[FIX] GSI In-Screen Fingerprint Sensor not working - Treble-Enabled Device Guides, News, & Discussion

Here's a little guide if your in-screen fingerprint sensor won't work properly!
In my case, this happened on Pixel Experience Android 12.1 on a Samsung A52s 5G. The solution isn't anywhere (I don't think) to be seen, so I hope this is of great use!
1. Go to 'Phh Treble settings'
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2. Go to 'Misc Features' and find 'Under-display fp color' (Near the bottom of the 'Other' category)
3. Set it to what the default colour was on the stock ROM (for me, this was white.) The options are Green/Cyan/White
4. Go back to fingerprint settings and delete them all, then reregister them.
5. Try and unlock your phone with it. It should work!
Samsung
If it still isn't working on Samsung, you can try enabling 'Enable workaround for broken fingerprint sensor' in 'Phh Treble Settings', 'Samsung features', 'Workarounds'
Hopefully this helps somebody out! I spent like a month trying to get it working and finally this fixed it. Seems a bit weird how the colour of the scanner breaks it, but hey, if it ain't broke, don't fix it!

UPDATE PhotoSphere works after clearing data (One does not have a gyroscope?)

UPDATE!! PhotoShpere is working after install if you delete data from apps menu and reboot! Still not sure on why the Gyroscope is not showing up on Sensor Kinetics. BUT IT WORKS!
Admin, could you change the title of the post? Thanks
Steps to get working
Swipe down from top right of phone
Click Settings
Scroll down and click Apps
Find Camera and click it.
Click Clear data
Reboot
Once the phone has restarted relaunch Camera and swipe from the right. PhotoSphere is there now.
----------
Tested Google Camera and discovered the photo sphere feature is missing. Did some digging and it turns out Google Camera use the gyroscope for this feature and possibly the pano feature as well.
I checked the sensors and we are indeed missing a gyroscope.

This does not mean the One is a terrible phone. It simply means this is one area that was more than likely left out to help keep price down.
I will update as I find more information.

If anyone can shed some light on this. Does it have one and its not being picked up or is it simply missing and using some other method?
Thanks
Wow I can't believe that this would miss. Got the Moto G without gyroscope and sometimes I missed that feature so my next phone should have that. Can you please ask about it in the OPO forum? I would love to know this now.

gsm arena has listed it here
Thanks I'm Sputnik24 from the OP-Forum
Unfortunately, the features can be gone after a next reboot, so you have to do this again. Quite annoying, but a software issue. So there should be a bug fix.
It does have a gyroscope according to cpu-z

That's strange. Although, on this page, it shows that OPO does have a gyroscope. http://oneplus.net/one#specifications

There was some debate on this in the OP forums...
A detailed view indicates there is a 'Gravity' sensor and a Geomagnetic Rotation Vector. Basically, Gravity sensor tells it where down is and the other one gives info on any offset motion from 'down'. So it essentially knows any position it is in, making it a gyro. I think the function is there but they're pulling data from 2 different sensors and neither reports it is a gyroscope. Just guessing here...
Install the latest update OTA and the gyroscope is visible also the Google camera photosphere option is working now.

[PROBLEM] proximity sensor isn't working anymore!

Hi all
I'm on tw lollipop with root permissions and since some days my proximity sensor isn't working!
On call when I put my phone near my ear the screen won't turn off, but for example if I use air gestures for skipping tracks on music player it works. Trying a tester found on the play store, the proximity sensor is still far even if I put my finger on it. Dialing *#0*# shows me this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Consider that numbers in ADC (idk what they are) increase to from ~100 to 1000 when I get close with the finger
Someone can please help me solving this? Thanks
lolipop is trash.
get back on kitkat :good:and no probs for you!!
I'm on CM12. Proximity sensor does work. 8cm uncovered. 0cm covered. Tested with sensor sense app. While I was on KK I calibrated it with some ADB commands I googled. Before the calibration it never was 'uncovered' (after callling I could not hang up, because screen remained dark). Always these problems with sensors....
Proximity sensor, GPS sensor and compass sensor is s**t on note 3.
Hi all.
Just solved using terminal thanks to a xda user. Now it perfectly works, please close the thread
Regards
Can you please share what you did to fix the proximity sensor. I seem to have the same problem after upgrading to TW Lolipop. Thanks
@Link23 i just followed this guide. Hope it helps.

[TIP] Enable Hidden Reading Mode in OnePlus 3/3T

Hi everyone!
I've found that the OnePlus 5's "Reading Mode", which has been exclusive to the OP5 from the start, has been integrated in the latest OOS 5.0 Update for the OnePlus 3/3T but is still hidden, as expected so that this can remain an exclusive to the OP5/5T

Here's how to access the hidden settings:-
I used Nova Launcher Prime for doing this.
1. Add a Nova Launcher Activity by going into widgets.
2. Scroll down to Settings & then find "Reading Mode" & select that.
Now by clicking on that created Activity, you can access the hidden Reading Mode settings

This is great! And OnePlus said that this feature won't make it to OP3/3T via a SW update because of hardware shortcomings. I'm not sure why would they do this..

Yes they did I believe they added this mode by mistake in the OOS build for the 3/3T. I wish the new 5T's Face Unlock implementation also arrives for our 3/3T

Thanks!! Awesome work. :good::good:
This doesn't really work as it should.
We lack a hardware sensor, RGB ambient light sensor.
So what we get is basically Night mode with the Monochromatic profile.
The real deal should adapt the color of the display to the color temperature of the surroundings.
This was already possible to achieve without this entry, by enabling both the features I mentioned.
But congrats on the find. :good:
OOS ROMs are getting as stuffed as a turkey on Thanksgiving.
Thats a great find bro. Thanks for sharing
Didn't work for me.
Whenever I switch in reading mode. It goes grey for 1 second and then back to normal! Any solution?

Camera starts to blurr on increasing distance after 30cm from object

Untill i was using MIUI everything was fine but after I flashed lineage OS 14.1 camera quality is decreased but still it was fine. Then i tried different gcam mods and flashed a couple of zip files in hope that camera will became better but it's quality is totally low now. Even i reverted back to MIUI to see if that fix the issue but still its persisting. I have tried Miui Stock Camera, Bacon Camera, Open Camera all having the same issue.
About Issue : On taking a picture from distance it becomes blurry the more I increase distance more it will become blurry. Picture starts to blurr after moving the camera away more than 30cm (i know it's hard to believe)
Check the screen shots and plzzz help me...
(good in this)

I think, thats your camera problem Not the rom / apps problem.
Yes your camera isnt using focus just flash some zip files for focus and it will work again thats the cameras focus problem
It happened with me, i had to disassemble my mobile and adjust camera module a bit to get the focus right.
Follow this guide on https://www.youtube.com/watch?v=pcLhQtdzY4A, its not for our device but you can have a loot at it for a reference.

Most stable up-to-date ROM for h870

Hi volks,
I tried some roms since my warranty period is over.
But I can't find any 100% satisfying right now.
Hevoc was a desaster, lineageos proved better, but there was no fingerprint sensor and huge bettery drain, which is critical for me. The most fitting so far is Pixel experience. But this ROM does not support instant tourch with long pressed powerbutton, which is very useful for me and USB connection to the computer seems corrupt.
So what ROM do you suggest?

Hi @iCuba, the issue answering your question is and will always be highly biased due to individual experiences. That said, my suggestion is to stay on LineageOS 14.1, that's what I use since long time. I do tried version 15 and 16 but I had a couple of issues that were show stoppers: camera not working and too many random reboots.
Tha bad news is that the ROM is not being maintained anymore in XDA, see this thread.
The good news is that you can compile it by yourself and that security patches are still backported, so you will have a certain degree of extra security.
As per my experience, note that I don't use Google Apps in my phone, and I use the phone very seldom. I install a few apps with f-droid and self-host all my services. Also, the fingerprint sensor works, and I have no battery drain at all, check these screenshots, 4 days is very very good for me.

Hi knzor,
thank you very much for your time to create this detailed review of your personal experience with Lineage14.
Since no ROM fitts completely to my needs until now perhaps I will give it a try at the weekend. I hope it is not that difficult to compile my own version of lineage. I lost my interest in computers a few years ago, since one problem creates a nother and updates seems to make things more worse than bevor.
