Development [ROM][12.1][UNOFFICIAL] LineageOS 19.1 for Xiaomi MIX 4

[er453r]

Not an selinux issue then. It's working fine here on LOS and on PE. Go to app info (long press anx icon on launcher and select the "i") clear all storage and try again. If it still doesn't work then I'll need a logcat to try and troubleshoot it.

Kinda sounds like the issue I had early in development when various things work on one boot slot but not the other. Reboot to recovery and flash MIUI 13 firmware again.

Also, why does everyone seem to extract and patch the boot image when trying to install Magisk? Why not just sideload it in recovery?

For future builds the relevant latest firmware will be included in the ROM zip, to avoid all these headaches about firmware version.

@Inkypen Installed 0519 version, here is the logcat, but it only says networkError on downloads, nothing else :/

I looked into this and I found only the gapps version has this bug and the vanilla version works correctly. This makes no sense considering I've built several other ROMs which also include gapps and it works properly on every other build I've made. I've also got some of my own logs but unfortunately they are useless because they give no info whatsoever as to the cause. I will do some tests with different gapps packages to see if I can pinpoint exactly what is going on.

I spent my whole day trying to figure it all out but I made it ( I am not good with computers)
At first I wanted to install your pixelexperience ROM but it failed (see pic) so I had to flash lineageOS instead.

As you can see it displayed an error at 47% "failed to read command: No error" even though the rom was successfully flashed and is currently working.

I don't care as long as it works but I just wanted to say it anyways.

Also touchscreen doesn't work in Orangefox once I actually flash it, I have to run it through fastboot to make the touchscreen work.

I tried this rom and the interface seems to be really framey when opening and closing applications as well as swiping back and forth to the google feed. I've tried forcing 120 hz and other things, is there a setting i don't know about?

Hey ! First of all, thanks for all your work, flashed latest LOS (20220519), that fixed thed location green pop up thing, but the front camera "hole" still becomes visible when it shouldn't, at least know it seems to only happen above 85 % brightness, this wasn't an issue on build 20220321, could you please confirm if you get the same behavior be cranking up the brightness up to 100 % ? Thanks !

@lightskreen have you enabled variable refresh rate in Display settings? I do not know how it knows when to use 60/120 Hz but I have noticed no stutter at all.

@santimaster2000 @Inkypen I can confirm that front facing camera is more visible since 20220519 - as if it was a few levels darker than the rest of the screen.

Thanks, at least I know it wasn't just me.

Also, the problem was present (As far as I've tested) since 20220511, can't tell if it was also present on previous versions between that one, and 20220321 (Wasn't present here), because I've only ran those 3 (20220321, 20220511 and 20220519)

Are there any plans to fix the widevine level from l3 to l1? I know that the China/eu Rom habe l1,so it should not be impossible to fix

New builds are up:

• June security patch
• Kernel upstreamed to 5.4.197 and latest lahaina CAF tag
• LHDC Bluetooth codec added (untested as I don't have a BT device that supports this)
• Some ANX tweaks (should start a little bit faster)

Regarding the conversation about the visible camera hole at maximum brightness, that's a hardware limitation. You must have seen Xiaomi's promotional image of the pixel array above the front facing camera showing the smaller pixels allowing light to pass through to the image sensor. A smaller pixel will not be able to shine as brightly as a larger one hence the slightly darker view on max brightness. MIUI gets around this flaw by displaying a sun symbol over the camera hole at max brightness. On a couple of builds I tried limiting the max brightness by about 15% so this wasn't noticeable but I had a few people in sunny areas complain about the change, so I reverted back. If it bothers you just turn the brightness down a little bit.

I've had L1 support since before I even released any builds. Download any media codec info app from play store and check for yourself.

Ohhhhhh OK, that makes sense !

One issue, that forced me to temporarily switch back to MIUI is Android Auto.
For my new car it is not working. It starts connecting, the Android Auto app opens on the phone, but then closes (crashes) again.
I suspect there is something wrong/missing with gapps, but i couldnt get a log.

On MIUI everything works

Update: Switched to PixelExperience, Android Auto is working perfectly there

Thanks for this great ROM, just got my mix4 and installed it, works great

I'm wondering if anyone figured out a way to enable immersive mode (hide the status bar)? It looks great on notchless phones like this one, I was running android 10 on my last phone and had it, but apparently google removed immersive mode starting from android 11...

The usual ways to enable global immersive mode through adb or root apps doesn't work, there is some confusion with people claiming it does work on android 12 but that's on samsung and other modified android distros that have apparently kept the immersive mode functionality. Both Android 12 AOSP and MIUI seem to have this functionality removed.....

Is there any way to get immersive mode back on Lineage? I really don't want to go back to having a status bar visible...

I've already flashed it and rooted, and it looks quite nice! Awesome job! This rom should be official!

I've built TWRP 3.6.2 A12 branch and decryption is working. Untested other than making sure it boots and decrypts internal storage correctly. Use fastboot boot to run it and Advanced/Flash current TWRP to actually install it. If you find any bugs feel free to report them but bear in mind the whole TWRP A12 branch is currently WIP.
