UI freezes LinageOS 15.1 - Xiaomi Redmi Note 4 Questions & Answers

Hi, I am using latest nighty build on my xiaomi redmi note 4x (mido) and UI freezes randomly. Affects any apps, launchers etc. Only unfroze part is notification panel and power menu. UI unfreezes after random time or after restart of the device. Also I just found that UI unfreezes after clicking on any notification.
I think this might be the source of the issue (logcat):
Code:
08-05 19:26:17.988 E/Surface (14617): dequeueBuffer failed (No such device)
08-05 19:26:17.989 E/ViewRootImpl[Toast](14617): Could not lock surface
08-05 19:26:17.989 E/ViewRootImpl[Toast](14617): java.lang.IllegalArgumentException
.......
Maybe someone has any ideas how could i find the cause of this issue? Thank you in advance.

I have tried to unlock the device because I have received this advice from seller. But the issue is still present. Maybe someone has any ideas regarding the errors? What could be the cause?

[Q] Restart Problem

Is there anyone with a solution to the random reboot problem of Moto E?
i have faced these reboots on the stock room,Paranoid Android as well as CM 11.
I don't think it's a Rom issue, it's either a hardware issue or a driver issue maybe.
Is there any one who can look into this and help me out with a proper solution to this?
Note : The random reboots mostly occur when i am trying to unlock my device pressing the power button, i have faced a few random reboots while trying to switch apps too.

lockscreen delay in all roms

Hello, after I installed a miui 10 Nougat (I can not remember which one) a bug appeared. Every rom I install now gets delayed on the lockscreen when notification arrives. When I press the power button, it takes about 3 seconds to light. I've tried installing a lot of firmware, roms, etc. Only in the Oreo roms does the apparent bug disappear. Anyone know what it can be and how to solve it?
Thanks.
Try to install Miui 9 stable with Fastboot (not recovery).

Methods to find out crash reasons

Hello,
on my Ray Adrian's 'lineage-14.1-20170514-UNOFFICIAL-LegacyXperia-urushi.zip' ROM runs not that stable.
In a time frame of about 5 to 8 hours there always is a sudden crash even when you don't touch the phone. It restarts after the crash automatically.
My question:
How can I find the log files and what else can I do to find out the reason for this crash?
Or did you make the same experiences with this version cm14 so that I have to accept it to be 'normal'?
I have GAPPS installed as well.
I presently assume that it should be caused by any background service of my ~35 downloaded apps...
Thank you for your help.

Leagoo Power 5 not having Fingerprint Options in settings

Hello,
It's been 2 weeks I am trying to make the fingerprint options show on my Leagoo Power 5, that has a 6763V SOC.
It happened after I installed TWRP and formatted the data the first time. After that, I have reinstalled both stock firmware that exist for this device, but no chance to see this feature. I formatted it and did that more than 20 times.
I even installed other firmware like AOSP, AEX, Havok OS, Lineage OS 16, but no one of all these was able to see the fingerprint settings inside Android (not existing).
I noticed that another user of Leagoo Power 2 has opened a thread in another forum, and he has the same issue.
Could it be that there is a fingerprint partition hidden in the system, that might deleted or corrupted, or something like that?
I tried to use logcat, while touching the fingerprint and I get several errors, which means the hardware is working, but it must be a software issue.
I have attached the output of the logcat file, where it shows HAL issues.
Would appreciate if anybody has any idea how to solve this.
PS: Where can I add this device to XDA, and contribute with formwares that work with it, TWRP, boot unlocking and common issues, solutions ?

does custom os fix random reboot during call issue on redmi note 9 pro

hi
my friend own redmi note 9 pro
and have 'known' issue of random phone reboots during calls - like at least once a week during call his phone reboots itself
it was send to 'warranty' repair 3 times ! but they did not fixed anything.
so my question is
IS THERE ANY CHANCE THAT CUSTOM OS WILL SOLVE THIS ISSUE? lineageos for example?
or does anyone had this kind of issue with his one and custom os was the solution ?
thanks and regards !
It happened to me that my RN9P joyeuse restarted several times during a phone call or just while using it. The problem was fixed for me during the update (I think miui 12.5). It was probably a software bug when the phone tried to switch between LTE and another network which caused a restart. I am currently using the ForkLineageOS custom rom on android 12 and there are no reboot issues, previously i used lineageOS and pixel experience on android 11 and there were no problems either.

Can you review lineageOS for me?, is it good?, stable, and how to install it
not on rn9pro but on my redmi 9 everytime I try to call "*143#" my phone just magically reboots, and also the reboot persists too when I try to maxxed out the volume.
