You are taking this optimization way too serious. That five days you put into tweaking your kernel outdoes the few milliseconds you accumulate over time ;-P

Its all pretty smooth (i.e. smooth enough) for me. Smoother than MIUI in my opinion. FOD is usually rather fast, but occasionally needs several attempts. I blame it on the screen protector.

Just installed it and it's almost a blast. But I found two things I don't like:

- Fast charging is not working. Is there any way to activate it? Or is this kernel related?

- How to turn off camera sound when Face unlock?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] epraes:
I found a bug I think it's related to this ROM, as I come from official MIUI and it didn't happen then. I use Google Duo for videoconferencing and the microphone doesn't work in group calls. It happens only on Duo and only with group calls. Individual calls work fine. It seems likely it's an app bug, but the fact it works differently on official MIUI and PE+ makes me think it could also be ROM-related.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Belyna:
Hei

1 - fast charge is working check your charger

2- go to setings- system - and disable camera sound

But in the past I charged my phone with my PC Monitor via USB every night. It has a high power USB port. Fast charging worked fine on MIUI before. On PE it's only slow charging. I tried charging with Xiaomi charger via wall plug and fast charging works. That's the only thing I'm missing. So I guess there it's not possible :crying:. But maybe I coud try a different kernel? Any suggestions here?

And another strange thing: If I unlock the phone it's always flickering for a short time. I'm coming from latest MIUI v11.0.5.0 so my vendor should be OK I guess.

Also, with the 9 Lite, flashing any forced encryption disabler results in not being able to set a PIN and fingerprints, whether it's in xiaomi.eu or AOSP ROMs. Is that the case with the 9T?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] xfighter11:
Solved my charging problem with Hasty Kernel which works very good. Is there a way on PE+ to change position of lockscreen notifications? They are very central below the clock but I like thos a little higher.

/EDiT: BTW on youtube videos there is a setting tab called "The Pixelizer" where you can modify a lot more. But I don't have that one in my PE+ edition. Any advice how to get that?

I recently read on the Lineage OS post that Android Auto doesn't charge the phone while using it, this is a behavior that I've been noticing on this ROM for a while and today I managed to take a screenshot of ampere while the phone was connected to the car and using Android Auto, here is the result:

I also noticed that in lockscreen the phone shows "Charging slowly"

Tomorrow I'll try another USB cable but I think it's a software side bug because on my old OnePlus 3 the phone always reach 100% battery while connected to the same car and the same cableView attachment 5011299

Hi, try AccuBattery, you'll see the exact charging rate. After like 10 seconds the charge rates drops from around 1000ma to -600ma

It's the average discharge rate with AA running on the car and phone screen on. Basically the system still think the battery is charging but in fact it's not. I have the issue on LOS and Havoc, no matter what cable I use.

Today i revert back to MIUI to try I'll let you know when i try tomorrow.

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] GabiML:
No bricked phone in that case. Look, install correctly adb drivers and google ones or drivers for phone, make sure you update everything. The download fastboot latest miui 11 from any site. Not recovery, fastboot! The extract zip file in adb folder and run flash_all.bat. ALSO make sure yout device is unlocked. Please notice that when you flash recovery and wipe system it work only once till you flash another system. If you wipe and reboot to recovery only fastboot will work. Hope to solve the problem!

Hi,

I love this rom, been using it since January 2020 and it has improved quite a bit along the way.

There is one issue left for me with the fingerprint reader.

During the day, it works 100%.

Then when the sun goes down and night mode activates, it stops working. I assume this has something to do with it reading better when night mode is off. However I absolutely need night mode, so for now at night I have to use pattern or pin to unlock and log in to apps.

Is this a known issue that will be looked at?

Many thanks in advance.

Does anyone know the name of the Magisk module that apparently allows us to unlock using the FP sensor without first turning on the display?

Are most people simply double-tapping before using the FP sensor?

I've been using my Mi Band 4 with smart unlock, which enables me to double-tap and be taken to my home screen. However, when I turn off my display by pressing the home button from the home screen (a gesture I configured in Nova launcher), smart unlock doesn't work (it asks for the FP). However, if I turn off the display with the power button, it works. Weird!

Hello developers, [MENTION=8801146]baalajimaestro[/MENTION], [MENTION=9050662]Ray_lau[/MENTION]

I tested May update on vendor 11.0.5.0 partition. After flashed ROM, it stucked at fastboot, I flashed Hasty Kernel and solved this issue.

I will edit this post if i find any bug.

1) I have to turn off front camera effect and sounds again and again when i restart device.

2) For some reason the temperature on the lock screen is in Fahrenheit. Is there any way to change it to Celsius and set my location? I've looked all over in the settings but couldn't find anything.

3) I have to turn off "usb-debugging feature" in "developer settings" again and again when i restart device.

4) AOD clock does not move on lock screen to prevent screen burning. Brightness is high.

5) FOD is working but sometimes it is not fast. While night light is on, it is getting harder to use FOD. Doesnt recognize my fingers quickly.

6) What is the version of GCAM7 that you used in PE plus? I would like to download/install it manually in PE.

7) Except the topic, I have a VPN program with network based integrated ad block feature but eventhough it is turned on, i cannot still bypass Google in-app adds. (For example in-app adds in Duolingo or Drops lang apps, ads on Chrome browser at some websites) Anyone knows why? How is designed Ads system on Android 10? Which process or task are responsible for this? I am trying to understand design.

8) Feature Request: Is it possible to isolate and adjust sound volumes dynamically per each app in Android 10? For example while studying/listen lesson in high volume, i dont want Spotify stops in background in low volume.

Thanks for your effort. Well done. I really appreciate.

I want to donate you but Paypal is not allowed in Turkey. Is there any alternative way?

Thanks
