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

[Illux]

Hey there,

Daki from www.androidkosmos.de published a short article that the resolution can be changed to 4k by default (so Kudos to you man). As it's in German and not exactly step-by-step, I felt like posting a short how-to.

Step 1: Turn on Developer Options.

- Settings -> About -> Click 5x on Build-Number

Step 2: Allow USB debugging

- Settings -> Developer Options -> USB Debugging [X]

Step 3: Open ADB, (always without the " ofc!)

- Type "adb devices", click on "allow request" on your phone

Step 4: Change Resolution and DPI

- Type "adb shell"
- Type "wm size 2160×3840"
- Type "wm density 807 (after a little tinkering, I found 721 to be the best DPI. Yea, really, 721)"

There is no information so far as to how battery life is affected!

Back to default:

Repeat steps 1-3

Step 4: Change Resolution and DPI (back to default)

- Type "adb shell"
- Type "wm size 1080×1920"
- Type "wm density 403"

Best

IlluX

Further to this, if you're a weirdo like me and want everything reset rather than a set value due to your own personal OCD, you can use "wm size reset && wm density reset" :good::fingers-crossed::silly:

Thanks, when I set the 4k res, I get the error message "bad resolution"... why?

 

[FartyParty]

Awesome!

 

[ytheekshana]

will this work on Z5 Premium?

No idea, typo maybe? Tested it back and forth, not a single issue to report.

I don't have a Z5P so I can't guarantee but I'm quite confident it does.

 

[DakiX]

Haha look at that. Nice and thanks for share
I also published on talk.sonymobile.com forum.

Morning! Yes, it was... I used * instead of "x", I need new glasses eheh

How's the battery for you guys? When I do this to my Z5P, the battery doesn't even last a few hours

Thanks. I checked my default density before changing it with the command "wm density" which exported 420, not 403 like OP said .

The draining is very poor, not an impact so remarkable. The issue is about the themes, e.g. in the Agree Bird I have now when I asnwer to a call, the dialer disappear and it becomes a nightmare eheh

the phone app is not working correctly after change to 4k. phone app force close if you try to make a call and dialer disappear

 

[tanipat]

got the aame result did not see any different on battery anyway, i think it is just mock, the desity shown in cpu z is same. but resolution is making at 4k in cpu z. need to change back due to phone app force closing though

I heard somewhere that the phone app will work properly if you use 1440x2560 resolution, not sure about DPI though. I think it was Z5 Premium thread.

aren't the ui supposed to be 4k unlike the z5 p? or did they changed it?

They said during CES or something similar that you would be able to change the resolution in settings, so you could run 4K all the time if you wanted to. But that isn't the case on the phone right now.

Either the people from Sony that made the claim had their information wrong or Sony changed their mind afterwards. Either way, it sucks that you can't control your resolution in the settings.

yes i do not know they give us independently, like s8 did. easily for them to control like that actually.

Hopefully it comes in a future update, maybe there were some issues with certain apps in 4K. I wouldn't count on it happening but it's not completely off the table.

Has someone used this for a while and can tell us about eventually battery effects of this? Does the phone app force closes etc?
