[Q]Run apps at lower resolution? - Android Q&A, Help & Troubleshooting

In general,can we change some properties to make a given app run on a lower than native resolution?I think it should be totally possible,since phone come in various aspect ratios and resolutions.So the app detects the screen and resolution,and adopts accordingly.Gensoid does that in-app.Double,original size,strech,etc....
For instance,if we have a game on a 1920x1080 screen,but the GPU struggles to keep the framerate,we lower it to 960x540,the game still looks fine,because we get 1:2 resolution,and far fewer pixels to push.I think there should be an app for that.

You guys are no fun

Try chainfire 3d

will reducing resolution actually increase battery life or play games more smoothly or i am being wrong?
anyone? .........
thread up..........anyone?
As for battery no. The screen is still lighting up the same amount of pixels and same brightness etc... Gaming i doubt u will see a difference. Tell us if u find othwise tho. Hope that helped

Changing screen density isn't the same as changing resolution. Apps choose which icons to show depending on the "screen-density" value reported by the device. So higher density devices will have larger and more detailed icon graphics, etc.
As far as saving battery life, the screen typically uses most battery which varies slightly depending on the brightness setting. One root user found he could save battery by only showing red colours (requires changes to the display driver).
Shrinking the screen like in Note 3 will save energy...anybody found a way how to do this in other phones? application?

Can Someone please test Nest thermostat App?

Can someone in the states try installing the nest thermostat app on their streak
https://play.google.com/store/apps/details?id=com.nestlabs.android
I can't download it in the U.K. I have tried market enabler and other tricks but I am wondering if it is just the Streak's resolution that is stopping it. There is a review saying it works on the note, so I'm hopeful.
If anyone wants to send me the apk it would most appreciated
Thanks,
Mark
**** Ignore this, found a way of downloading the app and it doesn't support the streak's resolution :-( ******
What do you have the dpi of your Streak set to?

No idea, just the standard resolution.
From Nest
To use the Nest Mobile app for Android, you’ll need:
An Internet-connected Android smartphone (Android 2.2 “Froyo” or later required) with one of the following screen widths:
520 pixels on a HIGH density device.
480 pixels on a HIGH density device.
360 pixels on a MEDIUM density device.
320 pixels on a MEDIUM density device.
270 pixels on a LOW density device.
240 pixels on a LOW density device.
working on GS3
hmmmm, under the impression the GS3 is 720 pixel width, yet the app opens on my device.
just checked their site, same android requirements, and they also mention it should show a popup window if it doesn't meet the requirements.
However, I never got the popup window, so it works with 720?
Looking into Nest, just sent them an email questioning just these items.
Well according to the market, my S5 at 240 dpi is compatable.
The S5 is a standard WVGA (480x800) device, and nearly all devices of it's age are the same thing.

[Q] Faking display resolution for Cocktail Flow

Hey there,
Cocktail Flow is probably the one and only good looking cocktail app for tablets out there. However, its developer really hardcoded the resolution to 1280x720 which means it cannot be used on any newer tablet (like a Nexus 7, see screenshot). And since the developer abandoned the project, this app is probably gone forever.
Is there are way to reduce the resolution of tablets (or faking a lower one) such that the app is stretched and can be used again?
I've already tried Xposed + App Settings, but changing the DPI doesn't help, since the developer is not using dp...

Playing games in vr

I am using a nexus 6p with rooted latest android n preview.
The app "3d games" by tridef is able to show a lot of mobile games such as final fantasy and minecraft in 3d. The problem I have is that all of these apps are 16:9 just like my phone! So when "3d games" produces a side by side image, it is small and does not give any immersion at all.
What I was wondering is if there is a way to launch an app in a set aspect ratio without just changing the size of your screen. Anyone that can help?

Resolution decreased to HD - weird UI elements

Hi to all!
Well I've read some guides about how to decrease the resolution on my Z2 running latest Marshmallow Existenz ROM 5.6.5. Changed resolution to 720x1280 and system DPI to 253 (I have rather a good eyesight that is why do not mind small UI elements ).
Some apps were not satisfied with the DPI I told them to work in that is why I tailored some of them using Xposed module App Settings.
But there are some issues I could not repair :crying::
1. The bootanimation displays normally, but after some seconds only half of the screen is filled (so it says ''Xpe'' and then ''Existe''). Tried to install smaller (720x1280) bootanimation but the result is the same. I can live with that
2. The Recents' thumbnails are enormous. Even 1/5 of the app is displayed in the thumbnails. I thought initially that it is caused by SystemUI's messed settings with the DPI so I played with App Settings to repair it (both ''DPI'' and ''Screen (dp)''). Still with no luck.
Thought it might be connected somehow to Android WebView which is operating in country's local app with used stuff called Finn. There the thumbnail is also really huge, before the whole picture would fit in the thumbnails.
3. Is the suggestions/xperia menu search. The ''suggested'' apps are much bigger that the icons displayed in menu.
So it might be some scalling issue, but I have no idea which application would I need to adjust.

My phone is running Android 6.0.1, with root, with xposed modules related to UI: AppSettings, GravityBox, Xperia Home by Serajr
Any help in the matter will be appreciated! ::laugh:

No one ? - I don't believe no one really had that issue! At least say: 'Happens to me too'.
Keep it hd 1080x1920 and change DPI to 320

Thank you for your input! However it is not the solution I am looking for. I just wanted to have lower resolution for a better performance. I am I the only one who is meeting such issues?

I tried it and got the same like you.

I reduced my resolution to 540x960 and set the dpi to 240. Performance and battery life felt largely the same. Graphics were mostly unaffected except for weird glitches like the ones mentioned in the OP (walkman aka music would straight up stop working though). Text looked blurry, perhaps a subpixel rendering thing.
At the end I returned to 1080p. It was not worth tickling my OCD for little to no benefit.
Thank you for your replies! Wow Pixelado, your resolution was pretty low. Beacause no newer Xperia has that resolution, the Sony apps could cease to work. I wanted to keep something still lower yet 'compatible'.
Yes the performance is pretty much the same. Antutu did not gave a higher score, even gave a lower on CPU and higher on 3D a bit. What I noticed was after playing 3D game for around 20 mins the temperature was around 53C, before in 1080x1920 it was over 61C (in a thin rubber cover). What are your observations?
Best regards,
Vixificent
I came back to 1080p as suggested. Thanks! :good:
