Question Torch is almost dead (v.dimm) - Samsung Galaxy A72 4G

My phone's torch suddenly went very very dimm, I can only barely see it in dark. Any idea if LEDs are gone bad? Or is it something else.
have already tried changing the intensity of light from torch settings but that didn't make any difference.

Try to factory reset. If the problem persist, go to service

Possible SOD issue...

Hey guys so my Tilt 2 has been having an issue when I put it to sleep. It goes to sleep fine, but when I wake it up the screen remains black. The actual device turns on, but the screen stays black. I can still make calls, receive calls, play music, etc. but I have to soft reset the device if I want to be able to see what I am doing.
From what I can tell my problem is different from the normal Sleep of Death issue where the device simply won't wake up.
I've searched through the forums looking for solutions and have tried pretty much everything from doing a hard reset, using different roms, formatting the internal memory, etc. Even after doing all of this, my device still suffers from this issue.
Any insight into my problem would be greatly appreciated!
I assume you've tried a simple reset using the reset button or pulling the battery out and putting it back in?

Yeah every time I the screen goes black I soft reset it in order to get the screen to turn back on. The problem is that the issue persists through soft resets. I currently can't suspend my device because I can't get the screen to turn back on...
hold down the volume down button and then press the reset button (the physical reset button) this should bring you into your bootscreen the multicoloured screen.. if you can get there then you can flash a new rom on your phone... and thats a whole other ball game. It gets a lot of hype as being hard but its really super easy to do if you just follow the directions.
Tilt 2 dark screen solved
With the tilt 2, if the screen does not wakeup, but you can answer the phone, hear music, etc..., it is a malfunctioning light sensor, maybe hardware, or software related (drivers), but it is fixable. Just eliminate all calls for use of the light sensor.
I had this problem and took quite a while to figure it out, as there are several apps that poll the light sensor that cause problems.
First, go to start/settings/system/power/backlight and uncheck the auto adjust backlight option
Second, go to start/settings/personal/buttons/backlight and uncheck the enable keyboard auto backlight sensor.
Last, open advanced config (need to download and install from touchxperience.com, if you do not have it), tab to light sensor and set light sensor polling to disabled.
Now, my phone works normal and will wake up properly from standby like it should. this all seems hardware dependant, as I have in my family 3 of these things and I dropped and broke mine, so bought a new one (4th in the series) and it had the SOD issues, but could restart with softrest. Took me the better part of the day to find a reliable fix, but now all is well again.
Hope this helps other Tilt 2 and similar issues.

Keys don't light up

Hey there,
my screen was broken and i fixed it by myself (i had no warranty anymore, so...)
Screen is working well now, but the keys on the bottom won't light up.
Anyone has experience with that and could give me a tip, what i could do?
Thanks,
Prexx
I am using Miui, and there are settings to manually calibrate brightness levels and key light levels. You should check that out
My first guess is that you somehow accidentally might have disconnected a cable which leads to the lights. You might want to open it up again and recheck all connections.
check if its a hardware prob or software try several roms of the same results i suggest u fixe the light prob in any htc center

BEWARE!!! YUREKA stock cm 12 users

This bug deserved a new thread.
If you've updated your phone to cm12, 5.0.2 then DO NOT DO THE FOLLOWING:
1. in Settings>Display and lights DO NOT keep "Adaptive Brightness" and "Color Enhancement" switched on at the same time. If you do, and then EVER try to manually reduce the screen brightness to minimum, YOUR SCREEN WILL BO BLANK. PERMANENTLY. Not kidding.
AND IT WILL NOT RETURN TO WORKING CONDITION without a factory reset.
Things that won't work:
1. Pulling out the battery and trying to reboot it. Nope. Been there, done that.
Hope CM takes note of this.

Cure for it
well i have experienced it. but to avoid it you can choose the option
setting>status bar> and check Adjust brightness by sliding across the status bar.
so whenever the screen turned off you can swipe on the top from left to right so that brightness can be adjusted again!
you dont have to reset your phone.

happened to me also.... I thought it was a problem with a theme... so i initially rated it 2 stars on play store, but after i saw it was a problem with cm, i went back and gave that theme a 5 star rating...
SOLUTION!!!!
It is still possible to take control over your phone in this situation. If your screen goes blank, this doesn't means that your phone has stopped working, the phone is still functional and you just have to find a way to increase the brightness. If you ever encounter this problem just swipe the screen twice from top to bottom to open the status bar and then slide your fingers on the screen where the brightness controller is present. This will surely solve your problem without any factory reset bull****. Please note that during this complete process the screen will remain blank. I have tested it a hundred times and it works 100%.
this works ... instead of factory reset

how to set the display contrast
or colour enhancement
in yu yureka
Just install vysor in your pc and plug your phone to the pc. Now control your phone using your pc and increase the brightness same wy you reduced it. No need for any factory reset. Hope this helps.
you should Try this
Facing The Phone to Direct Sunlight or if in the night. face it near to the bulb. It will adapt light from the bulb and screen works then you can turn off adaptive brightness. That's works for me.

Screen is yellowed, but goes back to normal when opening some menus like Settings

I'm facing this issue since yesterday. I think that was after I actived reading mode, night mode or something like that, but couldn't find it anymore.
When I press the Settings button, for some milliseconds the color goes back to normal, with a neutral temperature. Then I open the notifications menu, it turn yellowish again; and neutral when I close the notifications. But turns yellow again when I close the Settings.
What's happening and how to solve it?
Are you using cyanogen? If so, try turning off livedisplay in display settings. If it doesn't work, try resetting your device or change to another rom. If it still doesn't work, then I guess it's a hw problem.
IIRC there's a night mode in stock. Could you post details about your phone?

Make sure the Simulate Color space is set to disabled in Developer Options

Uninstalled CM Locker, it was solved. So it's probably an option within it. But I'm not using it anymore.

Ambient display (always on) flickering a middle brightness

Got a Pixel 2 xl off ebay and everything seems fine just the ambient display (always on) screen flickers at middle brightness. In the dark it is fine and the bright light it is fine just mid brightness I can notice it. Has anyone else noticed this? Pretty happy with the phone so far and know the camera will make up for anything just find it pretty annoying at times.
Also the fingerprint sensor is random, sometimes it works other times it won't recognize the print others it says the sensor is dirty. Thinking this phone has a couple of hardware faults and that I should sent it back but for £300 I don't know if it was worth it,any thoughts??
Did hard rest no luck with that so going to try development package, then maybe custom rom to see if they can iron out the issues.
I disabled "New Notifications" toggle from the Settings which keeps the ambient display on but does not wake the phone up and show lock screen for new notifications. Seems to work.
I guess the problem is about this new "Silent Notifications". You can not see them but they come and go momentarily waking the phone up.
