Lockscreen anomalies - OnePlus 6T Questions & Answers

I'm not sure if i'm posting this in the right place but couldn't find any other more appropriate location. I'm running Oxygen 9.0 build A6013_34_181001 and I've already noticed a few bugs.
I have my phone set to use fingerprint unlock and pattern unlock. Pattern lock is configured such that the pattern line is NOT displayed when I enter it. This works fine, except after a reboot. Upon rebooting the phone I'm prompted for my pattern unlock, and the pattern is displayed when I enter it. After this one instance, the pattern display is correct and consistent with my setting. Subsequent pattern inputs don't display the line, it's just the first one after boot.
I also noticed a strange issue with the fingerprint unlock. When the screen is off and I double tap to turn on the ambient display, normally I put my finger on the fingerprint sensor and the display brightness increases. I'm assuming this is to provide illumination for the fingerprint sensor to function and get a good image of the fingerprint. Sometimes when I put my finger over the sensor the screen doesn't brighten, and the sensor can't read my fingerprint. I know it's detecting my fingerprint and trying to read it since I get the animation on the display around the sensor, the screen just doesn't brighten and the sensor can't read my fingerprint.
There have also been some instances where the double tap on the screen doesn't turn the ambient display on. I can use the power button to wake the phone, and that works fine, but periodically the double tap just won't turn the ambient display on. I like this feature so I can quickly check if there are any pending notifications without having to press any buttons, most often when my phone is lying on my desk.
I haven't been on any of the OnePlus forums yet. Do they have a forum for bug submittals?

[Q] ambient display usually unlock the phone

I got the ambient display on my S5 (G900F) form CM 12.1. Thanks to the gestures control, when I wave my hand it will display time, and the screen will light up. It's really cool, but it's easy to unlock the phone by mistake when the phone is in my pocket, because the proximity sensor detected a "hand wave". Once the ambient display is on, the phone just needs one swipe to unlock the phone.
I think the screen should keep locked even I tap the screen when it is on ambient display mode. Is there any way to achieve this function?
Sorry for my poor English

TWEAK/TIP - Prevent accidental unlocks

One of the big issues I have found, mainly with CM based ROMS, is that the option to prevent accidental unlocking seems to be missing/unavailable.
I've been testing various apps and utilities that monitor the proximity sensor, but there is one big issue - they monitor for screen on, but it seems in CM12.1 that the monitoring app doesn't work or get a screen on signal when you're using a lockscreen.
So the solution is not to check for screen on, but check for screen unlock.
I have a TASKER profile set up as follows:
If screen unlocked and proximity sensor on, then turn the screen off.
Works really simply. cover the proximity sensor with a bit of cloth or something and test it - if you double-tap the screen on, or it wakes due to a notification, the screen still goes on. But any subsequent action, eg slide to unlock or click on a notification, triggers the screen unlock flag, and this then checks to see if the proximity sensor is covered, and if it does, it turns the screen off again.
I CAN POST SCREENSHOTS IF ANYONE WANTS FURTHER INFO - BUT I'D SUGGEST GIVING TASKER A GO AND A PLAY ANYWAY, IT'S A BRILLIANT APP.

Screen Dimming

LG K20 Plus boots up then screen dims about every 5 seconds. Had to find an app to keep the screen on. Went to settings/display and tried various settings but non would work to keep the screen on for any designated time adjustment. Any suggestions? Also, other issue; after setting up the fingerprint security, that doesn't work Phone boots up and on screen says fingerprint not working put in your pin which does work.

AOD Fingerprint Sensor Guide Image

Anyone know of a way to get the Always On Display to show the sensor area for the fingerprint sensor all the time? (The little white fingerprint icon) This should absolutely be part of the AOD, instead of just a black area where you guess your way to the fingerprint sensor.
It would be super helpful to be able to actually see where to place my finger without pressing the lock button, tapping the black space on the display, or doing the lift to wake.
Are there any custom AODs that have this?
my guess is if you leave FP icon AOD it would burn in over time, so it's not very good idea..

Click to expand...
Click to collapse
What if the image of the fingerprint image changed shapes every hour or something? Like, alternating curves?

Ambient strobe like display issue

Hi,
since 2 months ago, i meet an issue which is kind of boring.
I have the ambiant display with the tap to wake mode ON and the fingerprint sensor activated.
At the begenning of my use, i have not met any issue : ambiant display was functional (i.e written informations on a black screen).
Now, when i wake up the screen with a double tap to wake gesture , informations are stile written but, this time, on a grey flickering/flashing screen (kind of stobe ligh effect). At the moment i touch the fingerprint sensor, it stops to be flashing grey and return to normal black.
Does someone have any idea of this issue? I am hesitating to proceed to a factory reset in order to see if it solves it.
Thanks in advance for your comments.
