Development [ROM][T][OFFICIAL] LineageOS 20 for POCO X3 Pro [vayu/bhima]

[HastaPasta]

Hi. After a recent telegram update the microphone went extremely low almost inaudible.

I played about with James DSP and it worked again.

Telegram got updated again today and same problem except can't fix it this time.

Any ideas or where to ask / look?

Many thanks

My banking app tries to read the device's IMEI, subscriber ID, and ICCID by attempting to open /sys/devices/platform/soc/2c00000.qcom,kgsl-3d0 but that triggers an SELinux rule, which causes the app to fail and shut down:

I don't have this problem on my old LeEco Le Pro3 also running LineageOS 18.1. So I assume there is a difference in the SELinux policy? Would it be possible to fix this?

What is your SafetyNet status ???
If you don't pass SN, no banking app will work !

It's not about SafetyNet - the app (Scotiabank) works fine on my Le Pro3, which is also just running a vanilla, official build of LineageOS 18.1 (no Magisk or anything like that). The issue is the SELinux policy that is causing the error in the logcat messages that I posted. As far as I can tell, the required fix is to update the policy to allow the app permission to read the sysfs entry.

Update: I looked at the SELinux policies from my LeEco Le Pro3 and from my Poco X3 Pro.

When I grep for sysfs_msm_subsys, nothing comes up in the Le Pro3 policies. But in the Poco X3 Pro's policies, there are a few occurrences in /vendor/etc/selinux/vendor_sepolicy.cil.

PS. If you have a few phones you may be interested in testing the app yourself also (you don't need to log in or anything - on first launch it gives a warning about running on an unlocked device, but after that it works normally): https://play.google.com/store/apps/details?id=com.scotiabank.banking&hl=en_CA&gl=US

ok good luck
bye

Thanks, I figured out the problem.

Turns out when I was transferring my settings and reinstalling my apps on the new phone, for some reason Play Store decided to install an old version of the banking app from 2019 (I have a theory about this - looks like the app name changed from com.scotiabank.banking to com.scotiabank.mobile), and Play Store wasn't showing that there was a newer version available.

So I uninstalled the app, reinstalled it again and this time it installed the latest version. The banking app works now. My guess is that the old version of the app was just incompatible with this recent set of SELinux policies.

Oh welp, maybe a workaround on the first page of this thread could solve this issue?

Speaking of gcam... has anyone ever got to have 48 MP working? At least with this one and the suggested configs, it doesn't work for me with LOS.

Thanks in advance for your pointers if so...

it's not a issue for some users... not everyone needs to hide root... and yes.. lineage won't pass safety net (google plays certified device), some banks apps detects the bootloader unlock status.

from what i konw:
1) firmware version is the one you had with stock rom before flashing custom rom. if you don't remember which one you can try "fastboot getvar all" command in fastboot mode.
2) some devs recommend that, indeed, you should update your phone to the latest version.. read op or custom rom's web site to more info.
3) the official miui update guide is good to go < https://c.mi.com/es/miuidownload/detail?guide=2 > double check your device version before proceed. also there are many tutorials in youtube that you can follow to update or restore to stock rom

But i don't want to restore MIUI, i want to update to LineageOS.
Maybe are you saying that i have to install MIUI before install LineageOS?

yes, in order to have your device updated with the last firmware, you'll need to flash the lastest stock rom and then flash lineage os.
well.. that's is how i do it.

You don't have to, if you have TWRP or adb you can flash the firmware-only zip and update your firmware with that.

As for checking firmware version: check your baseband version and compare to this.

Hi there,
I need some help. I installed lineageos 18.1 on my poco x3 pro and I noticed that the phone is not vibrating. It did before and still does as a conformation when shut down. But no message or call or feedback while typing is working. I switched on every "vibrate" I could find and switched off every energy saving and do not disturb. Does anybody got a hint what I can do? Thank you very much

Hi. Push volume up and an oblong volume scale shows on the screen with a small square with an icon in it directly above. Tap the square to switch to vibrate
