[guide]Add more columns to the oneplus launcher!

*requires root* tested on OB22
So after seeing the recent XDA post about enabling Google photo back up when charging, I figured I'd do some snooping around in the shared preferences files myself.
I found out you can change the amount of columns in the stock OnePlus launcher (to add more than the standard 3/4/5 columns).
To do this you need to go to:
/data/data/net.oneplus.launcher/shared_prefs/net.oneplus.launcher.prefs.xml
Then change the number in this line (at the bottom of the file) to whatever number you want.
<int name="workspace_columns" value="5" />
I don't recommend adding too many columns, as the icons will start to overlap (see the screenshots below). For medium icon size this will happen with values higher than 7-8, setting the icon size to small will prevent this to a certain extent.
After editing this line you need to force close the launcher for the changes to taken effect.
You will however still have 5 rows. This (probably) can't be changed in this way, due to the rows not being customizable in the launcher. The columns are, which is the reason this line exists.
Below are some screenshots, as you can see the icons are almost touching each other which 8 columns. The 12 columns are more a proof of concept.

Is it possible to add more rows?

This is why i'm still on nova laucher... when this will be costumizable on stock launcher? pleaaaaaaaaase...

Hello, this method is not working anymore on latest version. Can you help me what might be the problem? Also what file manager and xml editor did you use? Thanks!

I unfortunately broke my OnePlus, so I can't really help you too much with troubleshooting. Last I tested was on oos pie, so it probably should still work. I used solid explorer to edit the files.
Are you sure you are rooted? There are apps available to manage shared preferences files of all your apps. Maybe you'll have more luck if you try one of those.

I am sorry for your oneplus. The line is there and I have tried changing it but it doesn't do anything. It only happened with the latest version. I am on Pie. I am rooted with the latest Magisk, tried many explorers and many xml file editor . Anyway thank you for your reply. I will try to search and maybe I can find something.

Change Background with Smart Cover

Hi.
There is a way to change the background when I use the smart cover? I mean the window on the right I can see with the smart cover...
Thanks in advance.

Without root you have to change the design in the design app. You can also create your own with apps.
With root you can replace the file, I don't have the correct name, because I deleted it for having a black background, inside the directory "ROOT/data/themes/0/wallpaper"

My phone is no root: can you please tell me which is the design app and the apps I can use to create new ones?
Thanks again

The "Designs" app is a pre installed system app. There you can choose your lockscreen wallpaper, which should also change the smart lock background.
With EMUI Theme Editor you can make your own theme.

I've tried but it changes only the standard background and not the smart lock one, that's why I opened the 3d and made the question...

With the EMUI Theme Editor change the S-View image. You have to crop it to the right size inside the editor before you save the theme. This should work, I've tested it a few minutes ago.
This is another EMUI thing that should be fixed by Huawei, but they don't mind what they're users want to have in the next updates.

I've tried and it works!
Thanks a lot [emoji6]

EMUI 8.1 custom Themes issues (partially incompatible with EMUI 8.0 themes)

Hi,
This thread is to report custom themes issues - as I noticed currently available themes (working fine on EMUI 8.0 phones) are partially incompatible with EMUI 8.1 on our P20 phones.
Known issues (EMUI 8.1 vs EMUI 8.0):
- sms app is no longer supported (there is no longer Huawei sms app - Google Messages instead, completly inconsistent with EMUI design...)
- some (not all) custom screen locks are not working
- custom settings menu icons are not visible (only default ones)
- general issue with non-system app icons - most of them are not changing with theme (even if there is custom icon inside theme)
- custom status bar and notifications are not working
I received my P20 today, so i'll update above list during my tests. If you notice any not listed issue - let me know, i will add it.
I'll try to find a solutions for that issues - but of course any help is appreciated

Life saver!
I've been playing around with the themes and noticed my notifications had disappeared from the lock screen. I had assumed it was another setting I'd changed by mistake, but couldn't find what I'd done.
Found this thread last night, stuck the theme back to Romance, and the notifications are back!

But you can use custom theme with standard lock screen - and notifcations should appear

Any custom lockscreens that work with notifications? I tried a few but none display spotify lockscreen controls. I ask because I'd prefer a lockscreen with the clock at the top instead of the bottom like the magazine theme.

Try lockscreen from my SimpleP theme - there is a clock in the top and spotify controls work

I have the same problem. I tried some custom themes and now, no matter what theme I choose, notifications won't expand, I can only read notification first line. And yes, with some custom themes, notifications won't show at all.
@mr.mrcn I can't find SimpleP theme

It is in my app (link is in the signature). But notifications in this lock screen don't expand either.

They are not expanding for me as well, seems like a stupid bug (much like no synchronized volumes with Bluetooth audio devices)

EMUI 8.1 ignores all xml images in custom themes, they are displayed by default.

Not quite true, in my theme are all icons changed, and some other stuff too. I don't have much time to look around, but some paths of icons are different from previous versions. Will try with png's and new folder paths. ???

Because all icons are round and there is no special mask in this icon pack Look at my screenshot - there is a mask, but for unknown reason is not applied to some icons (like gmail, slack, whatsapp..), but for other it is (facebook, telegram..).

I think not..they would not include a theme engine if they do not want customers to change the look of it..but that is my opinion

You can still change UI colors and drawer icons... Maybe they just want you to do it/they want developers to optimize their themes for the p20/p20 pro before allowing them to change navbar icons/notification tab icons and stuff, at least imo

No Status Bar for me at all, tried Factory reset, the same.

Custom Magisk Module Mod Maker-ADB and Zip Installers

Most of my mods are SystemUI mods and so if more than one is flashed, only the first one works. This ADB mod was created so a person could pick and choose what he wants and have it all in one module. That being said, I don't have this phone and this particular mod has not been tested by me (though I have similar mods on several other Pixel phone forums). You need root and of course you need to be attached to your PC. On first installation of systemui base, a pop-up asking to give ADB shell root permission will show. Please do so. THIS ONLY HAPPENS ONCE. If you miss the popup you will have to go into Magisk manager and give shell root permission there.
The purpose of this installer is to generate for you a custom module that you can flash in Magisk Manager. It will have all the mods that you have selected from the installer menu.
Zip installer is installed from your phone, not your pc. You will install the mods through Magisk app. Unzip the Zip Installer onto your internal sdcard. Like ADB installer, start with a SystemUI base. Do not reboot between selections as Magisk as shows after flashing selections (options are found inside the numbered folders). Hit the back button to make your next selection. Do not reboot thru Magisk until after you are done with your selections and have flashed the "Complete Installation" zip.
Custom clocks (date, etc) and internet speed indicators do not change colors due to light-dark background colors like the statusbar icons do.
I'm also including my Pixel Launcher mod. Also a ADB Installer. You can change app drawer background-text color (separately for light mode and dark mode), remove weather from Launcher. Change the number of hot seat icons on home page (and size) as well as change the number of columns in the app drawer. There is already a Pixel Launcher mod here but this is here fir those that don't want to use substratum.
ADB Installer Instructions-Root is required
1. Flash one of the SystemUI Bases First. They provide the necessary smali files and public ID's for everything to work.
2. Starting from the top (usually best), select the mods you are interested in. Once completed, select the "Finish building module" Option. This will create a Magisk Manager flashable zip (mymagisk.zip) in a folder on your sdcard called ozop. Flash that to install your custom module.
Root required
ADB Instructions.
1. Unzip the enclosed zip file onto your PC
2. ADB debugging in developers Enabled
3. Run TulsadiverModsInstallerStock.bat (Give ADB Shell Root Permissions. If missed on first opportunity, turn on in magisk manager, superuser)
4. Flash one of the SystemUI Bases First. They provide the necessary smali files and public ID's for everything to work. The only difference between the two bases is that you can change the color of the QS pulldown circle colors on the "color" base. Plus the "off" circle color isn't grey but instead the same as the "on" color only darker/dimmer.
5. Go through the other options selecting what all mods you want. It is generally best to start at the top and work your way down.
6. Once finished with selections, run "Complete Installation" at the bottom. This will generate your mymagisk.zip module in a folder called "ozop" on your sdcard.
Root required
ZIP Instructions.
1. Unzip Zip Installer onto your internal sdcard
2. Flash thru Magisk app. Flash the SystemUI Base First. It provides the necessary smali files and public ID's for everything to work
(Do not reboot between selections as Magisk shows after flashing selections. Hit the back button to make your next selection)
3. Go through the other options selecting the mods you want. It is generally best to start at the top and work your way down.
4. Once finished with selections, flash "Complete Installation" at the top. This will install your selections as a Magisk module.

Includes a batch (.bat), and powershell installers, one for windows, one for linux. I don't have a linux computer so the linux Installer could have bugs.
If you chose "Small Statusbar", you are not done yet You have to go to settings system/developer options/Display Cutouts and choose the last option, "waterfall cutout" in order for your mod to look right.
**This is a SystemUI mod and might not be compatible with any other SystemUI Mods you may have installed.**

Downloading now, work hates AFH sadly so going through data on cell phone. Will post back after and add a screenshot with my setup. Can't wait to get rid of the battery icon and carrier text!
@Tulsadiver
Removed previous mods and flashed newly created on.. Sitting at "Pixel is starting..." for a couple minutes now.

Funny enough, the phone is partially working, it just rang for a call but showed nothing except that message still lol. I installed the list below. I didn't see anywhere to select center clock in the build menus, is that the "small statusbar clocks" in Option 2?
Standard Base
Remove Battery Icon, Leave Percent
Remove Carrier Center Clock
QS 6 Column
Statusbar Data Icons Cell Tower 3
QS Data Icon Bar type 3
QS-Statusbar WiFi Icons 3
Waterfall Display
Gave it a few more minutes but ultimately removed modules with adb wait-for-device shell magisk --remove-modules. I'll give it another go if you think I missed something in the creator.

Yes, if you install the waterfall cutout i would select a clock from the option 2, "small statusbar clocks". Otherwise your clock and/or notifications will be off.
Try baby steps. Install just a base and see if that works.
Did you use the .bat file or powershell?

I see, there's a menu below option 2 in there. Might be handy to rename that to indicate there's another list instead of saying Install on it. I thought that was going to install a small clock instead lol.
Building now and will report back.
EDIT: Added the clock this time, left everything the same and had the same result. Wanted to see if the lack of center clock was throwing something off. I'll compile 1 part at a time and see which one is breaking it.
EDIT2: Rebuilt without battery icon removal and custom icons. Was able to boot but center clock didn't set, hoping I missed it. Carrier removal worked though. Recreating now WITH icon removal to see if it changes properly.
EDIT3: Rebuilt zip with remove battery icon and it wouldn't get beyond Pixel is starting again. I'm going to do another with just the base and remove battery icon to see if that is the cause.

Center clock did nothing or not centered, or something else?
Are you saying there is half of a battery on the statusbar or just that it's not on the statusbar but it is on the qs pulldown?

Screenshots attached so you can see. Center clock didn't center at all.
EDIT: Doing it again without the custom icons to see if it removes the icon properly for the batter and centers the clock.
EDIT2: No change without custom icons.
Built with right clock, small statusbar, no battery icon, custom icons for data and wifi (option 3 for 20/21/22), remove carrier (noticed there isn't an option to remove carrier for left small clock)
Right clock not working either
I won't be in front of a computer for a couple hours but can do more testing then if you have any thoughts or ideas. I'll compile and test just clocks then to see if it's something there.

Nice find. Stuff like this is pretty picky. I've spent the last month building a series of batch files to assist with tech responsibilities at work and while it's fun it can be super nerve-racking when you misspell something like that.

Question Icon Grid change

Hi All,
Just checking how do I change or increase the icon grid on the display screen from 4*5 to more ?
Thank you.
tech

It's done through the 'Styles' customisation when you long-press on the homescreen. You can adjust icon shape, accent colour, and grid size.
Bit strange that it's in that menu - especially since icon size is elsewhere - but given many previous revisions of Moto's software never had the feature natively, I'm happy.

Is there any way to put 6×6?

Just with custom launchers.
I have used nova launcher until recently. I'm facing a bug where I cant close an app, and that app will stay on my screen whatever I do.
I've tried microsoft launcher and Smart launcher, but same thing was happening.
Now, I use Hyperion, and so far. for 1 week, that bug happened just once, instead every day like with other launchers.

With root you can edit the stock launcher:
go to data/data/com.motorola.launcher3/shared_prefs and in shared_prefs there is an .xml file called "com.android.launcer3.prefs.xml". Inside you fill find the line "<string name="pref_grid">XxY</string>" where instead of XxY you put 6x6 or whatever you want. You will also find the line "<string name="PREF_ICON_NEW_SIZE" value ="X" />" which allows you to change the icon size to whatever you like. After edit the .xml file to be read only so that the phone doesn't change it and give it a restart. It may or may not work, I haven't tried it with Android 12.
