Talking [GUIDE][DualSim]Removing Second Signal Icon on Statusbar Even 2 sims are inserted

This is tested in Spreadtrum Dual Sim phones But you can try it to your own device.

Backup first your SystemUI.apk
and Pls. do it at your own risk

Requirements :

- Rooted Device
- Apktool
- your favorite Text Editor
- Root Explorer
- your SystemUI.apk

Here are the steps

step 1

- Decompile your SystemUI.apk
- go to SystemUI_src/res/values/public.xml
- find the id of stat_sys_signal_null

<public type="drawable" name="stat_sys_signal_null" id="0x7f*****" />

- and Copy or write it on a paper

step 2

- now go to SystemUI_src/smali/com/android/systemui/statusbar/StatusBarPolicy.smali
- inside .method private final updateSignalStrength(I)V ( be carefull with this because there are two stat_sys_signal null ids in StatusBarPolicy.smali)
- search the id of stat_sys_signal_null that you get from public.xml before
- then change it to 0x73366275
- save and close

step 3

- recompile your work
- push it to /system/app
- and reboot


step 4

- we're not done yet
- you will notice that the 2 signal icons are still there in your statusbar,
- now switch ON flight mode
- wait 5-10 seconds
- switch OFF flight mode
- and wait until your signal icon appears
- if the 2 signal icons are still there, just switch on and off flight mode until you get 1
- done


NOTE :

- if you want to get your 2 signal icons back, just switch on and off flight mode until the 2 signal icons appear or simply reboot your device
