Regarding Screen Resolution

Hi,
I recently bought Samsung Galaxy Mega 5.8 I9152 only because it has dual sim otherwise I was opting for Lenovo K900. Mega has lower resolution so I used Display Changer (Resolution Changer) and using Apex Pro so no prob with home, drawer, dock or lock (with min improper position). But problem found in camera and dialer, both are not positioned properly according to the resolution I set (from 540X960 to 720X1280).
So my question is, can we fix this?
Pls help me.
Thanks

Settings > Screen > Zoom and font.
I think the Zoom slider in that screen sets the "resolution".

This is terribly wrong.
The slider just controls how big are the objectives on the display, not the actual resolution.
not build into stock S6 family. maybe some custom rom...
in custom roms ported from s8 and s7 you should have it yes
if you are rooted you can follow this guide to change resolution https://goo.gl/UKaif3
and this to change DPI https://goo.gl/2N9R89

Changing resolution blocks screenshots

@duraaraa any info or direction that you can provide on this?
I upped the resolution from stock 1080x2160 to 2160x4320 and left dpi at stock so I can have more screen real estate and still have a comfortable viewing experience. The issue I'm facing now is, I cannot capture a screenshot I get an error.
System UI
Couldn't Capture Screenshot
Screenshots are not allowed by this app or your organization.
steps to reproduce:
up your resolution to 2160x4320 and take a screenshot
Any guidance would be appreciated.

Sorry, don't know. Probably issue related to rooting and the settings you changed.
Thanks for the quick reply but I'm not rooted.

Mate 10 pro panel is only 1080p to begin with,
In what way did you upped the resolution ?? The setting wont give you that resolution option.

no need for root or settings to change DPI or Resolution
adb shell wm size 2160x4320
adb shell wm overscan reset

uh... well... you already understand that this method is "only faking" the number for the app to think that it run on that size of screen right ? Hardware & stock OS wise, the limitation is still on 1080p
I dont think the system UI app of EMUI 8 itself was made to handle that number
Normal 4K itself is only 3840 x 2160, and i dont think i ever found any phone running 4K+ (18:9)
This is just like asking why sometimes the play store act weird when we change our DPI
So answer is that : because it simply didn't support it
I've done #wm size 720x1280 & wm density 320 to 720p screen for long battery life. and I found the system's screenshot can not take whole screen(720p one).
It looks like the screenshot component take a 480p screen and the same 720p adjusting on AEX 5.x is fine.
so I thought maybe the screenshot on pie still mistake 720p screen for 1080p screen and take a 480p picture(expect: 1080p x 720/1080 = 720p, but now: 1080p x 720/1080 x 720x1080 = 480p)
But I notice that keep wm size 1080x1920, whatever which density(320 480 240)I've set, the screenshot could take a complete screen picture. while I change density, whatever resolution (720x1280, 480x800, 1080x1920), screenshot just take the top left part of screen...
partial screenshot is same condition , take a top left part of what I selected .
the screenshot on different resolution is the last issue I can found on AEX 6.0, which not contain on AEX5.x(maybe this is pie issue but still expect you can fix it) if I don't need change the resolution, the ROM is PERFECT?
can you fix this ?? thxxxxx a lot

Who is gonna fix what? Just use the phone the way its supposed to be used i dont understand what you are doing and why. If anyone, huawei can fix your issue i guess.... good luck talking to them.
You should read this, particularly the long answer near the top which explains the size vs density changes.

I think this is actually a bug in android pie. My phone has a 4k display, but normally uses HD res unless in gallery app. So I changed wm size and density to match the display (and despite what some other say, this actually changes the visible resolution, IF your display has this many physical pixels).
Screenshots worked worked fine in oreo, but after updating to pie, there are black borders on the picture.

No Huawei phone has a 4k display, this whole thread is a waste of space really, guy setting his phone display to something that is not supported and wondering why his screenshot won't work, damn mate 10 pro is 2160x1080 and can't be any more than that, if the problem was the screenshots not working in a supported mode there might be a reasonable and were but as it stands this thread should be closed and deleted

The whole point of my post was more like: its not a Huawei only "bug", but effects all (or at least most) pi phones with a custom wm size set. Maybe I was beating around the bush too much... :angel:

Hi, have you found any solution for the screenshots when you change the screen resolution? You're right it happens only in pie and with different phones, in oreo the multitasking previews resize when you enter to the app but the screenshots are ok, in oreo the previews in multitask are ok but the screenshot miss a part of the screen.

Galaxy Tab S3 - Huge subtitle size

Hello!
I just bought a used galaxy tab s3 to replace my kindle fire HD10. Overall I am in love with the device and the screen but there is one annoyance i am not able to sort out properly.
Basically subtitle size in vlc and Netflix apps is huge. I reduced screen zoom and font size to minimum and even downloaded a new font from Samsung, but still is way too big. Eventually, I managed to sort of fix it by changing the size to small in vlc, but in Netflix I had to change size on the account and this is all for all devices.
I would like to know if you all are having the same issue and if you also notice subs are really big specially in Netflix. And if you have a better solution than reducing the size in the account settings from Netflix.
Thanks!!!!
If this is not possible on the samsumg rom, any recommendation for custom roms that has minimal amount of bugs?

Update to android 12 changed default PPI

Default it should be 421ppi but after update it was 320 hence every apps looked awful (way too big)

G991B/DS
Yeah… I played around with the screen zoom settings and font size. Seems everything back to normal or I just got used to it.
