I am a fun of big screens and i think our Core has a big screen.
I also dont like 4 icons on one row... So lets begin .
---- Mod Preview ----
(Images here click button)
Launcher > Home Screen and Weather Widget
Launcher > Drawer
Launcher > Widget
Calculator > Normal
---- What is density? ----
Pixel density is how many pixels our screen have per inch. (Wikipedia)
Density's default value on Core is 240. We will change 240 to 200 (more pixels per inch, so smaller UI).
---- Mod for which device/version? ----
This mod was tested on a Galaxy Core:
Model number: GT-I8260
Android version: 4.1.2
Baseband version: I8260XXAMJ2
Build number: JZO54K.I8260XXAML3
(So ... on a stock rom)
(I have no idea if this work for GT-I8262 but i can cleary say that PhoneCall app have some hidden UI on GT-I8260)
Now its the time to say that u can't possible brick your phone with such mod... so gesh what... you are responsible for what ever you do to your phone not Me, not Jack Sparrow and hell not Spider-Man.
---- Preparation ----
To do this mod we need a Rooted phone. If you dont have your phone rooted, go download it from here (its an app) run it and select a root method (2nd worked for me), this will root your phone.
Now its time for backups just in case we missclick or we try to do the mod on an other device/version.
So the first thing we need is an explorer with access on the filesystem of the phone (I used Root Explorer, do your magic and download it).
- Open Root Explorer (or any other explorer with root access you want) go to "/system/" and backup (copy) on your sdcard the "build.prop" file ("/system/build.prop"). This is not mandatory but just in case.
- Now go in "app" folder ("/system/app/") and backup (copy) on your sdcard the files "AccuweatherWidget.apk", "SamsungCamera.apk", "SecCalculator.apk", "SecLauncher2.apk". (You can skip this if you dont want the apps mods to fit the new density, or only back up "SecLauncher2.apk" if you just want a launcher fix.)
---- Mod Time ----
With your Root Explorer (or any other explorer with root access you want) go to "/system/" and open "build.prop" on an text editor, now edit density from 240 to 200. (To edit the "build.prop" file you will have to "Mount R/W" this folder, Root Explorer will ask you to do it as soon as you click to edit the file) (Here a nice guide about changing build.prop)
debug.composition.8x25.type=dyn dalvik.vm.heapsize=24m persist.gralloc.cp.level3=1 ro.sf.lcd_density=240 <----- We need to edit this line (line 62) # System property ril adb log on
debug.composition.8x25.type=dyn dalvik.vm.heapsize=24m persist.gralloc.cp.level3=1 ro.sf.lcd_density=200 <----- We changed 240 to 200 # System property ril adb log on
Launcher Mod/Fix for 200 density:
With 200 density default launcher looks bad... So we need to add a one column and 2 rows. Will be gooood .
So we download the modified "SecLauncher2.apk" from the end of this post and put it on your phone's sdcard, dont rename the file (watch out not to replace your backup apk if you haven't moved it in a folder).
We now need to replace the "/system/app/SecLauncher2.apk" with the one you just put in your sdcard.
(I suggest you first to download a second launcher in case if something go wrong, you can still open Root Explorer and fix it. Nova launcher is free on GooglePlay, just download it before you proceed.)
So open Root Explorer and go to your sdcard ("/storage/extSdCard/" or "/storage/sdcard0/" depending on which you put it). Find "SecLauncher2.apk" and copy it (hold down and chose copy on the menu). Now go to "/system/app/", "Mount R/W" this folder and paste the file (click "Copy Here", its down left).
Now for the moment your Stock Launcher should not work untill the next reboot. You can ether reboot or continue with the rest moded apk provided in this mod/guide.
Rest Apps Mod/Fix for 200 density:
(Camera, Calculator, Weather Widget, PhoneCall, Email)
You will have to do the same thing for the other app provided in this mod/guide.
I am not going to rewrite the process as i have fully completed only the Launcher's mod.
The other apps are all usable but need style fixes so i need to work on them.
