[Q] Omnia pro b7330 background light of screen. - Omnia II General

Hi folks,
I got a very strange problem of my Samsung B7330(omnia pro):
Once my backgroud light of screen is off, I can not wake it up anymore...That's crazy cuz I have to work without background light, I can see nothing.
The only way now I have to keep background light on is restart the cellphone and keep typing it...
Is there some one have the some problem and can give me some advice???

I got a quick solve : Setting - Power Management- Set first 3 to NEVER NEVER NEVER. Than it's ok, but I think this is not a good solution.

Hi, on i8000 there are more settings for display-light if you klick on the
battery-icon in the top right corner of the startscreen.

Bricked Trinity?

HI all,
i have an SFR300+ also called Trinity. I never customize him or anything. Since this morning when i turn him on , the green led turn on and turn off but the screen is black with light on(retrolight? in french retroeclairage). if i turn him on and clicking some button it appears the "very nice colored logo SFR" but he is blocked here. when i turn him on as bootloader mode, he turn on but always with black screen and light on.
i don't think it is the screen cause i saw it ok.
when i try a hard reset i saw options, i make it and he's trying to reboot but black screen and light.
i try unbrick with splxploit but it doesn't work. and with -c 1 and 2 and 3.
I hope there are some way to my pda
Sorry for my so bad writing, i try to do the best.
Thank for your help!
Edit [ maybe can help, when i'm on bootloader mode i know it's ok because i can use unbrick, and it's recognize the phone and saw SPL number etc... ]

[Q] screen, black = brownish

hi all, recently came to notice that on my screen black = brownish
strange thing is when i turn off the phone, then turn it back on and don't let the screen go to sleep or press the top button to turn it off, black = black
then i found on google that there are grayscale problems on htc legends specific
http://androidcommunity.com/htc-legend-amoled-struggling-with-grayscale-20100602/
also searched on xda and no fix or really similar problem
tried to make screenshots and photos but you can only see it with the naked eye
so my question is do you guys have it to? and is it software or hardware related and can it be fixed by tweaks or so
grtz

Touch keys light missing

Hi folks!
I've got an annoying, but not that tragic issue with my s7edge.
The touch keys (back and recent apps) light is missing.
What's funny - when I reboot the phone and the phone boots up - they DO light up, but after few seconds the light goes away.
Moreover - if I change the delay of its light in Settings (yes, I know I can change the settings of this light) - for example, to 1,5 sec - they DO light up for 1,5 sec but then the light again goes away.
In short - the light should work everytime I touch the phone screen, but in fact - it only works for few seconds when I am changing its settings.
Maybe I'm an ignorant and there is some option in the custom kernels that keeps the lights off? Like some battery saving feature or something?
I have tried disabling all Xposed modules, changing ROMs (now I am using KingROM), kernels (now using SuperKernel) - with no effect. I cannot remember if the light were shining on the stock ROM, as I had it only for few days.
Or maybe I am just super stupid, because this is intentionally changed by custom ROM developers?
Is there anyone with the same issue? Or maybe there really is some stupid settings that I should simply change? As I have previously said - I DO know about the settings of the delay for the light of touch keys - it doesn't change anything.
Thanks!

Try this app if it can solve your problem:

Unfortunately, it works similar to the original settings - when I change the duration, the lights do light up for (for example) 3 seconds, but then they would turn off and never light up again (until I change the settings again).
It seems like something's broken in the ROM I am using, but no one else using this ROM (and the previous one I had) have experienced this issue. This is strange!
Oh Lord, I just totally accidentally have found the solution... The thing I had to do was to disable "one touch mode" in Accessibility Settings... Few months with this issue and the solution was so easy :E

A5 2016 sometimes won't wake up, screen flashes

Hi,
I have this phone for little over 2 years. For over 1 week now I'm experiencing my phone not being able to wake up when I use the power button/home button. Whenever I push the button, the screen flashes for like 1s blue color, you can also see that the notification panel is blacked out and part of it green and it doesn't wake up. Sometimes it doesn't even flash. It used to take about 10 tries to wake it up but today I couldn't wake it up. I performed soft reset, I couldn't see the booting animation at all but it rebooted, buttons lit up and I was able to get in. It's like the phone is working fine in the background but the screen doesn't light up. I can turn down/up the volume, take a screenshot, get into settings, open apps, write a message but the screen is black. Even my alarm went off this morning but I couldn't dismiss it.
I downloaded an Always On Display app. Although I don't actually see the screensaver when it's locked, it's still on and it's easy to get in beacuse of it.
It all started with the screen flickering on minimum brightness. In February this year I had the screen replaced for the same issue but this time it's worse because of the blacked out screen.
Any ideas what it could be? Faulty display again?
Thank you

It's over to have this phone for little over 2 years now you should have to change
TIP:
Flash a new stock rom of your phone from sammobile via ODIN.

That would be great, but I'm not a person that buys new phone every 2 years. I was thinking about it though .
When it comes to flashing. Do you think that would help? I don't want to end up with a black screen unable to set the phone up again. Cause overall it's working great .
Hi, i have the same problem, i'm from Belgium, and I have blinking screen problem and wake up screen problem :s
is it a software issue (nougat???)
before the big update (marshmallow i dont have any problem)
i'm on firmware A510FXXS7CRJ6_A510FLUX7CRJ1_A510FXXU7CRJ6_HOME.tar.md5
Turn screen brightness up abit to stop the blinking of screen. It's an issue of the screen hardware itself at low brightness after wear and tear. As for the hanging issue, maybe it has to do with your AOD app? Try uninstalling the AOD app OR flashing a stock Rom OR custom rom OR factory reset and use your phone at a higher brightness that the screen does not blink and see whether it still persists.

Thanks, because of my past experience with the same problem earlier this year I know about that "solution". Unfortunately, it makes the battery die faster as expected. Which is sad because I used it mainly on low brightness. So it's really not a solution at all.
I got rid of the AOD app because I found out that the phone lights up on 2nd try. AOD didn't work at all. I have to wake it up, put it to sleep and wake it up again which is always successful and the screen lights up. The screen flashes white about 3 times in a row now otherwise it works.
I haven't flashed it yet although I wanted to. But I will see what can I do. Thank you though!
I'm having the exact same issue using LineageOS.
It's already been 2 years, but since this thread is one of the first results on Google, I'll gladly add a solution.
Exact same problem for me, went through two screen repairs under warranty, and it would always come back a year later. No difference between Samsung OS and LineageOS, though I haven't tried rooting it.
Found on Ifixit: this issue is related to the AMOLED screen technology used by Samsung (among others). You can look it up, apparently there is a bad (?) voltage management in low brightness which worsen with time.
I could fix it with the "OLED Saver" application on Play Store. It works around this voltage management and allows you to reduce the brightness without the green flickering.
I still got white flashes after the installation, but not anymore the day after. I could even disable this application without the issue coming back.
I don't know what kind of magic cleanup this app performed, but it really is a (screen) life saver.
