Blinking dot under selfie camera appears on custom ROMs (just lockscreen) - Samsung Galaxy A40 Questions & Answers

Hi! I have a Galaxy A40 and i didn't had that problem with the stock rom, altough i read that even the stock system can producate the same issue.
I'm on the crDroid 9.0 Android 13 (the rom is incredibly good though). In the past i've tried other custom ROMs and a few of them had that issue but not just in the lockscreen but systemwide.
Fortunately in that case the dot blinks only on the lockscreen, and its not that visible with a darker wallpaper but it's still annoying.
(I've also noticed that if [not in the lock screen] the screen has a brighter image front of the sensor the auto brightness goes up and if it has a darker image front of it, the brightness will go down... It's maybe not the case and I saw that wrong but hey, idk.)
I have two questions about it, I would be grateful if anyone could help! :3
1.) IS IT BAD FOR THE HARDWARE?
Its maybe a stupid question but a constant flickering is not a calming thing thats for sure...
2.) IS THERE A WAY TO SOLVE THAT PROBLEM?
Are there fixes? Flashable zips, apps, mods or anything that is should try to make that disappear? Or I just shouldnt have light backgrounds anymore?

Thanks~ xoxo

It's required for the proximity sensor which is mounted behind the screen and needs the black dot to see through (I think!). Sadly doesn't look like it's fixable but it doesn't harm or cause issues other than it being a but annoying to look at. I think the flash we are all getting in these open source ROMs is a workaround for not knowing the exact matching frequency of the sensor.

Camera problems

Hi,
Been using various itje roms since i got my phone (but 8 months ago) I noticed after I put on the touch vista rom that my camera was taking awful pictures. I dont think it should be rom related, I just tried the touch 7 rom and it was the same. I prefer the vista one so ive gone back to that. Is it worth going back to an official release and trying ?
Ive gone through all the settings, its on 2MP shooting to sd card, on single shot mode (all modes including video have the same look) Ive checked all the settings i can think of. Whitebalance is auto. Effect is None. Quality is 2M (1600X1200) Fine.
Ill attach a picture to show you. I really hope it is software based and not the camera itself. Phone has been well looked after so it really should not be damaged. Externally it looks fine.

honestly i would try touch it 4 and see what happens
but when you say it takes horrible pics is it blurred like give us a discription
I included a picture which I thought was fairly self explanitory. The pics look like they have been posterised. The colors are separating distinctly, almost like its working with a limted colour set.
well it could be that the connection from the camera to the phone is a bit outta place but dont quote me lol
i work for motorola XD

less camera light

is there any possibility to reduce the camera light?
if i take pictures from faces, the flash uses his full power and messes up the picture. there is an example:

On my Sony Ericsson K800i the kamera did send out a light to get the focus and took the picture with the flash light...
anyone knows good settings to take pictures at darker places?
also the hd2 has a quiet bad image stabilization. did someone experienced something diffrent?
The TMoUS camera drivers fix the LED flash overexposure problem so all you have to do is find a cooked ROM which uses them.
I used to have a k800i too, the camera is far better than hd2 due to its xenon flash (better light management) and very short shutter time (reducing blur).
If as NeoGreendawg says the US rom has a fix then its only a matter of time till its fixed officially over here.
Right now i use a program called Torchbutton which turns the led's on. Then run camera app and set flash to disabled. The torch gives enough light but without the superbright flash that kills the pic.
Look on the sticky application thread in hd2 themes & apps for torch button.
As for image stabilisation i guess we just have to hold the thing damn still

Help Me make my Screen Bleed again!

Good Day Everyone
did anyone of you owned a S4 back at its launch? Then Maybe you can remember the struggle with it's Screen Bleeding/Smearing all over the place whilst scrolling up n down a list. The pitch black background was to blame for this. Not able to light up quick enough. Well I Themed my N9005 with All Backs Black which itself is a lovely theme. But many system backgrounds like the Dialer, Contacts, File browser and Settings etc. are a dark gray color which annoy the s*** out of me. After theming it with All Blacks Black the dark gray background is very noticeable to me. Here is a sample
I intentionally made it a bit more visible for non amoled screens

}
I've tried replace .png's like tw_background_holo_dark and tw_background_dark but sadly that didn't work like it seems have for many people on their S4's according to @bala_gamer over at his thread ( i know they try to get rid of that effect in that thread but at the bottom of the first comment he shows a method to reverse the "fix").
I mentioned my desire on the All Blacks Black thread and @Kdio suggested that maybe messing with the right .XML file would help, but I have no clue which one I have to edit.
I know getting the background to black would cause smearing/bleeding (whatever you wanna call it) but I'm fine with that.
I would be grateful if some one could help me out with this issue and knows what to do.
May the odds be ever in your favor! Peace Out :fingers-crossed:

Note 4 Display turns on by itself or minimal touches

Hello, friends of the Note 4.
Im note sure if i am right here to ask about a specific problem.
Like i mentioned in the headline, the display of my phone turns on by minimal touches it seems, for example if i take the phone in my hand but not puch any button. Can be that it also turns on without toches, im not so sure.
The effect is hardly reproducable though, by handling the phone rougher just to see if the display turns on. Not sure.
Im a little stumped by this problem, since it didnt changed by flashing another rom. Im a little afraid that it could be a hardware problem... Hope not.
Do you have any advice for me what to try or in what direction to look for a solution?
Thanks!
Quick Glance on for some reason? LOL!

What even is Quick Glance? I use a Note 7 rom, by the way... Just truned off smart stay. It will take time to see if it solved the problem.
I think this problem is related to the apps that can appear on top like pie control, drup or any other 3rd party apps. So try to disable them one by and see which app is causing this problem. Cheers

Thanks for reply! Honestly, the whole Apps hat can appear on top thing is a super bother. I dont really understand the sense of it. Yes i will try to disable all.

Screen off, intermittently flashing LED? o.O

Hello guys. Which sensors are on the front of telephone? I was taking pictures for a guy who asked me the photos of the phone, so i took a couple of it with the second display off/on, and I noticed that there is a small LED that flashes intermittently when the phone is switched off the screen and some time when is on, below the front camera ... to the naked eye you do not notice it, in fact i have never seen, but if using a camera you see this LED that blinks continuously. With the phone turned on does not do it, only when it is switched off ...
It is not any reflection, I used two cameras and from different angles you see the same LED always flashing in the usual place ...
Does anyone know if it is normal this thing ??? Thanks

It's the proximity sensor.

But it should not go ON only for calls?

Nope, that behavior is completely normal.
The proximity sensor is also used to prevent the use of the power button and the fingerprint scanner when the is zero light. Personally this annoys me since I came from a Nexus 5X, and unlocking the phone in my pocket gives a feel of a faster unlock.
Great, thank you all for the answers. I was already worried lol
However Note 5 did not do it ... meh!
Thanks again!
