[Q] Use camera LCD for nexus 4g notification

Is there an app available to turn the rear lcd on the nexus 4g into a notification light. I tried noled from the market but it is crap because it actual leaves your screen on the entire time. Battery waste!. O yeah I don't want to bother rooting my phone. Please help.

What do you mean by rear lcd? I know there is BLN, but that requires root I believe. Don't know of any others. Someone suggested making the LED flash into a notification light, but I don't think anyone has made one for the NS.

I would think the LCD is more of a battery waste then the screen running.
BLN is the way to go.

The screen uses the most battery on the phone constantly. There should be plenty of people who do not want to root their phone who would benefit from an app that uses the rear camera lcd as a notification lcd. This LCD blinking on/off would use far less power than the screen constantly being on with the noLED app. Can somebody who knows more than me write this simple app? Please Please?

It's an LED, not an LCD. I think that might be causing confusion between people.

Hmmm....I wonder how much juice the flash led would suck up?

OP use BLN it uses the light source from the capacitive keys not the screen and you can customize
also using the camera LED you would have to have your phone face down to see IMO its un natural considering the phone has a curve to it and inconvenience not to mention the risk of scratching if you dont have a case

That hurts just thinking about it laying face down. Any way, @tmorisol I've been using noLed and haven't noticed a difference in battery consumption. I'm coming from an evo so I know what its like to try to conserve battery.

You should only use NoLED if you have a Super AMOLED version of the Nexus S.

[Q] Sensation dried, backlight not working

So my Sensation had water poured on it and it didn't work.
I managed to dry it out and now everything is working, except the backlight. In a brightly lit room, I can roughly see the display, and can make sure that touch and vibration is working, but the backlight doesn't switch on, so the screen is barely visible.
In a dark room, I can see that the capacitive buttons backlight works perfectly, and is still quite bright. So the only thing I can see in a dark room is a white light from the bottom of the phone, and nothing on the screen.
Also, charging works. Booting into bootloader works, but of course the backlight doesn't work too. I had to look into it in a lit room at a certain angle to see it
So now the question is: What is are the possible problems, and is there a possible fix?
Is there a chance of a loose wire, or is the backlight spoiled and require a replacement?

It's hardware related, and yes, it's fixable. AFAIK the baclight is a part of the display itself, so a replacement might be required. However this could also result from bad contacts. you can try replugging your display (there is a guide of the procedure on iFixIt). And the problem might be in the socket itself (in the motherboard).
You are quite lucky to have your device almost fully functional. I suggest trying the second method (trying to reconnect the display to the board) before buying a new display, is it might solve it.
Good luck.

Here:

It's a guide for repairing a broken screen. but it explains how to open the device and replace it, so it's good.
Just remember to follow it step by step, as pulling the wrong component might cause permanent damage to your device.
Good luck

LCD backlight not working

Hey guys,
So, long story short, my phone received some water damage.
As soon as it happened the screen backlight began to turn off and on randomly. After about 5 minutes the backlight was completely dead and wouldn't turn on again at all. The LCD and touch is still working - only the backlight is broken.
What im wondering is whether this damage is to the LCD panel itself, or whether it could be damage to the motherboard? is there a way for me to test or check this for myself?
If anyone has any useful information or knows any possible solutions to this problem i would love to hear it.
Thanks

The backlight fuse is located near the lcd connector, bypass that

The fuse near lcd connector is for display not for backlight??

There's 2 fuses (V) below the connector for backlight and (L) beside the connector for display,
and further components for backlight are present in the area near CPU (diode and coils)

X2 Pro Screen burn?

I'm using CN X2 Pro, 2 weeks old. I noticed that I get 1-2 seconds of ghosting/screen burn from the always on display when I unlock the phone. I still see the dark numbers on my light background. This fades after 1-2 seconds but I've never noticed this on other phones with AoD's? Do you think it's a sign my display might suffer in the future?

I have the same issue with AOD turn on, there is a ghost effect and disappear after few second. I found if you choose dimmer clock color, there is no issue. So, try switch to different clock style, try avoid those white color clock.

Hi. I have the same problem. What do you do guys? Other light spot and the same trouble

Hello. I think its's because of AMOLED screen.

I started getting it with AOD after updating to Android/ColorOS 11.
Previously, the AOD would move around the screen so it didn't happen.
I've had to turn off AOD because of this.

And what do you do? Send to service or something?

Interesting. Yes, prolonged static displays should be avoided.
AMOLED screens do not suffer from burn in. They degrade over time from usage.
They have a long but finite life span.
High screen intensity is the biggest degradation accelerant plus time. High heat ie sunlight should be avoided when possible.
The highest energy blue pixels burn out first, lowest energy red pixels last.
Damage shouldn't be observable in a screen so new. These screens are rated for thousands of hours.
The ghosting may be a firmware glitch and nothing more.
Avoid using over 50% intensity except when needed.
Don't use in direct sunlight except briefly.
Make use of black wallpapers and dark mode as much as possible. Whites and blues should cause the most damage. Reds the least.

So what do you suggest? Warranty, hard reset or just learn to live with it. can update help you think?

A hard reset will do nothing but waste your time and patience.
If you really have damaged pixels, warranty as the display is likely defective.
If it's not actual physical damage only a firmware update can fix it. It may take months or never come at all. So again, I send it back either to be fixed, replaced with a new unit or a 100% cash refund. Nothing less.
Use screen testing app like this one:
Display Tester – Apps on Google Play
Test your screen and figure out whether it has hassles.
play.google.com
I use Screen Test but can't pull up a link. Playstore may have pulled it... as usual.

I guess I will only send the problem is that I bought it abroad and it will probably take two months

That sucks. If the problem is physical it may degrade rapidly; a new display shouldn't have these symptoms.

if there is a bright point, you can see it for about 5 seconds on a gray background. the brighter the screen is, the clearer it is. after a while it disappears

Sounds like hardware. Either way unacceptable.

Question about screen dimming

hey guys got question for u all
i like so much the flip 4 but i sell it cause i had 1 major proble
i bought iphone 14 pro max but i really want my flip 4 again
my problem is any time im using the phone for facebook whatsapp and regular stuff with regular use (not even hard use at all)
the screen dimm to much cause the phone is warm
if i turn on the extra brightness its dimm alot faster with minimum use
so i i never used the extra brightness but always on the full brightness but i always use minimum use and the screen is dimm
any solution or its like that???? (the phone is ok i had 1 before and it was the same)
i have no case nothing i never pleyed games with my phone just regular use....any tips for what to do or this is how the phone act?
and just for you know im on android 13 latest thx for the help !!!

sounds like you have some sort battery saver turned on, have you checked in settings? this is not normal behaviour.

It is clear that your mobile phone has a technical problem that needs maintenance, but try to return it to factory settings

maybe i use app that make the phone to hot the the screen dimm?
im using whatsapp facebook instagram and messanger maybe? anyone knows?

On the Flip 4 I use the Adaptive Brightness "on" setting, and Dark Mode. Your results may vary, but here's what I've seen.
In the summer, on a sunny day, I'll notice that the phone will automatically try to be as bright as possible, so the screen is readable. (I'm pretty sure when this happens the quick display panel's screen brightness slider color changes to orange. Maybe the color depends on the wallpaper/color palette.) And I never see the screen do this "extra bright" thing indoors. Only outside and only in direct sunshine.
So far so good. I think this is as everyone expects the phone to operate.
Given all this, sometimes I'll notice the screen brightness will vary, even though I'm still outside and still in the same brilliant sunshine. I've noticed this commonly when checking Google News, and for example, I'm reading a story and scrolling slowly through the article. In particular when the screen is mostly black text on a white background.
So, in this situation, that is, a largely bright background, in the bright sun, my phone will both:
Get warm to the touch, on the back-side of the phone, where the two batteries are, but not up where the cameras, CPU and memory are located. This makes sense because "scrolling text" isn't that demanding on the CPU, but I am driving the OLED screen hard.
Also the front of the phone (the OLED screen itself) can feel warm. Even in the screen's crease, away from the battery. Since the image is mostly white, all the OLED dots are "on" and give off heat. Then again, I'm in brilliant sunshine and almost any surface will get warm.
Further, I'll notice that the phone screen will automatically get dimmer after a bit of time (perhaps a minute or two of extra-bright before the dimming). This I attribute to the software doing one, or both of:
Dialing back the screen brightness, to prevent OLED burn-in.
Dialing down the power usage by the screen, to prolong battery life and/or limit the battery temperature.
What's more, after little more time, still in the same bright lighting conditions, perhaps reading the same story, the screen might be noticeably extra-bright again. It's as if the phone has given the display "a rest" and is willing to go "extra bright" again.
In short, I think the phone screen is trying hard to be brilliant in the brightest of sunshine. But there are limits in how hard you can drive an OLED screen, and how long the battery can power the screen.
All of this before we start to talk about what design limits come into effect when the CPU or graphics processing come into play, both or which compete for:
Power from the battery, and
The ability of the phone to keep itself cool.
This phone's form-factor is all about folding in half. A slab form-factor phone, I suspect, will be far more capable for heavy CPU, graphics, and provide a bigger battery and better heat disipation.
