch or with cameras in the screen area. Front camera has been in the bezel area right above the screen. It looks like the two front cameras on this device are essentially embedded into the screen. Does that mean there is less display areas for notification icons or does the device allow for two rows of notification icons + time/battery display up top?

It may seen that it would be e problem, i've owned mine for about 4 months bow and its not an issue. The notification bar is thin but still very readable. If you want to customize the notification panel further for space, you'll be able to download (GoodLock and NiceLock depending on your region) to help with that.

I took a peak at the descriptions of those apps and screen shots and can GoodLock actually modify the top notification status bar on top? I didn't think any app could control the look of that? Those apps seems to have quite a bit of overlap with built-in functions of latest Android 10 + One UI 2.x ? Still might give them a whirl.
SO I've had my S10 5G for about a week now. Right away, I tried the virtual bezel setting that basically black out the top of the screen next to the cameras. I didn't like the look. On my LG V30 the camera was in the bezel and the bezel was very thin so the screen display still appeared to take up most of the glass. With this setting on the Samsung, it's too heavy handed, blacks out a little too much height off the top of the screen so it looks odd with a very tall black bezel on top.
So far, I don't think the reduced space has caused my notification icon bar up top to get overloaded. What I ended up doing though was selecting a wallpaper that the top right corner is dark or almost black. It effectively "hides the cameras" while utilizing the full screen. Of course with apps open that aren't black on top, you see the large camera cutout but it's not really that distracting/terrible looking.
I like that Samsung got a little smarter on the S20 and has a very small single camera cutout in the middle of the screen now. Looks MUCH better. But still, it's only looks. Some may prefer having the dual front cameras, which I think is a nice trade off to having the larger camera cutout on the side instead of the a small single camera in the middle.
