Run your Xperia XZ Premium in native 4K resolution with this mod

by XB on 4th July 2017

in Videos, Xperia X series


The Xperia Z5 Premium was the first phone to feature a 4K (2160 x 3840 pixel resolution) display. However, despite the headline-grabbing spec, the 4K part of the phone could only be used with Sony’s media apps. The rest of the phone, including home screen and settings are all rendered in 1080p Full HD. The same also applies to the XZ Premium, although at least 4K video is supported through Amazon Video and YouTube.

However, what if you would like to take advantage of that 4K screen across all areas of your phone? Well a solution has existed for a long time, that involves the “adb shell” command to change the resolution and display density (DPI). Doing this means that you can run your phone natively in 4K resolution, however this does not come without perils.

While uses report that navigating around the home screen is noticeably sharper, some apps may have compatibility issues (particularly with text appearing smaller). A common complaint is that enabling native 4K will constantly crash the Phone Dialler app, although you can get around this with a third party app. There may also be some slight performance issues, however if you’re worried about battery life taking a bit hit, most people suggest that there isn’t a large impact.

YouTube user Damir Franc recently posted a simple tutorial on how to change the Xperia XZ Premium resolution, which you can check out below. You can also check out the source links below for extra information.

Thanks ew210, KF, Michael, Naim and Sasa!

    Will this become permanent after this tweak? Does restarting revert it? Or most importantly, does this revert to 1080p after every system update?

  • Liam Hethershaw

    Can the smallest width setting in developer options be used to achieve a similar effect? or is it just for scaling?

  • Out of topic here, but do you guys know of any option to enable night mode on Xperia XZ 7.1.1?
    Or is it just impossible to have that native function?
    Thanks a lot!

  • dpc4321

    I absolutely love my XZ Premium the way it is! Best Xperia I’ve ever owned :-)
    It’s perfect!

  • dpc4321

    Yes, go to settings, then assistant, then Xperia actions. Hopefully that helps.

  • Thanks, but no! Doesn’t have the Night Mode option? Would you share screenshot of the menu on your XZP?

    It’s called good night on XZP

    Hi. I have a z5 premium and i love it, but, yes there’s a but, I’m not a mobile gamer but i did get caught in the pokemon thing and in this summer, my phone gets hot alot and it’s uncomfortable to hold at times. I’m thinking in upgrading to this xz premium but i would love some feedback about thermals while playing games (if there’s a testimony about pokemon go even better) on this phone… Thanks in advance for those who can help me get info on this subject.

    I decided to try this, downloaded Minimal ADB and Fastboot 1.43, and run the exe file. I was expecting to see a Windows installer app dialog but all I got was a text-based app running in command prompt window. I proceeded with yes responses to prompts, it finished its job, but nothing was installed. There is no shortcut on desktop, on start menu, in applications, and no respective folder in Program Files (x86). To be honest, this looks very suspicious, I don’t know what kind of app that was and what it could do to my computer and with all my data. Any thoughts on this ?

    here is another video from honest reviewer https://www.youtube.com/watch?v=OVdN7w3oEFQ&t=120s and battery life running the phone in 4K https://www.youtube.com/watch?v=fZa2YFb-0hg

  • Mou Sa Kas

    Don’t do this. you’ll regret it!

  • Batuhan Süersan

    So we can also set it to lower res if we want? I’d like to use my Z3 on 720p @ Simcity BuildIt

  • Naim Noor

    No worries, I believe that’s how it gets done.

  • Naim Noor

    You can always revert it back using the same method and changing the values to default numbers.

  • Harish

    I am not blaming the processor, but 810 chipset was the major reason for overheating in z3+ and z5 series. So i guess there won’t be any thermal problem in XZ Premium, considering sony’s optimisation.

  • Serdar Aytamaner

    OK no worries security-wise. The real problem is that it was supposed to install something but it didn’t. It says “completed” but there’s nothing related to this ADB utility on my computer :(

  • Naim Noor

    You can check by connecting your phone to the computer with USB debugging enabled. Then search for cmd in your computer search bar, Command Prompt will come out. Then in the command prompt, follow the instructions to enable 4K as per usual.

  • Hideg Jenő Péter

    Did you try enable debugging on Developer options? (yes a hidden settings)
    If you don’t have a developer options, then tap few times “build number” on About phone and it should be appear.

  • Serdar Aytamaner

    Thank you very much for your responses. Now I have enabled developer options and USB debugging. Then I re-run the exe I have downloaded. It completed without errors but there’s nothing where it was supposed to be installed. No application folder in either program files folders, no shortcut to the utility anywhere.

  • Serdar Aytamaner

    Thanks for your response. I have enabled developer options & USB debugging now, connected the phone, and tried to re-install. No errors but still no application to be found anywhere :(

  • coach

    As far as know, adb and fastboot are runned through cmd. Try searching for “adb” or “fastboot” and locate the folder they are in. Then you run a cmd window in that folder using shift+left click. My other guess is that they are located in the app data folder, which might be a hidden folder

  • razorg

    You don’t understand what I meant, read carefully…

  • Serdar Aytamaner

    I had already made a fruitless search for *minimal* as that was the folder name I saw on the video. After your post I searched again for “fastboot” and I found it under c:adb. Thank you :)

  • Serdar Aytamaner

    I tried, it worked, but the dialer crash is a dealbreaker. I’ll be watching for a fix on that.

  • dpc4321

    I also had the Z5 previous to XZP and I was also disappointed with heat problem’s and also poor battery life :-(
    I’ve never played pokemon go but I’ve played other games on my XZP and absolutely no heating problem’s whatsoever :-)

  • SergioPerigoso

    The snapdragon 810 is not a chipset, it’s a SoC (System on a Chip) it includes CPU, GPU, mobile modem, and other essential stuff, and although it could not be the cpu, the whole thing didn’t work properly (but my guess is the CPU, because if i force the GPU to draw 2d the phone overheats a bit less and in a previous firmware where the big cores were disabled the phone did overheat less too; but now that they did move to 10nm with this SD 835 i heard good things about thermal but i wanted to confirm with testimonials from real users)

  • SergioPerigoso

    Thanks. Before the pokemon scene i didn’t had problems with heat or battery because i didn’t play games on my phone, and sometimes i had 3 days battery life… But now it can drain in 3 hours if i play the damned game…

  • JC

    I’m afraid that’s one of the reasons the screen size isn’t natively 4K.

  • DIsChaos

    I guess all I can confirm you that XZ premium has no overheating issue with SD 835 , my Z2 had issue

  • Pokemon GO is a NOTORIOUS battery hog and phone killer on Android. Moto Z, LG G5, OnePlus 3, no phone is safe from the hog that is Pokemon GO.

  • SergioPerigoso

    Very happy to hear that… I’m really interested in this phone and i really want a cool phone so, i guess I’m out of excuses… I have a z2 tablet and have little to no issues with heat, maybe it’s because it’s a tablet and have more room to “breath”.

  • SergioPerigoso

    Oh yeah, I’m aware. I have no problem with battery life, because i work in my home and there’s always a usb cord in a arms reach, but the heat from my phone in this summer in the little time i go out to play a little bit, it’s uncomfortable. It would be better if I’ve lived more to the north, but Portugal is a very sunny country and I’m not very fond of heat, i prefer the cold.

  • Thanks for sharing. Greetings from the AndroidKosmos.de Team

  • DenisXD

    That was already mentioned since z5p, i don’t get the need though. You can’t really see the difference.

  • G-UNIT_(Z)

    can make a screenshot, under that resolution?
