Keyboard backlight problem

Hi!
When I slide the keyboard out and start typing, keyboard backlight sometimes doesn't switch on. Its annoying when I use the keyboard in the night.
Anyone has the same problem / or know how to solve this? Thanks.
I have same problem!
just turn off automatic backlight in settings..
Weird
Sometimes for me it doesn't come on immediately, but after the first key press it always comes on.
How annoying.
Although, are you typing in half light? I tend to be typing in bright light or pitch black, never half light that would mean it'd affect the backlight but i couldn't see the thing unlit.

Backlight for touch-keys

Does anyone know how backlight is suppose to work for Home, Menu, Back and Search keys? Is it suppose to stay on as long as the screen backlight stays on or is it certain amount of time? What triggers them to come on- key press, screen touch, trackpad touch or all of the above? Mine don't seem to follow any rhyme or reason, at least I couldn't trace a pattern. I know that I was messing around with the phone last night in the dark and they would come on and go off as they pleased. Does light sensor have anything to do with it? Please sound off your findings and ideas.
Thanks!
Mine don't seem to follow any rhyme or reason either - it's a bit maddening. And the same goes for the backlight of the physical keyboard (sometimes it comes on, sometimes it doesn't - no telling why), and also the automatic adjustment of brightness (i use the phone for a minute and suddenly it gets super-bright).
Hopefully these are all just bugs that will be fixed with an OTA update, but it is weird and I'm glad to know it's not just my unit since I don't want to replace it (I got a solid hinge - good stuff!).
I think I figured it out. Backlight for touch keys is controlled by light sensor and also has a timer (few seconds), so if it's bright enough outside - they will not even come on. If it's dark - they come on and stay on for certain time then go off untill you press one of them again.
Now, the other thing that I'm noticing is that my haptic feedback is not working when pressing one of those buttons or long-pressing the screen. Anyone else has that problem?
I have used my phone primarily in the dark. All my lights are always on (when the screen is) and the auto-brightness is too bright. If I turn brightness to minimum, the always on lights are way too bright compared to the screen. I really wish the designers had tried to use this phone in the dark (laying in bed) and realized the auto-brightness and lights are too bright in pitch-dark!
Also I am getting real sick of rotation. On my G1 I could disable it completely unless the keyboard was out. I like to lay in bed or on a couch and use my phone sideways, but not rotated. This seems impossible to do on the G2. Disabling rotation doesn't do anything for 3rd party apps or even GMail for that matter. For some reason this was not the case on the G1.
It will be hard to go back to the G1's one-second+ lag after every press and the incredibly slow loading webpages now that I have experienced the G2, but there are too many really annoying problems, so I think it is getting sent back.
if you have your backlight set to automatic... it will cut on only if the room is dark... check your backlight settings
It's an issue with the way android uses the light sensor. It's very poorly coded.

Display issue

It adds greyish tint to blue and black colors. This happens when night clock is on, sometimes randomly. Sliding brightness levels seems to fix this. Anyone having the same issue?
Pictures on this thread (it was not made by me but it shows the issue very accurately).
Edit: now by phone seems to freak out. When i slide down notification the phone turns to bright green. Turning the phone off and on fix it, but it is such an expensive phone with such issues... so dissapointed.
No?
No problem here

Essential phone jittering when turning of screen

Is anyone else noticing the screen jitter redish colors when turning of the screen? It only happens here and their but it's really annoying. It started happening after the 8.1 update

screen stays awake after some notifications come in

Happened on my 7pro now on my 8pro sometimes just randomly stays awake after clearing a notification does this happen for anyone else?
Hey.
I hear it for the first time. I have never encountered this before
Hey, I was just about to post the same issue - my screen tends to stay on randomly too. No idea what the root cause is but am hoping that others have encountered it. If we can figure out a reproducible scenario we should be able to log a defect with OnePlus.
Noticed my lock screen stayed on randomly...
Look slike using double tap to wake with notifications or not, keeps the display awake - it doesnt turn off after no use
i get it!
Same here.. lock screen and sometimes just stays on randomly. Peeled off screen protector wondering if that caused some issue and it still happens. They need to fix this.
