[APP/TUTORIAL] Change A850's DPI (Density, Resolution) (Root needed)

Hello everybody,
What is DPI:
Dots per inch (DPI) is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm). The metric alternative is dots per centimeter (dpcm).
Monitors do not have dots, but do have pixels; the closely related concept for monitors and images is pixels per inch or PPI.
[Read more...]
Why to change the DPI:
Most manufacturers stick to the standard DPI of 240 which in our case, on a big screen, everything is too big compared to other phones.
Since the scale is the same with other phones, our big screen makes no difference (because we see everything bigger and we do not see more).
This can be fixed to each ones need when you change the DPI.
Images:
Left is the default DPI: 240 - Right is my custom DPI: 200

How to change the DPI:
There are some ways to change the DPI, i will describe an easy one by using a free APP called LCDDensity for Root and a manual method.
CAUSION: Messing with the DPI may cause instability and some times boot problems, so BACK UP before trying anything.
Steps: (after making a back_up)
METHODE 1 - App from store, the density resets to default after a reboot.
1. Install LCDDensity for Root.
2. Open the "LCDDensity" app (click continue on the first screen) and sellect the density you want (default is 240), you better go from 180 to 240 (between these values) , i am using 200.
3. Sellect as reboot method: killall
4. Click "Apply (Restart)", your phone will reboot
5. Enjoy
METHODE 2 - Edit manually the build.prop, the density will be changed even after a reboot.
1. Open a Root Explorer (like the app Root Explorer).
2. Go to /system
3. Click on Mount RW (It should appear as Mount RO, that’s when it is correct!)
4. Look for build.prop. Long press on the file and press Open file in Editor
5. Scroll down and find the "ro.sf.lcd_density=240"
6. If you find it change the value to what you like else write that in a new line at the bottom (ex. ro.sf.lcd_density=200)
(Change the value to anywhere between 180 and 240. The lower the value, the higher density your screen will have.)
7. Click on the Menu button, and Save and Exit.
8. Reboot. Enjoy
Method 2 was copied from here: http://wccftech.com/article/increase-screen-dpi/
PS:
- I advice you, first to use the app to see which density you prefer (and avoid compartibility problems) since with a reboot things will get back to normal.
- If you have any problems on the reboot, restore your system from CWM
Bugs:
- The answer/reject call buttons are not in the middle of the screen... big deal

1 question
How i want change permenent. After reboot back to normal large. Sry bad english

You can manually set it from a system file but i havent test it yet...
Edit: take a look at the first post

Please help

This = that ... that simple... you find density and you change it. Save -> Reboot... problem solved BUT you should know in what value you want to change it....

Used the app...
It said on the fly, but none of the buttons worked. Need to reboot?

Mini-Guide Adb installation and usage

How to run ADB on Windows for the MediaPad X2 ( and probably other Huawei devices ) :
* Windows: Download the HiSuite from Huawei ( for the adb drivers )
http://consumer.huawei.com/minisite/HiSuite_en/
* Windows: Download the adb 15 second installer ( and install with admin level )
http://forum.xda-developers.com/showthread.php?t=2588979
* Smartphone/Tablet: Set your device to USB debug mode
- Go to Setting - About Phone
- Press 7 times on the Build number until you see a message that you have access to the developer options
- Go to Setting - Developer options
- Enable "USB debugging"
* Windows: Run the abd command
- Search for cmd, right click and select "Run as Administrator"
or
- Go to c:\windows\system32\cmd.exe, right click and "Run as Administrator"
* CMD box:Enter the following commands:
- cd c:\adb
- run the command you need.
For instance to change the DPI for your phone / smartphone:
- adb shell wm density 280 ( or whatever number you need. The X2 runs at 400, the Sony Z Ultra runs at 320 ).
Reboot your device after making changes

Hi. Any way to get the drivers alone, without installing all hisuite?
Thx

Can you post some screen shots of the X2 running in 280dpi please ?
What the advantages of changing the dpi ? is it you can get more on the screen ?
Is it possible to change dpi using an app and could it be set on a "per app" basis ?
I don't want to screw up EMUI
Thanks

The dpi changes can always be undone. So you are not going to screw up EMUI.
Here are some pictures that ajsmsg78 posted:
http://forum.xda-developers.com/showpost.php?p=62462003&postcount=12
You gain about 60% more content on your screen in Chrome etc... At 400 ( default ) dpi, the X2 its screen content is nothing but a oversized smartphone. With 280dpi, its a tablet with way more usable area.
At first i also doubted if it was worth the effort, because it took me a long time to figure out all the steps. That is why i wrote this manual, so its way more easy for other people. Will it screw up EMUI, yea, for a part:
The new installed program icon's will have a green area. The basic 5x5 will not change size with the new DPI ( because Hauwei is so stupid as to hardcode the grid size around the 400 dpi ). But you can use any other launcher instead of the EMUI launcher. I kind of like Action 3 ( Action launcher 3.5 ) as a replacement.
The few disadvantages are really few, compared to the massive gains you get. The Sony Z Ultra was running in 320dpi and still had chrome in smartphone mode ( no tabs etc ). 280dpi on the Sony's 6.4" was not feasible. But on this 7" X2, 280dpi is the perfect size and it opens up several programs there tabled mode.

Make sure you check these threads daily. A lot of stuff gets posted that you may not have seen and then the same questions get asked over and over again. You could even start a new thread in the Q&A section asking for someone to post pictures of what the phone looks like at 280dpi. You'd probably get a faster response if you did that. It makes it easier to look through each thread if we all keep the topic about what the original post was about. :good:

Thanks very comprehensive answer
I want to set my dpi to 280 now but can't without access to my laptop
Will have access to computer in a few days and will do it then
The X2 has to be connected to the lap top

Wow! Something new to think about! I assumed that you saw MORE content on the display because the display is bigger. But now I understand that's not the case. If you do what's on the instructions that Benjiro figured out does that void the warranty?

So I followed the steps to a T and was able to get my booloader unlocked. But now with the Rooting I can't seem to find my device. It finds it with Fastboot but not adb. I've tried 3 different computers and usb cords with the same results. I just want to root this, any adb advice would be greatly appreciated.

I get the same "cannot find device" error but ADB still works. Try the commands and see if they work. Or update your Android Platform tools to the newest version.

Hi!
Thanks for the guide!
Is there a way to fix the navbar disappearing in horizontal mode? When I hold the X2 in landscape mode the Navbar is still there (a black stripe) but the Back/Home/Recent Apps Buttons are missing. Tried several DPI settings.
EDIT!
For some reason it works now! The navbar is now on the right side of the screen when in landscape mode! I switched DPI several times one after another (280, 320, 400, 330, 300, 280, 320 something like that) and rebooted and somehow it works (320DPI).

But there is one big problem: the famous and extremely useful keyboard "Swiftkey" becomes totally unusable below 400 dpi.
A big disappointment more on this X2 ....

No problem if you change dpi via the kangvip menu
For this install AJ's B211 Rom

Change display resolution (2k to fhd)

Yes, the first thing i want to say : "Nokia can change screen resolution 2K to FHD" but they don't release this in setting.
So i have a way to solve this problem, follow steps by step.
.
First u need install app " QuickShortcut Maker"
-open this app and accept permission, in activities tab find setting *com.android.setting* and click this.
-Pull down the bottom and pull up and find setting *display resolution* and choose it, then click "Try"
Now u can choose resolution that u want.
p.s : If u want make the icon bigger, change "DPI" in ur devlopment setting. The default is 376.

sorry about for my english. but i have somethings about battery i want say to you.
First- Does it get more battery ... ?
yes but not to much. And working for those who play game.
so Why ?
for example ur display is 2k with 5xx dpi. when u decrease to fhd it down to 4xx dpi. Then when u play game with display FHD, gpu will use lower performance compare with display 2k.
Two- Some problem happen with this change ?
sure... the first is glance (so for those who always use this setting, dont try change resolution)
-some other problem (like get airplane mode,....etc ) . I will say "no".
me and my friend on my group no one get any the other problem except glane setting. So for those who get other problem.... are u launch other shorcut in shorcut maker ? .Because i try and get error same. So... factory reset and forget my post

Awesome. It works I didn't find "Shortcut Remake" app but I found a similar app "QuickShortcutMaker".

@op are you vietnamese?

any change on battery life?¿

Wow, thanks OP. FYI the app link https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut and you can just type resolution in the Activities tab.

Since I changed the resolution, the phone is put in random airplane mode. I came back to the original QHD settings

Wow, this is a great discovery, I benchmarked my Nokia 8 using GFX Benchmark and found out that performance is significantly improved. Check it out
Nokia FHD https://www.dropbox.com/s/0xkewxfonpmpnxe/nokia8_FHD.png?dl=0
Nokia QHD https://www.dropbox.com/s/dt90w0sli8fttdm/nokia8_QHD.png?dl=0

SoT improvement!
I believe the screen on time has improved greatly under heavy workload specially in games.
I was still left with 22% of battery after 6 hours of heavy usage.

Some battery life for me , no changes

This actually works and what's it's more important, stays after reboot.
After installing app just type "resolution" this will take you to hidden setting.
Phone is definitely a little bit faster, not sure about baterry etc.

Lots of interesting findings in the Settings app, including face unlock but so far other than what the OP said, only Gaming Mode is working. Others are either not working or have no effects on my device.

thank u <3

please tell me how to get rid of random airplane mode, I changed the resolution back to 2k and it still goes to airplane mode at random.

Xperia 1 is in 1080p by default

I did a wm size in adb to check what the default resolution is, and it seems to be in 1080p (21:9 ratio).
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

This would explain why the battery life is still great. Despite being in 1080p, the display is still very crisp. Crispier than my XZ3.
If I did this wrong, please do correct me!

When I screenshot in any app including launcher, it results in 1644x3840 tho.. Previous 4k sony phones produced fullhd images if you ss on launcher
So which info should we refer to? Wmsize on adb or screenshot pixel size?

No.
My XZ Premium screenshots are 2160x3840 png files, and the same for my older Z5 Premium.
That adb system is so suggested from users that many people believe in it, but the true reality was explained by a developer in this forum in "Z5p days". The proof is that you can do that with any phone.
It also explains that 4K screen is completely useless because nobody can spot the difference from fullHD (and I say this while it's since 3 years I'm only using 4K phones)

Using wm size on Xperia 1 results in screen touch area only works in partial, equaling to the scaled screen size, but the text is simply crispier. Anyone knows how to fix the touch area problem?

Do Kindle/Moon Reader etc.. run in 4k or 1080p mode?

I did exactly ./wm size 1644x3840 and yes...unfortunately that is the case where currently we cannot have the phone at 4K all time at this moment.
I'm guessing that Sony did something to the UI touch overlay in order for the side sense detection to work precisely.

Regardless if you use wm size to "force" it in 4k, it's not actually 4k, but just emulating. In order to get native 4K, you have to be on a kernel that supports it.

Enviado desde mi G8141 mediante Tapatalk

I found that when I disable a game enhancer it automaticaly change a resolution to 4k...

Since it's pentile display, 4k will still be less blurry than a 2k/FHD, even for 2k/FHD content. Good to know that the GPU is not used all the time for 4k. An dsince I Watch my movies with VLC and photos with Google app, mince will never use 4k xD

How To Guide [TUTORIAL] how to set the screen refresh rate to 90 Hz

[Tutorial] How to set the screen refresh rate to 90 Hz
90 Hz is the best compromise between smooth experience and battery consumption, MIUI on poco x3 pro does not support the option to set 90 Hz by default.
How to do it
1) Go to settings -> about phone -> and click 7 times on "MIUI Version (for POCO)" until you see a message that you have become a developer
2. go back to the main settings menu, then into additional settings -> developer options and find the option "show refresh rate" and then click. Now you will see the current FPS number in the upper corner (60 or 120 depending on what you have chosen)
3. Go to apps -> manage apps and search "battery and performance", then select clear data of this app
4. Go to the google play store and download SetEdit (Settings Database Editor)
5. run the application, and at the bottom look for the option "user_refresh_rate"
6. click on this option and edit the value to 90, save the changes and then you can exit the application
Enjoy! When you exit the application, the FPS indicator should now show 90 instead of 60 or 120

I had to restart the phone afterwards to make the change take effect, just in case anyone else thinks the above hasn't worked.

If I were to do this with a rooted phone, would this be under build.prop?

not working and then I restarted the phone but still not working.

it wont because guide is not complete(even though it is kanged). if you look at old x3 nfc's guides/TG groups, you will see proper steps. after setting the refresh rate by using "setedit" app or clearing data & cache of "battery and performance" app, you need to at least once open "recents" otherwise it wont take effect.

I tested it today on xiaomi.eu ROM and it doesn't work there

ArrowOS has the feature built-in:
Settings –> Display –> Device-specific settings (Refresh rate configuration) –> Minimum refresh rate

It work for me on MiuimiX ROM

If I'm not mistaken, I don't think so, you just need to set a constant refresh rate, e.g. 60,90,120 Hz

As easy as it comes, thanks for the input friend, 90hz is perfect

works in MIUI Global 12.0.6 stable. Thanks bro

How about battery consumption, better than 120hz adaptive?
And how about if i want back to normal again

Good question. How to change refresh rate simply by editing value in default.prop?

It worked for me and i didnt do the "3. Go to apps -> manage apps and search "battery and performance", then select clear data of this app" part.
