Does anyone have the same charging problem on the 0411 version?

Insert the charging cable, the mobile phone does not respond (smart charging is off). replace the charger and the cable still the same. turn off the phone, still not charging, after reboot three or four times. it finally works.

And in response to such problems, how to capture logcat?

Syberia Os 3.6 issues

Hi! The Rom is awesome, but there are two issues/bugs:

1. "Double tap to wake up" doesn't work properly;

2. Night light collapses when DC Dimming is on and the auto brightness works during light changes.

I hope that you can fix this bugs in the next release, hovever I still use this rom because very stable and very performable. I love it.

Thank you very much for your work. Goodbye.

Switched to that nice ROM from MIUI one month ago with a clean wipe, also updated to the last OTA.

Any idea why I've got a terrible battery life (SOT of about 6H compared to 12H on MIUI) and why the phone is heating a lot with light usage (CPU goes up to 55°C while just doing web browsing with Chrome in 4G+) ?

I don't seem to have any app consuming anormal proportion of battery in the battery stats.

This Rom is almost perfect. I like the possibility to change the vibration haptic. Also this is the only Rom, where I can change the system font over all Screens and Bars. The only Thing is the huge Battery Drain, 10 Percent over Night and 7 to 10 Percent over 3 Hours in Pocket. Clean install without Gapps with Magisk and MicroG.

If this is fixed it will be my daily Driver! Thank You

Is it normal?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] I-Immortal:
I have the same battery and temperature issues:

I barely reach 6h SOT now (whereas I had 12h on MIUI/xiaomi.eu) and the phone's heating without any reason. Sometimes (well most of the time actually), when I'm taking the phone out of my pocket it's hot (40~45°C) and has lost several battery percents.

Google Play Services and Android OS always have the highest battery consumption in the battery stats. I installed 22/04 nano GApps with a cache wipe yesterday, might as well try a clean flash to see if it gets better.

Otherwise a really great ROM!
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Seki_:
Oh, I also wanted to do that, but didn't have time. Can you report if the battery problems persist after clean flashing?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] infoflo:
Love this ROM but I got a problem with roaming. Roaming won't work on one of my sim Cards (O2 from Germany, can't get roaming anywhere in the EU).
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Zen920:
Not OP but I clean Flashed latest ROM with MicroG and I still get this 6/5 average SoT, this is mostly using browser(Kiwi), Vanced and some Twitch.

Pretty sure before the switch to OSS I could get up to 11h SoT if I remember correctly.

This seems to be the case with other OSS Roms too in my experience.

About the temperature, aside from rare cases (slept with twitch on), I've never got more than 36°~, on light usage I sit mostly to 28°~.

A note, I'm using Englezos Kernel which should be more towards the battery usage rather than performance (GeekBench 5 is SC =705 and MC=2480, with Immensity I get roughly 10~more).

The main benefit is the discharge rate at night which is 2/3% every 8h. SoT is slightly better but not even close to old Syberia versions, still worth a shot if you don't care about performance (gaming) and want some more battery . I dirty flashed it over Immensity via TWRP, take a backup of the boot.img just to be safe.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Seki_:
Thanks a bunch for the heads up. You just saved me a lot of time. I think I'm just going to flash the latest version before the switch to OSS. The battery life was just awesome.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] I-Immortal:
Well after a clean flash with lastest update + magisk + openGapps the SOT is still quite bad (6h, compared to MIUI it's half the SOT for about the same usage). The CPU (and phone) tends to heat quite a lot even with light usage and even more with -light- games (Clash Royale), LTE browsing, or while charging. The CPU temp sits between 40°C and 50°C nearly all the time.

As great as this ROM features are, I need something else as I don't want to wear out my battery and hardware too quickly with this new phone. Even though I can live with the low the battery life right now since I'm quarantined at home, I'll need something more durable when on the go. Good luck with the development of this ROM, I'll definitely try it again when it's all improved :)
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] nonewithnothing:
0419 version

After using this for some time, I guess many problems should be caused by the Vulcan HWUI renderer.

The phone gets very hot when watching videos and the battery draining too fast, and some Apps cannot be used normally (the screen becomes blurred and indistinct, full white or other, etc), But there was no such problem in previous versions.

I changed the render to opengl yesterday, these problems seem to be solved.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] NATO66613:

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] LionHeart90:
HDR and pop camera are totally fixed now (almost for me), I still not had the opportunity to try everything well, but I just recharged the battery after flashing the rom, and still while charging the temperature rises a lot. At the end of the recharge it settles down. It only happens with Syberia. Idk why. However, in my opinion, it remains the best ROM with OSS vendor:good:
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] chcwong:
Thanks for update, and I have updated by system update. I would like to share my finding as below.

I found pop up camera cause force close to GCam v1.7 by Urnyx, but it is working fine with ANX Camera v180. On the other hands, portrait mode is working on GCam v1.7, but cause force close to ANX camera v180.

I would have more trials and share my finding.

further trials found GCam v1.7 calls some functions when switching to pop up camera in normal shooting model, which cause force close. Meanwhile it is fine if I switch to pop up camera in portrait mode.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Seki_:
