Treble fixes for Realme 2 Pro:

Here we are going to fix following issues after flashing Treble GSI on Realme 2 Pro.

  1. Low Brightness issue.
  2. VolTE (a.k.a HD Calling) not working.
  3. coming soon.

1. (Fixed) Low Brightness issue in Realme 2 Pro.


If you try to move brightness slider left to right then display brightness will not be bright even at 100% as it was in Color OS. Because  some devices use different brightness ranges so it needed for LightsService to re-scale accordingly after flashing GSI on your Realme 2 Pro.

Fix: Head over to Terminal (command prompt )and type this command and hit Enter.


adb shell

setprop persist.sys.qcom-brightness $(cat /sys/class/leds/lcd-backlight/max_brightness)

Reboot your Phone.


Install Terminal app or use TWRP’s terminal and type these command with Enter.


setprop persist.sys.qcom-brightness $(cat /sys/class/leds/lcd-backlight/max_brightness)

2. VoLTE patch for Realme 2 Pro:

After flashing system.img of any GSI you will not be able to call via Jio sim  (for India users) using VoLTE in order to do so use following methods to fix this issue.

Method 1:

add or modify the following line to /system/build.prop and reboot your Realme 2 Pro.


If still VoLTE is not working for you then try 2nd method it will work 100%.

Method 2 :

  1. Download and Install ims.apk on your Realme 2 Pro.
  2. Boot into custom recovery (TWRP/Pbrp etc)
  3. Wipe caches and flash this VoLTE Fix zip .
  4. Reboot.
  5. Voila You got VoLTE on Realme 2 Pro. :p
