[MAGISK] [MODULE] Force enable SRGB

[daleski75]

I have created a magisk module which forces the display to sRGB when it's not available on certain custom roms.
This may work on other phones but it is of course complete untested.

Before anyone asks the reason for this module is because my banking app does not work with magisk manager installed which is needed to set sRGB in ex kernel manager etc.

just set magisk to hide root for the banking app, I had the same thing but it only blocked me from using the fingerprint sensor which I use to log in pretty much always.

It's hidden already but it detects the magisk manager app

Isn't there an option to hide the magisk manager app ?

Yeah it still detects magisk even worth it hidden

Hi,

Has anyone been able to test this on a Oneplus 3T?

I am running RR 6 which doesn't seem to support sRGB yet.

Can't see any reason why it won't work.

Thanks for the quick reply.

Before or after flashing, do I need to do anything like under Live Display/Display Mode (it is set to disable all adjustments).

If not, it doesn't seem to work. The modules shows enabled in Magisk after a reboot, but the colors are incorrect.

Not sure I only tested it on my OP5 when I had it as some custom roms lack sRGB support and from memory I don't remember having to change anything.

You're welcome to hack it and get it to work btw.

maybe i'm stupid, but i can't imagine how sRGB can help you to hide magisk from banking app. hmmmmm....

The app I used to enable sRGB broke my banking app as it then detected magisk so I wrote the module in order to get sRGB working without affecting the banking app.

oooh, i see, pretty smart but a bit complicated

The path for the Oneplus 3T is different (or maybe it's different on RR, I don't know). Anyway, the path is:

echo 1 > /sys/devices/virtual/graphics/fb0/srgb

I've changed it in the post-fs-data.sh file and rezipped it. Testing now .

Edit: it works!
