[MOD] Change Default Resolution to 4k - No root needed!

[failax]

Found that the new XZ1 dialer works with 4k mode, using it for 2 weeks with no problems.

It's real 4K

It's real 4K

You have chosen 821 PPI density instead of 807 or less?Why?

 

[SNOOPLAYAN]

It's real 4K

Would you say that most apps run in a stable manner with the 4k mod? Does it show the content of your recent Windows or are they covered with black?

Also how's the Xz1 dialer performing so far?

I'm itching to go 4k all the time but I was put off by the reviewers saying that the phone starts to lag on the lock screen etc.

So far it's been running stable and fast, I don't really notice any lag or issues regarding the recent window. Haven't had a black screen or unlocking the lock screen.
Dialer has worked flawlessly and haven't had a single crash on it even after restart.

No particular reason, someone suggested 820 so I thought let's make it 821, so far happy with it.

This definitely sounds promising! Can you please post your exact method of applying the 4k mod along with the values used on adb like wm scaling etc?

And just to double check, the screen quality is noticeably improved right? And no apps are misbehaving?

Can't wait to try this!

Much appreciated @Hellpay

There really isn't any lag in the recents menu. The issue there is the thumbnails in the recents menu being all black instead of showing the preview. I tried in 4K and even QHD, but still black thumbnails in the recents menu.

THANK YOU. That prompted me to go check Google's DPI stuff in the app which confirmed this.

BUT it also works with 2160x3840 with DPI 720!

FIXED IT FOR ME:
---> in settings -> display set dpi to biggest (720)
adb shell
wm size 2160x3840
wm density 720
--> yes, 720 here too! Now my dialer works again while the screen looks super sharp!

Edit: Oh man. With these, recents menu worked for a while. Then after a reboot they're black again. What settings do you guys use that also show the content of recent apps?

so is there a combination of wm size 2160x3840 and wm density (806 ? 807 ? 720 ? 721 ?) that let you be in 4k and have everything working fine ( dialer,recent menu,cardboard) without rooting and without changing the default dialer ? edit : tried 480,720 and 807 they all crash the default dialer

the problem with 1890x3360 (and anything else than 2160x3840) is that the gpu renders the bitmap at this resolution but when it needs to present to the 2160x3840 physical screen it will do a rescale, lowering frame rate, using more battery than just copying pixels if you ask it to render in 2160x3840 with the wm size command

You can do the same also on your Z1, Z2, Z3, Z4 Tablet, Z5, Z5 Compact ..... and on your crapold device, because this is not changing the display resolution
Seriously guys..... this is changing the resolution of the VIRTUAL display (not the physical one), so like this you are getting 4k emulation on 1080p physical resolution.

all i can say is that on z5 premium and xz premium, when i used wm size 2160x3840 i can read small text in VR but when i restore wm size 1080x1920 i can no longer read the small text in VR . you can test it yourself with the app "virtual monitor resolution" by orpaga on the play store.

Actually it's not the resolution that's crashing your device, it;s the pixel density.
Try 4K @ 808 dpi or 802 dpi

not true i just do wm size 2160x3840 and leave density at 480 and default dialer crashes the same way, also crashes with density 720,820 or 807, just do wm size 1890x3360 and there is no crash in the dialer with any density values. so the dialer crash problem is coming from wm size and not wm density.

I just change wm size to 2160x3840 and then change display size in Settings app to preferred view, default dialer works well.
I don't change density in adb, just the resolution.
Done on latest stock Oreo .49

But i turned it into QHD because there some apps have strange layout with 4k res

wm size to 2160x3840 and then change display size in Settings did not work for me (build 47.1.a.8.49), it still crashes the default dialer. the only thing that worked was wm size 1890x3360 but it is only 6mpix and not 8mpix resolution plus it must cause a low level bitmap resize when presenting the 6mpix bitmap to the 8mpix screen.

Even on QHD, the thumbnails in the Recents menu are black, correct?

Hmm, idk then. I am also confused why it doesn't happen to me.

Yes ?

 

[failax]

I've put qhd resolution, but if i take a screenshot the resolution is 4k on every editing app.

And for the fella who gets force closes on apps - uninstall the apps and install them again and that might help. The apps that were previously downloaded were for the previous resolution.

good idea it may be why the default dialer crashes, does someone know how to reinstall the default dialer ?

ya pretty much you have to be installing versions for your resolution that you have set up.
