I recently got my LG G2 repaired after shattering the front glass by dropping it on the street. The repairer seems to have done a half baked job. After repair, the brightness of the screen is unable to go above 50%. Raising the brightness slider up to 50% raises the real brightness of the screen normally, but past 50% there is no perceptible effect. This is not just me not "seeing" the change when it might still be there. It used to be that the slider was calibrated in such a way that the last 50% had a way bigger effect than the first 50%, so at 50% it's more like the brightness output is 30% (which makes my current problem extra annoying). The brightness is supposed to really take off past 50% and now it refuses to.
Just curious if anyone with technical hardware know-how knows what kind of defect causes a problem like this and whether it's possible to solve it. Thanks.
Maybe it's one of those chinese screens, or just broken one :/

Anyone else seeing this?
I could have swore that on my first Nexus device (RMAed due to bad speaker), I could turn the brightness all the way down and use the tablet on the lowest setting.
On my new Nexus (no issues so far), if I turn the brightness dial all the way down, the backlight totally shuts off, causing the screen to be impossible to be seen.
I'm not RMAing this one because it's perfect otherwise, it's just very weird behavior
I got the brightness on mine all the way down & the screen isn't off.

Did you find a solution?
I have the same problem. If I turn down to minimum brightness (10% or less) my screen goes black. The only way I can see what's on the screen is if I shine a light, and then I can barely make out what the screen says. I assume this is an easy software fix. Also, if auto-brightness is on and I'm in a dark environment the screen will occasionally dip to the lowest setting and turn off.
I'm on my second device also. My first one had bad screen lift, flickering and occasionally screen glitches with black lines flickering through the screen. This one had no noticeable screen lift out of the box, but I'm reserving my judgement, as the device I just returned was fine for the first few hours and then got worse as I used it more.
I have both devices side by side, since Google mailed me the new one first. Comparing the two, I notice the old one's screen is slightly brighter, maybe about 10% or so, but definitely noticeable. Also my new one has a little bit of bleeding on the left side; not terrible as some pictures I've seen, but definitely there.
Update: The screen flickering returned, so I just requested a second replacement. This is actually ridiculous.
Hi all,
I have a visual disorder known as PMA ( Persistent Migraine Aura). Simpy put, my vision is extremely sensitive to all light forms.
The S4 has really bad backlight flicker, especially in low conditions I can see the flicker. It's really horrible for me as I see it more than the average person would. I couldn't believe it had such prominent flickering from the backlight LED's (low refresh rate?) when I first got my phone; I recently sold my Laptop as it had a poor LED backlight panel.
Now to my question: is there any rom out there that reduces this? Any way of reducing this flicker (increase refresh rate)? It's really making me considering selling the phone
Any help will be appreciated.
Hello all I could really use some help, had a vs980 for a while now and it's been through a couple drops and a screen change before the screen change I noticed my brightness would completely die and get really dim from time to time and a good smack would bring it back then it progressively got more frequent to need a smack until finally it didn't get bright. I mean I can see the phone indoors and outside in the shade but any kind of light and sunny days it's almost impossible to see phone. I was still using it putting off screen change one day dropped the phone and damaged digitizer in a portion of the top screen no crack in screen and no damaged LCD just a portion of the top that I couldn't touch to activate apps in that area or a couple numbers I couldn't dial. Finally decided to fix the screen expecting the brightness to be fixed but the problem still persist when I move the brightness slider it doesn't change at all. Nothing it's one constant brightness and dull, I can see it indoors and in the shade outside. But in any relative brightness it appears black and can barely see anything, is there some type of separate backlight besides the LCD digitizer that needs to be repaired also? I could really use some feedback thanks in advance!!!!
I came from a Nexus 5 and had to always leave my screen brightness on about 1/3 in order to preserve battery. After playing with my 6P for over a month, I feel like the battery can handle a brighter setting (with my usage). But, I have concerns about burn-in if I put the setting too high since this is an AMOLED panel.
What brightness settings are you using and have you had any issues with burn-in?
I will get this started. I first started by activating the Adaptive Brightness under the display settings.
It makes the screen dimmer - to my eyes even though it sets the overall brightness to exactly half way.
I thought my whites looked somewhat grey at that setting so I turned it off and put my screen back down to 1/3 (LOL) and I am pleased with the results - especially at night as the whites look whiter.
anything past half at night burns in my retinas much less the screen.
I have not noticed any less Screen on time. I still get about 4.5 - 5 hours until it hits 15%. This is with location turned on and email push. I don't use twitter, facebook or any of those social apps the young people are using these days.
Is there an easy way to dim the screen to the point where you can't see the picture? I stream the phone in my car, which means it will get hot with charging, screen on, and high usage simultaneously. Since it is an AMOLED screen, it would not allow for screen off like other devices. Seems like without this, burn in would be a big problem for me.
I would think that you could just do the 2 finger swipe to bring it to the default menu. Then set the slider down as low as possible until you can barely see anything. I took a 5 hour drive today with my Nexus 6P with the girlfriend and had it plugged in for at least 2 hours at a time. My phone did not get really warm while either plugged or when running on battery.
Also I have enabled the System UI Tuner and now my phone screen only stays on when plugged into the power source if I select "stay on when plugged in"

No burn in issues? I would think there is a way to reduce brightness beyond stock but I don't know enough to do that at this point. Perhaps through Xposed it something.

I had a gnex that I kept on low brightness and refused to get another nexus until battery was straightened out. On my dmaxx, I kept the brightness high and no burn in on the amoled. The 6p isn't as good at battery, despite being huge, but it's good enough. I keep it on 60-100 brightness, using lux to adjust it as needed. No burn in so far
I keep my screen brightness very low and I have had it happen a few times in low light conditions where the screen will go into full seizure mode and start flickering. What I have done is then increase the ambient light around the phone and the flicker stops. I read of a few others on the Lenovo forums with the same issue but no official problem acknowledged yet. Anyone else here have this issue? I am not sure if I should send it back since it is a new device. I worry about future issues and longevity.
I got my phone yesterday and noticed after using it for few hours. It only happens at certain brightness level with Adaptive brightness On. I haven't noticed it after that. I use manual brightness mode and from what I read on lenovo forums that it doesn't happen with manual. I was thinking of replacing it too but after reading so many users complaining about it I am sure this has to do with software. Also, I noticed random WiFi disconnection.
I hope they push out update for all these bug fixes.
EDIT: My sister has the same phone since May and she noticed it too. So, I am pretty sure it is software related issue.
The issue is most probably due to PWM, since Moto G5 (and Plus) use it at low brightness: https://www.notebookcheck.com/Test-Lenovo-Moto-G5-Plus-Smartphone.213428.0.html (german, use Translate)
The display flickers at 2404 Hz (most likely due to pulse width modulation PWM) at a set brightness of 3% and below.

It cannot be disabled (practically) by software means, it's the way the display driver controlls the brightness (because of cheap components). It's also present on 99% of AMOLED displays.
It causes eyestrain and headaches for a lot of people (I am one of them). The site above (also has an English version) checks for PWM on all reviews, so you can check other phones if you want to replace the G5.
