Hey just a heads up, I've got a gm1900 and I have tried kirisakura 1.1.3_R, blu_spark r_156 and latest nem0 from telegram, all of which work great in oos_11, but also, all of them brake the proximity sensor. The sensor is not detected by test apps and does not turn the screen off during a call. Reflashing latest oos 11 stable brings sensor back online.I'm working on it. My phone updated to 11 and I'm suffering without the kernel. This is still my main phone.
I don't think the proximity driver is even in the kernel, though there is probably something in the device tree. However, it is impossible to know what info is missing.
That is not a kernel fix, it's something else changed at runtime. You just need to change permissions on the /dev/input/eventXX (whatever the proximity sensor is on your phone). This should be done with a Magisk module or script.@flar2 check below post for proximity sensor fix
I flashed Kirisakura-Kernel Wich gave me a 675 OC function than I flashed Ex. Kernel. The OC function still works and from some bench marks ex runs my FPS best with the mix. The EX app is great to them up to. Only problem I got with it is even if I don't use it and reboot after installing it, it still mods my system on start. I left a pic of backups and it says witch kernel is newer.
