[GUIDE] Green Screen Issues on MIUI No More!

Hey Guys,
I have figured out how to get rid of the ugly green screen issues with 3rd party kernels for MIUI.
Goto Settings
Display Settings
Turn automatic brightness on
Adjust the slider until the screen is at the lowest (before it turns green)
Go into advanced mode
Turn on Use Custom under Light levels
Light level to dim - set to 10
This should fix all the issues with green screens!

I never had any green screen on miui, with official or neo/vorbeth/glitch kernels.
I was curious and tried what you posted above, and I can't do step 4
3. Turn automatic brightness on
4. Adjust the slider until the screen is at the lowest (before it turns green)
If auto brightness is set to "on", I can't slide..

That's odd, maybe the new versions fixed this problem. I guess coming over from cm7 if you have custom brightness it will turn to green with miui

it worked, thanks! my dim level was set to 5, changing it to 10 worked perfectly.

strange... never had this issue when i was on miui and that was yesterday.

i have the same problem, i went at a local repair store, and the guys overthere told me that the colour module is broken !!! anyone knows something about this???
they say that in my case i need to replace the screen in order to fix this issue... if anybody have other idea...
thanks in advance !

[Q] Auto dimming my car mounted Nexus 7

So I've been doing some general googling, and I haven't come across a good solution for my issue, so I thought I would post it here. Nexus 7 is mounted on the dash of my car. Powers on and powers off (deep sleep), connects to hotspot fine, generally, is working great. HOWEVER, there is one feature that I would love to be able to replicate from OEM in dash systems that I've seen. I would like the screen to dim when the unit isn't actively being used. Not time out and go to sleep, just dim (or maybe even turn off the LED backlight). Then, when I tap the screen, I want the screen to come back to automatic brightness mode based on the ambient light sensor. I've found plenty of apps that will turn the screen on or off with various gestures and such, but they all seem to require disabling or otherwise changing the way the ambient light sensor works. From those of you that use these in your car, I'm hoping that you have some suggestions. Thanks in advance.

Hi, bigdogbts...
What you suggest certainly sounds feasible. I have no immediate solution, just some ideas/pointers.
Three pieces of software come to mind...
A Custom Launcher such as Apex or Nova. These give you a double tap gesture on the screen, which you can associate with some action to run... app, shortcut or 'activity'.
Lux Auto Brightness.
https://play.google.com/store/apps/details?id=com.vito.lux
This is capable of reducing the screen brightness right down to zero, such that the device looks likes it's turned off.
Tasker.
https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm
An app which is capable of automating all sorts of things on an Android device. You can associate an action instigated by the the user with a desired objective. Unfortunately, it has a bit of a steep learning curve... I bought it myself a few months ago, and I still haven't got around to really fully understanding it.
I suspect that if you can 'associate' Lux Auto Brightness (set with some pre-arranged brightness settings, ie., a completely dark screen) with a specified action (like double tapping the screen) with either Apex or Nova launchers (via gesture) or possibly with Tasker, maybe via a script...then you may be able to accomplish your goal.
As I've said, I think that what you're asking sounds possible... it's just a case of finding the right apps, and 'stitching' them all together. And maybe with a bit of tinkering with the apps I've mentioned, you can, hopefully, get something that works,
Good luck.
Rgrds,
Ged.

I think tasker can do something like that.

[Q] Is there no "Auto" brightness for Tab 4.7?

Seems like an odd thing to overlook....

No

thanks

It's on the Tab Pro and Tab S

In "Settings->General->Power Saving" there's an option to enable Screen Output Mangement. This will automatically lower brightness to save power...
...not sure if it act as a auto-brightness depending on the light in the room you're in but give it a try!

Pretty weird samsung didn't include auto brightness on all the tab 3 models this was present.

Don't mean to necro this thread but the Samsung+ application (device health monitor?) has a setting under battery life that can trigger auto brightness if you want. My tablet doesn't have a normal auto brightness so I have to use that.

Screen flicker workaround

Hi everyone
I want to share a workaround to all of us who owns a defective S5
Symptom: You unlock your phone and it doesn't show anything. Actually, the phone is working. Capacitive buttons light up and you may heard some activity in the phone
Your phone has a defective screen. There are a lot S5 which have this problem, according to several forums. After several tries, unlock and lock over and over, the screen light up and you are able to use your phone. The problem is when you receive a call and you want to know who is calling you, the screen doesn't illuminate and you won’t be able to know who is.
Here's a workaround which makes your powerful S5 usable and take out from your drawer.
Solution:
The more effective way to fix it is: change defective screen! But sometimes it could cost as much as a new phone, or simply you can't afford it, and it's better to change your phone instead, and you put your S5 in a drawer.
The technical explanation of this problem is: Screen doesn't receive enough electrical current at low brightness levels (maybe the flex is defective, get old, etc)
Most probably the wake up problem exist together with screen flicker at low brightness levels
The wake up problem rises up more in dark environment, when light sensor make low bright screen
The lock screen light up screen, with a dim effect: when you lock the phone, it slowly turn screen off, and when you unlock, it make and effect of dim screen.
When you are is in dark environment, the effect is very slow, preventing the screen illuminate because the technical problem explained before.
When you are in very light environment, you lock screen and sensor light make the screen very brilliant and chances are you defective phone wakes up correctly.
We can use an app which give us complete control over brightness subsystem. I use an app called Velis AutoBrightness:
Once installed from Play Store, it shows a Setting Wizard. Follow the instructions. Below are some notes
• 1/7: Welcome Screen
• 2/7: How bright... Most probably is your phone always have flicker in low brightness. Choose "AMOLED" or "AMOLED bright". By the way choosing any one of those cure always minimum brightness failure!
• 3/7: Choose High sensitivity
• 4/7: On, if you want additional brightness when charging. Irrelevant for this thead. Choose your favorite setting
• 5/7: Same of 4/7
• 6/7: Choose enable: That enable the app
• 7/7: Some additional notes: Press Done
Now important settings: go to Menu > Settings > General: Settings Mode > Advanced
Service Activation settings:
• Disable system handler > ON: When you use Power saving mode, you surely noted screen flicker, which is very annoying, and make unusable power saving mode. By set this ON: Android doesn't set screen too dim; instead Velis have a minimum of brightness set by Wizard 2/7. (Surely you find out that you avoid screen flicker, by setting autobrightness off and slider in 8-10%)
Sensors settings:
• Screen-on sensor value override: Set this value to 30000. Read below this post if you want technical explanation of this setting
After you establish these settings, you'll be able to unlock your phone all the time!
This is the trick: When you unlock your phone, you'll note that the screen is very bright (because Screen-on to 30000) and quickly adjust to the environment light. The failure is that electrical current to screen is defective, and when exterior light is dark, the screen make a dim effect and doesn't light up.
Note to Marshmallow users:
• This app make use of Screen overlay permisions: And marshmallow is very restrict with this kind of app. This is specially true when you are installing an app. All you have to do is deactivate the app in notification screen: press "OFF" button, adjust system brightness upper enough to not flicker the screen, install your app, and activate Velis Autobrightness again
• Because of Doze mode, wake up from this mode may avoid your screen light up, the first time you use your phone. Let 10-15 seconds your phone wake up, lock again, and unlock again, and velis will make its work!
I hope this post make your smartphone usable. I barely apply this trick to two phones, but I think this is a good workaround!

I used this app & the flickering is still available

What worked for me is downgrading the firmware on my g900f all the way back to Android 4.0. My phone came with version 5.0 and I noticed the problem only after I kept installing samsung's system updates. Will report if the problem starts up again but I'm running rooted and running nougat just fine so I don't see a reason to keep upgrading the firmware.
Edit: nevermind, this didn't work

Does anyone know for sure if it's the flex cable or some capacitors? I notice only the lower half of my screen flickers.. I bet there's a simple electrical fix for it instead of replacing the whoooole display

Hello,
Have you change jour battery? If it s old it could cause some issues...
But try to buy a genuine one, I think that your battery must be old now.
Bye

I noticed that screen only flickers at low brightness when using Boeffla kernel for LOS14 and others based on it.
No issue for the same device with LOS or Stock based kernels.

+1 to that , i even went back to stock and the screen flicker appeared and such issues are well known already with samsung amoled panels back in 2014-even some panels from 2018 . So def not kernel related.

I was using los 15.1 and this problem got worse. The phone was barely usable as mentioned by the op. In my case, the screen would start flickering below 60%. Then I switched back to stock marshmallow. I noticed that 100% brightness in los 15.1 is actually only about 70% in the stock rom.
I have been using the phone at 80% brightness for some weeks now and the problem has significantly reduced. But not completely gone, it's much much better. Also, you might want to avoid using dark wallpapers.

cm12.1 live display not working properly

Hi, i have installed cm12.1 in my s3 neo but the option of live display is not working after lock & unlock the device...

Well it doesn't work as it should but it mostly is working. The litle devil have the will of its own so that it sometimes won't do what you told him but eventually it will work including the switch between day and night mode.
For the reference recommendation is to switch it off.

Right, but when i compare s3 neo with other device it looks like s3 neo has radish display not clear white like other phones

On my S3 neo live display doesn't work at all in automatic mode, and I have to set it manually. Furthermore, the minimum level of brightness is too high for my wife's standard sleep level, so I had to install a third-party app

Currently mine disables LiveDisplay every time the screen is turned off. And Automatic doesn't work at all.

Try this script for Automate. It makes it so that LiveDisplay is disabled and then put on auto every time you turn the screen on.

Could you help me do this using Tasker?
