    • read the post again man no eta and one more thing we are not going to release it until it bugless few bugs are caught by tester so we are trying to fix it when it fixes it will release for all and you also get the notification

  1. Bug –
    * Not able to change sim for data connection. Every time I need to restart for the change to take place.
    * Volte is not working.
    * Camera app is missing.

    • the camera is working perfect sir as well as volte do a clean flash and install any cam app u like some aosp based rom don’t contain fm and cam app

  2. All latest ROM for santoni made with official kernel source codes are not supporting NTFS file system as I can not use my 1tb portable hard disk with OTG. Where as all old ROM having unofficial kernel source code made kernel are supporting NTFS. I am using old kernel instead of new.

  3. One thing more, All Oreo ROM having FM radio have a bug with speaker mode. I found that it is caused by in sound setting . there is[ touch sound] where I unchecked it. The speaker mode as well as head phone mode working fine.
    It is requested please look in to this. Thanks.

  4. Hi, been reading your blogs for a long time now. After I got my redmi4x, I’ve been reading lots of forums and came across to worldgiz. I just want to know, is there any update going on for AOSCP 8.1 for santoni? A possibility that it could be official?

    I am on AEX 5.7 latest, thanks to you.
