Future compatibility for Custom ROMS with working Indisplay Fingerprint - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

What do you think? Will the indisplay Fingerprint Scanner Work with custom ROMS like Lineage etc. Also Will the pop up camera work?

Some custom ROMs for the OnePlus 6T has the in-display fingerprint working but there is no animation while using it.

You should be rather worried about the front camera motor.

ROMs with almost no bugs

Is there any non OOS based ROM with a perfectly working fingerprint scanner and primary camera. Something that's really stable?
Everything you find in this forum is perfectly stable, maybe with the exception of MIUI.
Oneplus limited custom ROMs by not releasing sources that would make slow motion video, HDR and the "HQ" mode work. This means these are broken on all non OOS based ROMs.
The fingerprint scanner will also get a bit slower, but it's still gonna beat an iPhone.

Would you recommend the jump from oxygen OS at the expense of, what you state to be, worse low light performance, removal of features like slow motion videos and HDR, and the slowing of the fingerprint sensor... I suppose it depends if you use the camera then and enjoy the speed of your phone unlock?

This is totally wrong. MIUI Xs is the only non OOS rom where the camera works perfectly including auto-HDR, Slow Motion and HQ as it is based on H2Os. I am using this build and it even has ota support for miui weekly. Don't flash any other builds like wu or ruy09 etc. Use this build : https://mega.nz/#!H5xEEARQ!jIFx7bad4wBN3s1xXmEd6-8EQGQETMD9_EWsjYWMWSM

Aside from the fact that MIUI doesn't boot on my device, it should be pretty stable. I seriously couldn't care less about the camera as long as it screws my phone up.
I like MIUI. Believe me, I tried. I downloaded every single version I could find, flashed all of them, none of them booted. Flashed fine, but then black screen, white notification LED, computer recognized the phone as Qualcomm debug mode. Yeah...
Works for some, not for me. And I'm not alone with this.

Try this Version. Believe me .... DO a clean flash --> Wipe everything including internal memory and flash from adb sideload.
Make sure your file system is F2FS and not EXT4. Update to latest nougat OOS and then flash as said above !!
If u want I can show my miui by uploading a video to youtube !!

Since we use 7.1.1 blobs from openbeta3 on this unofficial op3t optimized lineage build most camera issue are gone - OnePlusCamera from openbeta3 is included additionally.
Fingerprint sensor was never an issue on these builds.

How did you manage to fix the fingerprint sensor issue? Every other LOS ROM has this issue.....:good:

Sounds strange. Is HDR working? Because I couldn't get it to work even on OOS based ROMs.

Honestly: I don't know. To my own surprise it was just working. The only remaining issue: if you want to add a fp, you need to wait for some seconds before starting to register new fp; otherwise the fps is working as home button.

HDR on back cam is working - no HDR on front cam. What's still missing is raw.
I'm no photographer and I lack a good judgment for stills. I suggest you take a nandroid and check yourself if the rom (especially the cam) matches your demands.

I tried, but just like on OOS based ROMs, I cannot tell the difference between HDR being on or off. That's despite me giving it a challenging lighting situation.
With my Nexus 5, HDR photos had no EXIF info. At least no things such as ISO, exposure time. With the OP3T, I have full EXIF, which shouldn't be possible, because the whole point of HDR is that I don't have a single ISO value and a single exposure time value.
Due to the EXIF situation and the fact that I cannot tell a difference between pictures with HDR on and off, I concluded that it is not working. Am I the only one with this problem?
Can someone upload pictures taken back to back, where one was taken with HDR on and the other with HDR off?

how's the battery life vs oos? and do you have V4a flashed and working?

There's a work around for this. Use on screen nav bar. And then register all your fingerprints. Turn it off afterwards if you don't want.

I think waiting some seconds is the better (aka faster) workaround: changing to onscreen nav bar and reverting back takes about 10ms. Waiting for 5 s takes 5 s... Just a matter of peesonal taste. Work around the workaround...

How does Approach to Peek work in LOS vs Stock

I figure I’ll ask because I have always wanted to know, and this is one of the things that keeps me switching back to stock from LOS.
On stock the approach seems much more sensitive and will trigger in instances where the proximity sensor is not even in play.
When on LOS it seems the only trigger is the proximity sensor.
Just wondering.

Question A fully functional ROM?

Hello,
although the developers are very active and we are getting there, my question is whether there's a ROM that is "complete" at the moment.
With that, I mainly mean the 100% working fingerprint sensor. With that, I mean a ROM that doesn't 100% brightness while using fingerprint reader and that has a functional fingerprint reader when screen is turned off (ie. wakes the phone)?
I am excited about the recent developments, however, I am just looking for a smooth experience for the time being
Thanks again to all the hard working developers.
At the moment, I think the only one that does not light up the screen (not tested by me) is Statix, BUT, apparently the screen needs to be at at least 40% brightness for the fingerprint scanner to work.
You can try all of these and chose the best one for you
(Lineage(18.1/19), OmniRom, StatixOS, ArrowOS (no longer supported, the unit of the maintainer ramdump-ed.))
I haven't tried Statix yet. Good time to try.

Does this mean that fingerprint doesn't wake the phone either?
I currently have Los19, wasn't able to get 18.1 working. Haven't tried OmniRom, but I've tried ArrowOS and it wasn't bad.
Thanks for the pointers! Does anyone know what's the reason everyone is having problems with the scanner?

Question Proximity sensor and face ID at dark problem!?

Hi there! I recently bought Xiaomi 12 Pro Gloabl MIUI 13 and I faced really annoying problem. The proximity sensor does not work and it did not pass the test. Allays shows 5.0 at the test no mater if the sensor is covered or not. And the real problem, the big one is face ID does not work at dark, like there is no IR at all and that is great issue for me, because this makes phone completely useless for me while traveling at night.
What I red the proximity sensor is virtual instead of hardware and it makes problems and user waiting for software solution for years. OK, but what about IR camera for face ID. Is it integrated in this phone or not. I find no answer.
Planning to switch to xiaomi.eu rom hoping for fix, but...lookin for solutions with golobal rom, because I use a lot of banking apps that I`m not sure if they work wit unlocked bootloader.
There is no IR cam, just the regular one.
That's not a 12 Pro only issue, most phones behave the same in the dark.
You can however use the fingerprint, so where's the point of calling the device useless at night?

The point is, when the phone is in holder I just tap on the screen and it unlocks by face ID immediately. That`s I have used with Mi8 till now. Fingerprint of 12 Pro is very slow compare to Mi8 and mostly unlocks with second try.
Well I have to adjust to new lack of hardware, but quite expensive Xiaomi

Try to register your finger a second time as an additional finger. This could help to speed up the recognition.
I faced proximity sensor problems with my 11T Pro but the 12 Pro is working great. I use the fingerprint which for me is lightening fast. Unfortunately without the front IR sensor, no photos going to work like iPhone when it comes to face I'd.

Hi did you try to move the phone towards your hand during the test? because this movement simulates the gesture of answering a call.
Enable double tap to wake, then unlock with index finger
PS Don't use phone while travelling
