No, you have to activate AOD to be able to unlock with FP. Btw it works very good and does not have many impact in battery

Hi. I would want to ask about ANT+ support on HavocOS.

I installed Havoc over Miui 11 EU stock (11.0.2.0.PFJEUXM) so I think I had latest firmware.

I've tried with this Havoc last build but no luck.

ANT+ Radio Service doesn't ask permission to use ANT+ Hardware so I cannot allow it, therefore it doesn't works.

ANT+ can be tested with the app ANTtester from Quantrity in Playstore.

It allows you to install required app's and allow "ANT Radio Service" acces to "ANT hardware".

Please fix the in screen fingerprint censor and the ambient display which is always at the same brightness and position. The ambient display in general is pretty bad if I'm being honest. even the fingerprint censor doesn't match the one on the lock screen, this isn't polished at all and worse than the xiaomi 11 rom, Why release then? I don't get it.. by the way I don't know if it's pressure sensitivity but the full screen gestures are pretty inaccurate and also there isn't even a dark theme dialer app

Experiencing the same here, recording the FP in the settings menu works fine. But once at the lock it doesn't unlock at all.

Tried with 3 different fingers, registering them, deleting them, registering them again, deleting once more. Couldn't unlock my phone once with the FP scanner. :(

Sadly, this version doesn't work aswell. It crashes at start up. Checked and set permissions before starting, doesn't help.

Maybe something wrong in my installation since FP does not work also? Any tips? Maybe new install, or wipe cache or something? :confused:

Having some trouble with this ROM when installed.

The latest version in this topic, doesn't let me unlock my phone with the FP. Registering fingers works fine, but once at the lock screen it doesn't recognize any of my fingers.

Registered and deleted them several time+reboot, but sadly I can't get it to work...

Same goes for a working Gcam, tried varies versions, but they all crash @ start up.

Then I clean installed the latest version available in the Telegram group, that has the same issues with the FP scanner.

Does work in Security settings when registering, but does not work once you want to unlock your phone.

Deleting and registering+reboot and such to no avail...

Aside from that, when fresh installed it won't let me search in settings, cause then it gives me an instant error that (stock) camera has stopped working.

Tried dirty flashing, clean install. Nothing works, keep getting the exact same problems every time.

Anyone else? Or am I just doing something very stupid? :confused:

For me the front camera works perfectly. It did get stuck once and I had to use an APK I found to unstuck it.

The problem I'm having with this ROM is that the right audio channel is silent. I'm not 100% sure this is ROM related, but for sure both channels worked when I was using the stock ROM, and as this only has one speaker it can't be a hardware issue. Anyone else facing this?

As for the mono/stereo problem, I'd appreciate it if someone could test both channels on the speaker. I'm pretty sure this is Havoc OS related.

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] lazyaf01:
Hi there. The developers are aware of the speaker bug. Unfortunately fixing it breaks other things such as audio in video calling. Afaik it is due to broken sources released by xiaomi. To compensate for that you can enable mono audio in accessibility settings when using speakers and disable it when on earphones.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Schnedi:
You have different options:

1- An application that let you uninstall system apps

2- Magisk and module Debloater

3- File explorer with root access

My favorite

4- TWRP (navigate to the unwanted app and delete it)

Hello mates.

Can someone give their opinion on the battery life on the last update? And if possible also a global opinion?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] epraes:
Battery life is excellent, far better than MIUI.

Apart from that, this is a very smooth, stable and customizable ROM. I've been using the latest version for a week without any issue. Fingerprint reader works fast and reliably, better than on MIUI, at least for me.

The only glitch I found is the speaker, which produces audio that comes only from the left channel, but I installed a magisk module and it was solved. D2TW can also be activated with a module.

So far so good. Kudos to the developer team for their excellent work.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] isman77:

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] epraes:

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] dusan92:
I flashed and used this ROM for a couple of days and went back to MIUI. Here are my conclusions:

I really like how much the Havoc improved since the days I used it on my old whyred, it reminded me why it is my favorite custom ROM. It's very smooth, clean with not a lot of bloatware but with tons of customisations. It was fluid all the time, even gestures worked great for me for the first time. there were a couple of hickups and app crashings but nothing annoying. The front camera quality is as same as in MIUI during video calls, which wasn't a case with my old Whyred.

My problems with it: the inability to disable the fingerprint icon while the always on display is turned on. Maybe it's only me, maybe only I can't find the option and I'm afraid it'll burn in.. Also, flip the phone to show the always on/turn on the screen doesn't work properly. Fingerprint sensor works okay, but not very reliably. Sometimes it won't unlock no matter what.

Otherwise, it's a great ROM, I hope these will be fixed in 10 version. Thumbs up for the developer, thank you so much, this is the best custom rom for this phone as of now.

Thanks for your feedback guys, and to everyone else of course! But these two stood out to me because they used the last version of Android 9 and it made me want to ask something.

What firmware did you both come from? While you're at it maybe tell us what TWRP you used or anything else you think would prove useful. Maybe it's better to come from MIUI 10 rather than MIUI 11 or something.

I'm still on stock and am enjoying it, if this indeed gives better battery life than stock MIUI 10.3.15 then that would be great, but for now life is a bit too busy to "experiment" (I'm sure it will be great experience) so will hold back for a while. In the meanwhile, what TWRP is the best for backing up and restoring a nandroid backup? Unless there's a better way to do so (MiFlash?)

Much appreciated.

Hi there.

I went to Havoc from the recommended V10.3.11.0 firmware (I downgraded my MIUI11 install using MiFlash first to V10.3.11.0 and then followed the instructions in the first post). I don't know if it makes a difference or not.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] dusan92:
I came from Xiaomi.eu stable MIUI 11, it's Pie to begin with. Regarding battery life, I would say that Havoc is a bit better than MIUI 11, but I'm sure with a bit of customisations and fiddling with it can be better for sure, at least 1h SOT over MIUI 11. 10.3.15.0 was worse than both of these for me.
