Need a workaround for mobile gyroscope acting differently on IOS and Android devices

Hi, I am trying to find a work around for a bug that swaps the X and Y axis when I’m using an android device, It works perfectly fine on my iPhone 7 but switches the X and Y axis on my Google Pixel 1.

The head on the right side of the video is my Google pixel and the head on the left is my iPhone, I am doing to exact same rotations on both devices and it is completely switching the axis. Both devices are also in portrait mode and calibrated.

I found a bug report from 2019 addressing it. I believe if I could check if the user is on IOS or android then I could swap the axis to make it work properly, but the problem is I do not know if that is even possible.

Here is the main code that controls the rotation if that helps but I’m pretty sure that it only is happening because of the Roblox bug, also I might have accidently left out a few lines since its spread apart.

	local DeltaVar, Gyroscope = UIS:GetDeviceRotation()
        local UIS = game:GetService("UserInputService")

local RootCF = Cam.CFrame
	local UPSDN = (UIS:GetDeviceGravity().Position.X < -.5 or UIS:GetDeviceGravity().Position.Z > .5)
	local CRROT = Cam.CFrame
	local LIF = nil

if LIF == nil then
			LIF = Gyroscope
		end
		local DTA = Gyroscope*LIF:Inverse()
		local X,Y,Z = DTA:toEulerAnglesXYZ()
		if UPSDN == true then
			DTA = CFrame.Angles(-X,Y,Z)
		else
			DTA = CFrame.Angles(X,-Y,Z)
		end
		CRROT = CRROT*DTA
		LIF = Gyroscope

                Cam.CFrame = CFrame.new(TargetCFrame.Position)*CFrame.Angles(CX,CY,CZ)
		Cam.CFrame *= CFrame.Angles(Y,X,Z)
		RootCF = (Cam.CFrame*CFrame.new(-SideDistance,-Height,-Distance))

I also just noticed that it also inverts the Z axis on android

Update: I came up with a workaround which is adding calibration to the way the device faces up

Could you elaborate on this, I ran into this problem as well.
