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


- 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
